Issues for Congress regarding the Aegis BMD program include the following:

1.  required numbers of BMD-capable Aegis ships versus available numbers of BMD-capable Aegis ships;
2.  a proposed reduction in planned procurement quantities of SM-3 Block IB and IIA missiles under the FY2018 budget submission, compared to planned quantities under the FY2017 budget submission;
3.  whether the Aegis test facility in Hawaii should be converted into an operational Aegis Ashore site to provide additional BMD capability for defending Hawaii and the U.S. West Coast;
4.  burden sharing—how European naval contributions to European BMD capabilities and operations compare to U.S. naval contributions to European BMD capabilities and operations;
5.  the potential for ship-based lasers, electromagnetic railguns (EMRGs), and hypervelocity projectiles (HVPs) to contribute in coming years to Navy terminal phase BMD operations and the impact this might eventually have on required numbers of ship-based BMD interceptor missiles;
6.  technical risk and test and evaluation issues in the Aegis BMD program; and
7.  the lack of a target for simulating the endo-atmospheric (i.e., final) phase of flight of China’s DF-21 anti-ship ballistic missile.

Review of “12 Popular Software Defined Radios”

John Reyland, PhD
Instructor of ATI’s “Signal Processing for Software Defined Radio”
ATI offers two scheduled courses on Software Defined Radios (SDR). Additional courses are offered on-site at your facility worldwide to groups of 8 or more.

Practical Software Defined Radio Development

Software Defined Radio Development- Practical Applications
The schedule for these SDR courses is provided at the link below. Check frequently as additional courses are added based on the demand. If you are interested in courses for the SDR area, please post a comment on the ATI blog and send an email to ati@aticourses.com. Visit:
http://www.aticourses.com/schedule.htm#radar

First we should define what is a Software Defined Radio (SDR). The author of the reviewed article neglects to do this so I will provide a definition. In my view an SDR is a radio system with control and reconfiguration defined by a highly organized SDR frameworks. This frame work reads configuration files and reconfigures radio hardware and software to bring about the desired radio operation. An example of a standardized set of SDR configuration files is the Software Communication Architecture (SCA) domain profile. SCA domain profile is a set of Extensible Markup Language (XML) files that describe waveform components and interconnections. One example of an SDR that meets this definition is at: http://redhawksdr.github.io/Documentation/

This is a useful article on examples of Software Defined Radios and the source of inspiration for this tutorial blog post.
http://blog.bliley.com/12-popular-software-defined-radios-sdrs

None of the radios in the reviewed article meet this strict definition. So here is a simpler definition that will cover most of them. An SDR is a hardware device that tunes to a range of radio frequency carriers. The selected carrier is down converted to an intermediate frequency, filtered and converted to a stream of digital samples. Ironically, this definition does not imply any user changeable software at all! Indeed, there is very little user changeable software in most of these 12 devices. The author neglects to mention that the “software defined” part is written in GNU radio, Simulink or some pre-written third party software (for example, see http://airspy.com ) running on the computer the SDR is connected to. These products are more properly called SDR front end tuners. To be fair, I will admit that common usage seems to prefer calling them SDRs.

A disappointment with these products is that most of them do not have a sensitivity spec. This would be, for a digital signal, the minimum bit error rate for a certain low receive level (for example -100 dBm on the antenna input). For a voice signal sensitivity could be the signal to noise and distortion (SINAD) for a similar low level signal. In my opinion, the lack of serious specs like sensitivity puts these products in the hobby or educational category. A professional application would need a link budget and other parameters like probability of outage. Lack of a sensitivity spec makes these difficult.

Another observation is that most of these SDRs do not tune down into the 3 – 30 MHz HF band, where most of the ham radio signals are. This may be because the tuner chips they use were designed for applications, such as TV and commercial wireless, that did not need these low frequencies. There are a few that offer adapters to reach these low frequencies.

This article provides sparse comments about 12 SDR products. Prices, applications, frequencies and ease of use are given as the reason these 12 were chosen. In what follows I am going to reorder the author’s choices, starting with the products that seem to offer the most usefulness to the average SDR experimenter.

RTL-SDR
This is a low cost (about $25) 24 MHz to 1.8GHz tuner with a USB interface. You can put together a complete SDR receiver by controlling the RTL-SDR with pre-written SDR software (for example SDR#). The well written book “The Hobbyist’s Guide to the RTL-SDR” by Carl Laufer is an absolute must for getting the most out of this receiver.

NooElec NESDR
This is made by the same company (NooElec) and is very similar to the RTL-SDR. The RTL-SDR started out as a TV tuner for use in countries other than the US. The NESDR is specifically designed for SDR use. A primary difference is the TCXO (Temperature Controlled Crystal Oscillator) in the NESDR has much better specs then the cheap crystal in the RTL-SDR.

HackRF One
This is a higher performance wide range tuning version of the RTL-SDR. With 1-6GHz tuning range and both transmit and receive capability, this may be the best value of any of these SDRs. Price is only $299.00. However, for those who want to program receiver DSP into an on-board FPGA, the USRP may be a better value. The HackRF is RF only, no FPGA.

AirSpy
With a $199 price tag, this is another upgrade from the low cost RTL-SDR. However, unlike the HackRF, the 24MHz – 1.8 GHz tuning range is not much better than the RTL-SDR. Also, unlike the HackRF, the AirSpy does not seem to include a transmitter.

Ubertooth One
This is a USB dongle based SDR with better specs than the RTL-SDR. Tuning range is restricted to the 2.4 GHz ISM bands, not as versatile as the HackRF.

National Instruments USRP
This is similar to Ettus USRP. These devices are both based the Analog Devices AD9361 transceiver chip. The Ettus USRP is commonly used with GNU radio and the NI USRP is probably designed specifically for Labview, a block diagram oriented signal processing tool from National Instruments.

Other devices called SDR

The reset of this list has various circuit cards that could possibly be used as SDRs, however they either have high prices or they simply do not include any radio tuning or they simply were not designed to be SDRs.
Red Pitaya
Surprise, surprise, this is not an SDR even with our simpler definition. There is a 125MHz analog to digital converter (ADC) and a 125 MHz digital to analog converter (DAC). However, there is no antenna matching, AGC, tuning or IF filtering. Seems like the Red Pitaya is more suited to some kind of electrical mechanical control. Now that I have bashed it as an SDR I will point out a very positive feature. The Red Pitaya has a Xilinx ZYNQ FPGA. Some of the other SDRs have a smaller FPGA that, with some effort, the user can implement radio digital signal processing. The Red Pitaya has a much larger FPGA that could possibly perform all the signal processing need to completely decode the received message – if it was a radio.

Quadrus SDR
Except for a much smaller FPGA, Quadrus SDR is similar to the Red Pataya. There are four channels of phase coherent sampling but no front end RF components. Most radio front end circuits provide frequency down converting, filtering and up to about 100 dB of gain to match the receive signal to the ADC dynamic range. Here, we have up to 30 dB gain going directly into the ADC input. Coupled with properly designed radio front end hardware this device could be a good platform for multiple input multiple output (MIMO) signal processing.

RDP-100
This is a 6U Compact-PCI form factor hardware platform that can be used for SDR. This hardware is quite large compared with the other products discussed here. The fact that a card this large only has a Virtex 5 FPGA and no radio hardware tells me it is probably not a good choice for an SDR. The Rad Pitaya will perform better for less money.

ThinkRF WSA5000
With a tuning range up to 27 GHz, this SDR is unique. The pricing starts at $3500, a bit outside the hobby category and more like professional test equipment. Comes with spectrum analysis software.
SignalHound BB60C
This has radio front end components however is it is designed for use as a spectrum analyzer and is not an SDR.

Video – New Test Success – Navy’s Naval Integrated Fire Control-Counter Air concept (NIFC-CA)

ATI teaches more than 50 courses on EW, Missile Systems and Radar Tracking. We thought this article would interest our students.

This test combines the F-35B EW system with the Aegis System in a new way.

https://news.usni.org/2016/09/13/video-successful-f-35-sm-6-live-fire-test-points-expansion-networked-naval-warfare

Using targeting information transmitted from the Marine Corps F-35B, the Navy’s Aegis test site at the White Sands Missile Range, New Mexico launched an SM-6 anti-air missile and struck a target representing an adversarial fighter.

F-35 sensors include the Active Electronically Scanned Array (AESA) radar capable of air-to-air operations, air-to-surface operations, and a broad spectrum of electronic warfare and intelligence, surveillance and reconnaissance missions.

The unmodified F-35 picked up the target with its own sensors and routed the track via the fighter’s Multifunction Advanced Data Link (MADL pronounced: MAHdel) to the Navy’s USS Desert Ship (LLS-1) test platform running the Baseline 9 Aegis Combat System. Lockheed and the Navy attached a MADL antenna to the combat system to receive the track information that fed the information to the SM-6.

Zumwalt Destroyer Moving Toward Commissioning

 

The Navy gave a first look inside the stealthy and futuristic Zumwalt destroyer on Friday during the ship’s first port stop at a Rhode Island naval station.

160908-N-CS971-005 NEWPORT, R.I. (Sept. 8, 2016) The guided-missile destroyer Pre-Commissioning Unit (PCU) Zumwalt (DDG 1000) arrives at Naval Station Newport, Rhode Island during its maiden voyage from Bath Iron Works Shipyard in Bath, Maine. The port visit marks Zumwalt's first stop before the ship ultimately sails to her new homeport of San Diego. During the transit, the ship is scheduled to take part in training operations, a commissioning ceremony in Baltimore and various additional port visits. Zumwalt is named for former Chief of Operations Elmo R. Zumwalt and is the first in a three-ship class of the Navy's newest, most technologically advanced multi-mission guided-missile destroyers. (U.S. Navy photo by Haley Nace/Released)

The 610-foot-long warship has an angular shape to minimize its radar signature and cost more than $4.4 billion. It’s the most expensive destroyer built for the Navy. It’s headed from Naval Station Newport to Baltimore, where it will be commissioned in October before going to its homeport in San Diego. It was built at Bath Iron Works in Maine.

It is on its way to its commissioning in Baltimore on Oct. 15. The USS Zumwalt is docked at Naval Station Newport on Thursday after its arrival from Maine. The first of three Zumwalt class destroyers, the Zumwalt is about 1½ times the size of the previous Arleigh Burke class destroyers but is manned by only 147 sailors, about half the size of a Burke crew.

Interestingly enough, we blogged about this as a “ship of the future” in 2014:

NAVY’s Stealth Ship of the future: Zumwalt

 

This link discuss the third Zumwalt ship. Navy consideration of scrapping third ship of Zumwalt-class destroyer to save money.

http://www.militaryaerospace.com/articles/2015/09/zumwalt-class-destroyer.html

 

 

The following was posted to USNA-AT-LARGE Yahoo group and was written by Roger Barnett, Professor Emeritus, Naval War College.

Visited Zumwalt yesterday–not USS Zumwalt yet.  (That happens on October 15 in Baltimore:

http://usszumwalt.org/commissioning-2016/

Local news write-up here:  https://dl.dropboxusercontent.com/u/122348/State%20of%20the%20art%20ship%20visits%20Naval%20Station%20Newport%20%7C%20Page%20One%20%7C%20newportri.com.pdf

Wore my USS Texas  (BB-35) shirt because I was interested in a comparison of that battleship and the new destroyer.  Here’s a bare-bones look at size, complement, and cost:

Zumwalt (2016)     USS Texas (1914)
Length                610ft              573ft
Beam                   81ft               95ft
Displacement     16,000T        27,000T
Complement       147                1,042
Cost                     ≈$4b              $11m in 1912 (≈$275m today)

•  Toured the ship with a group of 25.  Was onboard for about 30 minutes, toured forecastle–no ground tackle in view; bridge–3 watchstanders when ship is underway, (also three watchstanders in engineering, I was told)  very poor visibility from small windows, but large video screens above the windows, all the way around.  Not possible to position lookouts out in the elements.  External visibility must be minimal at night.  Then to Combat:  About 15 workstations in large room, about 20 feet high.  CO’s battlestation on centerline of space, 2/3ds of way back.  Large video screens all around.

•  Ship has complement of 147.  There is no such thing as a separate condition 3; ship is always at condition 3 when underway–owing to automation, no additional stations to fill.

•  No non-rated aboard. All enlisted are E-4 to E-9.  Enlisted live in 4-person compartments, each with its own head.  Officers–except CO, XO, Unit CDR, and Chief of Staff–and most senior CPO’s in 2-person staterooms, en suite.  Ship has about 60 heads (!), which are cleaned by occupants.  I did not ask who cleans CO’s and Unit CDR’s heads.

•  Weapons: 80 VLS launch cells located on the periphery of the ship–outside the lifelines, which are removed when the ship is underway–in the forward third of the ship.  Also two 155mm advanced gun systems in two mounts forward and two 30-mm gun systems that are for defense against small craft swarm tactics (https://news.usni.org/2014/08/05/navy-swaps-anti-swarm-boat-guns-ddg-1000s).  Can embark two MH-60 helos; can also carry drones, which would be embarked as a detachment with controllers, but not simultaneously with helos.  Can carry two RHIBs.  Ship had only one aboard as we saw when we visited the boat deck.  Tour guide said they were investigating loading V-22 Ospreys, but there was an issue with the exhausts damaging the nonskid on the flight deck.  (NFI)

•  Very large composite superstructure, housing SPY-radar system, must be vulnerable to attack with high velocity frag warheads.  SPY not yet installed.  Small navigation radars fore and aft are temporary until SPY system is installed while ship is in San Diego.

•  Ship’s firefighting suite uses fresh water.  Officer conducting tour said he did not know why, except that salt water was more conductive and more damaging to electronics than fresh water.  This was an eye-opener for me, who tends to believe that a fire aboard ship takes precedence to concerns about harming the electronic suite.  The mindset, however, is that the electronic system is life, and without it you will be sure to die, so it is always the top priority.  If someone knows more about this than I do, please enlighten!

•  Electric drive; gas turbine prime movers.

•  Other specs well laid out

https://en.wikipedia.org/wiki/Zumwalt-class_destroyer#cite_note-usni5aug14-8

•  Ship class at inception was for 32 ships, now the plan is to build 3.  Follows fairly closely the fate of the B-2 bomber.

 

How to Promote Your ATI Course in Social Media

How to Promote Your ATI Course in Social Media

LinkedIn for ATI Rocket Scientists

 

Did you know that for 52% of professionals and executives, their LinkedIn profile is the #1 or #2 search result when someone searches on their name?

For ATI instructors, that number is substantially lower – just 17%. One reason is that about 25% of ATI instructors do not have a LinkedIn profile. Others have done so little with their profile that it isn’t included in the first page of search results.

If you are not using your LinkedIn profile, you are missing a huge opportunity. When people google you, your LinkedIn profile is likely the first place they go to learn about you. You have little control over what other information might be available on the web about you. But you have complete control over your LinkedIn profile. You can use your profile to tell your story – to give people the exact information you want them to have about your expertise and accomplishments.

 

Why not take advantage of that to promote your company, your services, and your course?

Here are some simple ways to promote your course using LinkedIn…

On Your LinkedIn Profile

Let’s start by talking about how to include your course on your LinkedIn profile so it is visible anytime someone googles you or visits your profile.

1. Add your role as an instructor.

Let people know that this course is one of the ways you share your knowledge. You can include your role as an instructor in several places on your profile:

  • Experience – This is the equivalent of listing your role as a current job. (You can have more than one current job.) Use Applied Technology Institute as the employer. Make sure you drag and drop this role below your full-time position.
  • Summary – Your summary is like a cover letter for your profile – use it to give people an overview of who you are and what you do. You can mention the type of training you do, along with the name of your course.
  • Projects – The Projects section gives you an excellent way to share the course without giving it the same status as a full-time job.
  • Headline – Your Headline comes directly below your name, at the top of your profile. You could add “ATI Instructor” at the end of your current Headline.

Start with an introduction, such as “I teach an intensive course through the Applied Technology Institute on [course title]” and copy/paste the description from your course materials or the ATI website. You can add a link to the course description on the ATI website.

This example from Tom Logsdon’s profile, shows how you might phrase it:

 

Here are some other examples of instructors who include information about their courses on their LinkedIn profile:

  • Buddy Wellborn – His Headline says “Instructor at ATI” and Buddy includes details about the course in his Experience section.
  • D. Lee Fugal – Mentions the course in his Summary and Experience.
  • Jim Jenkins – Courses are included throughout Jim’s profile, including his Headline, Summary, Experience, Projects, and Courses.
  • 2. Link to your course page.

In the Contact Info section of your LinkedIn profile, you can link out to three websites. To add your course, go to Edit Profile, then click on Contact Info (just below your number of connections, next to a Rolodex card icon). Click on the pencil icon to the right of Websites to add a new site.

Choose the type of website you are adding. The best option is “Other:” as that allows you to insert your own name for the link. You have 35 characters – you can use a shortened version of your course title or simply “ATI Course.” Then copy/paste the link to the page about your course.

This example from Jim Jenkins’ profile shows how a customized link looks:

 

3. Upload course materials.

You can upload course materials to help people better understand the content you cover. You could include PowerPoint presentations (from this course or other training), course handouts (PDFs), videos or graphics. They can be added to your Summary, Experience or Project. You can see an example of an upload above, in Tom Logsdon’s profile.

4. Add skills related to your course.

LinkedIn allows you to include up to 50 skills on your profile. If your current list of skills doesn’t include the topics you cover in your course, you might want to add them.

Go to the Skills & Endorsements section on your Edit Profile page, then click on Add skill. Start typing and let LinkedIn auto-complete your topic. If your exact topic isn’t included in the suggestions, you can add it.

5. Ask students for recommendations.

Are you still in touch with former students who were particularly appreciative of the training you provided in your course? You might want to ask them for a recommendation that you can include on your profile. Here are some tips on asking for recommendations from LinkedIn expert Viveka Von Rosen.

6. Use an exciting background graphic.

You can add an image at the top of your profile – perhaps a photo of you teaching the course, a photo of your course materials, a graphic from your presentation, or simply some images related to your topic. You can see an example on Val Traver’s profile.

Go to Edit Profile, then run your mouse over the top of the page (just above your name). You will see the option to Edit Background. Click there and upload your image. The ideal size is 1400 pixels by 425. LinkedIn prefers a JPG, PNG or GIF. Of course, only upload an image that you have permission to use.

 

Share News about Your Course

You can also use LinkedIn to attract more attendees to your course every time you teach.

7. When a course date is scheduled, share the news as a status update.

This lets your connections know that you are teaching a course – it’s a great way to reach the people who are most likely to be interested and able to make referrals.

Go to your LinkedIn home page, and click on the box under your photo that says “Share an update.” Copy and paste the URL of the page on the ATI website that has the course description. Once the section below populates with the ATI Courses logo and the course description, delete the URL. Replace it with a comment such as:

“Looking forward to teaching my next course on [title] for @Applied Technology Institute on [date] at [location].”

Note that when you finish typing “@Applied Technology Institute” it will give you the option to click on the company name. When you do that ATI will know you are promoting the course, and will be deeply grateful!

When people comment on your update, it’s nice to like their comment or reply with a “Thank you!” message. Their comment shares the update with their network, so they are giving your course publicity.

If you want to start doing more with status updates, here are some good tips about what to share (and what not to share) from LinkedIn expert Kim Garst.

8. Share the news in LinkedIn Groups.

If you have joined any LinkedIn Groups in your areas of expertise, share the news there too.

Of course, in a Group you want to phrase the message a little differently. Instead of “Looking forward to teaching…” you might say “Registration is now open for…” or “For everyone interested in [topic], I’m teaching…”

You could also ask a thought-provoking question on one of the topics you cover. Here are some tips about how to start an interesting discussion in a LinkedIn Group.

9. Post again if you still have seats available.

If the course date is getting close and you are looking for more people to register, you should post again. The text below will work as a status update and in most LinkedIn Groups.

“We still have several seats open for my course on [title] on [date] at [location]. If you know of anyone who might be interested, could you please forward this? Thanks. ”

“We have had a few last-minute cancellations for my course on [title] on [date] at [location]. Know anyone who might be interested in attending?”

10. Blog about the topic of the course.

When you publish blog posts on LinkedIn using their publishing platform, you get even more exposure than with a status update:

  • The blog posts are pushed out to all your connections.
  • They stay visible on your LinkedIn profile, and
  • They are made available to Google and other search engines.

A blog post published on LinkedIn will rank higher than one posted elsewhere, because LinkedIn is such an authority site. So this can give your course considerable exposure.

You probably have written articles or have other content relevant to the course. Pick something that is 750-1500 words.

To publish it, go to your LinkedIn home page, and click on the link that says “Publish a post.” The interface is very simple – easier than using Microsoft Word. Include an image if you can. You probably have something in your training materials that will be perfect.

At the end of the post, add a sentence that says:

“To learn more, attend my course on [title].”

Link the title to the course description on the ATI website.

For more tips about blogging, you are welcome to join ProResource’s online training website. The How to Write Blog Posts for LinkedIn course is free.

Take the first step

The most important version of your bio in the digital world is your LinkedIn summary. If you only make one change as a result of reading this blog post, it should be to add a strong summary to your LinkedIn profile. Write the summary promoting yourself as an expert in your field, not as a job seeker. Here are some resources that can help:

Write the first draft of your profile in a word processing program to spell-check and ensure you are within the required character counts. Then copy/paste it into the appropriate sections of your LinkedIn profile. You will have a stronger profile that tells your story effectively with just an hour or two of work!

USNI News Video: What is Aegis Ashore?

Sam LaGrone – July 1, 2016 – USNI


In May, the U.S. Navy and the Missile Defense Agency activated a maritime radar about 200 miles away from any saltwater.

The Lockheed Martin SPY-1D radar is installed in Deveselu, Romania and is the heart of the Aegis Ashore missile defense system built on systems found on the Navy’s guided missile cruisers and destroyers.

 

“To put it simply, our new missile defense architecture in Europe will provide stronger, smarter, and swifter defenses of American forces and America’s Allies. It is more comprehensive than the previous program; it deploys capabilities that are proven and cost-effective; and it sustains and builds upon our commitment to protect the U.S. homeland against long-range ballistic missile threats; and it ensures and enhances the protection of all our NATO Allies,” President Obama said in 2009.

Why engineers are better than everyone else

Applied Technology Institute (ATI Courses) offers a variety of courses on space, communications, defense, sonar, radar, and signal processing. We believe the news summarized below would be of interest to our readers.

February 16 marked the beginning of National Engineers week in the U.S.  EDN celebrated engineers with six reasons Why engineers are better than everyone else!  The tongue-in-cheek piece elaborated on these engineering qualities:

  • Team work, not cut-throat competition
  • You’re boring at parties
  • Start-ups don’t happen without you
  • Your degree is worth more than the paper it’s printed on
  • Go ahead, argue
  • Others make problems, engineers find solutions.

For the logic, see the entire article (Why engineers are better than everyone else) by Suzanne Deffree, February 20, 2014.

 

Fun post on Deflategate with STEM applications

This is a fun article on measuring the bounce of under-and over- inflated footballs, basketballs and soccer balls. It can attract interest in STEM and applying the scientific method.

“The purpose of this article (Bouncing Back From “Deflategate” Bouncing Back From “Deflategate”) is to bring “Deflategate and the Physics of a Bouncing Ball” into the laboratory activities of high school and undergraduate introductory physics courses in a way that does not involve the ideal gas law.”

New Horizons – This was almost a disaster, but was saved by knowledgeable scientists.

The people in the Mission Operations Center — “the MOC” — had been tracking NASA’s New Horizons spacecraft for 9½ years as it journeyed the breadth of the solar system. It was just 10 days away from the dwarf planet Pluto when, at 1:55 p.m. on July 4, it vanished.

The disappearance of the spacecraft challenged the New Horizons team to perform at its highest level and under the greatest of deadline pressures. They did work efficiently and saved the mission. We all wish the New Horizons team the best as they approach the busiest time of the fly-by encounter. I have known and respected many of the engineers and scientist for more than 20 years and am happy to praise their skills.

The nature of the New Horizons mission did not permit any wiggle room, any delays, any do-overs, because it was a flyby. The spacecraft had one shot at Pluto, tightly scheduled: When it vanished, New Horizons was going about 32,000 miles per hour and on track to make its closest pass to Pluto, about 7,800 miles, at precisely 7:49 a.m. July 14.

But as the New Horizons team gathered in the control room on July 4, no one knew whether their spacecraft was still alive.

 

Because New Horizons is so far away, it takes 4 1/2 hours for a one-way message between the spacecraft and the MOC. That means whatever happened to New Horizons on July 4 had actually happened 4 1/2 hours before the people in Mission Operations knew about it.

 

The team figured out what had gone wrong. The spacecraft’s main computer had been compressing new scientific data for downloading much later. At the same time, it was supposed to execute some previously uploaded commands. It got overloaded; the spacecraft has an “autonomy” system that can decide what to do if something’s not quite right. That system decided to switch from the main to the backup computer and go into safe mode.
