New Palstar HF-AUTO Automatic Antenna Tuner. New HF-AUTO will have some of the following specs that supercedes the already complex design of the AT-AUTO with new and innovative design improvements. The HF-AUTO will function fast and flawlessly with ANY transmitter without plodding through menus and cables, that in most cases will not work with other accessories. Specifications: – 1 Watt to 2500 watts….average, peak, and peak-hold – Load into a 10:1 SWR from 1.8 to 54 Mhz – NO CI-V cables required – Tunes on SSB – Digital Display…no analog metering – Remotable… up to 400′!

Yaesu FT-7900R Face Mounted

The cut-and-folded portion of the headliner becomes the primary mounting surface, which secures the radio surprisingly well under the compression of the supplied mounting bolts. The supplied double-sided foam tape comes in handy for test-fitting and holding the face steady while you bolt it in. A small nail comes in handy for making pilot holes for the bolts.

An ample amount of hot-glue supports the front end of the face/mount and keeps the assemly at the correct angle. Placing the headliner at an angle at the corner of a table, then resting the front on the radio’s face itself provides enough weight to hold everything in place while the glue hardens. Care should be taken not to drip hot glue down through so it is visible from the other side, though it does clean up easy if you do.

Ham Radio’s Technical Culture (Inside Technology)

Decades before the Internet, ham radio provided instantaneous, global, person-to-person communication. Hundreds of thousands of amateur radio operators–a predominantly male, middle- and upper-class group known as “hams”–built and operated two-way radios for recreation in mid twentieth century America. In Ham Radio’s Technical Culture, Kristen Haring examines why so many men adopted the technical hobby of ham r

This is using an RDP program on the iphone to remotely control the computer in the shack which is running Ham Radio Deluxe 5. In my case the shack is in a building not connected to the house, so this is a really handy way to work digital modes such as PSK or RTTY anywhere in the house via wifi to the shack laptop. The combination of pskreporter displaying perfectly on the iphone browser, and using hrd remotely makes PSK easy to work from any chair in the house.

Our amateur radio enthusiast buys another ham radio instead of attending to the needs of his family. His wife is not pleased.

No offense to anyone intended, even if you are guilty of this. Enjoy.

This is my third visit as a guest ham radio operator aboard the USS Pampanito that is docked at Pier 45 at Fisherman’s Wharf in San Francisco. It is great to be in a historic submarine and to give ham radio operators a contact from a very unique ham radio station. USS Pampanito (SS-383) is a World War II Balao class Fleet submarine museum and memorial that is open for visitors daily at San Francisco’s Fisherman’s Wharf. Pampanito made six patrols in the Pacific during World War II during which she sank six Japanese ships and damaged four others. Operated by the Maritime Park Association, Pampanito hosts approximately 110000 visitors a year and is one of the most popular historic vessels in the country. In addition to day time visitors, over 15000 kids a year participate in Pampanito’s educational day and overnight programs. Pampanito is a National Historic Landmark. The Pampanito is being restored to a specific point in time, late summer, 1945, to represent the height of WW II submarine development. The Maritime Park Association has scoured the country in search of missing equipment and spare parts. Almost all of the missing items have now been replaced and much of the equipment on board has been restored to operation. For more information, a virtual tour and a podcast please go to the USS Pampanito homepage www.maritime.org

This is a video of my Yaesu FT-857D and ATAS-120A installed on a 2006 New Beetle TDI. It’s purpose is to show you some of the capabilities of the Yaesu FT-857D and ATAS-120A Active Tuning Antenna System also made by Yaesu. I have installed the radio using the Separation Kit from Yaesu for FT-857D and it has been working like no other. I am so pleased with this system that I may get a second set for field operations such as portable or during when I am hiking. If you have any question about my setup, or if you’re having problem with the ATAS, drop me a note, and I will do my best to give you some pointers. I spent many weeks perfecting the installation and right now, I have zero issues with ATAS. There are lots of information out there on the Internet but the important ones I found by experimenting. If you’re on the fence about this setup, don’t because it works really well. RF grounding braids are very important – I think they are the most important than any other types of grouding for the ATAS. Fortunately, I have a unibody vehicle which makes grouding a bit easier. However, if you have a body on frame vehicle like SUV or pickup truck, I would really ground multiple points underneath the vehicle. 73 from Pete KC2ZXL

This video presents an inexpensive approach to detecting and recording directed energy weapon attacks using relatively inexpensive equipment. The modifications to the digital voice recorder depicted here required a basic understanding of circuitry and soldering techniques. The total cost of materials is under 200 dollars and depended primarily on the cost of the digital voice recorder. Be sure to buy a digital voice recorder that allows you to upload the recordings into your computer, and one that has two microphones if you choose to do the modifications. WARNING – this will not stop directed energy attacks, but will provide reasonably credible evidence that you and your voice recorder are being exposed to pulses of radio frequency radiation of sufficient strength to compromise the audio circuitry in the voice recorder. The following links were presented in the video: www.scribd.com www.scribd.com The following link provides an example of how digital voice recorders could be used to provide evidence of directed energy attacks: www.scribd.com
