The Quansheng UV-K5 has rapidly developed a reputation at the most "hackable" radio on the market today. There are many firmware variants available produced by the ham community, and more seem to come every week. Now, a daughterboard is available that opens up the radio for full HF/MW/SW/LW...

Retevis recently contacted me and asked if I would review their new Ailunce HA1G GMRS handheld radio. Of course, I can't turn down an opportunity to play with a new radio! Here's a deep dive into this new radio, highlighting the major features. The first thing to know is that the HA1G is dust...

This past weekend I went to the Petersen Automotive Museum in Los Angeles to check out some cool cars. To my surprise, they had a new display of the early evolution of car communication technologies and one of the units shown was this Realistic CB-FONE 23 in pristine condition. Check it out!

Here's an art piece I saw recently at the Nevada Museum of Art in Reno. This is called "Signal" by Elisheva Biernoff. The art piece is about the size of a postcard or old Polaroid. Read the description about her work, and you'll see that this is actually a painting of a photograph. The work is...

I am activating the Pennzoil 400 NASCAR race at Las Vegas Motor Speedway from 3/1/24-3/3/24! I will be camping in my RV on the infield backstretch the entire weekend and will be setting up an HF station powered by an Elecraft KX3 and KXPA100. i mainly plan to operate phone on 10-40 meters; as...

Racing on the Air is intended to be a fun way to operate ham radio at any type of racing event. Any type of formal racing event may be activated by any licensed ham, anywhere in the world. This is a fun, informal activity meant to promote ham radio and give new opportunities to make contacts at...

The K9KAO 440 Mhz repeater sits atop Sunset Peak in Southern California at 5200 feet, providing terrific coverage to the greater Los Angeles area. This last weekend, three of us took the trip up the mountain to do some much needed maintenance, including replacing the Motorola Quantar power...

One of the reasons I prefer the Android platform for mobile devices over Apple is the availability of creative apps for the amateur radio community. Many are available as open source, published on GitHub. FT8CN is a recently published app that allows you to use your phone or tablet as the...

This past weekend I visited the Nevada Museum of Art in Reno, NV. One of the galleries was sculptures by a guy named Cannupa Hanska Luger. I was surprised at the subject matter of this piece called The Keep, so I took a photo and copied the text to share. It's three stories tall. The Keep...

I've owned the Elecraft K4D for a while now. It's a wonderful rig. However, I am deeply disappointed in the NR capabilities on SSB and several have brought this up on the various Elecraft forums. Wayne N6KR, one of the Principals of Elecraft has commented that they intend to improve it by...

Everyone knows about SOTA and POTA. When I travel to small, out of the way locations, I like to stop by the local cemetary to learn something about the history of the area...it's fascinating to me what you can learn by reading some of the tombstones coupled with info available on the internet...

I go to NASCAR races every year. During the season, I even go to the local Saturday night NASCAR sanctioned races here at Irwindale Speedway. I've used an old Radio shack racing-style headset for years that I wired up for a Kenwood, Baofeng, etc. radio to use as a race scanner. This year I...

For the last couple of months, I have been extensively using a pre-release model of the Retevis RA89 10 watt VHF/UHF handheld radio. Now that the radio is fully released to market, I figured it was time to write a review. The RA89 is marketed as an IP68 rated rugged radio. The IP68 rating...

This is cross posted from the Elecraft reflector. The video is so impressive and informative that I wanted to make others aware of the project. See below and enjoy! ------------- I translated some antenna theory into computer graphics. I modeled the electric field for a 1/4 wave dipole, a...

Retevis send me their new RA89 VHF/UHF 10 watt handheld which is IP68 rated to test out. Being near the Pacific Ocean, I promised them a good salt water test. I don't think they had THIS in mind :cool:. More on this new radio coming soon...

Retevis recently contacted me to review their RT95 VHF/UHF 25 watt mobile radio. Of course, I'm always up for playing with a new (to me) radio, so I couldn't wait to get my hands on it. Here are my initial thoughts after using it for a few weeks. Overview First, this mobile radio really is...

The Baofeng UV-5RA VHF/UHF handheld is probably one of the most prolific radios in the amateur community. The ham community generally "knows" that these radios are considered dirty, but I'm not sure how many people have actually seen spectrum analyzer results. Well, here you go: Here are the...

A few weeks ago I posted a basic review of the TIDRADIO TD-H8 VHF/UHF handheld radio. Today I was able to measure the radio on my TinySA Ultra Spec Analyzer to see how clean this little radio is, especially since it has been approved for GMRS use. Here is the first plot transmitting on 146.52...

Like everyone, I'm shopping more on Amazon than anywhere else. I thought this thread might be useful for WorldwideDX forum members to share their finds on Amazon that others might find interesting. I just bought the TinySA Ultra spectrum analyzer. The regular TinySA cost less, but it didn't...

I recently installed a W6LVP Amplified Magnetic Loop RX Antenna on my roof on a small antenna rotor. One of the most useful benefits of adding an antenna such as this to your regular HF TX/RX antenna is that you can use it to null out unwanted signals. If you use it in conjunction with a phasing...
