This is the first base station in the line of Galaxy CB radios. In these days of converted 10-meter radios, companies like Cobra, Midland and Uniden seem to be trimming their CB radio lines. Cobra with the elimination of their base station radios. Midland back in the hay days was one of the first manufacturers…
Sam Lewis of RF Limited/Clear Channel Corporation contributed some background info on the radio players in the 10 Meter radio market they associated or partnered with going back to 1969. The story is interesting and lends insight to how the 10 Meter radios evolved. Many AR 3300 and AR 3500 owners probably have no idea…
A Little Background On or about February 24, 200, Mr. Alan Dixon, N3HOE, filed a petition with the FCC to remove the 250km (155.3 mi.) distance limit for contacts on CB radio. It received strong opposition from both the ARRL (Amateur Radio Relay League) and the NAB. (National Association of Broadcasters) The ARRL’s comments taken…
The most common wiring available is the 4-pin Cobra/Galaxy/Uniden, although it can be wired to any radio on the market today. I’ve even tried one on a Tram D201 tube rig. It sounded outstanding. I’ve also used one with a Magnum Delta Force, setting the mic and the radio internal turbo echo to different settings…
Lightning is one of Nature’s most destructive forces. It has the power of a good-sized explosive and cannot be avoided if you’re connected to antennas that are high and in the clear. And it’s not just lightning. On a recent evening, our 160 Meter dipole (260-foot wire span) strung between towers at 180′ here at…

Inside The Galaxy DX 2547 AM/SSB CB Base Station Radio The first thing I noticed after removing the top and bottom covers was the mobile chassis mounted in the base chassis. At first I was disappointed thinking this was a cheaply made base radio. What they have done was use the aluminum chassis of their…
Adding the MD-4 to radios with internal analog meters is more difficult than the Magnum 257 and 357DX. Although the following amplifier circuit works with the Magnum 257/357dx radios, its not necessary unless you desire the bar graph meter to also work. Adding the MD-4 external meter to the radios internal meter signal adds a…
Adding the MD-4 to the Magnum 357DX is simple if you don’t want the LCD meter to read any signal. The MD-4 external meter measures current and draws the voltage down to the LCD meter, thus the LCD won’t read once the MD-4 meter is connected to the same signal feeding the internal meter. Remember,…
As mentioned in this month’s review of the Magnum 357DX, there are different conversions that can be performed on this radio. Two will be covered in this article. Remember to always disconnect electronic equipment from the power source before doing any modifications. The most common and simplest conversion is cutting the diode lead on the…
