Galaxy 2527 CB Base Station Performance Review

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 […]

The Anttron Story

n 1961 Frank J. Kukura Jr. and his father formed Kem-tron Industries specializing in manufacturing power supplies, frequency counters, Interceptor 100, Thunderbolt 305, RoadRunner 150 and many other products including antenna electronics like coaxial switch boxes, Ham and CB Base antennas, and fiberglass mobile whips.

Cobra XL 450 Linear Amplifier From Mexico

This is the other unit that my customer brought in for test. The heatsink and front panel layout looks very familiar. It is a copy of the old Palomar Magnum linear amplifier. The Palomar folks no longer use the Palomar name or produce linear amplifiers since they were busted many years ago. They managed to […]

The RCI 2950DX is capable of covering 24.0000 MHz to 32.0000 MHz with the addition of a small circuit board provided by an undisclosed third party.

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 mobile CB radio and designed a base chassis that accepts […]

CB World Informer December 1996 Issue

The Midland 79-290 is the smallest sideband mobile available today. It measures only 2″ high by 6.25″ wide by 7″ deep. The small size combined with the detachable face makes it possible to safely mount it permanently in many vehicles. This is a new generation of CB radio designed and manufactured in Korea. Instead of […]

Follow-Up Of The Magnum Maverick A24 Radio

Back in the August issue I did an article on the new Magnum Maverick A34 10-meter radio. As mention in that article the radio submitted for review was a pre-production unit. Finally Magnum received 20 production radios and I was able to convince them to send one in. This time it arrived complete in a very […]

Review: RCI 2950DX Dual Band Amateur Radio

The RCI 2950 has been around for many years. The first radio of this type from Ranger Communications was the RCI 2900. The 2900 radio was a CPU type radio with an analog S/RF meter. Comparing the 2900 to the 2950, the meter was the only redeeming quality of the 2900. The 2900 radio was […]

Astatic’s Final Edition D-104 Silver Eagle

The definition of astatic that best suits the D-104 line of microphones is the one immediately above: having no particular directional characteristics. For years this mic dubbed the “lollypop” has been the most sensitive microphone known in the communications field. They have the capability of picking up everything in a room and more. I remember […]

RCI 6900F TB ALC Mod, Tune-Up, And PCB Adjustment Locations

The ALC modification requires the removal of surface mount parts and the addition of conventional through-hole type parts. When removing these components, take extra care not to overheat the circuit board. The traces will lift quite easily. When installing standard components, due to their larger size, it’s best to solder them to the trace where […]
