A friend of mine recently gave me a pair of DMR HTs. I am not excited in any way by what I call 2 Meter CB (or in this case 70 cm CB) but he thought I should have them for ARES. For me the audio falls

Ok, so after buying new tubes and ruling, it is not the tubes that was exspenseve. I poked around the bias and discovered that I had no bias voltage. Tracing back the bias to the soft start board. I

As a foreign language learner, fidelity is important to me. I need those sibilants and fricatives! I was disappointed with DMR; It had promise: the ability to pop up in some foreign country and

A few decades ago I used one of these on my T4XC. ?Adjusted properly, it improved "punch" for poor band conditions while at the same time not adding distortion like some processors do.

Richard mentioned some interesting points. ?If you want to have some fun, tune around on 75M and listen to the groups that have high end radios (e.g. ?Flex, Elecraft, etc.) with Behringer (sp?)

Reports on trial of 4B twins say audio seems clipped and missing lows. ?D104 works fine on my Swann and I tried my Sure 444 with the same result. High pitched and no lows. The result is same on 80,
