MORE heat than a similar model 50w transmitter running 50w. This usually is
because of the additional transistors for the 100w model

I have acquired a Diamond X-500 which claims 8.3 dB on 144-148 MHz

making the gain claims ridiculous.. My guess is it's rated in dBi,
therefore, the claim may be a little closer to realistic.. 5

The best thing you can do it use real repeater equipment like a Motorola Micor
or GE Mastr II. Trying to make that Icom equipment work is going to be a
