Is this an example of what is being discussed? http://www.fmamtv.com/products/Radio/BE%20AM10A.html That is becoming common practice. Modular transmitters. Just plug in the modules you want to get th
In the cobwebs of my memory I have a vague notion that the Transworld amp is associated with the Metron amp - is that correct? I have the Metron PDF. David KD4E I'm sure that somewhere I have the use
I don't get where the notion comes from that commercialization vs home brewing is something new to Ham radio. For at least 75 years commercial & military surplus gear have been a common part of our h
Re your "The FCC needs to catch up with noise floor challenges & modern technology." Be careful what you wish for here because if the FCC were to address these challenges and mandate rules for minimu

I built steps to a pool deck that were crooked but appeared sturdy ... they even lasted until a few months after the pool supports rusted-out ... then started to fall apart. Fortunately they didn't f
Storytime continues ... When I worked in a Heathkit store the policy was that a newbie had to buy and build a simple kit, then bring it in for inspection. IF they showed evidence of competence to sol
Why Facebook rather than the more neutral groups.io? I dumped my FB account years ago when it was first becoming the place to broadcast & leer at social dysfunction. Just asking ... 73, YMMV, IMHO ..

He was speaking in shorthand. Of course the radio is the "source" of the RF. Presuming that the coax is properly connected to the radio, the radio is properly grounded, and the antenna is resonant th
Paul, One small quibble - modern homes are vastly better insulated and heating systems are vastly more efficient - thus the cost to heat and cool - per sq ft - has been vastly reduced. And that is my
