full break in HW 16
Brings back memory's of when I was first interested in Ham radio. The description of that radio/transmitter with dual conversion and crystal filters was something that made me want that rig. I did not become a Ham until much later when I hooked up a down converter to a Radio Shack general coverage shortwave receiver and started following a group of Hams, on 2 meters (I had to slope detect), that would meet after work at a near by Denny's restaurant. I became interested in joining in, they were frequently discussing interesting radio/technical things, so I contacted (by mail) one of the Hams, he lent me some more gear, I studied, got my tech license, and could join in of the work commute and Denny's.
Back to full break in mode. Tubes are still popular in the audio circles. Wonder if it would be possible (or valid) to create a stand alone tube RF pre-amplifier for receivers that would be bullet proof against (at least in terms of not burning out) being attached to a coax line while a transmitter is powered up on the same coax. This could be great for near by lightning strikes, too.?
Then you could put a tee connector in your coax to directly connect to the vacuum tube pre-amp.
To some extent this tube pre-amp may be sold more on the?nostalgia of the gold old tube days. And unfortunately some marketers may start selling it on the claim that if gives your radio the much improved "tube" sound quality. But it might be a cool idea. Especially if the tube sticks?prominently out of the top of the box, so you can see the red filament glow, and maybe a ring of blue LEDs at the base to add to the cool tube effect.
Joking aside, it may possible there could be a place for a vacuum tube in RF front ends.?
