They generate lots of PIM. Do a search for PIM and read all the info there. In high power digital modulation schemes, antennas and connectors are now rated for PIM. TDMA modulation can generate sever
That's ok... My 1KV load capacitor will arc (acting just like a spark gap....) across before the 3 KV padders will. BTW I never have had my 1KV loading cap arc. EVER! And I contest on RTTY with it. 7
I cant believe my radio said that!!! LOL! 73 Jim W7RY the argument used by all the authorities is this: At an open circuit the forward voltage is Vf. Because it is reflected as VR and is the same vol
Denis.... I've used both the WD7S triode board (in my current 8877 amplifier) and the G3SEK board in my 3CX800 amplifier. I would use the G3SEK board over the WD7S board but Ian's board doesn't have
Whatever you can find. 1000Pf is fine. You can always add some capacitance with a disk cap is needed. 73 Jim W7RY 18/12/2013 13:16 I have built an amplifier change over relay set housed in a die cast

I simply use DC instead of RF to check the relays themselves. There is info on the WD7S web site for that. For measuring an actual radios relay speed, I use RF from the transmitter and DC for the amp
Agreed Ward! When you see an old piece of equipment, visualize it as an amplifier cabinet. How easy is it to make a new front panel? New back panel? I've even bought old medical equipment for an ampl
