Re: Drake TR7, TX issue any ideas?

7077 update.
Thanks to Lawrence Coblenz. I have confirmed that the transformer is original but the capacitors are not. The transformer was glued to the top of the weight bar in the bottom of the base. I¡¯ll be

Re: TR4310 HF Transceiver

Yesss.. Jerry, I talked to you abut a Teensy speech processor after hearing about your excellent work on your KWM-2 CW mod. I just ordered a Teensy 4.0! This should be a fun new project after years of

Re: Warning on the 7077 (and any plastic Astatic mic)
For clarification, I believe that the head was glued to the base at the factory and the screw held it in place. If any of you have a 7077 that¡¯s partially disassembled, please let me know if this is

Warning on the 7077 (and any plastic Astatic mic)
As I grind my way through figuring what is wrong with this mic and how to repair it, I came upon an "O Cr@p!" moment when trying to disassemble it. You see, the wiring that came up through the

Re: TR-4C change the NB switch to do RF output?
Of course, most of this has been rendered obsolete by cheap power meters. I have two in-line with my Icom and Drake stuff by virtue of my C-4 and a built-in meter in my Nye Viking tuner. Surprisingly,

Re: TR-4C change the NB switch to do RF output?
I am not sure if you can do it on a C line but on my T-4X I was able to remove the spring so I could leave the switch in either position.? YES, original IS really clunky! 73, Gary WB6OGD
