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

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

Could be?

Plate blocking cap? It's a TDK 1700pf 20kv.

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

*** Indeed. Somebody told me about a "speech processor" that he cobbled together out of commercial/professional audio equipment. He basically chopped the speech spectrum into several sub-bands.

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,

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

Hey, folks, I haven't forgotten you! I went to the doctor today for my foot problems and he has told me to stay off my feet for today and gradually going back to light activity tomorrow. Plantar

Update: Checked drivers, no leakage.. How ever CR1402 is done and now identifies it self as a resistor, however I assume CR1402 has little to do with TX and only RX/Calibrator signal? Any ways waiting

Why do the mounting fins matter? The more common lockwasher and nut mount seems to be an OK replacement. Thanks, KD4E

Any. other symptoms? ?So far, could be a relay issue.

Has anyone done this? Using the push button switch is so clunky to use! If you've done it, just what was involved? 73, Dave KD5FX

Ron Any update on your problem? I am having? a similar problem with no grid current. Jake

Well, the SP75 sounded OK. The pre-clipping compressor stage was quite good by itself (0 dB clipping selected). Some LF cut in evidence when it's in-circuit, which the locals commented upon, but DX

Yeah, I think I would go with that... "jerry-KF6VB via groups.io" <jerry@...> wrote: -- 73 -Jim NU0C

*** I just had an interesting thought. I bet I could do an RF speech processor in software. I have a few Teensy 4.0 processor sticks - they have a very powerful audio library - with oscillators,

One of mine had a leaky driver transistor that caused all sorts of weird stuff. CAREFULLY check the voltage on the base of the drivers. It should be zero in RX. I would not measure directly at the

Selectivity of the R-4C crystal filters is better than the R-4B’s 50 kHz L/C filters. Sensitivity very similar, maybe slightly better for the C-Line. Rob, NC0B

Sometime during the production of the TR7 the 470K in series with pin 4 was added to provide the high level input. The three rigs I have all have it. It was also added by the service department to
