Re: SX-100 phono input
I think may stumbled on to the issue. Faulty volume control. Injecting a 1000khz signal at the antenna. Using internal modulation from the IG102. Messing with the volume control, I suddenly got the

Listing electronic items (exotic tubes)
For Bill, system manager, Hi Bill, A ham friend, now SK, left me some tubes, cables, antenna switches, etc., is it okay to list them on the forum? Most tubes are exotic or high-power ones I don¡¯t

Re: SX-100 phono input
What instruments do you have? I think you said in another post on this thread that you have an oscillator. I think I would start by putting a tone into the phono jack and setting the selector switch

Re: SX-100 phono input
Determining the correct voltages on output tube V9 6K6 doesn¡¯t tell you everything about why there possibly is no audio but it is a place to start trouble shooting. However I am not sure if that

Re: SX-100 phono input
Yes it is a selection on the front of the radio for phono input. I am checking voltages first but just had that idea this week looking at the schematic. And it does feed directly in. I can also take

Re: SX-100 phono input
To add to this, just to make sure, the phono input is just a low level audio input to the audio amplifier. It does not need to be modulated. Its a suitable place to inject a low level audio tone. I

Re: SX-100 phono input
First find out if you even have proper voltages on the pins of the 6K6! If the OT primary is open¡ nearly zero volts on the plate, pin 3. If no screen voltage on pin 4¡ no audio. If the 6K6 is not

SX-100 phono input
Question for the group.... Will be working on the SX100 again this weekend. I am not getting any sound from the speaker. As stated before, I tap across the 6k6 pin and get some static on the speaker.

Re: SR2000 cal osc
12.47 volts AC on that tube. It seems to be working. Just not strong on higher bands. Maybe it's because it's out of case? About s6 on 80 meters.

Re: SR2000 cal osc
Just to be sure, measure the ac voltage on the filament of V11. Check CR10 and the cap that feeds it. Check V11B pins 1 and 8 against the voltage chart in the manual. Walt Cates, WD0GOF
