Other than putting another hole in the faceplate, I don't think it would be a bad idea to use encoders w/o the push button switch. The reason is because some encoders have a stiff switch, which

What is the voltage on the base of Q1? What signal source are you using when you see no voltage output? Are you measuring at the junction of C3, R3, the cathode of D2, and the gate of Q2 to ground?

Spoiler alert! I mean that if not staged, she would soon be nursing some nasty 3rd degree burns. Of course, I've never done anything like that. ;-) Jerry

Good day, Raj. A DC chart would be great. What I have for diagnostics besides a few good DVM's are a dual-trace oscilloscope, an audio signal tracer, a single tone source, and another HF radio. Back

Outstanding. Looking forward to it. Thanks. -Ted

I’ve got several BITX varieties and I’ve put standalone pushbutton switches on every one. It’s great to be able to just push the button instead of anchoring my BITX with one hand and pushing

Hi Curt, I have tried a number of the AGC circuits floating around out there. They all seem to work, but do not handle large (>1000 microvolts) signals. Out of frustration, I have developed an AGC

Hi, Wayne. My apologies inasmuch as the hyperlink didn't embed correctly. This was what I used, though not ideal -

Don reply gratefully appreciated. base is biased at 0.67 volts, and collector is at 5.07 volts as the raduino supply. so this looks okay in terms of biasing the transistor. I have the rig

I'm just sorry to hear that it isn't working for you. From your description it all seems correct. It would be nice if there was some substantial signal that you could tune to, something steady and

Curt, Just to make sure, I opened up my uBIITX and checked voltages. With a 50 uV (S9, -73 dBm) there was about 1 to 2 millivolts RMS on the top of my volume control. But with 1,000 uV (about S9+27,

Don Thanks for wealth of info. Possibly with low solar flux it dawned on me that maybe signals are down a bit. I can see what my ft950 reads for largest signals. I have a fcc2 dds that has audio
