Hi All, I finally found some time to try fixing this issue. I moved the LED and photoresistor out of the board and over the AUDIO socket. Now there is no long cables connecting the photoresistor to th

Don Peculiar. Not likely you have a 3.8 kHz clock. It looks a bit wide, maybe it's a switching power supply emission. It's coming from something. Curt

I did and while I don't know exactly what they should be (and too lazy atm to calculate) but all voltages around Q10/11/12 looked reasonable for npn transistors - good idea t check the Q30 etc group -

Brian, Evan has explained the slider function if you have a nextion display. Using the memory manager you can also do the same thing. There is a selection for the 1st IF (45mhz) calibration. Evan show

Good luck. Electric blankets, LED drivers, Compact Fluorescent Lamps, and lots of electronic devices using switching power supplies are polluting our bands. I am in Florida for the winter. When I get

Gary, Is it possible to remove the Raduino and display from the case and connect to the USB port on your computer without the mainboard? The Raduino should powerup and the display should show the norm

Yep, I noticed that on the response curve. Jack, W8TEE

No worries, at least I have some sort of audio now and have tuned in a few 20m conversations and know the RX side of the radio works at least. I'll keep studying the schematics and experimenting and e

Hah! I forgot to include the relay. Also I meant to say "source and gate" but wrote "source and drain"! So yes, I guess I shoulda stayed at Holiday In Express last night!
