I appreciate everyone who were helping me troubleshoot my uBITX V6 with low audio before Christmas. I've since been gone spending time with the grand-kiddies. Now going to get back to this.
I compiled all the previous dialog and suggestions into one WORD document attached. I'll be going back going over all that was suggested. Checking voltages, resistances, etc.
I noticed in one suggestion - "Before you continue trying to align it, the first thing to do is to connect an external audio amplifier to TP20 and ground and see whether it makes a difference and continue using it to see whether the fault reappears. If it works and continues to work then the fault could be in the audio chain."
This morning I put my external audio amplifier at TP20. Nothing, no audio from the external amp. And as I mentioned earlier, I do hear the sidetone in the speaker, and it is LOUD! Really loud, cannot use headphones on CW, hurt these old ears.
Also this morning, I used the radio to check into the Noon-Time-Net with both CW and SSB. No problems, good reports. So we know TX is apparently working OK. Frequency is a bit off but I can get that later if and when the audio issue is solved.
So, in light of not having any audio from TP20 into the external amp, does that tell you something on where to go next? I'm about to drag out the O'Scope, signal tracer, RF generator, blow up the schematic, do some serious studying. Got to clean off this workbench. Thank you all. Take care...
