My QMX luck is not too much better on this build than the last one. Well at least this one boots up and it actually transmits great. Got good RBN report. Receive is another story. When I first completed it, I was getting really loud noise from speaker and S-meter shows strong signal that fluctuates with Dummy load attached.?

Here is what I have done so far. I checked T401 by pulling it out and verifying I didn't have anything crossed. I didn't.
I replaced the PCM1804 although that was with the one on the other one that the processor failed so not 100% certain it is good but should be.
9K ohms for VDD and about 50K ohms for VCC to ground.
I have attached my hardware test results for 20M as most are about the same for all bands with the areas of concern. The only other two are ADC I Q test as the displays are different but then again similar and RF Sweep.

Any other troubleshooting suggestions would be greatly appreciated. I do have a scope, signal gen and a TinySA if any of those can aid.
