Hey Tom,
I've replaced the DAC and ADC and all surrounding components to no avail.? If there is a problem with the build, it's somewhere I can't get to (under a connector or something, I think unlikely).? The ADC and DACs are working, I can inject a signal into to RF IN on MAIN and I see it on the spectrum display and hear an output. ? I'm going to try to rebuild MAIN, need to find a board for sale.? I also have this pulsating noise problem on 20M that is not there when I turn the rig on (default to last freq selected) but appears when I switch bands and then come back to 20M.? The pulsating corresponds with LED 13 (SCLK to display) and with the spectrum update rate.? That SCLK also shows up on my power lines (100-200mv).? I'm running 50.2, I really believed there is a SW thing in there too but I'm just starting to look at it.? The filter adjustment stops working when I return from the menus too.? Same thing happens with 50.0.? Right in the middle of tax season!
So my next step is to try the latest SW version and mess around a little with some to the constants, make sure my config is good and monitor some things to see what might be changing when I change the state of the machine.? Rebuilding MAIN is on the to do list too.? This all happens when the box is full up and when only running MAIN (no display either).
I'll put out status as things develop.
Good luck.

Re: LPF-Control PCB TX Logic at U3 & U7
When TX_BPF_SEL is LOW, then RF2 is selected on U3 and U7 (BPF is bypassed for the TX path). When TX_BPF_SEL is HIGH, then RF1 is selected and the BPF is placed in the path.

According to the data sheet this is correct, selecting the BPF for transmit sets TX_BPF_SEL high resulting in a high on pin 6 of U3 which in turn connects RFC to RF1 which is the BPF connector. So no should not connect to RF2.

Re: LPF-Control PCB TX Logic at U3 & U7
I have checked the wiring,but still can't find the problem.? Everything is working on the T41 except U3? on the LPF-Control never puts the RF on RF2, (P3).? The logic of TX_BPF_SEL is putting a high on pin 6 of U3 and low
on pin 4.? According to the truth table this connects RFC (P5) to RF1
(P1). It needs to go to RF2. ? Any thoughts?

I was dealing with the same problem. With only the Main board installed I was getting a lot of noise out of the speaker and on the spectrum display. Re-seating the PCM1808 and the PCM5102 didn't help so yesterday I changed them both ... total silence.

Never used to be that way. I got taken twice at Dayton once a guy bought a nice Mobile Rig that was pristine came back an hour later said it was DOA.
When I took it home he had hooked it up backwards.
Another time I sold a nice fully loaded HF rig, guy came back said he had an emergency and needed money back.?
When I got home the rig had been gutted!?
Very sad you can't trust anyone these days.
