The issue of the extraneous signal coming from the MHST has reached the point where it is time for a break from this project. NOODLING will afford me the time to think more about the causal factors. It just does not make sense and obviously I must be missing something.
I broke out another HB SDR which has an almost identical main board but does not have the extraneous signal issues. But this board uses the Softrock package in QUISK and not the VWS.
I also hooked it up to a 0.11KW amp, the AN 762 from CCI. In the afternoon it was like shooting fish in the barrel and great signal reports.

I might even resort to cutting a new mainboard on the CNC and using all new parts -- it is a drastic move, but nothing so far has fixed the issue.
RIP Pope Francis and we are saddened at your passing. The current Washington crowd must be sad too --- out of the news cycle for at least a week. But then again, a simple solution: Manufacture some sort of crisis to move the news cycle back to Washington.
Them that know can make it go.
