Well that's not as peculiar as it may seem at first blush. After all, many A/D
converters, fer instance the LTC2208 (16 bits, 130 MSPS) intentionally add some

Yes indeed.
Those of use with transverters would love something like
this. I would change the spec slightly to go from 26-32 MHz

well.

That is the first thing I tried. I started powering the FA-66 from

powering it off the bus, but it made no difference. I also removed all
the TX-related cables, but to no avail.

The whole point of Cognitive Radio is very simple: it's a radio
that can program itself.
A corollary of that point is: it's a radio that can and will adapt
*by itself* to functioning in response to situations and
requirements that *you don't and can't in principle know yet*.
