Ah yeah that's no good then.  Ah well, we keep fishing through new ideas 
for workable stuff!

The site in question is plenty remote, but I'll still put a notch on the 
image, and on the local pager and FM radio station too, even though they 
are 10km away.  It's no work at all to put a coax stub notch on something.

Cheapie Baofengs with some coax bandpass/notch reject will do it, EXCEPT 
that the repeater is question is Six meters.

Now looking for inexpensive 6m handhelds, or other RX boards.
