Paul-This problem is almost certainly related to the filter relays on the
LPF board. Early Paragons used reed relays to select the LPFs, but this was
a pretty expensive approach. As a result, in later units Ten-Tec started
using inexpensive frame relays instead. I had a Paragon that would do the
same thing you describe only on the 80 M band, and lightly tapping the top
of the cabinet near the PA heat sink would bring signals back to normal.
The relays are available from Digikey, they only cost about $1.35 each. If
you decide to replace the defective relay, I highly recommend that you
replace all 14, it's a lot of work to get the LPF board out and I can almost
guarantee that another one will probably fail if you leave the other
originals in place. However, check to see what type of relays you have
first. You wouldn't want to replace all 14 if your LPF board uses reed
relays.

If I tune up from 6.000 mHz, when I hit 6.500 there is a click and the
signal strength drops way, way off. I can hear signals very faint. I
continue up to 10.500 and it clicks and signal strength kicks back up. Any
ideas how to cure this?
Thanks,
