I have had this problem with ALL soldid state instruments used on my 160m
antenna.
There is a brute-force solution - use a GR-1606 bridge.  These are available at
some flea markets.

I got one at Dayton last year, and while it requires a separate oscillator and
detector, it works beautifully, even in the presence of strong daytime BC
interference. I use an HP sig. gen. for the source, and an old transceiver as a
detector.

The size and weight of the three pieces of equipment can be a problem.  I have
made up a portable test bench on a wheelbarrow to lug the stuff to the base of
the antenna where I make the adjustments.
