[1000mp] Erratic TX behavior

[Mike Schatzberg]

Hello Brian:

Two things to try come to mind.  One is to do a memory reset, and clear out
the starting capacitance values which are memorized by the tuner.

Secondly, see if switching your antenna from the A connector to the B
connector does anything.  Sometimes that relay gets a little dirty.  If
things seem okay on the B side, try exercising the relay a bit, and see if
it will clear up, otherwise it may have to be replaced.

Good luck.

73 and Happy DXing,

Mike
