Thanks Don,

I will check the parts mentioned.  I also have a feeling I may have some
common mode currents interfering a bit.  I've recently put up a sloper under
the hex beam.  I need to play with this.  The pop on switch to RX is more
prominent on the lower bands.  When I set the power to less than 10 watts
(KPA100 bypassed) the pop is not present.  Also... to confuse matters
more.... when I bypass the DSP and set the power above 10 watts the pop when
K2 switches back to RX disappears.

I've had this problem before and cannot remember how I cured it.  I think it
was by setting 8r to normal.

Many thanks... I'll keep this thread up to date with my progress.

Cheers,

Dave
