[1000mp] MP-1000 Mark-V Field (Thumps/Clicks on Break-In CW) Help here

[1000mp@mailman.qth.net]

Hi Pete,

Changing menu 7-4 makes no difference.  In fact you hear the thumps
even if you don't send any CW!!  Just push in the MOX button in and
then release the MOX button and you will hear the thump.
It happens any time the rig goes back to receive when
you have the NAR1 filters selected and you are in the CW mode....
