[RTTY] RTTY Digest, Vol 41, Issue 26....Yaesu FT-1000 MP Mk 5 power "drift"

[Dr David L Kepkay]

Well, I have been thinking this over and listening to some comments ffom 
others. The gist of the creaping drive power on RTTY must not be overheating 
(or anything else wrong)in the pair of MVFs  themselves,  since it doesn't 
happen on SSB (mic to my TV set turned up loud) for 1/2 hr or CW (key down 
for 5 min (twice as long as with RTTY transmissions mentioned earlier) and 
it occurs on both rigs. It must lie with the audio change of the AFSK via 
the Rigblaster...I think.

The observation that it doesn't occur on SSB further supports this, although 
it is harder to stress the MVF in this mode.

The options now include bypassing the RigBlaster and adding a new sound card 
to replace the integrated one (which I suppose could overhear easier since 
it is on the motherboard.

Does this make any sense please?

Thanks,
