Hi Rik, Marco, Andy and any others who asked about the ts850 mod

 

The info came from Bob Vernall ZL2VCA

 

http://we0h.us/Amateur_Radio_stuff/TS850/ts_850_lf_tx_mod.pdf

 

and yes, it does seem to fool the synth into thinking it is still in receive.

 

The output (via the transverter socket) is less than a volt - hence the PA.

 

I feed a positive voltge into the transverter socket from the PA to activate the

changeover relay inside the ts850.

Hi Graham -

Make that 4! I've modified my TS850 to generate SSB at 500 kHz and use a homebrew linear PA to produce 30 watts peak RF.

Have been off air for a while during a shack rebuild and broken aerial but am back in business.
