Hello All,
Can anyone help with ideas on how to set up manual switching to Tx
in CW mode. I wish to put the K2 into Tx without sending ANY RF to allow my
Transverter time to run through it's fully sequenced switching.
At present every time I hit the CW key, a burst of RF gets shunted up the back
end of the last receive amplifier stage in my transverter for about 700ms
before full Tx switching occurs in the transverter.
As yet I haven't "blown" any devices up as I have placed Back -to-Back diodes
to limit the RF voltage that the MMIC in the IF path sees. However I feel
there MUST be a more ele-gant solution! ( I am using my K2 for EME purposes, so
it is more important to look after the LNA then the transverter IF chain)
It is a pity that there cannot be a delay placed in the software, or otherwise,
on when RF actually begins to appear once the K2 is keyed.
Anyone driving a QRO amp. resolved this problem. I suspect not too many
running the 100 W version of the k2 to drive a 1500W amp would be happy to have
the instantaneous RF on their output relays?
Perhaps I have missed something about this along the way?
Regards
