[Heathkit] DX-20 T/R Switching?

[Curt]

Well, yes of course a knife switch would work (and maybe that is the only 
reasonable option).  But, even as a novice in 1960, a relay powered from the 
auxiliary connector on the back of my Eico 723 didn't seem exactly high 
tech.  The setup was just like what I built for the DX-40.   Switch to 
"standby" and listen, switch to "CW" and transmit.  The DX-20 
standby/transmit switch evidently grounds the center-tap on the HV to 
transmit.  I'm wondering whether anyone has replaced this switch with a 
double-pole, then used the other side to switch relay power.  Actually, 
somewhere I recall reading that the existing switch has extra contacts. 
Maybe that is too much butchering, but after all these were kits in the 
first place.  Thoughts?
