[Johnson] Electronic TR Switches

[David C. Hallam]

I am revising the antenna feed line of my Invader 2000 to be able to 
switch between low and high power as desired with a B&W two position 
coax switch.  I was thinking about replacing the Dow Key relay with a 
B&W 381-C electronic switch.  After reading back through comments on 
various reflectors concerning electronic TR switches, this might not a 
good idea.  Things like harmonic generation in the switch and increased 
receiver noise floor are cited.  I do have a couple of low pass 
filters.  I get the impression that unless you work full break-in CW 
(which I don't), it might be a better idea to stick with the Dow Key relay.

What might be comments on this.
