[TMRA] Schottky diode question sorta

[KB8NXO at access-ohio.net]

Thanks. It seems like I was trying to reinvent a TR switch. I don't know why 
I never thought of a TR switch. I think I'm the victim of too much 
advertising. I tried looking this up in my 2007 Handbook and 2010 Antenna 
book and there was no mention of it in either. Go figure.

I once had a receiver and a transmitter on the same antenna.  It was wired

so that when I hit the push to talk button, an antenna switch directed the

antenna to the transmitter, and isolated the receiver.  I have not seen one

of those switches in a long time.  As a novice in 1980, I was using gear

from the 1950's; prior to that I used a manual antenna switch.

I have 1 radio that I want to use to receive only(HF). I have 1 radio that I



want to transceive(HF). I have one antenna and feed line. Can I use a diode 

and T the two radios together without overloading (damaging) the receiver 

when I transmit?

Thanks in advance.
