There has been a lot of discussion on this topic recently on all of the
I will copy all three groups with this, and I apologize to those of you who
receive it three times.
I have created a web page on this topic, show pictures of three typical
types of T/R relays you may find inside an amplifier.
BTW, ?T/R? means Transmit/Receive. It is the relay inside the amp that
bypasses the amp in RX mode, connecting the antenna directly to the
I point out the different sequential timings of the Orion, OM7, and Eagle.
I also explain why I think TEN-TEC should extend these parameters of them on
all three models.
I suggest several different ways of addressing this problem.
Which method will work best for each of us depends on several things:
¨ Which amplifier we have and what kind of relay technology it has
¨ Whether we want full-QSK or simply clean (not hot) switching
¨ Which transceiver we have
In some cases additional hardware is required.
I show a couple of products that will work and I contrast them.
GUYS, I have put this together quickly, mostly from memory.
I am not the sharpest tack in the pack.
Indeed most of my friends are a lot sharper than me, but with their help, my
web site keeps getting better.
PLEASE SHARE FEEDBACK with me, especially corrections!
