Topband: Fw: Low band RX antenna question de N0AH

[Bryon PAUL Veal n0ah]

Dan sent me this email after I had just ordered the ICE 196.  I’ll be going this route- thx everyone for you responses- I don’t think 100 watts will blow out the Pro III rx from what I have heard, but all suggestions about this come with:  But, I would still protect the rx cicuit.........hihi

Hi Paul,

I fully agree.

I have developed a product to remove the RX antenna (both center conductor and ground) from the radio and substitute a 50 ohm resistor across the RX antenna terminals during transmit.
Basically, my box has an RX ant in and RX ant out terminals (RCA), two more RCA connectors for the PTT to your amp (amp keying from radio, amp keying to amp) and requires 12 vdc to operate the internal relay switching.
See attached pic.
RAP-1 $44.95 plus ship.
RCA cable $4 each (RCA male-male 5 feet long, I suggest 2, 1 for RX from box to radio and 1 for amp keying to amp) or you can make up your own.

This exact cuircuit saved my PRO2 and PRO3 from transmit energy pickup off of my K9AY RX antenna.
