Rodger,
I built several of them for my station as same as for our local contest
club station and all works like champ. (Martin's version)
State nr. 1
QSK T/R is floating
Re1 - closed
Re2 - open
Re3 - open
In this case ANT port is connected to RX input port and AMP port is
floating.
State T/R is grounded
Re1 - open
Re2 - closed
Re3 - closed
In this case ANT port is floating, RX input port is grounded and AMP
port is grounded too.
Hope it helps.
73 - Petr, ok1rp

Subject: Front End Saver for Top Band
Date: Thu, 29 May 2014 18:45:14 +
Has anyone built the front end saver by KD9SV or the OK1RR version which
uses 12 volt reed relays.
I am attempting to build the 12v version on veroboard and have the
following query, when the unit is supplied with 12v relays 1 2 are
energised, when the PTT is operated relays 2 3 are energised basically
relay 2 remains energised at all times, is this the correct sequence of
operation?
thanks Rodger/GM3JOB
