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
