The TE manual gives some simple instruction for hard keying the amplifier but
out an abundance of caution I want to verify my understanding of them before I
start cutting wires and adding relays.
The DEMI sequencer gives a sequenced PTT ground to enable the amplifier. The
TE instructions are to cut the internal shorting wire between pins 5 & 6 and
then connect the PTT ground to pin 2.
To enable the RF amplifier the TE instructions are: 1) Connect pin 5 & 6 then
2) connect pin 2 to PTT ground.
My interpretation of these instruction are:
I need to use the PTT ground to close a relay that connects pins 5 & 6 and then
use an output from this relay to close another relay that connects the PTT
ground to pin 2 on the amplifier.
Is this correct?
Is there a better way?
