Hi All.
I am using a K3 with internal 144 transverter module.
On 2m I use a sequencer for TX/RX as I use a PA and a LNA at the masthead.
The rig TX is triggered by the sequencer by using the PTT In line.
The sequencer ensures the rig is switched after the LNA. The sequencer is
triggered either by

Ok Roger - thanks for the input.
TX-DLY is an option I suppose but that means the sequencer will not be
sequencing in the right order. ( I dont know if that is an issue or not).
The sequencer has to switch the LNA first then switches the PA and K3 over
together to tx. TXDLY. If I use TXD then they

Seems to me this -could- be done, but would require some modifications to
your sequencer system.
Using the TX INH input (pin 7 or AUX connector on the K3, set TX INH to ON).
You would need an output from your sequencer that stays low until TX
permission is desired. This operation would be
Thanks Bruce.
The sequencer is an SSB DCW2004 B. It does not seem to have a state-change
output from rx to tx. It has inputs to earth or high to trigger the sequence
and then delay outputs to sequence the devices.
So I am note sure that would work..

Roger,
You would add your own output that would stay low until the sequencer out
for triggering the PTT on the rig is active. This output would also only
inhibit the rig when on 2M (a requirement you mentioned), by monitoring the
band data outputs of the radio. You would have to build this logic
