That isn't how the TX relays operate. it isn't a sequencer.
When you press (assert) PTT, the TX relays close immediately.
If there is a time delay value set, then RF is not transmitted until the
delay time period expires.
Example:
TX Relay-1 is connected to an AMP and it has a TX time delay of 100 ms.
ANT-1 is connected to the amp
I press PTT
The amps keys immediately
No RF is allowed to egress the ANT-1 until 100 ms pass after pressing PTT.
I hope that clarifies how it works, but I suspect that is not how you
had intended it to operate.

Tim . can you please confirm if this is correct???
Looking for some further explanation of TX1, TX2, TX3. The manual could
still use a little help or a good example.
I want to use TX1 and TX2 as a sequencer. I want TX1 to control
transmit/receive relays, TX2 to control 8877 amp.
I think:
TX1 delay 250
TX2 delay 150
Will cause:
TX1 to switch 250ms before the Flex actually transmits
TX2 to switch 150ms before the Flex actually transmits
Resulting in:
T/R relay to switch, followed by amp to key 100mS later, followed by Flex to
transmit another 150mS later.
Is this correct (or backwards)?
