Wow, that was a long and frustrating troubleshooting session. It even made
your wife unhappy. You can't be blamed in being disappointed in the first
experiences. I can hazard a guess at what was happening: the Flex was
switching RX to TX faster than your amp was able to ramp up. Maybe ever faster
than other transceivers you have been using. So, your amp was hotswitching.
Adding this delay slows down the Flex' RX to TX switching, giving the rest of
the chain time to catch up before putting out RF.
I use some TX delay (100 us) to increase the life of the switching relays in my
(solid state) SPE Expert, but even without it, I've never seen the thump
you've been experiencing. Hope you enjoy the new and different ergonomics of
the Flex, and get to enjoy its features. Jim KJ2P > Date: Wed, 4 Jan 2012
