Hi Tim, No I am not, I would with some Linears however the low current on the PTT circuit is one of Tokyo High Powers claim to fame in the specs dept. This phenomina is NOT exhibited on Icom IC7000, IC756 III, or IC7600 (the only ones used on it to date apart from Flex5000/3000) so I was kind of hoping a firmware refinement may be the go for a polished product, certainly the Audio Thump was, It "appears" as if it is sending the relay to ground at a fast pulsing while the Flex circuit power dies away. I would suggest that a sensetive buffer may do the same. It's Interesting but something you don't like to see happening if you forget to turn of the linear 1st.

Hi Guys, This seems a minor annoyance when powering off the Flex5000 in that the PTT to ground out makes the linear relay chatter at high speed for 1~1.5 seconds (Tokyo High Power HL-1.5KFX). The simple work around is to turn the linear off first. Could this be a firmware refinement in a similar way of improvement to the audio "ka-thump" now appears fixed in the latest firmware ? (or at least it appears that way) 73' James.
