This talk about the IC-706 keying spikes got me to wondering about my
own TS990. Anyone know first hand what if any keying spikes come out of
the TS990. Can I just look at the output with a directional coupler and
a fast scope which is triggered off the keying line and get some kind of
actual idea. At the moment my 990 is torturing my trusty 35+ year old
TL922A which seems to be a very forgiving amp. Soon I will be relegating
the 922 to "back up amp " status and rolling in one of the LDMOS rigs
into the slot, I understand that some of the LDMOS amps are very
unforgiving about key up spikes even more so than the venerable A- 9500
