I remember the ACOM had a problem with keying. My Alpha 99
(vacuum relay) never had the problem, and still keys fine on 2.054 as
well, so I'm thankful for that. I don't seem to be seeing any leading
edge spikes from the LED metering on the Alpha - don't know if it would
be visible, but with LED's at least I have the possibility of seeing it.
Just for comparison purposes, my settings are:
CW QSK = 5%
Ext T/R Delay = 20% (but is this really used when using the
Monitor is definitely a problem, but I think it's the same thing
they just fixed on the Orion II's 2.030 version. Hopefully we'll see a
fix for that quickly.
I'll do my sweep mod over the weekend when I can carve out a
little more time for it. Will be nice to have it for navigating the
pileups on 3Y0X - hi!
