I completely concur. The external keyer, with PTT controlled by the keyer and internal delay of dot/dash without delay on sidetone and with PowerSDR semi-breakin turned off, is optimal for this radio. Thanks to Kirb's input on a bug which was fixed before the last release, I think we pretty much have this licked.
