[Elecraft] Need "Error TxF" help - SOLUTION

[n5qq61 at gmail.com]

Thanks Vic, Don, David and Peter for replies. But yesterday I found
the root cause. I'll summarize quickly the chain of events as maybe
some others are blind as me.

1. I had removed the 6khz filter when I got the radio, as I wasn't
going to use it.
2. The previous user had apparently used the radio in ESSB mode
indicated by that little "+" sign in the bottom RH corner of the
screen.
3. Config menu item "TX ESSB" was set to ON.

With ESSB mode "ON" the radio over-rides the FLtx SB setting used for
LSB and USB (which we had all focused on), and shifts to the required
6khz filter for ESSB transmit. And without that filter installed and
enabled in the radio we get the error.

I turned ESSB off, and the USB and LSB work just fine.

Thanks again
Ron
