Re: K3 question

Hi,
Thanks for the info, I have tried that. It shows only two filters, while I have three... I need to learn how the filter process works for adding and removing filters.

I believe that just by taping the XFIL button you can change the filer being used

I thought someone at Elecraft mentioned a way to use the FM filter under
SSB at some time in the past.  That was many years ago, Is there a way
to do this?

Israel,
That error is noted in my K3 Owner's Manual on Page 70.
*ERR TXF (not tfx)  Invalid transmit crystal filter bandwidth*
*The crystal filter selected for TX (with CONFIG: FLTX) is either too narrow or too wide. You must specify a filter
that is 2.7 or 2.8 kHz wide for CW/DATA/SSB, 5 kHz for AM and 13.0 kHz for FM.*
I suggest using the K3 Utility to check the settings of your installed filters.  Fred Cady's User Guide for the K3 & P3 (3rd Edition)
has a good write-up on the K3 Utility and filter setup starting on Page 24.
