[Elecraft] Fw: K-3 ERR TXF issue

[Dick Dievendorff]

The Owner's manual description of ERR TXF says that it means invalid 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, 6 kHz for AM, and 13.0 kHz for FM). 

Using the K3 Utiltiy's crystal filter configuration dialog or K3 front panel
CONFIG menus, verify that the filter selected for *transmit* is the required
width for each mode.

If you've set the radio back to its defaults, you may need to change the
CONFIG menu for KPA3 to "PA NOR" or you're not using the KPA3, and the
maximum power level would be about 12W.

The factory configuration default for KPA3 is "not installed". 

I'd also check the CONFIG menu options for all your other installed options
(KBPF3, KAT3, all crystal filters, etc) to make sure they match the options
you've physically plugged into the radio.  And if you've restored the rig to
factory default with EE INIT, you might also want to run TX GAIN calibration
again.

Forgot mention additional problem; after the reset, the power will only dial
up to 12W, not the 100+ seen before.

Just had the radio for a few days, it was factory assembled and is almost
new 
but I am the second owner. It worked fine for a few days then I starting
seeing 
this error message (ERR TXF) when using the ATU and now get it everytime I
try 
to transmit. 

I checked the FIL settings for the 3 positions occupied and it seemed they
were 
good. Finally, I reset the radio back to defaults and still no success.
Any suggestions appreciated.

Jack,
WE5ST
