Having trouble with one of my three K3's, sn 02138, generating ERROR TXF. Radio had 3.97 firmware, which I updated to latest version as of this morning. CW transmissions are fine but any attempt at SSB transmissions results in ERROR TXF. Don't know how long it has been like this as I rarely get on SSB. Radio has the stock 5 pole 2.7 filter in FL1, plus CW filters in other slots, but no AM or FM filters. FLtx Sb is set to FL1. FL1 is enabled ON. FL1 BW is 2.7. FL1 freq is -0.78. I have a spare (new) 2.7 filter that I even swapped with the previously installed one, plus I changed the filter position (and reset the configuration as required). I checked all above via radio CONFIG MENU on screen, and also with the K3 UTILITY. I tried it with VOX and without. I tried it with tapping XMIT button. I tried it with MIC plugged in front and in back, and with no mic plugged in at all. (MIC is Heil Proset.) I have checked and re-checked the filter settings and all seems to coincide properly unless it is just a "forest4trees" thing. I did try the above on 160,80,40,20,15 and 10m.
What did I miss? Help??
