Today I used the K3 utility to adjust a crystal filter gain. After making the adjustment to the 500Hz filter and closing the utility I had a QSO on 40M SSB. They reported that I sounded nasal and was very difficult to understand. After a power-off reset transmit audio returned to normal. I have seen this situation from time to time since I have owned the K3. I suspect but don't have a way to tell that I was transmitting through the 500Hz filter. Listeners said it was like I was off frequency but no amount of tuning helped.
Filters are set up as follows: Fil 1 13.00 KHz enabled for CW, FM, AM; with Tx FM Fil 2 6.00 KHz enabled for CW, LSB, USB, Data, AM; with Tx AM Fil 3 2.70 KHz enabled for CW, LSB, USB, Data; with Tx CW and SSB Fil 4 0.50 KHz enabled for CW and Data, no Tx Fil 5 Blank, nothing enabled K3-100 #508 Utility version 1.1.6.3, standard RS232 connection MCU 02.38 FPF 00.02 DSP1 0.190 Mike Scott - AE6WA Tarzana, CA (DM04 / near LA) K3-100 #508/ KX1 #1311 _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
