On two occasions, I had that issue with the audio blast. Only on 160m so far.
After changing bands, I held TUNE to check the SWR, it was OK except I heard TWO short, high-tone beeps when pressing the button, although SW TONE is permanently OFF. Tried again, the two beeps came again and this time, after pressing TONE again to switch back to RX, I heard a short, but deafening, scratching audio blast. Third trial: two beeps again but no blast. After power cycling the K3, all was back to normal. Only one, lower-tone beep as usual holding XMIT/TUNE. This happened twice after switching from another band to 160m. Never happened in the last 18 months up to and including Beta 3.30. K3 Serial # 586 ATU installed but always bypassed when in the shack Sub receiver installed but OFF on 160m KDVR installed 2.7 MHz and 400 Hz filters 73 Richard – HB9ANM -- View this message in context: http://n2.nabble.com/K3-Audio-blast-issue-still-there-with-FW-3-41-2-37-tp3824735p3824735.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
