Hi I have sn 709 - I have my Heil HC4 from my TS-2000 8 pin conn - when I plug it into the K3 - I hear noise from the MICROPHONE???
The 'manual' says: " to select front or rear panel microphone AND to turn BIAS on/off, use the MAIN:Mic SRC menu entry.. My firmware 1.78 only shows: MIC SEL FP.H b1 A5 and I have not figured out how to adjust it - the main VFO knob also gives me a choice of rP.H and LInE In .. On a separate note - I have this anomaly that I emailed support on Friday night: "Managed to 'lock-up' my K3 - NO buttons work - including power - had to pull the power plug.... going thru the config menu - at PTT-KEY both ' OFF-OFF' tried to change values and complete lockup Completely repeatable - go to config PTT then move main vfo control and lock up. Was on AM 13840 listening to a SW station/ Changed mode/freq - still does it - as soon as main VFO adjusted. " Any advice/help comments? tnxs John VE3NFK Gary Hembree wrote: > > This is a known problem with the Rev B front panel artwork.
