Hi Mike. My K3 is left on most of the time so I haven't noticed it at startup ... But I did notice sporadic significant reductions in the audio level on 30m the other evening. At first I thought it was someone tuning-up zero-beat on my frequency and triggering the AGC, but it wasn't that. Next I thought there might be an intermittent antenna connection but the SWR was fine and the coax cables in the shack, at least, are all fine. I've had a similar problem in the past with a sticky antenna change over relay in the amplifier (sometimes on going to receive the RF level is way down because the relay hasn't properly closed - a quick tap on the PTT usually fixes it, temporarily), but on this occastion the S meter level looked normal. So I'm foxed. I haven't noticed it since. If it happens again I'll take more notice of what's happening and might even record it. 73 Gary ZL2iFB PS The end literally dropped off my K3's AF knob yesterday as I touched it - the knob appears to be crumbling like dry fruitcake. It hasn't been knocked or abused, just used normally. Elecraft kindly already sent me a set of replacement knobs due to the outer ring/knobs cracking over month ago so now I really must make time to fit them! ______________________________________________________________ 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
