Dear K3 reflector- I have a question regarding my new to me K3- 100 with ATU. Although it seems to work well, when I turn it on, I hear a fairly loud high pitched motor-like almost hissing sound, lasting for about two seconds. This sound is not always the same loudness, but is nearly always there. This happens whether the ATU is off or on, and with nothing connected to my transceiver except for the power supply and antenna. My transceiver is in the 600 series serial number range, and is stock except for the ATU, TCXO, 100 watt module, and a 400 HZ 8 pole filter. I seems to come from the right side of the rig. Should I be concerned? I am using latest firmware.
Thanks, Dan ______________________________________________________________ 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
