Have been out from home for some days now, but I'm back, and have just rewired the Mic. Works fine on all bands except 15 and 10 meters. It's not so bad on 15 meters, but 10 meter is really bad. I know my antenna is out of tune on 10 meters, but it's not even supported on 12, 17 and 6 meters, and there are no problems there.
Have tried ferrite bead on the mic cable, but does not seem to make any difference. 73 Ulf -----Opprinnelig melding----- Fra: FlexRadio [mailto:flexradio-boun...@flex-radio.biz] På vegne av Tim Ellison Sendt: 26. oktober 2012 03:42 Til: flexradio@flex-radio.biz Emne: Re: [Flexradio] RFI on 10 meter Check the wiring on the mic cable. If it is a Heil cable, the MIC- and ground may be bonded (connected) together (they should not be connected) and the ground/cable shield may not be connected to the shell of the 8-pin Foster connector (which it should). Then try a ferrite bead on the mic cable. -Tim On 10/25/2012 5:51 PM, Ulf Holt wrote: > > Some more info. > > Antenna is Butternut HF6V mounted on the barn using the metal roof as a > counterpoise. > Mic is Heil HM-5 > I have a ground strap from my FLEX to the PSU on my computer and also ground > to a copper plate buried outside the barn.
