MON when MON is off?

edited February 2020 in SmartSDR for Windows
Does anyone else with a 6000 hear a distorted version of their voice in the headphones when transmitting with the MON off? Just wondering if I am the only one. I know that I "hear things" but this is distracting! 73 Wayne K4ELO

    Sounds like a little RF getting into your headsets. Does it go away when you reduce power? Or on speakers? Have you tried a ferrite on the phones lead?

    Thanks George. I have rf chokes at the feedpoint of all antennas and rf beads on all leads into/out of the 6700 except the coax. Happens at all power levels but stronger with more power. Happens using either an antenna or a dummy load. Does not happen with my other rig.

    What kind of antenna are you using and what are you doing for a ground. If you cure the RFI cause you will not need the Tories and chokes.

    One vertical and two delta loops. But the problem is there on the dummy load too. Every piece of gear is grounded with a half inch braid to a common bus bar in the station. That has both a braid and a double number 8 wire going out to an 8' ground rod about 9' from the internal ground bus. Then there are 8 more ground rods around the house until the chain connects to the power line ground. Again, this problem does not occur in my other rig, a Yaesu. If this is RFI then why doesn't it affect the Yaesu?

    Wayne, did you ever resolve this problem???? I have exactly the same thing with my 6300. I do not have RFI issues here in the shack with any other rigs. So I don't believe it's RF feedback. Thanks Bill W6BWS

    Bill,

    If you reduce your power to 1 watt and the problem is still there you will know it's not RF getting where it shouldn't be. I have found all of the Flex radios I owned to me a little more susceptible to RF getting where you don't want it.
