Hi, No I'm afraid not.
Mic only selected. Iain ----------------------------- Iain This rings a bell with me, but it's way back in the past so my memory could be wrong ........... Do you have MIC+LIN IN turned on ? (sorry I'm not near the rig at present so the exact terminology may be incorrect). If so try turning it to just MIC on and see if the issue is solved.

Hello, While trying to adjust the mic equalisation I am getting a continual low level high end electrical noise, like whistle or very slight feedback through while monitoring on headphones or speaker. With more compression it brings it out more obviously but it is there with no compression. It is there even on low mic gain but much less. It even persists even with no microphone, data lead or cables plugged in. I have unplugged EVERYTHING apart from the power, put monitor speaker on, and PTT and it is there. At zero mic gain no noise but it rises as the mic gain does. If I cut the extreme high end it goes a little but I need some high end boost for my mic. Its not to horrendous, its only just perceptible I shouldn't think it wouldn't carry through to audio with a 2.7Khz bandwidth but I cant be sure. Can I just assume its just internal noise being picked up on the monitor amp or do I have to worry about my TX audio quality? Has anyone else noticed this effect? Do I have duff mic pre-amp shielding somewhere?
