Hi guys ,i noticed when i key up on fm there is a slight buzz in the audio & it picks it up even worse if i put the mike close to the inbuilt transformer inside the rig.Also if i go on usb the audio warbles ever so slightly on the edge of my audio using the standard mike & increase's cosiderably if i put a power mike on it,these problems exist whichever part of the rigs bandwidth i use & the vco can looks like it has never been touched.Any idea's / cures to these problems? Cheers in advance

Check the voltage the PSU is set at, it may have been turned up too high, or try it on an external PSU to see if it still does it.

Hi Dave, it does not buzz if i use an external psu unless i put the mike near the PSU , any idea's to sort it? Also the warble is sorted, had too much v.d.c going to the clarifier.
