I've had a look around at some other posts that people have made but I've not really found an answer that helps.

I've always had to choose my microphones carefully because I'm disabled and cannot hold the microphone so hand microphone is totally out of the question. I have used base microphones before but now use a Heil Pro 40. I use a foot switch on my worktop in order to TX the microphone. So basically I want to know what Heil microphones work well with this SDR radio
