don2,
I tried something like this–only partially successful, however. See: Can I Use My Smartphone as a Remote Microphone - #28 by ThomF
Or better, yet, I’ll repeat it here:
I ordered a wireless lapel mic, with the intention of using it with a TV Connector (Phonak/Kirkland) to serve as a ‘Roger-type’ device with my KS9s. The mic/receiver took a long time to get to me–it was ordered out of China through WISH, and with extended shipping delays due to the pandemic I didn’t get it until mid-April.
This is a picture of the contraption:
The black box under the TV Connector is a Li-Ion USB battery to power the TV Connector. The receiver from the lapel mic is plugged into the TV Connector. To the top-right of the TC Connector is the lapel mic.
It works, although not well. I didn’t realize it when I ordered it, but the lapel mic and receiver are single channel (not stereo). As a result, I only get sound in one ear. And the sound was a bit unsteady, although that might simply have been because the various connections weren’t as secure as they could have been.
This would have been a low-cost solution, if somewhat ungainly. I’m looking for a better mic/receiver combination–one that is self-powered, but two-channel and yet relatively inexpensive.
If anyone has a mic/receiver recommendation, I’m all ears (so to speak).
