You all know “that guy” – The one with the UHF/VHF antenna (or antennas) stuck to the roof or trunk lid and wires trailing off to the side that go through a trunk, door, or window gap.

Some of you drill holes for microphone clips, or purchase alternatives that clip onto an air vent, and some of you simply toss the microphone in a cup holder. Today, I am going to share my solution for making a magnetic microphone mount that does not require holes in your dashboard.

At the heart of it is essentially a UV-5R or UV-B5, with the added band of 220Mhz, in a mobile friendly package, with 25 watts. You can read some some great information at Miklor, so there is no reason to reinvent the wheel here. It is a dual watch radio, with the typical awkward menu system typical of these radios. But once you have programmed a memory location a few times, it goes fairly quickly. And as is also typical, it is easier if you use either software from the BTech web site, or Chirp.
The “mixed bag” experience primarily deals with the transmit audio being fairly muddy, muffled, and dull. One cure is:
