    No problem! Just remember, the VFO changes the RX and TX, whereas RIT only changes RX.

    Let us know how it works!

    I dont think either of those options alone will work.

    The shunt diode will clip the audio peaks to the forward bias drop of the diode (.7v) and make the audio sound all square wave like and...

    MURS is in part 95 and part 95 states it must be a part 95 radio. All this was found under the link I provided in post 3.

    95.2763 MURS channels.
    Five VHF channels are allotted for shared use...

    Could be a bad rectifier in the alternator... There are 6 rectification diodes in an alternator to turn 3 phase ac into dc.

    edit: unhook the alternator and see if the issue clears up

    Those are fun, every walmart in the country uses 154.600 or 154.570. When you say hello to them, they get mad like they own the frequency. Iu would think with how big walmart is, they would just get...

    and if you get a GMRS license, it will cover your whole family. But, that still doesn't let you use the part 90 baofeng for a part 95 service. A ham license lets you (and only you) use the ham bands...

    The coating doesn't have much to do with surface resistance. I agree with K7KBN there. What adding a coating does is change the velocity factor of the conductor (but not enough to be concerned with...
