Thanks for confusing me even more about GMRS. Real Fast and Easy is a relative term....... LOL I'm going to need to watch this video more than once....!!

I could use a similar design plugged into an Arduino for long distance remote control right?

I have thrown away DTMF decoders. I figured they were trash. Too bad. Some experimentor could have used them.

How'd you get that many channels on a Gm300?

Communication Demos you can make it say that but it could really be on channel 1
