Like I wrote in another thread (Poll:
How Long Have You Been Into Radio Communications?), when I was about his age (a little younger), I was taking the crystals out of my handheld CB radios and mix-matching the pairs to create different TX/RX combos.
If you actually read what Landon has written (posted) in this thread, he is a scout (I am assuming a Boy Scout or maybe an Explorer Scout) and his troop uses GMRS (FRS) on camping trips; and for the RX, all he wants is FIRE (not police). He never once wrote that he wanted to TX on any unauthorized frequencies. As for the GMRS (lic req), I think he, as many other people do, is confusing it with FRS (no lic req) - or maybe he and/or his scout troop has a license.
When I was a Boy Scout on a camping trip, I would have liked to have been able to hear the fire dept or rangers. When I was an LAPD Explorer Scout, I wanted to hear the police frequencies (although, we had our own police radios).
When I was in the Civil Air Patrol (CAP), we tweaked our own radios to get the freqs we wanted or to hit our repeaters.
I had my own scanner back when I was about his age. When I was a kid, if I had the money, I would have probably wanted the exact same thing he is asking for - a radio that I could transmit on to talk to others in my group and be able to hear (RX) the police/fire, etc. I always dreamed of having a scanner and a radio all in one unit...then I bought my iCOM W2A that does just that (but it's a very delicate radio).
I wonder if any of you naysayers ever tinkered with a radio (when you were a kid or even now) and made it do things that weren't quite "conventional" or took apart things to see how they worked and tried out new things. "Let him who is without sin cast the first stone."
I think some here belong to the group called the Cynics who follow the philosophy of Cynicism - Antisthenes would have loved you guys.
Landon, if I had the equipment, I would do what I could to help you out (within the law), but I don't...hope you find what you seek.
