Many of the communication radio problems happen when the illegal operators are stepping on the broadcasts of others, especially corporate company men that are in compliance and very serious about their chosen frequencies of use.
Several years ago I was so close to ordering a 25 watt fm transmitter to use during fishing tournaments so the entrants could keep up with the hourly results without checking in at the weigh-in station and spend their time fishing instead of running back and forth. Changed my mind after looking up the FCC regulations and found out that without a license it was only possible to transmit a signal for about 100 yards and they get very serious about the power of FM transmitters.
In many areas, certain groups and companies have chosen the channels they use and stay on them all the time and some operators will scan all incoming signals and pick one for that day's use. Those stationary users get quite peeved when outsiders use their so-called channels to communicate on and will write you up if they can identify you.
When they became available in handheld models, we started out being licensed CB radio operators because of their range and had to take care in not stepping on others' use when we would go into new areas to work. Those CB operators were very territorial and I have even spoken with other CB operators to find out who is using what channel. They were awkward to use in the field with their 4ft extendable antenna. I've seen some modern models that look very desireable with a floppy antenna.?ÿ
Then there were the few that had linked on to some super-powered linear amp that would allow them to cut into television signals and take over the local airwaves stepping on everyone's programming.
The dual-band CB Ham radios HF transceivers with a range of 6?ñ miles in combo with Radio Walkie Talkie Radios are probably the wave of the future for two way radio communication. I believe they need to be programmed by connecting with a computer.
Now I use Waterproof Uniden GMR36892CK radios that also have FRS band that I can use without a license. Very durable and long battery life it is a shame that they are now discontinued. By rotating the use of 4 radios and having two never used new ones on the shelf, they will probably be the last radios I will ever use. Still have about 6 operating basic FRS radios for the grandchildren to use.
I stay on channel 5 as I rarely hear anyone on there except me locally. The longer-range GMRS stations are there if I ever want to get licensed.
When we get beyond the range of the FRS channels we usually dial each other up with our cell phones until we get back in range for the radios.
Radio Shack had handhelds that were 1watt and 5watt models and they would reach out there and I had two of each and they are long gone.
The RTK users with UHF band can freely use up to 900 Mhz and everyone with their 1 watt to 35watt radios are the people that really need to get in compliance with their licenses.
