That is true, the FRS radios can also use the GMRS channels. So the difference is the amount of power and the bandwidth. So can anyone tell how much power we are running by listening? They might be able to tell the bandwidth maybe. I would hate for the GMRS police to get me. Haha!Yes, the rules basically state that everyone transmitting in your group needs to say your call sign every 15 minutes, but as you probably know, there’s an exception clause that’s very confusing and if not argumentative. The FCC suggested that a unit number be placed after your call sign for each member. That’s what I would do if I was working through a repeater. When using the radios to talk with family or associates that's within a mile, I would use one of the FRS simplex frequencies that is shared with GMARS, particularly if your radios can also be narrow banded at 2 watts on those frequencies.
You're replying to a 2 year old postCB but, unless you got FM with toned squelch by running some exotic imported rig, "10 meter radio" or converted low band gear, there is a good chance the other operator will turn his shit off after 15 minutes. Especially if you talking to a wife/daughter or girlfriend
We use the MURS frequencies, good hand helds get out about 3-5 miles, mobiles with a decent antenna about 10-15 miles, my base station 20-30 miles, and the frequencies are usually very quiet.That I don't understand because we use GMRS hand helds in Deer hunting season in northeast PA ( hills,dales, & trees ) no line of sight. Granted we are not at great distance apart but they work OK for us and are Quite. You have to make sure your all using the same security code & channel. I have bumped mine off channel before. I laugh because some guys in the group hate when someone talks until they need help. LOL
