Again, the lower frequency gives you a lot more penetration, and more bend. There is always some penetration and bend. When I said that an obstruction affects your reception, I didn’t mean that it blocks it. It just weakens the signal. The stronger signal in the 2M rigs means that you need less of the signal in order to receive it. I just looked up the Vortex 170 that Footflyer suggest, and it has a max power of 5 watts. That is 10 times the signal strength of the FRS radios at 0.5 watts. Before they restricted the use of the repeater on top of Pike’s Peak, I was able to reach it from the other side of Limon. There used to be a repeater on a 400ft tower at Sheridan and US-36 in Denver that I could reach from Castle Rock.

Ok, that brings me back to my origional question because if the 2M radio a stronger signal, but is only good within LOS, then I don't see the benefit.

Unfortunately, any obstruction counts. That means that if you come down behind a hill or large building, it can affect your reception.

So, if I don't plan to fly further than 2 miles, I'll be fine. If further than 2 miles away, the 2M is the way to go, right?

Hi Robert,
The FRS radio operated at approx. 460 MHz, and at a power of .5 watts. This gives it a range of about 2 miles if you are at line of sight (LOS). The range is considerably less if you don’t have LOS. The 2M rigs we are discussing transmit at approx 144 MHz, with a power of approx. 3 watts. The lower frequency helps get penetration and a slight bend. You are still somewhat dependent on LOS, but you have more leeway. The upshot is that you have a stronger signal, and better coverage.
Ron.

Ok, now you have my curiosity going. What are the advantages over my simple Cobra radio with a 2M radio?

Hey Jerry,
I have been planing on trying that as well. There is an interesting article on Jeff Goins footflyer site about his communications setup. He is using 2meter and he is selling kits for special high quality microphones to go with them. He also lets you know what parts he is using and where to get them. The PG community has been using these for a long time now and a bunch of the PPG clubs have gone this route as well. I believe the Florida group is using them also.
In any case, thats a long way of saying that I'm in.... I know that John is going this route and Mathew already has a 2 meter radio.
Alex...

communications. Anyone else interested in getting a 2M radio. I understand they are becoming quite popular at some of the fly-ins. Pipe in and let us know what you think. I in.
