If this is with regard to 440..it is so very line of sight dependent, that most people cannot hear you if anything at all is between you. If you have a rise between you, it will block the signal. It doesn't follow terrain well.

As far as chattering among a group with 440 simplex, the limitations of the band apply to your advantage too. Very few guys have 440 antennas at high enough elevations to pick people up at real distance, so you won't really interfere with anyone.

If anyone heard a group in a remote area on 440 simplex, they would likely be more curious to make the contact than irritated by the chatter.

I put a 20W 440 repeater up on a 40' tower thinking it would easily cover the local town here...and it wasn't even useful. Was my first intro to the properties of 440 'line of sight' for sure. Now it's at 375' over avg terrain with a 90W amp and a GAsFET pre-amp on it and it's 100% more useful.

Get it working right for the situation and it's a great band, but it does require some experimentation to learn the properties.
