Default Frequency channel communication problems

hi all. ive got a big problem. a flying club is looking at a site across from my house, within 500ft. if they get it, which is certainly a possibility, then im going to have problems communicating to them the frequency im on. i have a caliber 30 w/7-ch 72mhz PCM/PPM transmitter. id like to solve this problem without leaving the house. are there any spread spectrum helicopter systems? i know there arent any now, but are any planned for release? what about other options? i was thinking frequency jammer, but im not sure if their legal for civilians as they could interfere with alot more than RC models. and it might cause my own model to crash.

help.


thx

Why not talk to the prospective club leaders and mediate a solution with them?
Become a member and/or a director and work with them toward a solution . maybe they will offer you a no charge membership if they understand that
they are now in your transmitting area, if you agree to operate your equiptment within their frequency management system . Or maybe they can block out
your frequency from use at that field ...

Or join the club and go hang out. I'd spend as much time socializing or more as actually flying.

Most likely they are an AMA club. AMA rules require that a club that's relocating negotiate frequency sharing with existing fields that are within a certain distance. If you're not going to join them, you should be able to negotiate exclusive use of your channel. Of course you might also be able to negotiate free membership as long as you live at that house. Having a member so close to the field would be a bonus for any club. Work with them and you should be able to end up with a win win solution for everyone.

Send a letter to the club president and copy the person at the AMA who is in charge of helping with field acquisition. Don't demand anything, just let them know (in writing) what channel you are using and ask that they work with you to come up with a solution that works for everyone. This will establish you as the existing user of that frequency in that area. Leave the solutions out of the letter. After talking you may actually come up with a better solution.

I would recommend setting aside a couple of channels for yourself and ask the club to outlaw these channels.
If they do it then you should be all well and good.

You might want to read more about the Spektrum Radio. It is a computer radio and it DOES support helicopters. It may not have as much functionality as a 9C but it should work fine for many simpler heli setups.

not sure if that is true or not, but if so the antenna's are only about 2.5 inches long each...

check out the pdf on spektrum's website. the rx antenna looks about the same as the tx, except instead of a stubby it is just wire. maybe 5 inches long or so.

at 2.4 ghz a full wave antenna is only 4.6 inches, any longer will hurt efficiency, not help it.
