Re: [RCSE] Frequency Scanners
Remember, a scanner on the ground, will helpo identify the pilot who left his transmitter on after he landed and put his plane away. But, when you get hit in the air, don't think you are going to find the problem with a ground based scanner, unless it's someone else at the site. When airborne, your model is in an entirely different arena as far as interferrence is concerned. So be careful. Don't put too much faith in a ground based scanner. Now, for a reccomendation. One of our memebers bought a scanner from a highly rewspected manufacurer a few years ago. We were not impressed by it's selectivity. You could hear a transmitter on a the flight line on at least three channels, and sometimes 5 (the primary, say ch-42, and adjacent, ch-41 ch-43and often ch-40 and ch-44). As a HAM, I pruchased a Yeasu VX-5R for 2-m,eter and 440mHz use and was impressed that it also tunes the 72mHz band. When it is set to ch-42, it doesn't respond to any other channel. Makes a real good scanner. .bcAG4YQ Williamsburg, VA On Tue, 18 Jan 2005, Adam Till (Cal) wrote: Thanks for all the suggestions folks, lots to think about.

Re: [RCSE] Frequency Scanners
A couple of our club members have ICOM IC-R2 hand-held receivers. These cover a very wide spectrum -- 500KHz to over 1GHz -- and because they're receivers they help you identify the interfering signal. The problem with scanners is that our 72MHz signal gets attenuated rapidly in built-up areas so a model transmitter's reported strength will drop off to unnoticeable after just a couple of streets. This means that you could easily get knocked out of the sky with a signal that just didn't show up on the receiver. The only way to fix this is height. I have been experimenting with an active antenna for these receivers. Its used for Foxhunting, a hobby where you have to go and find hidden transmitters. Its highly directional so the plan is to use it to trace interfering transmitters. It works well but we've had no chance to try it out recently for real since the band's been clear. (The interference is lurking out there, though. I finnally spotted what I was looking for last weekend -- helecopters. I thought this might be going on, we needed someone using R/C that wasn't using a large open space and only flying in calm weather. I spoke to this pilot who told me about the other fliers in the area, there's a bunch of them and none seem to be aware of other R/C activity, clubs, AMA or anything like that...)(He was flying a 40 sized helecopter by himself) Martin Usher RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Frequency Scanners
I recommend the Aerospectra unit, have had mine for 10 years and the service support and performance are outstanding. Not cheap, but it's truly an investment. If your club puts on a good sized contest, you should have one. Does 72, 75, 50 and Ham bands. One user's opinion.

Re: [RCSE] Frequency Scanners
Have a look at http://www.llm-electronic.com/ this is a very nice unit. I am using the 35mhz one in the UK but they also do 72mhz.
