Default Range check questions?

I am range testing my Futaba 6exa and Conquest radio's outside of the airplane. My observations are as follows:
(1) With antenna down, I start getting minor servo chatter at about 75 feet.
(2) With antenna fully extended, I start getting minor chatter at approximately 350 feet.

These tests are with fully charged batteries and the receivers and servos outside of an airplane. In both cases, the TX will still operate the servos correctly but there is some minor chatter when the TX sticks are not being operated.

Does this seem correct are should there be no servo chatter with the antenna extended at the distance mentioned above? The same results happen with all radio's and receivers.

Thanks

With my Futaba equipment I can get 150 feet with the antenna down and can have my 2 meter glider at the edge of where I can see it without problems.

Did you do this test indoors or out. Dennis

you really should do them where yu fly because houses and high lines, transformers and anything else metal can cause interference, i get different distances and reactions at my house than where i fly! IMO.

I wasn't as concerned with the chatter at 75 feet as I was with chatter at 350 feet with the antenna fully extended. It may turn out to be some stray interference in the area of my home since all of my radio's are acting the same way.

The receiver antenna being in very close proimity to the ground will reduce range substantially. Try putting your airplane up on a wooden table or ladder and your range should grow.

350 feet sounds pretty good to me if your airplane is sitting on the ground.

please look inyour manual and point out to me any thing about 300 feet. you are just making up things in your head that have nothing to due with range checking.

JPMacG,

Thanks for the comments. I believe your observation explains the situation since the Rx and servos are sitting on a platform that is only 6 to 12 inches off of the ground.

Thanks again
