After having lots of trouble with planes being shot down at our field we go a tester from the ama to check if someone is interfering with us. Sure enough there is, but trying to get some help is imposible no one will help us resolve this, FCC told us there is nothing they can do and the AMA will not return our calls. So whats the deal are we just spose to lay down and let the train run us over and over again. We are now limited to only 2.4Ghz at our field and our members with 72mhz are out of luck. From what we understand the 72mhz that we run channel 11-60 were sold out and no one every informed us this Did i miss something but wasn't the Ama spose to protect these and if they couldn't I believe we should be aware before some on gets hurt or worse killed!!! Any suggestion would help out greatly we have been at the same field for 25 years and would hate to leave. We are not sure if the sell out thing is true but it would be great to find out the real truth of the matter. Hope to hear from someone........Twostroke.
