Now you're Talking

A SEVERE CASE of interference surfaced in Houston, Texas on RC channel 57. Several large, expensive models were lost at a number of fields. Paul King obtained the RC Channel Analyzer from the District VIII frequency representative and started looking for the culprit without finding the RF interference. When two Hams, Bob McDonald and myself, heard of the problem and the availability of the AMA Channel Analyzer, we volunteered to assist. The AMA Channel Analyzer (made by Aero Spectra) is a hand-held unit the size of a large calculator, run by a nine-volt battery, which makes it completely portable. It only covers one band (71.9-73.1 Mhz). Editor's note: Newer models cover 50, 53, 72, and 75 MHz.
