I do not know where Kaoma got his info but hope you all ignore it. He would benefit from dragging out a text book or two and doing a little reading.
FYI:
Electronics/HS (radio), Communication-Satellite Communications/College, "WABC" and "Hard Copy Show" Communication BoomTruck, RF Eng. & Field Opperations for a national Communication Co. to name only a few...
Now, what are your credentials???
MY Tx radio test as soon as I bought it: (JR 8103 FM Air)
-NiMH 1850 AA pack fully charged
-Tx radio turnd ON with antenna collapsed
-placed radio in the microwave (isolation box-microwave OFF) for one hr.
-took radio to work and hooked it up to the HPSpectrum Analizer
The Tx radio was right on the dot reading 72.490 (Ch. 35) outputing 675 mW.
Any Futaba owners dare to do this???
The antenna must be UP for the wavelenght reasons ant NOT because you would risk to fry the Tx. On the other hand the telescopic antennas are the worst type anyway.
Here is my .02
(there is so much ignorane about the RF that I gave-up explaining. If you see any guys at the field flying in barefoot...I was the one who told them...)
