Big Talker Tune Up
Posted on November 29, 2011
Since the two AM transmitters and antennas just got a very complete tune up, with the new AMT5000 and all, it was time to check out Big Talker, the shortwave transmitter at 13.560mHz. It has been running everyday since being built but I checked it out and re-adjusted the power.
I backed off the modulation a bit, since the audio quality is so crystal clear it sounds like an FM station, and I don’t want those highs to splatter too much.
The power is set at 495mW, which is high, but since the antenna is still indoors I doubt that it matters very much.
Once the antenna is outdoors I’m backing down to PhilB’s recommended 45mW.
