No modulation from sstran

Posted on June 6, 2009

As you all know storms have been popping up all over the U.S. in the past 2 weeks. Kentucky alone has had three or four days of rain/thunderstorms with cloud to ground lightening.

As you all know storms have been popping up all over the U.S. in the past 2 weeks. Kentucky alone has had three or four days of rain/thunderstorms with cloud to ground lightening.

Well ive been running the sstran on the short wire antenna that came with the kit and the range was limited to the inside of the house and about 20 feet outside.
It was not intended to cover more than that since i wasn’t ready to mount it outside. I was just using it to listen to different programming provided by a mp3 player set on shuffle.

When i pulled in i noticed a carrier with no modulation on 1520 khz.
I just figured the battery had died in the mp3 player and would replace the battery next time i wanted to listen to something different than what i play on 1700 khz. I just shut off the sstran and went about my business.

Today i fired up the sstran and the mp3 player and noticed the modulation was low, really low. I checked the player and the controls on the sstran, i even plug in a patch cord from 1700 khz to see if the problem was the player or the audio cable.

Unfortunately that didn’t fix the problem. I have the same carrier i had before I lost modulation. So something must have popped while i was away from home.
I am wondering if lightening might have had something to do with the sudden loss in modulation or perhaps something i did, maybe bad soldering on my part.
Anyways, ill be tearing into that when i find the time, it couldn’t be much. Could it?

Before i go, the modulation is just barely audible and if you crank up the gain, modulation you get a fuzzy sounding noise.
With all the controls turned off i get a clear hum free carrier.
