Intruder dashes on 29679.9 kHz, Dec 17, 2014
« on: December 17, 2014, 1634 UTC »
For the last couple days I have been hearing dashes on about 29679.9 kHz, the frequency does appear to move around a little.  I first noticed them about 2300z on Dec 16, and they are still up right now, 1530z Dec 17.

The dashes appear to be spaced about every 2.35 seconds, and they are roughly seconds 0.46 seconds long.  There is either some kind of modulation on the first 0.06 seconds of the pulse, or it takes the transmitter that long to settle.  About 0.06 seconds further into the pulse (roughly 0.12 sec from start) there is a further glitch.  The pulse is stable for the remaining time it is on, about 0.32 sec.

These dashers are still on air, apparently 24 hours a day, 7 days a week.  Since it is in the ham band, and near a repeater frequency, I am surprised there is not more mention of it on the web.
