Chirpy dasher 13556.38 kHz
« on: October 10, 2023, 2342 UTC »
Chirpy dasher, about one per second but inconsistent in keying times. Seems to be struggling to start each key up, unstable oscillator or low voltage maybe. Stops for several seconds at a time and comes back a bit lower in frequency then moves back up gradually. 10OCT23 23:33z

Chirpy dasher is back in there, not as chripy but still inconsistent timing. Some dashes longer than others and timing between dashes is variable. It has drifted to 13556.30. Airspy HF+/60 ft longwire E/W. 12OCT23 16:50z.

Weak but just came peeking up above the noise floor through the CODAR, heavy fading, same inconsistent keying. 14OCT23 23:14z

Chirpy dasher is back this morning with its inconsistent dashes. Some long, some short, timing varies. With all of the artifacts that are in the 22 meter ISM band it could be something other than a beacon but it does not seem to have any sort of modulation and seems to be struggling to transmit. 13556.47 KHz 22NOV23 18:50z Airspy HF+ Discovery 60ft SE/NW longwire
