Pre dawn, a tune around the beacons, March 13, 2015
« on: March 13, 2015, 1750 UTC »
I have not been paying much attention to the beacons recently.  Sure I see them as I tune around, but not really taking note.  A few of the old friends are gone, and one or two new ones appear to be there.  So this morning I took a little look.

These are the ones noted pre local dawn, I will do a separate post on the post dawn beacons seen.

- 2016.73 kHz, 1352 UTC, ditter, dit is about 0.16 sec long and occurs about every 0.88 seconds.  I have been seeing this one for a while, but I am not sure it has ever been reported here.
- 2018.26 kHz, 1352 UTC, ditter, dit is about 0.22 sec long and occurs about every 1.25 seconds.  Cycles on and off, about 2 mins on for 5 mins off, but this may vary.
- 2097.3 kHz, 1359 UTC, A beacon.  Sends letter A in CW about every 10 seconds.
- 4094.5 kHz, 1403 UTC, X beacon.  Sends letter X in CW about every 7 seconds.
- 4096.27 kHz, 1405 UTC, dasher, Hexie, dash is about 1.13 seconds long and sent about every 2.19 seconds.
- 7998.2 kHz, 1346 UTC, dasher, dash is about 0.65 sec long and occurs about every 3.1 seconds.
- 13559.95 kHz, 1407 UTC, ditter, dit is about 0.050 seconds and sent about every 1.09 seconds.  Dit has rough ending that might be 2 shorter dits, so this could be sending the letter D in fast CW.  Has been active for some time, but not sure if reported here.

Thanks for the great benchmarks on reception. I am hearing the 13 MHz beacon at 13,559.863 KHz

EDIT: After 57 dits it momentarily transmits a close double dit at 58 dits, the 60 second mark
