M0AYF has a great bunch of information about QRSS operation. It’s really good stuff: filters, antennas, frequency standards, receivers, you name it! Very, very cool. Worthy of reading and constructing.

Testing New S/MT Hellschrieber Beacon ID…
I am currently running my 2w beacon with the following sequential multi-tone Hellschrieber ID on 30m:
As Colin, G6AVK pointed out, this is likely to be a lot less effective than my previous MV identifier, but if it does work, people might have a better chance of knowing who the beacon actually is. I’ll let it run for a while and see how it does. Propagation is falling off a bit for me now, but might get better later.
11 Hours of 30m Beacon Band…
Well, last night, I tweaked my recording program to produce recordings in 15 minute chunks and started it running. This morning, I had a bunch of recordings, a short run of which produced the following spectrograms (never tried this WordPress functionality before hope it works out!):
Addedum: Sigh. WordPress insisted on converting my nifty names (which told you what time they are recording) to shorter things, which didn’t preserve their relative ordering. Grump. Oh well. I think I got them sorted. By hand. How tedious.
Addendum2: Here’s W8LIW’s beacon, booming in quite strong.
