Mem
ber of DARC in local group K19. QTH: Meisenheim, locator: JN39ur
Most time QRV on ten meter band, observing 10 meter amateur radio beacons (daily reports to the HF beacons group)
and fishnet buoys (monthly report to the german Bandwacht) and storing the results as records using HAM Office.
Look
ing for Aurora conditions, too, logging DL0IGI on 28.205 MHz, antenna direction: 30° (North-East).
 
Logging the beacons with the program SPECTRUM Laboratory (similar the ARGO) of DL4YHF I create sonagrams and diagrams of the fieldstrength.
Fieldstrenght is indicated below in diagram. By division of fieldstrength (on the right-hand scale) by ten, an approximate S-value is obtained.

Examples:
Sonagrams:

I1YRB:
10 meter QRPP beacon from Italy, listed at 20 August 2008 via Sporadic E-Layer. Frequency is 28.322 MHz.
Suddenly at 13:31 UTC the beacon signal appeared, fieldstrength was growing up to 599+30 at 13:34 UTC, and fading out at 13:52 UTC.

ER1TEN:
10 meter Moldavian Beacon, frequency 28.2488 MHz, on 24 July 2009 via ES.

Spreadsheet of Beacons heard during a day :
The charts are created every day after storing into HAM Office in the late evening.

Only for Beacon Gurus :
There is a beacon spotter website for spots and chats, created by KC4TM (ex KI4KQQ).
