International Lighthouse Lightship Weekend 2018


This weekend, 18-19 August, there was the 21st International Lighthouse Lightship Weekend, an annual amateur radio event held on the 3rd weekend in August since 1998.  

I tried to participate mainly on 14 MHz SSB, but propagation does not help

Here is my log:

Once more I noticed that many participants still append "/LH" or "/LGT" to their regular callsigns. This practice is not really compatible with electronic logbooks and, especially, with on-line logs like LoTW and ClubLog.

SW Radiogram over WRMI 7780 kHz





Tonight I managed to receive the Shortwave Radiogram digital transmission over WRMI - Radio Miami International on 7780 kHz using my Perseus SDR receiver and fldigi 4.0.17 by W1HKJ. The antenna is a trap dipole for the 40m and 80m bands.




The transmission began on July 22, 2018 at 22:30 UTC with a brief waterfall image and was followed by approximately 30 minutes of MFSK32 and MFSK64 text and images.

MFSK text reception was 100% error-free, while images were degraded by the high level of noise which affects reception at my location.

Still active: ROS network on 27635 kHz

Freebanders using ROS, heard on 27635 kHz
The digital freebanders' network on 27635 kHz (11 m), described in a post on 2017-04-06, remains active. The current (July 22) Es openning in Europe allowed strong signals into Greece from Maidenhead locator fields JN and JO. Stations in this extensive network use the ROS MFSK protocol calling CQ or transmitting beacons in various data rates (4, 8 and 16 baud). 

Fortunately PSK reporter supports 11m activities and allows plotting the stations on a map.

COMMON AND PRECIOUS on 6398.5 kHz


The beacon on the waterfall on my Perseus SDR

The COMMON AND PRECIOUS propagation beacon, which used to operate on various frequencies like 10237.6 kHz, recently recently moved to 6398.5 kHz. 

The beacon operates in CW and transmits the message: "JO62SK 52W DIPOLE JO62SK COMMON AND PRECIOUS". Yesterday evening it was received on my Perseus SDR with very good signal.

The string JO62SK is a Maidenhead locator centered at Aldershof, a German town southeast of Berlin.

Ham radio awards 8.1: DXCC on 50 MHz !

50 MHz DXCC #1558 - 2018-06-01


The 2018 Es season started with earning DXCC on 50 MHz (The Magic Band) on June 1, 2018. Since then I have worked a few more new entities so my current total is 105 worked, 104 confirmed. I am still waiting for a couple of direct QSL cards from Z3 stations before applying for endorsement.

The 50 MHz DXCC certificate arrived today, along with the "6 METERS" endorsment for the 5 Band DXCC plaque ! The 6m certificate will be my final DXCC achievement, as I am unable to operate on 160m, 2m or Satellite.
