12 and 10 meters open again

The summer is almost over and we are heading towards the equinox and the CQ WW RTTY contest. As always by the last weekend of August MUF increases and the first F2 layer openings on 28 MHz re-appear traditionaly during the SCC RTTY contest.

Today there was an opening on 28 MHz and I worked in RTTY during the contest the following stations: OH1VR, LY6A, F6GCI, EO26U, UW1M, DH8BQA, S53R, OK1CT, IU2FGB and RC5Z. 

Afterwards I switched to 24915 kHz FT8 and worked F4FSY, S57TW, R7AG and 9A5N. Now this was my very first QSO with Croatia (9A) on 12 m. Also I have never received LoTW confirmation for the few QSOs I have had with Slovenia (S5), so I wait for two new ones on my 12m DXCC.

SW Radiogram, August 26, 2017


After two weeks of no propagation, today at 16:00 UTC I received, once again, this weekend's Shortwave Radiogram on 9400 kHz AM. The transmission by Radio Miami International used the transmitters of Space Line in Bulgaria.





The digital modes transmitted in the TX audio were MFSK32 and included no less than 10 images showing aircraft of defunct US airlines. 






I used my Icom IC-706 MkII with a dipole antenna tuned for 3.5 and 7.0 MHz and a MFJ-969 antenna tuner. Decoding software is FL-digi 4.0.9.8 under Windows XP. 
Text reception was good, but not 100%, with occasional garbled charaters especially in the first 10 minutes of the transmission due to QRM.




The images were also received successfully with some deterioration due to co-channel voice interference in the case of the PanAm and TWA photos.

I sent an email with my reception reports to radiogram@verizon.net  right after the transmission.

International Lighthouse Lightship Weekend 2017

This weekend is the annual International Lighthouse Lightship Weekend, held on the 3rd weekend in August since 1998. 



I tried to participate, but propagation was really very poor, especially on Saturday. I managed to work very few stations, as shown in the extract of my log:

2017-08-19 15:12  14131.0  USB  GB2LBN   UK0034
2017-08-19 18:24   7149.0  LSB  DA2017LH DE0008
2017-08-20 06:16  14270.0  USB  TC1LHW   TR0002
2017-08-20 08:33  18153.0  USB  3Z2LS    ARLH POL017
2017-08-20 09:16  18163.0  USB  HB9ILLW  CH0004
2017-08-20 14:32  14260.0  USB  GB2BH    UK0180
2017-08-20 14:57  14205.0  USB  IQ3TS/LH IT0011
2017-08-20 16:27  14226.1  USB  IT9OPR   ARLH ITA153
2017-08-20 16:55  14265.0  USB  GB1OL    UK0195
2017-08-20 17:00  14192.0  USB  DA2017LH DE0008

I noticed that some stations had not registered with ILLW and were passing only their ARLHS world list number. 

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

I hope that I receive a few nice QSL cards via the bureau and that propagation is better in the ILLW 2018.

SW Radiogram, August 5, 2017

Today at 16:00 UTC I received, once again, this weekend's Shortwave Radiogram on 9400 kHz AM. The transmission by Radio Miami International used the transmitters of Space Line in Bulgaria.

The digital modes transmitted in the TX audio were MFSK32 and MFSK16, and included 5 images. 

I used my Icom IC-706 MkII with a dipole antenna tuned for 3.5 and 7.0 MHz and a MFJ-969 antenna tuner. Decoding software is FL-digi 4.0.9.8 under Windows XP. 

Text reception was good, but not 100%, with occasional garbled charaters due to QRM. Mode switching between MFSK32/16 was done automatically.

The images were also received successfully with some deterioration due to co-channel voice interference.

I sent an email with my reception reports to radiogram@verizon.net  right after the transmission.
