Another night of curiously strong band conditions on 630-meters. During the evening I noted that most signal had a smudged appearance in the waterfall, where the signals lacked clearly defined boundaries. WSPR signals were decoding with no problem and signals were all generally very strong with a low noise floor which improved as the evening progressed. Perhaps this is an artifact of the geomagnetic activity that has been in progress. Solar wind continued to peak of 600 km/s through much of the session but at the time of this report’s development during the noon hour on Tuesday, the solar was in down to the mid-500 km/s range. The Bz component generally ranged from + / – 5 nT through the session.
The Kyoto DST was generally stable, remaining slightly negative. Perhaps this stability is a testament to the success experienced by WH2XCR through the session with solid, persistent reports to both JA and VK.
John, VE7BDQ, Toby, VE7CNF, and Neil, W7IUV / WH2XGP, had some fun with MFSK16 during the evening. Toby was sending pictures which I did not know was possible with MFSK16. Neil reports that the group was using FLDigi to send and decode and John, noted that MFSK16 often does better than traditional SSTV. Even more important is that the mode does not require a linear amplifier. Details on MFSK in FLDigi can be found here. Here are a few screen shots of Toby’s transmissions from Neil and John:
What’s remarkable about the last shot is that even with the noise, Neil was able to receive enough of a signal for a QSO had reports been exchanged. I inquired about the S/N reported during this transmission but Neil did not know. The signal is still quite serviceable. This is a mode that I will have to try sometime. I had no idea that it could function as more than a keyboard-to-keyboard mode.
Also active through this session was Paul, W0RW / WA2XRM, who was operating QRSS30 again. There has been more discussion about the frequency instability but the “RW” signal is easily decoded visually in the screen shot below from Jim, W5EST.
WSPR activity dominated the session, with 86 MF WSPR stations reported at 0300z on the WSPRnet activity page. The continental and regional breakdown follows:
Trans-Atlantic activity was high once again, with John, WA3ETD / WG2XKA, being reported again by G3XKR, and Mike, WA3TTS, reporting Stefan, DK7FC with his reversible EWE receive antenna system located on a suburban lot.
Mike, WA3TTS, posted this description of his receive antenna system and screen shot of his console on RSGB “Blacksheep” reflector:
The trans-African path from Europe to Reunion Island was open to only one European station last night, SV8CS:
In the Caribbean, Eden and Roger report most of the active usual suspects:
In Alaska, Laurence, KL7L / WE2XPQ, had a slightly better night as auroral activity tries to settle down. It will likely take several calm sessions before the possibility exists for activity to begin looking normal again, at least by 2015 standards.
In the Pacific, Merv, K9FD/KH6 / WH2XCR, had a strong session with persistent reports from two JA’s and one VK station.
John, VK2XGJ, sent a screen shot of his console from the session showing Merv’s reports:
Phil, VK3ELV, continues to receive reports from JA, which I believe is important in the continued success of reports for Merv in VK as we progress towards summer in the southern hemisphere.
Other anecdotes and statistics:
Doug, K4LY / WH2XZO, indicates that he had 225 reports with positive S/N values that were over 600 km away, with the best being +11 db S/N from W9HLY and WH2XRR. Doug interferes from this that he has a lot of high angle component.
I’ve been absent for a few days from my morning CW session for a variety of reasons but hope to get back to a routine shortly.
