The details for July 14, 2016 can be viewed here.
IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet. Please continue to be patient and let the FCC finish their processes. UPDATED: Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.
Noise continues to be a major feature impacting listening and the associated storms are no doubt making activity difficult for some operators. Noise is a common feature for July so none of this is abnormal. The level of persistent storm coverage seems to be, however. Daily storms are forecast to return here starting this weekend for the coming week. Propagation was average to below average again. Some areas may have fared better than others.
Geomagnetic conditions were quiet, in fact the stability was better than conditions observed in quite a while. The Bz has also been stable and has remained very close to the centerline. Solar wind velocities are averaging near 350 km/s and DST values continue to show a lot of stability, generally at positive levels. A long duration M-class flare with an probable associated CME was observed last evening.
Dick, W7WKR / WD2XSH/26, reported that he has returned to air after some time away. He is using an Apache Labs ANAN-200D SDR which is apparently capable of nearly 17-watts TPO on 630-meters and is adjustable in the software up to the hardware’s limit. As far as I know this is the highest 630-meter output of an off-the-shelf rig that is currently on the market. Dick indicates that the output is a reasonably good sine wave but probably could benefit from additional low pass filtering. His antenna is a sloping 160-meter half-square that is almost a quarter wave in total length and he uses a series LC network to adjust.
More discussions with Murray, ZL1BPU, have uncovered a very free and easy approach to MF, LF and VLF activity in New Zealand, including an amateur allocation from 130-190 kHz and no questions asked. He indicates that their communication authority allows up to 25-watts ERP on 630-meters and up to 6 kHz modes. He added that there are currently about seven active stations in New Zealand and he is making a push for additional activity. Showing just how much isolation there can be in Oceania, Murray reports that he normally only hears VK4YB at his station in spite of significant additional activity from VK. I’ll report additional things from New Zealand as I continue to work my way through some of the communications that I have had with Murray.
Ken, K5DNL / WG2XXM, reported that he decoded four WSPR stations through QRN and he was decoded by 32 unique stations including E51WL, WH2XCR, ZF1EJ, and six Canadian stations.
Neil, W0YSE/7 / WG2XSV, reported more success with FT8 and he submitted these comments and statistics:
“I decoded 6 wspr stations this session. Got 3 of Merv/XCR and 6 of Laurence/XPQ, along with several of the others which include XXM, XXP, XSH/26, and XGP.
Dick, WD2XSH/26, was able to decode my FT8 very well with a best of (apparently) -4 dB, as seen in a screen shot he sent me last evening. I was not able to decode His FT8 however, but we might try JT9 next time since his WSPR was bouncing between -20 and -30 during the 9 o’clock hour that we try to work each other (04z-05z).
My WSPR was decoded by 19 unique stations this session, including XPQ, XCR, 2 Alberta stations, and Mark in Utah. This is the most unique reports I have had in one night for probably about 2 months !! Participation was high all up and down the western states and provinces.”
Trans-Pacific report details, excluding E51, KH6, and KL7, can be viewed here.
Ward, K7PO / WH2XXP, received reports from 37 unique stations including E51WL, VK4YB, and ZL2AFP.
I started the session with CW at 0112z, calling CQ on 474.5 kHz. Eric, NO3M / WG2XJM, noted after dark that he was hearing bits of my signal. He made a few transmissions using the “triple-decker vintage field day rig” for which he just completed winding 630-meter coils. The transmitter is outputting about 130-watts at 66% efficiency and a few other mods have improved the stability of the system overall. Unfortunately his signals was mostly ESP here during this session as I was listening due East to minimize noise. A bit of WSPR after the CW session suggests that the band was flat early in the evening, in fact, there remains a glow on the horizon at 10 pm local time here. I intended on getting up early to get on the air but I was late so this activity did not materialize today.
Regional and continental WSPR breakdowns follow (note that the North American map has been excluded due to massive data pollution from a station in the Desert Southwest):
Eden, ZF1EJ, provided reports for two WSPR stations and he received reports from four unique stations.
Warwick, E51WL, provided reports for nine WSPR stations split between Oceania and North America. Report details can be viewed here.
Laurence, KL7L / WE2XPQ, indicates strong storms in Alaska but he provided reports for three WSPR stations and he received reports from ten unique stations. He shared two-way reports with WH2XCR.
Merv, K9FD/KH6 / WH2XCR, provided reports for VK1DSH, VK3HP, VK5FQ and ZL2BCG. He shared two-way reports with WE2XPQ and VK4YB and he received reports from E51WL, VK2XGJ, and ZL2AFP. Merv’s DX report details can be viewed here.
