Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

Probably QRT tonight and in the morning due to storms in the area

Incredible night of trans-Pacific openings as WH2XXP reported at VK6LX at a distance of 15447 km; Unsettled geomagnetic conditions may be on the horizon again; VK4YB finds workable compromise as he works to repair damaged antennas; Noise remains a big problem for much of North America but changes are coming

The details for August 12, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet. That includes stations using fake or pirated call signs. 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.

Many stations reported very high QRN even early in the session and that considerably impacted activity and reports.  Expect more of the same in the coming days.

11-hour North American lightning summary


Geomagnetic conditions reached elevated-quiet levels as Solarham indicates unsettled conditions are possible in the coming days. The Bz is pointing strongly to the North this morning and solar wind velocities are elevated to moderately high levels, averaging near 590 km/s and trending higher.   The bottom has not yet dropped out of DST values but instability is noted.




Neil, W0YSE/7 / WG2XSV, reported that he was operating in a receive-only capacity during this session using his E-probe.  His session best reports includeVE7BDQ at -14 (John was at 0.5w), VE7CA at -4 with 1w, WD2XSH/26 at -25, WG2XXM at -21, WH2XCR at -23, WH2XGP at +11,  WH2XXP at +5, and WI2XJQ at -5, all reported in dB S/N at standard WSPR bandwidths.

David, N1DAY / WI2XUF, reported that “Last night seemed like a return to what I would expect propagation-wise this time of year with spots occurring much later at night than the previous several sessions.  I heard 8 unique stations and 18 unique stations heard my signal.  Early on, I was concerned that recent changes to my antenna system with conversion to a mix 77 impedance transformer and correction of several ‘less than linear’ sections of the horizontal elements of my Marconi Tee may have had a negative impact on my TX/RX performance, but this appears not to be the case.”

Rick, W7RNB / WI2XJQ, provided reports for ten WSPR stations and he received reports from fourteen unique stations.

Mike, WA3TTS, reported that he decoded ten WSPR stations overnight “with NW EWE antenna and dual band operation with hybrid splitter on IF output of converter.”  Reports include:

“WH2CXR  1 decode @  0940 -27
WH2XGP 21 decodes, best -14 @ 0856  min -27
WH2XXP  70 decodes, best -7,  min -25
ZF1EJ       3 decodes, best -26, min -30
WG2XIQ    2 decodes, best -22 min -24
WD2XH/15 7 decodes, best -21, min -27
WI2XSV   60 decodes, best -4   min -28
WI2XUF   78 decodes, best -9   min -28
WG2XJM  49 decodes, best +12, min -30

Mike added:

“Interesting that both Eric XJM and I had single XCR decodes at slightly different times and close SNR values for our relative locations…

09:40   WH2XCR     0.475618     -27       0       BL11je       1       WA3TTS       EN90xn       7439       54
09:56   WH2XCR     0.475617     -30       0       BL11je       1       WG2XJM     EN91wr       7413       52

Also 49 WH2XND decodes, best -21 @ 0936 (very close to XCR decode time on 630m) and min -33 at 0448…”

Hideo, JH3XCU, submitted this link detailing DX -> JA decode totals and DX -> JA S/N peaks for the session, as reported on the Japanese language 472 kHz website.

Roger, VK4YB, received reports from E51WL, VE6XH, VE6JY, VE7BDQ, JH1INM, N6GN, W7IUV, WE2XPQ and WH2XGP. He shared two-way reports with WH2XCR.  Roger has also won the war and signed an armistice with one of the trees that he has been fighting.  He explains:

“I attached an old boat winch to a near-by tree and just kept turning the handle until something broke.See photo. I was very lucky. The wire broke just a few inches from the join with the dacron line. I was able to recover all of the dacron and most of the wire. I tried twice more for a high branch but in the end I had to compromise and use a stronger lower branch. Result is the NE beam is back but the main vertical section is now only 80 feet high, At least it is likely to stay there because there is not much movement at that height, whereas the top-most branches thrash around in a gale. I think the receive performance will be much the same, but I reckon I will lose a dB or two on transmit.”

Zim, VK3GJZ, reported WH2XCR and WH2XXP and submitted this capture to the VK/ZL 600m reflector:

Ken, K5DNL / WG2XXM, indicates that he had to shut down early due to approaching storms and subsequent high QRN.  He provided reports for six WSPR stations and he received reports from 37 unique stations including VK4YB, WH2XCR, ZF1EJ, and five Canadian stations.

Ward, K7PO / WH2XXP, reported a great night with WSPR decodes of his signal that continued from VK4YB until at least fifteen minutes after sunrise in Arizona.  Those reports began at 0718z.  Ward also received reports from VK6LX in western Australia at a distance of 15447km.   He received reports from fifty unique stations including E51WL, EJTSWL, VK2COW, VK2EIK, VK2XGJ, VK3GJZ, VK3HP, VK5AKK, VK5FQ, VK5ZVS, VK6LX, ZL2BCG, and VK4YB.

Larry, W7IUV / WH2XGP, provided reports for eleven WSPR stations and he received reports from 33 unique stations including E51WL and ZL2AFP.  He shared two-way reports with VK4YB. As W7IUV, Larry provided reports for ten WSPR stations including VK4YB.

Thomas, DM4TR, posted this link on the RSGB-LF reflector for a new digital phone software package apparently designed for use at MF and LF.  I’ve not fully read through the details yet (in German) so I’ve not yet determined what the emission designator is but even if no current operator’s grant allows the modulation scheme at this time, it may be worth keeping in mind in the future.  I would expect this mode utilizes significantly less bandwidth than traditional phone modes.

I had best intentions, planning on beginning 630-meter activity in the late evening after playing a bit in the WAE contest on HF and a little operating on 160-meters but unfortunately a cold front fired up a few storms across my area and just as quickly as one ended, another one began.  I was able to briefly make a few WSPR transmissions, receiving reports from the upper Midwest, New England and the Southeast before QRTing again for the night as new storms flared up.  It was VERY noisy here in North Texas  but I expect things will begin to improve over the next month or two.
