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

Current Operating Frequency and Mode

OFF AIR but returning after dark on Saturday night

All around a weaker session – even domestic openings around North America were down a bit as strong storms in the Midwest make listening difficult; WH2XXP -> JA3TVF, JH1INM, VK4YB, and VK2XGJ trans-Pacific session highlight; Great JA and VK openings for WH2XCR

The details for April 10, 2016 can be viewed here.

The few lucky nights of quiet band conditions in April are over as a noisy storm system originating in the Midwest not only impacted transmitting stations in the region but also receive stations trying to listen for stations around North America.  I’m happy that I was able to take advantage of the quiet night on Friday.  Maybe there will be a few more.

It was also another noisy night in Oceania and early indications suggest that reports to and from the region may be even leaner than recently observed.

Geomagnetic conditions returned to quiet levels after some surprises during the previous session.  The Bz is pointing to the North this morning and solar winv velocities are averaging  near 435 km/s.  DST values took an optimistic turn to near positive values but the band seems to be depressed at the moment.  Solarham reports that the earth-facing solar disk is currently devoid of sunspots.




Andy, F6CNI, reported that he could lightly observe VO1NA’s CW signal on 477.7 kHz during this session but was only listening using a 1-meter long whip antenna inside the ham shack with his FT1000MP.  Andy also noted another signal on 477.718 kHz but the signal was never strong enough to make a determination of the call sign.

Roelof, PA0RDT, also reported Joe’s signal and indicates that propagation was a bit better.

Neil, W0YSE/7 / WG2XSV, was reported by Toby, VE7CNF, at 0225z while operating JT9.  Neil was reported at -26 dB S/N.  Neil indicated that Toby was  best at -3 dB S/N at his QTH.

There were no trans-Atlantic WSPR reports during this session.

Paul, N1BUG / WI2XTC, reported that QRN was low, transitioning to moderate as the session progressed.  He decoded seven WSPR stations.

Al, K2BLA / WI2XBV, reported that he was experiencing a high SWR this morning which turned out to be weeds with dew on them brushing against the base of the antenna.  Al reported that during his evening activity he decoded eight WSPR stations and he was decoded by 29 unique stations.

Rick, W7RNB / WI2XJQ, reported that the “Mississippi wall” had returned as band conditions were once again depressed.  He provided reports for nine WSPR stations and he was decoded by 18 unique stations.  Rick’s unique report details can be viewed here.

Dave, N4DB, reported that he decoded eight WSPR stations with WH2XXP being the only stations that was further than 3000 km away.  ZF1EJ, however, at a distance of 2021 km directly to the South, was reported at Dave’s Virginia QTH all night along.

Trans-Pacific reported details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, posted links to two tables showing VK/NA -> total JA DX  and VK/NA -> JA peak S/N for the session.

Roger, VK4YB, reported high QRN and difficult receiving conditions as well as no reports from VE6XH who appears to have been absent for the session for only the second time since he and Roger began their comparison experiment between 160-meters and 630-meters.  He adds that propagation was also mediocre.  Roger received reports from JA3TVF, JH1INM, WH2XCR, WE2XPQ, W7IUV, and WI2XBQ.  He provided reports for WH2XCR and WH2XXP.

Ward, K7PO / WH2XXP, received reports from 58 WSPR stations including VK4YB, VK2XGJ, JA3TVF, and JH1INM.

Joe, NU6O / WI2XBQ, reported that the band was depressed compared to recent sessions.  He provided reports for VK4YB and indicates that he was “…Heard by only 19, prop to the E shutdown, best DX XIQ, 2580km. Good single digit prop to XCR and stations to the N.”

Larry, W7IUV / WH2XGP, provided reports for ten WSPR stations.  He was decoded by eleven unique stations.  As W7IUV, Larry provided reports for eleven WSPR stations including VK4YB.  He indicates that bad weather in his area cut his operating time short.

Noise was clearly elevated through this session due to storms to the North and Northeast.  This was definitely not a CW night, however.  Propagation seemed a bit down but its unclear whether this was only my perception due to elevated noise.  Transmission numbers were “good” but down a bit from the previous session.  Those report details can be viewed here.  My reception numbers were also down but I will blame the noise for that. Those report details can be viewed here.  Two-way reports with WH2XCR were quite good and was probably the highlight of the session at my station.  Strong storms are expected for a few days starting this afternoon so I may be QRT for a few days.

Eden, ZF1EJ, provided reports for seven WSPR stations and he was decoded by seventeen unique stations.  Eden shared two-way reports with WH2XCR.

Laurence, KL7L / WE2XPQ, has ended his activity in Mexico and is returning to Alaska.  He provided this parting shot of his accommodations and asks if anyone can spot the E-probe:

As WE2XPQ back in Alaska, Laurence provided reports for VK4YB and shared two-way reports with WH2XCR.  Propagation has generally been considered to be  down overall compared to previous sessions but Laurence experienced a relatively nice night of reports along the West coast.  He also appears to be hearing well which may be attributable to the significant improvements in DST.  Laurence also noted that he allowed the transmitter to run for one hour after sunrise in Alaska to test late openings to which there were none observed.   DX report details can be viewed here.

Merv, K9FD/KH6 / WH2XCR, experienced a pretty strong session, sharing two-way reports with VK4YB, WE2XPQ, and ZF1EJ and received reports from 7L1RLL4, JA1NQI/1, JA3TVF, JH1INM, JH3XCU, and VK2XGJ.  North American coverage was generally limited to the central and western areas but K3RWR / WH2XXC also provided reports for Merv.  He may also have been experiencing Internet problems as he disappeared from the WSPR map on the lead-up to sunrise, returning only when reported by a station.  This problem could also mean that stations that Merv might be hearing may go unreported to the WSPRnet database.   DX report details can be viewed here.
