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

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

PA0A -> UA0SNV returns; more solid openings on trans-Atlantic paths; Trans-Pacific paths continue to show attrition; Very high band activity overnight

– Posted in: 630 Meter Daily Reports, 630 Meters

The band was in very fine form in spite of precipitation static and noise from holiday lights for some.  Long haul and domestic openings were plentiful for a number of stations.  The good news is that the limited number of thunderstorms in North America did not last for long.

Geomagnetic conditions continue at very quiet levels although the Bz is currently pointing slightly to the South with proton levels elevated to the moderate category.  Solar wind velocities remain low, averaging 360 km/s.  DST values continue in positive territory.







The very long haul path between PA0A and UA0SNV returned for this session with several reports for Albert’s signal.  Report details can be viewed here.


PA0A, as reported by UA0SNV


Trans-Atlantic paths were strong again as VE9GJ provides reports for F1AFJ/1 and G8HUH.  WG2XXM received reports from F1AFJ/1, F59706, and G3XKR.  WG2XKA received reports from G0LUJ-1 and the sole trans-Atlantic reports from LA2XPA.  WD2XSH/17 did well, reporting F1AFJ and G8HUH and receiving reports from DL-SWL, F1AFJ, F1AFJ/1, F59706, F6GEX, G0KTN, G0LUJ-1, G3XKR, G8HUH, and PA0RDT. Report details for these stations can be viewed here.

John, WA3ETD / WG2XKA, provided these additional comments:

“Totally frozen ground and subzero temps forced a massive retuning operation here at XKA  Last session was run at about 120W TPO due to gusting winds.  However, it was enough to be heard by LA2XPA on the high latitude path .. the PNW was also well represented with several both-way exchanges.  I have no complaints about conditions in general as most of the usuals were active.  XKA was also heard by WH2XCR and G0LUJ-1.”

Ken, K5DNL / WG2XXM, reports that he was decoded by 66 unique stations including WE2XPQ, WH2XCR, F1AFJ/1, G3XKR, and F59706.

Doug, K4LY / WH2XZO, raved about the amount of activity as he provided reports to eleven WSPR stations and was decoded by a record 51 unique stations.  Doug adds, “…nothing unusual, just great activity!”

Neil, W0YSE/7 / WG2XSV, reported  that he was decoded by 22 unique stations  while operating at 1-watt ERP during this session.  He also received two decodes from ZF1EJ/1, and he decoded WH2XZO three times.  Neil adds that “…conditions must have been pretty good from Vancouver WA.”  Neil explains his power decrease:

“I am back to 1w ERP because I had some 120 hz modulation on the extra 6 volts that was in series with my normal supply. Need some heavy filtering on the 6v section before going back to 2w EIRP. Some of the guys who were getting strong decodes on my main frequency were also getting another exactly 120 hz below that.”

Neil also added that early in this session, just after local sunrise he had success at longer haul JT9 reports.  He indicates that these openings often remain until near local noon:

“Just playing with JT9 about 10 minutes after sunrise. Got this report from PSKreporter

Rx at Fri, 16 Dec 2016 15:56:50 GMT
From WG2XSV in United States
Loc CN85rq by VE7CNF
Distance: 399 km bearing 176°
Frequency: 0.475.446 MHz (600m), JT9, -19dB

Looks like Toby and I could have had a QSO on either JT9 or WSQ2, but not quite on MFSK8…interesting possibilities….”


Rick, W7RNB / Wi2XJQ, reported at least six new receiving stations during this session, receiving decodes by 34 unique station and providing reports to seven WSPR stations.  Rick’s unique report details for this session can be viewed here.

Trans-Pacific report details for this session (excluding KL7 and KH6) are aggregated here.

Roger, VK4YB, reports “More fading than usual tonight. Some signals up to -15 S/N but fade to nothing within the 2 minute slot. Good path to Japan. TP spots are down but some stations are missing.”  Roger received reports from WE2XPQ, 7L1RLL4, JA1NQI-2, JA1PKG, JA3TVF, JE1JDL, and JH3XCU.  He provided reports to WH2XGP and WH2XXP, and shared two-way reports with VE7BDQ and WH2XCR.

John, VE7BDQ, shared two-way reports with Roger, VK4YB.

Ward, K7PO / WH2XXP, received reports from 63 unique stations including VK4YB and VK2XGJ.

John, VK2XGJ, reported WH2XXP early in his reporting session:


WH2XXP reported early at VK2XGJ


Larry, W7IUV / WH2XGP, provided reports for fourteen WSPR stations and was decoded by 58 unique stations, including VK4YB and ZF1EJ.  Larry indicates that the western receive antenna, designated as W7IUV on WSPR, has been damaged and may be down until further notice.

Mike, WA3TTS, reports, “All iced up here, waiting for higher temps this afternoon. atmospheric QRN was S7 range much of last night”

I was not transmitting for long during this session due to high winds.  I suspect the same may happen this evening.  I started the session with CW and the band sounded great.  I thought I heard a few “tuner-uppers” but they may have just been WSPR harmonics as there was no response to my QRZ.  WSPR reports were typical, very good and strong into the usual areas early in the evening.  There was no CW session this morning.  Curiously, my reception and transmission report numbers flip-flopped for this session, with more than a 1000 reception reports and only about 620 transmission reports for four hours of operating.  My WSPR transmission reports can be viewed here and my WSPR reception reports can be viewed here.


WG2XIQ 24-hour WSPR activity


Activity was very high but I did not take a census during this session. KB3WOE, VE3XZT, AE5JG and KB4JMT were receiving for what may have been their first time on 630-meters.  KB4JMT, however, may have been listening on the old, inactive frequency of 503.9 kHz, which is the default in WSPR version 2.x.  If anyone knows this operator, please direct them to this blog post for details on the updated frequencies.  Welcome aboard!

Eden, ZF1EJ, briefly operated two stations, with ZF1EJ reporting WG2XIQ, WG2XXM, WH2XGP, WH2XXP, and WH2XZO.  Report details for these stations can be viewed here.  As ZF1EJ/1, Eden reported, VE3CIQ, VE3EFF, VE7BDQ, WD2XSH/15, WD2XSH/17, WG2XIQ, WG2XKA, WG2XSV, WG2XXM, WH2XCR, WH2XGP, WH2XXP, WH2XZO, and WI2XJQ.  Report details for these stations can be viewed here.

Laurence, KL7L / WE2XPQ, experienced a nice turn around after returning the station back to working order after recent weather damaged.  He reported VK4YB and shared two-way reports with WH2XCR during this session.  Those report details can be viewed here .  UPDATE:  Laurence indicates that the PA tripped off around 0642z, probably due to a moose incursion.  He will inspect at first light for damage.  He adds that the driver shut down at 1306z.

Laurence also reported yesterday that the main E-probe was down due to high winds and he provided this picture.  Apparently the probe continues to hear stations in the lower-48 from ground level.

Merv, K9FD/KH6 / WH2XCR, returned for this session, sharing two-way reports with VK4YB and WE2XPQ and receiving reports from ZF1EJ, 7L1RLL4, JA1NQI-2, JA1PKG, JA3TVF, JE1JDL, and JH3XCU.  Merv also decoded WG2XKA and WH2XZO in the eastern US.  Report details for these stations can be viewed here.
