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

Geo-effective coronal hole brings unsettled conditions and terrestrial storms impact activity in the East; A few transcontinental openings observed in spite of band conditions and WH2XXP -> VK4YB -> JA1NQI/2, JA3TVF paths open; Experiment between VK4YB and VE6XH comes to seasonal end and 630-meters fares surprisingly well

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for June 16, 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.  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.

There is a rumor that has been circulated somewhere on the Internet that claims to allegedly know the UTC notification procedures.  These rumors are lies and seriously jeopardize this process! DO NOT CONTACT UTC TO NOTIFY THEM OF YOUR INTENT TO OPERATE on 472 or 137 AT THIS TIME!  Official procedures are forthcoming – please be patient.  If you find a website or social media post that is perpetuating this bad information, please let me know so action can be taken to rectify the problem.  We can still screw this up!

FEDERAL REGISTER PUBLICATION OF FCC 17-33 which created the 630-meter allocation in addition to rules for both 630-meter and 2200-meters has occurred.  This does NOT mean that the band will open under part-97 rules in less than 30-days rather it represents another benchmark in the overall process.  We still await a “sign off” from OMB to fund the coordination process with UTC, which was agreed upon by estimate prior to the publication of the Report and Order in March.  Once the approval is formally granted, the details for the UTC notification procedures will likely be released.  There is also another comment period somewhere in the mix.   A formal “start date” may not be known for a while.  The timing and order of all of these remaining items is very fluid.  Please continue to be patient.  We are making progress.

This was an annoying night for operating and listening in the East and Central portions of the continent because of more active storms that kept a number of stations off air.  What made the night annoying for me was a botched forecast that led me to remain QRT overnight because  of inflated local storm chances.  I’m not a fan of storms so I guess I should be happy that the local weather didn’t make it, which were quite severe out West.  Many stations were QRT and did experience heavy weather overnight.

Geomagnetic conditions reached unsettled levels as a coronal hole moved into a Geo-effective position.  The Bz has turned around to the South this morning and a few periods of elevated protons were observed through the session but those conditions have since returned to normal.  Solar wind velocities are currently at moderate levels, averaging near 470 km/s.  DST values experienced textbook behavior, increasing before decreasing significantly.  Dr. Tamitha Skov has implied that flat conditions are possible over the next seven to ten days, right on cue for field day.




Rick, W7RNB / WI2XJQ, indicates that it was a dismal night in Washington state.  He decoded six WSPR stations and he received reports from sixteen unique stations.

Larry, W7IUV / WH2XGP, provided reports for six WSPR stations and he received reports from seventeen unique stations.  As W7IUV, Larry provided reports for six WSPR stations.

Neil, W0YSE/7 / WG2XSV, provided the following comments and statistics as his antenna comparison experiment continues:

“My antenna comparisons continued last night as I was RX-only again. I am getting conflicting results with some apparent interaction between the two antennas. This is due to the fact that they are too close to each other. I was surprised to see that the loop picked up one decode from Merv/XCR in HI, but the vertical did not hear him at all. It could be that the tuned loop pulled RF from the de-tuned vertical.

Another observation of last night’s results is that the loop was better at distances over about 1000 km, while the vertical was better at distances under 1000 km.

Tonight I think I will compare the Eprobe (PA0RDT mini-whip) with the 5 turn loop since they are about 40 feet apart and should have much less interaction.”

Roger, VE7VV, reported on the ON4KST chat that “last nite was as good as it gets (so far) for me, decodes at max DX to NE, SW, S. No one there to hear me very far to E.”  Roger added in an email that Larry, W7IUV / WH2XGP, is the easternmost station to have decoded him at 299 km and the next stop where stations reside is W9 and W8.  There is room to fill in holes in receive and transmitting stations in the North central US.

Hideo, JH3XCU, provided this link detailing VK -> total JA DX and VK -> JA peak S/N for the session.

Roger, VK4YB, reported that “Reception on my NE beam is impaired by extra noise. An 11kV transformer, about 300m away to the North East has a faulty insulator.  The power company are scheduled to repair it on 4th July. The power will be off for 9 hours when that happens but it will be during the day.  I will have to wait before my reception from North America is back to normal. Other directions are not affected.”  Roger received reports from JA1NQI/2 and JA3TVF.  He shared two-way reports with WH2XCR and he provided reports for WH2XXP.

Roger also noted the end of the seasonal experiment with Dan, VE6XH, where simultaneous measurements have been made for both bands.  It goes to show that both bands are different.  Roger, provided the following comments and chart detailing the most recent reporting period:

“My experiments with VE6XH have come to a close for the time being….[The chart] covers the period 25 Feb to 31 May 2017.  It includes the period of the March Equinox. A few days are missing because of power cuts, antenna damage etc.  There is a nasty dip in conditions, just when things should have been peaking.  As expected 160m fared better than 630m over the 12952 km circuit.  However it is remarkable how well 630m performed. There are 7 days when630m had better S/N, including one when no reports on 160m were achieved.”

Ward, K7PO / WH2XXP, received reports from 24 unique stations including VK4YB.

I started and ended the session with CW due to approaching storms from the West.  It was relatively noisy in the evening  but stronger stations would have been copyable.  Given the distribution of stations that were near storms and in full darkness in the East, it’s questionable as to whether my signal could be copied, however.  Because I knew I was going to be shutting down overnight, I called CQ until 0300z.  No additional QSO’s were completed but I do hope to continue on a similar schedule through the Summer, transitioning to WSPR overnight as weather conditions allow.  Its all about consistency and being in a routine.  I secured the station for the night at 0300z.

Eden, ZF1EJ, was QRT for storms on and around Cayman.

Laurence, KL7L / WE2XPQ, continues to be QRT while on assignment.

Merv, K9FD/KH6 / WH2XCR, provided reports for VK3HP, VK5FQ, and he shared two-way reports with VK4YB.  He received reports from VK2XGJ.  Merv’s DX report details can be viewed here.
