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

Strong geomagnetic storm tempers propagation leaving no question that many magical enhancements are over for a while; VE7AB CW Skimmer online for 630-meters; CW skimmer activity in Europe

The details for September 28, 2016 can be viewed here.

The UTC amateur registration database is hereEven if you don’t think you will use these bands, REGISTER!  Doing so prevents UTC from future PLC coordination in these bands near your QTH.  While amateur interference to PLC systems is a myth and PLC systems are migrating away from RF, there is no reason to give them a reason to do something weird in the future.

The distribution of lightning activity across North America  compared to previous sessions has decreased but the Northeast and parts of the Desert Southwest into Mexico continue to experience active conditions during this session.  North Texas is also very active with periodic evening lightning and continued rain static this morning.  Parts of the Caribbean, particularly off of the Yucatan peninsula,  continue to experience active weather this morning.  Lightning in South Florida has generally subsided this morning compared to the previous session.

Geomagnetic conditions reached G3 storm levels  as the the Kp achieved a value of 7 on two consecutive reporting periods.  Visual aurora is reported down to mid latitudes according to Solarham. The Bz is pointing to the South this morning but off of its most active values and solar wind velocities peaked over 700 km/s during the session with current averages near 685 km/s.   DST values took a nose-dive and are approaching lows experienced earlier in the month during an X-flare event.




Roger, VE7VV, reported that Peter, VE7AB, located in Victoria, British Columbia, has added the modified pattern matching file to his CW Skimmer and reverse beacon system allowing experimental call signs to be accepted quickly when received.  Roger added that Peter’s skimmer is now actively listening for CW on 630-meters.  Thanks to both for their efforts in this regard.  There are also active CW skimmer receivers in Alberta.

I am pleased to reports that there has been some skimmer activity in Europe during this session.  Hopefully this will continue to spread to many CW Skimmer users:


Steve, VE7SL, published this very good 630-meters announcement and FAQ on his website, which is syndicated on amateurradio.com

Doug, K4LY  / WH2XZO, reported that he was “…copied by 10 unique stations including 539 on CW by WG2XJM during our CW contact. Eric was 559.. WH2XZO reported by 33 unique stations on WSPR.”

David, N1DAY / WI2XUF, reported that “Last night was a good night here at WI2XUF.  The first few hours were a little slow with what looked like a local noise interference at the bottom end of the WSPR area of 630M.  Moved my TX frequency up and that helped quite a bit.  I ended up the 12 hour period with a total of 42 unique spots – 10 received by me, and 32 stations reporting my signal.”

Al, K2BLA / WI2XBV, provided reports for nine WSPR stations including three reports of WH2XCR.  Al indicates moderate noise in Florida this morning.

Mike, WA3TTS, reported that he decoded ten WSPR stations overnight, including ” XUF, XKA, WI2XSV, ZF1EJ, XHY, CIQ, XGP, XXP, XSH/15, best DX XGP @ 0652 -24…”  Mike added that he experienced an upload problem due to an invalid grid somewhere in the dataset so he posted the text in dropbox which can be viewed here.

Dave, N4DB, reported that he decoded nine WSPR stations overnight.

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

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, reported that “QRN remains low, but no improvement in propagation tonight, which remains focused on the PNW. Heard 9, heard by 32.”  He received reports from CF7MM, JA3TVF, KJ6MKI, KR6LA, N6GN, N6SKM, VE7BDQ, VE7CA and W7IUV/W. He shared two-way reports with WH2XCR and WH2XGP.

Jim, ZL2AFP, received reports from W7IUV/W and WH2XCR.

Ward, K7PO / WH2XXP, received reports from 56 unique stations including VK4YB, VK2XGJ and ZL2BCG.

Larry, W7IUV / WH2XGP, provided reports for eleven WSPR stations and he received reports from 37 unique stations including ZL2BCG, ZL1EE and VK2XGJ.  He shared two-way reports with VK4YB. As W7IUV/W and using the western seasonal receive antenna, Larry provided reports for ten WSPR stations including VK4YB and ZL2AFP.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity


European 24-hour WSPR activity


Japanese 24-hour WSPR activity


Oceania 24-hour WSPR activity


Eden, ZF1EJ, provided reports for four WSPR stations. He received reports from 24 unique stations.  He shared two-way reports with WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, indicates that the K index in Alaska is currently 8 with visual aurora covering the sky. He notes that propagation is completely cut off and it occurred very quickly.  Laurence only shared two-way reports with WH2XCR and experienced a single “bogus” spot as well.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, provided reports for ten WSPR stations including VK3HP and ZL2AFP. He shared two-way reports with VK4YB, ZF1EJ and WE2XPQ.  Merv received reports from 27 unique stations including 7L1RLL4, JH3XCU, JA1PKG, VK2XGJ, VK7TW, ZL1EE, ZL4EI and ZL2BCG.  DX report details can be viewed here.
