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

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

In spite of continued G1 storm conditions impacting some high latitude paths, good night for trans-Pacific reports including first time reports of VK4YB at W0JW; Trans-Atlantic paths favored low latitude paths between North America and EA8; Nice sunrise peak results in two-way CW QSO between WH2XZO and WG2XIQ

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.

HERE are a  few mode specific comments addressing where modes are located now and probably where they are best placed in the future


Most of the North American mainland was storm-free this morning although a few lightning-rich storms were active in the Atlantic, East of Florida and North Carolina.  Southern Mexico remains very active as well but lightning crashes are minimal here from that direction so propagation may be factoring into noise or lack of it.

Geomagnetic conditions continue at unsettled to G1 storm levels as a coronal hole remains geoeffective. The Bz is pointing firmly to the South and solar wind velocities are averaging near 560 km/s. DST values continue to meander at negative levels with a few deep decreases observed.  KL7L referred the high latitude band conditions “dire” around 0800z.




Roelof, PA0RDT, submitted the following comments about his receiving session of VO1NA’s CW signal overnight:

“Good signals early in the night, followed by an extended fading period and then a nice pre-dawn enhancement.  The signal was 8 dB above the (quiet) band noise and aural copy was no problem.”

Reverse beacon network reports for the session follow:


David, G0MRF, extended his best wishes on opening night in the US and reported that he completed an FT8 QSO:

“I finally made my first QSO using FT-8 last night. Very pleased that it was on 630m. I managed to work Ian, G4GIR, over 80km or so after hearing him calling CQ.  The ICOM 7300 worked well. Not the best receiver out there, but running digital modes via the radio’s USB interface takes all the hard work out of interfacing the radio to the PC.

Another reason, perhaps the best reason for today’s mail, is to say best wishes to you and all the other 630m pioneers who finally will have access to the band with your home calls.  I hope you have a day off from work on Monday….It looks to be quite a party.”

EB8ARZ received reports from John, W1TAG/1, currently located in Maine.

Ken, K5DNL / WG2XXM, provided reports for thirteen WSPR station and he received reports from 54 unique stations including EA8FBK (eleven reports, best -24 dB S/N)  and five Canadian stations.  He shared two-way reports with WH2XCR, ZF1EJ and VE3CIQ.

Doug, K4LY / WH2XZO, reported that he decoded twelve WSPR stations and he received reports from 43 unique stations.  He shared two-way reports with WH2XCR and added that the session had “…good activity and pretty good conditions. Highlight was CW Q with WG2XIQ peaking 579 both ways.”

David, N1DAY / WI2XUF, reported that he was “…back transmitting again last night.  I had a total of 32 spots, and 12 spots I reported.  This was my first time receiving Hawaii.  Noise was low here last night and thing were pretty steady throughout the evening.”

Rick, W7RNB / WI2XJQ, provided reports for six WSPR stations and he received reports from 22 unique stations. Rick’s unique report details can be viewed here.

Al, K2BLA / WI2XBV, provided reports for thirteen WSPR stations including WH2XCR and VK4YB and he received reports from 36 unique stations including stations located inVE3, VE6, and VE7.  He also reported my CW at RST 589.

Neil, W0YSE/7 / WG2XSV, reported that he “…hrd only these 6: WG2XSV Hearing: WG2XXM, WH2XCR, WH2XGP, WH2XXP, WI2XJQ, WJ2XBZ as I was RX only due to WX here.”

Mike, WA3TTS, reported “Good T/P to Hawaii overnight with 21 XCR decodes on NW EWE antenna.

A total of 13 630m stations heard overnight, AK7FR is a false decode, interesting that KU4XR had the same false decode at the same time but a different frequency

Also 100 of 160 WH2XND transmit sequence decodes on 2200m, best SNR -16 from 0100 to 1140 utc, 62.5%  decode rate with e-probe, 300 kHz LPF, and modified HD-1420…PS: Diplexer and Filter YouTube Video https://www.youtube.com/watch?v=mrbXRFwrKNM

Dave, N4DB, reported that he decoded twelve WSPR stations.

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, received reports from JA1NQI/2, JA1PKG, JA1PKG/2, JA3TVF, JR1IZM, KA9CFD, KR6LA, N1VF, VA7JX, VE6JY, VE6XH, VE7BDQ, W0JW (first time report), W5TTY, W7IUV, WE2XPQ  and WI2XBV. He shared two-way reports with WH2XCR and WH2XGP.  Roger also added that he “…called CQ on CW for 40 minutes at this time last night trying to get into 6JY’s skimmer. No luck.  My signal is down with Don tonight so i think I will give it a miss.”

Jay, KA9CFD, reported that he decoded twelve WSPR stations including WH2XCR and VK4YB.  Jay added that this was probably his best trans-Pacific session to date.

Ken, SWL/K9 (SWL-EN61), located in Indiana, reported that he received the dreaded “<…>” for whom we believe is VK4YB.

Ward, K7PO / WH2XXP, received reports from 54 unique stations including ZL2AFP and ZL2BCG.

Larry, W7IUV / WH2XGP, provided reports for fifteen WSPR stations and he received reports from fifty unique stations including ZL2AFP, ZL2BCG, and VK2XGJ.  He shared two-way reports with VK4YB.   As W7IUV, Larry provided reports for ten WSPR stations including VK4YB.  Larry indicated that he “Decoded VK4YB right up to my sunrise.  Condx abt same as last couple nites, all the usual suspects in all the usual places.  Was nice to see ZF1EJ return to my “heard” list.  35 decodes from VK4YB on my west RX, best at -20, down from best nites.”

Elecraft included a few notes in their October 2017 newsletter about using their products on 630-meters.  That newsletter can be viewed here.

This session began for me at 2352z, with a few calls on  474.5 kHz CW.  There was a bit of confusion as to where another station was transmitting but once we determined that neither station was co-located operations returned to relative normal.  Dave, N4DB, reported that my signal was just out of the noise after full dark.  No early QSO’s during this session.  I QRT’ed for the night at 0100z.

After listening around a bit, beginning around 0945z, I wasn’t hearing much so I began calling CQ again on 474.5 kHz CW.  Noise levels were relatively quiet to the East and even quieter to the West.  I heard periodic pings but I don’t think they were tied to a real station.  I received Reverse Beacon Network reports from VE6WZ at 1056z, followed by reports at 1110z and AA4VV reported  partial call signs for me near his sunrise at 1104z and at 1120z.  I’m not so sure that fast QSB or noise was impacting my reports at his receiver.   Doug, K4LY / WH2XZO, was QRV around 475.3 kHz calling CQ and popped out of the noise, calling me off freq loud enough that I could hear that he was there with a filter in place.  We exchanged RST 579 QSB reports with each other and went on our way.  His signal peaked up nicely through his sunrise period.  Any morning with a QSO is a good one, I don’t care what propagation or noise is like.

I have a request followed by a rational:  It would be helpful for anyone “setting up shop” on a frequency to post that activity in the ON4KST chat or on the 600-meter research group to avoid collisions.  With the possibility of many signals existing within a few kHz, I suspect collisions will be commonplace  as signals pop out of the noise and disappear again.  The real problem exists when another station can hear both signals simultaneously but due to co-location can’t work either station.  Its easier to just spin the dial and keep moving rather than try to sort that out.
