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!

Another historic session as W7IUV completes a two-way JT9 QSO with VK4YB at a distance of 12002 km; Slow start for openings in the evening in spite of relatively quiet band conditions but session finishes strong this morning; ZF1EJ -> G8HUH, AA1A -> EA8BFK on WSPR

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for October 17, 2016 can be viewed here.

The UTC amateur registration database is here.

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

Curious about who is on the air making two-way QSO’s?  Roger, VE7VV, is maintaining this list.  If you complete QSO’s, be sure to let us know so he can add you to the active operator list.


It was a much quieter session for many than has been recently experienced as the lightning map was generally clear in the continental US.  The Southeast experienced the bulk of lightning activity with storms continuing this morning in Florida from the Gulf of Mexico to the Atlantic.  Roger, VE7VV indicated lightning QRN last night where he could not determine the source. Its possible it was propagated from very far away.

Geomagnetic conditions were marginally better, remaining at quiet levels.  The Bz is pointing slightly to the South this morning and solar wind velocities are averaging near 460 km/s, down from an average of 520 km/s through the evening.  DST values remain at negative levels but there have been fewer deep decreases observed than in the previous session.




The band was slow to open during the evening in spite of quieter geomagnetic and terrestrial weather conditions.  Signals did not come into their own until about an hour after dark here in North Texas.  Larry, W7IUV, reported that East / West propagation was very poor during the evening.

Jim, W5EST, submitted these JT9 reports receive at his station in Little Rock, Arkansas during the evening:


Many stations took the time to report their completed two-way QSO’s to me for the session and those reports, in addition to other  session details, follow:

The big news for the session was that Larry, W7IUV, located in Washington state, completed a JT9 QSO with Roger, VK4YB.  As far as I know this is the longest two-way JT9 QSO under amateur radio rules on 630-meters, beating the distance of the QSO between VK4YB and VE7SL on September 15, 2016 by about 200 km.

Larry also completed a long transcontinental JT9 QSO with Al, K2BLA, located in Florida.  Eric, NO3M, indicates that he was also seeing JT9 reports from Larry this morning but missed him.  Larry also reported K4LY but Doug QRTed before a QSO could occur.  Larry noted that evening conditions were very poor so he did not hang around long and indicated that most of his time will be spent on JT9 as his operating style is incompatible with the operating style of many CW operators on the band.  He provided these statistics for the session:

“I managed to work on CW:


And on JT9:


This morning it was better. On JT9:


Totals for the last two days:

21 QSO’s
16 initials
7 states
1 province

I have copied ZF1EJ and he has copied me, we just need to put it together. Have also copied, at various times, several Midwest and east coast guys on JT9. So there is some hope.”

In addition to his two-way JT9 QSO with Larry, Roger, VK4YB,  received WSPR reports from JA1PKG, JA1PKG/2, JA3TVF, JE1JDL, JR1IZM, K3RWR, KPH, KR6LA, N6GN, N6SKM, VE6JY, VE6XH, W6SFH and WA7LNW.  Roger shared two-way WSPR reports with W7IUV/w, K9FD and K5DNL.

Eric, NO3M, reported a CW QSO with Fred, N3FL, located in Maryland.  Fred reported that “NO3M was 569 at peak but was perfectly copy for the virtually the entire QSO. He was my first CW contact on the band. Also worked K4LY but just barely. He gave me a 449 at my best but we struggled to get my call correct. I also heard K4EJQ but he was unable to hear me. I was running less than 800 mW.”

Fred’s system consists of base loading via a variometer “…and the flagpole. It is 30 feet tall, has 32 buried radials 33 feet long. The base is about 80 feet from the water. The flying saucer on top of the flagpole is a solar light to illuminate the flag when it is being flown.”

Doug, K4LY, located in South Carolina,  completed four QSO’s, adding that:

“QRN moderated, and conditions to the west, especially Hawaii, improved, but high latitude absorption still with us.  The highlights were working four new stations and states on 630M-

WA3ETD, VT, on JT9    -24 sent  -25 rcvd
WA9CGZ, IL, on JT9;     -25    -25
N3FL, MD, on CW;         449    589
K4EJQ, TN, on CW.        569   449

Am spending less time on WSPR now and with only 40-50W TPO until I figure out why transverter shuts down with higher power.  On CW and JT9, I run the normal 65 watts TPO which I think is close to 5W EIRP..  On WSPR was spotted by 48 unique stations including K9FD/KH6 nine times.  Spotted him 7 times plus 12 other stations.

I got up briefly to see if anyone was operating JT9 at 1000 UTC.  It was quiet except for John on CW.  Wonder when the best time might be to try and work west coast stations?  Might we schedule activity hours a few times a week to help concentrate activity?”

Here is a recording of Doug as received at my station on CW through one of his calling episodes before the band really opened up:


John, WA3ETD, reported that he operated JT9, completing three QSO’s in addition to a long WSPR report from the evening.   He offered these comments and statistics:

“WA3ETD ran JT9 from 2300-0000, completing the exchanges with K4LY, N03M and K2BLA.  I then transitioned to WSPR and was spotted early by N5CEY at -26 in S. Texas – good ears!  Really early.

01:16  WA3ETD  0.475720  -26  0  FN33lq  2  N5CEY  EL16gc  2943  236

Overall, heard 10 and was spotted by 44.  WX here was clear and cold, but noise levels remain above average.

I plan on running FT-8 going forward, as the latest pre-release version Version 1.8.0-rc3 exhibited none of the installation funnies previously encountered!”

Neil, W0YSE/7, submitted this report of his session activity:

“It was fun to watch Larry and Roger complete a JT9 QSO this morning. I never saw Roger’s tracks, just Larry’s.    Ken, K5DNL and I completed a JT9 for the first time ever, I believe. I dont think we even did it with our part 5 calls.

This session I had JT9 QSO’s with Ken/K5DNL, Larry/W7IUV, Rick/W7RNB, and almost with Dick/W7WKR.   Dick said that I had 3 images and he clicked on the wrong one which may have contributed to the lack of completion. I obviously have power supply issues again because Larry also is seeing multiple images of my signal.

I had CW QSO’s with AH6EZ/W7 who is NNW of Seattle on the Olympic peninsula, and Rick/W7RNB in Edmonds, WA which is north of Seattle.  I also heard CW stations N6LF and K7SF in QSO last evening.”

Toby, VE7CNF, reported JT9 QSO’s with W7IUV, W0YSE, VE7BDQ and “new stations for me NU6O, N6GN, N1VF, K9FD.  Also had another nice CW QSO with AH6EZ/W7.”

Roger, VE7VV, reported JT9 QSO’s with  “three new stations: N1VF (best DX so far 1192 km), W7WKR, N6GN.”  Roger added that that there was a large amount of lightning QRN present later in the evening but that activity was not being reported by Blitzortung so Roger does not know what the source might have been located.

Ken, K5DNL, reported that he completed two-way JT9 QSO’s with WA9CGZ, K9SLQ, W7IUV and W0YSE.  He also noted that he decoded VK4YB once in his pursuit of a QSO with Roger.  Overnight, he provided reports for fifteen WSPR station including VK4YB and he received a reports from 66 unique stations including VK4YB and ZL2AFP.  He shared two-way WSPR reports with K9FD and ZL1EJ.

Joe, WA9CGZ, reported that he completed two-way JT9 QSO’s with K5DNL, NO3M, K9SLQ, K4LY and K2BLA.

Rick, W7RNB, reported a very interesting night of JT9, WSPR, and CW.  During the evening around 0300z, he completed the following QSO’s:

“CW on 475.xx – I worked —
VE7CA  529/559
N6LF    579/569
W0YSE 539/539
Then JT9 —
W0YSE  -16/-10
W7WKR -18/00
Heard but not worked K5NDL -26″

On WSPR, Rick  provided reports for ten WSPR stations and he received reports from 32 unique stations including sunrise reports from ZL2AFP.  Rick’s unique WSPR report details can be viewed here.

Al, K2BLA, completed a two-way JT9 QSO with Larry, W7IUV, and operated WSPR through moderate QRN which he reports was better than the last session.  Al provided reports for eleven WSPR stations including K9FD (KH6) and he received reports from  32 unique stations.

Jan, LA3EQ, reported JT9 QSO’s were completed with DL6TY, DH3FBI, F4GUK, OR7T, ON5TA and  IW4DXW. He added that “Heard was G3KEV.”

The band was very slow to open in North Texas.  I heard Doug, K4LY, around the time that it was fully dark but he was weak,  maybe RST 449.  He reported that my CQ’s during the same period were around RST 339.  It took about an hour after full dark for the band to really develop afterwhich signals from NO3M and K4LY were quite strong on peaks with fast QSB present once again.  I received early reports from Nick, WA5BDU, located in Russellville, AR, who indicated that,

“You are the first signal I’ve ever copied on 630 meters, coming in loud and clear on CW, 474.5 kHz from 0030 to 0047 and counting.  I’m using my FT-991A receiver and a 130′ inverted L which I use for 160 meters.

I’m currently not making any attempt to match the antenna to the coax. And not anywhere near transmitting yet.”

Thanks Nick!  I also received a report from the Larry, W0OGH, from the 600-meter research group email reflector who indicated that he heard my CW sked with Steve, KF5RY, around 0143z.  He noted that he was not hearing Steve.  Steve was only using about 1-watt TPO to an 80-meter inverted-vee fed as a droopy Marconi-T with base loading against station ground.  Steve hopes to add more power and better receive conditions in the future.

I also had a great highlight of working Steve, KK7UV, near Missoula, Montana on 474.5 kHz CW this morning.  Steve noted that I peaked out of the noise briefly to call and send me an RST 449 report.  At the time of the peak Steve was a true RST 539 and best on the short, high impedance vertical compared to the directional arrays.  You can never have too many receive antennas!  Steve and I have struggled to work in the past under experimental rules so it was nice to check that box so quickly under part-97 rules.  W7IUV reported my CW signal in Washington as he was working JT9 and I received reverse beacon network reports from both coasts so the band was in pretty good shape this morning with low noise.  Eden, ZF1EJ, reported me at RST 439 but was not configured for a CW QSO this morning.  Set your alarm and make some coffee – operators are standing by for your calls!

Larry, W0OGH, located in Cochise, Arizona, sent me these comments on stations heard or decoded during the evening:

“Here’s what or should i say who i heard last night, Oct. 17, 2017 Zulu time.
N1DAY    0406Z-0850Z    EM85    4 times
K2BLA    0934Z-1104Z    EL99    5 times
K3RWR    0346Z-1050Z    FM18    8 times
WA3ETD   0738Z-0752Z    FN33    2 times
K4LY     0402Z-1114Z    EM85    16 times
K5DNL    0348Z-1128Z    EM15    56 times
N6GN     0752Z-1318Z    CM88    12 times

W0YSE    0740Z-1132Z    CN85    19 times
VE7BDQ   0120Z-0840Z    CN89    3 times

Heard you on CW with a KF5 on CW before 0400Z but couldn’t hear him.  You were audible without cans on my head.

Copied W7IUV on JT9 2 times abt 0400Z but didn’t write down the times.  He had a good signal here on the screen, vri strong but i thot i’d see more from him, didn’t!

Ant is 80M dipole for around 3620Kc and ony about 35 ft high in middle.  Use a K3 for receive.

Nice seeing a bunch of signals on the band although some i couldn’t decode.  Band was quite quiet here with noise floor around S4, peaks to S9 but lots of quiet times.”

Bill, AC6QV, posted the following comments on the 600-meter research group email reflector:

“There was a rare low noise at my house last night and I listened at 475.37 KHz from 0328 UTC to 0348 UTC.   The following stations were heard:

W7RNB  559 (Rudy just to the north of me gave him a 579)  15 minutes later he was on again with 579

N6LF  579   he must have something directional that shines away from me or he would be pegging the s meter

VE7CA 559

W0YSE 559  (W7RNB gave him 539)

I am thinking there was another but it is not on the paper I am reading from.  The receive station was an old Kenwood R5000 receiver with a voltage probe whip up about 12 feet on a two x four out in the yard.”

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.

Trans-Atlantic WSPR report details can be viewed here.

Dave, AA1A, received seventeen WSPR reports from EA8BFK.

Eden, ZF1EJ, received two WSPR reports from G8HUH.

Mal, G3KEV, indicates that he received reports from many European stations in addition to TA4/G8SCU at a distance of 3049 km and EB8ARZ at a distance of 3149 km.  Mal indicates that these reports are his best to date.

Roger, G3XBM, indicates that he added a few more radials and continues to operate near 10 mW EIRP.  He added that he provided reports for ten WSPR stations and he received reports from ten unique stations although notes that his “regular” reporting stations are not decoding at higher values.  He continues to evaluate and improve his system.

David, N1DAY, reported that he “…had another good night on 630M WSPR with a total of 66 unique spots.  12 RX and 54 TX.  The exciting news is that my signal was spotted in Hawaii which is a first at my station!!!  25 of the stations reporting my signal were at a distance >1000 km.”

Mike, WA3TTS, reported that he decoded fifteen WSPR stations overnight, including, “…10 spots for K9FD, best -20 @ 0826, 3 spots for W0YSE, best -30 @ 1110, 15 spots for ZF1EJ, best -19 at 0902 and 0952.  N8OOU doing something right as I decoded his +13dBm signal 41 times overnight, best -12 at 0510 and a minimum of -25 at 0130 utc.  Also received 90 of 121 possible decodes of WH2XND on 2200m band from 0348 to 1144 utc for 74% capture rate. NW EWE antenna was used overnight to drive an LF/MF hybrid splitter into separate filters and receive converters.  This arrangement seems to work better than a single 500 kHz LPF and converter followed by an IF hybrid splitter.”

John, VK2XGJ, reported that the problems with decoding K9FD’s signal have been resolved and he has provided plentiful reports for Merv this morning:

Eden, ZF1EJ, provided reports for seven WSPR stations and he received reports from 38 unique stations including PJ4VHF, WH2XCR and G8HUH.  Eden spent the morning on JT9 and received W7IUV on three consecutive cycles but Larry never heard him.  Eden also reported my CW this morning at RST 439.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, indicates that he “only had the tx on for a short while early in the night john but appears high lat absorb still there – I did see a very weak Au blue green arc to the NE around 1145 MST…”  He provided reports for three WSPR and he shared two-way reports with K9FD.  DX report details can be viewed here.

KL7L 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, provided reports for seventeen WSPR stations including ZF1EJ. He shared two-way reports with VK4YB, ZL2AFP, ZL1EE and ZL7L. Merv received reports from 48 unique stations including JA1PKG, JA1PKG/2, JA3TVF, JE1JDL, JR1IZM, VK2XGJ, VK3ALZ and VK7TW.   DX report details can be viewed here.  Merv noted that there was quite a bit of QRN last night and the band was experiencing “strange QSB again, signals going from -10 to -25 in one cycle.”  Merv also indicates that he heard W7RNB’s JT9 at -10 dB S/N best report but Rick never heard his calls.
