– Posted in: 630 Meter Daily Reports, 630 Meters

Let me begin by saying thank you to all of the individuals that have been sending screen shots, comments, anecdotes and data for use in these daily reports.  It makes my  job a lot easier!

Starting with the daytime session, reports were less frequent compared to previous sessions.  The path to the southeast and WH2XZO did not manifest until much later in the afternoon, closer to sunset.

WG2XIQ daytime WSPR reports

While the Kp index indicated a quiet, stable geomagnetic field, it seems that there might have been enough solar wind ingress to increase daytime D-layer absorption, making daytime reports more intermittent.  While it’s comical to think about nitpicking a Kp of 1 compared to a Kp of 0, there appears to be a difference and one that is not driven solely by reduced solar illumination this time of year.

Neil, W0YSE/7 / WG2XSV, operated his CW beacon during daylight hours and Larry, W7IUV / WH2XGP, commented that the signal was weaker than normal during the day although was audible after dark.  While on the subject of CW beacons, Toby, VE7CNF, reported that Neil’s beacon was audible last evening at RST 429 – 449 at 0145z with no S-meter movement.  Toby also indicated that his beacon was QRV on 476 kHz at 200-watts.  According to his website, Toby is using an inverted-L.  He commented that while he is regularly heard in the west and has been heard in KH6, he has never made it to Alaska or east of Arizona.

In the ON4KST chat/logger, Larry indicated that while conditions were good in the lower-48, the northern path across the continent  was weaker than the previous two sessions, which was evidenced by reports of WG2XJM in PA that did not occur until 10-minutes before sunset in Washington state.  In previous sessions that path was open for at least an hour prior to sunset.  Larry also reports that that path to N6SKM some 1080km to the south in California has been open during the day.

Around 0230z there was a frenzy of JT9 activity between WH2XGP, WG2XSV, WH2XZO, WG2XJM, and WG2XIQ.  QSO’s were made smoothly and with what seemed like few repeated cycles.

WG2XJM – WG2XIQ JT9 QSO details

WH2XZO’s JT9 QSO with WH2XGP was the furthest to date for both at 3385 km.

It was very gratifying to make these QSO’s so easily.  Also quite gratifying was the number of reports that bystanders and receiving stations were providing for these QSO’s.

Eden, ZF1EJ reported that during the QSO with WH2XZO, Doug was -19 db S/N while I was -17 db S/N in ZF1.

Eden also sent a screen shot of his console during the receptions.

In the ON4KST chat/logger, Toby, VE7CNF reported on the XIQ/XGP QSO:

“04:16:20       VE7CNF Toby     Left WSJT-X monitoring earlier. WH2XGP was +8 dB at 0253Z, and WG2XIQ was -22 dB calling CQ at 0258Z.”

Ken, SWL-EN61, sent the following transcript of QSO details that he received during the session:

Rudy, N6LF / WD2XSH/20, reported the following in the 600mrg email reflector:

“Boy, 630m looks hot tonight. I’m already decoding XKA (-23 dB) and five others while monitoring the JT9 QSO between WH2XZO and WG2XIQ!”

If only he had been there the night before!  The path between Rudy and Doug is 3605 km.  That’s quite a haul!  It was a good night to be a radio operator on 630-meters.

WSPR participation was once again very high and that fact paid off as there was a significant amount of trans-Atlantic activity, both to and from Europe.

In the Caribbean, Eden and Roger, ZF1EJ and ZF1RC, respectively, continue to hear very well and make consistent reports.  It is my understanding that Roger is currently using a 160-meter dipole but has ordered a loop like the one used by Eden.  Eden has also expressed an interest in setting up his station for transmitting on 630-meters which is currently permitted in ZF1.

ZF1EJ 24-hour WSPR activity

Ken, K5DNL / WG2XXM, reported 115 spots  at ZF1EJ with a +1 db S/N peak through the session.  He also had 111 spots from ZF1RC.

In Alaska Laurence, KL7L / WE2XPQ, reports generally poor conditions and latent effects of previous, recent solar events but he was heard by a number of stations on the west coast and KH6 and was able to hear WH2XGP.

In the Pacific, Merv, K9FD/KH6 / WH2XCR, reported many of the usual stations, including WE2XPQ and VK3ELV.  Merv also reported WG2XJM and it is my feeling that since reports from that far east are becoming commonplace, I would expect Doug, K4LY / WH2XZO, to be reported in KH6 any time now.

Additional WSPR reports include WH2XGP with 39 unique reporting stations through a single session  and once again a new personal record.  Larry also reports nine experimental stations heard at his station through the session.

Neil, W0YSE/7  / WG2XSV, reported 18 reporting stations which was a season best for him so far.  Neil also got up early to listen for my CQ on 474.5 kHz CW this morning starting at 1010z (3:10am on the west coast!).  He did not hear my signal this morning and the session did not yield any additional QSO’s aside from my daily CW sked at 1030z.  At 1115z I returned to WSPR for the duration of the day.  Thanks to Neil for taking the time to wake up and listen for me.  It is much appreciated.

John, VE7BDQ, reports that he was spotted 4 times by ZF1EJ in the early evening and 33 times by WH2XCR overnight and was QRT at 0940z.
