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

Current Operating Frequency and Mode

OFF AIR but QRV after dark tonigth

SCHEDULED ACTIVITY: CQ 474.5 kHz CW by 1015z through sunrise most days, WX permitting

Some trans-Atlantic, FR5ZX hears more EU, numbers increase again, FR5ZX testing transmit setup, VP9GE hearing NA stations and uploading reports, more users on MF WSPR than any other band!

I got a late start last night due to a storm system that was passing through the area.  Fortunately it was only 30 minutes of rain here so I can’t afford to complain too much.

Here in Texas, propagation got off to a smashing start with  single digit and positive reports with many stations in the east from about 0300z to about 0400z.  Losses were much higher here than normal due to the heavy, wet foliage on trees and shrubs that has not yet changed so I can only imagine what it might have been like had conditions been dry.

Larry, W7IUV / WH2XGP, reported this morning that the northern path did not manifest and judging from the limited reports for Laurence, KL7L / WE2XPQ, it seems that the higher latitudes are still being negatively impacted and may not recover before the next round arrives tomorrow with a forecast CME arrival.

The geomagnetic field settled down a bit as the Kp-index generally dropping below storm levels, at least through the overnight period in North America.

The DST remained fairly stable and slightly negative through the session.

Band activity was extremely high.  At 0404z, the WSPRnet activity page, which has historically registered low, indicated 83 stations on 630-meters, which was more stations than any other band where WSPR was being operated.  I’ve never seen that happen before although perhaps it has.  One thing is for sure, 630-meters is becoming a very popular band.

 Daytime propagation seemed active yesterday as WG2XXM ran for a few hours after sunrise.  Reports as far as WH2XRR in Maryland were submitted.  Ken QRTed mid-morning and I was QRT waiting on storms to arrive so its unclear what the afternoon yielded for this part of the country.

Worldwide WSPR activity over the 24-hour period was as follows:

Trans-Atlantic activity was limited to Nova Scotia and coastal Massachusetts and the usual suspects were at play:

In the Atlantic, we have a new receiving station that had very good success for his first session on 630-meters.  VP9GE reported seven North American stations over the approximately one hour time frame that he was QRV.  It is believed that he is used his 160-meter antenna.  Very well done, Ed, and thanks for the reports.  We hope you will report often and for extended periods during the overnight so stations further to the west can have a chance to be reported by you.  Its also my belief that Ed will be able to report Europeans pretty easily on the right night.

In the Caribbean, Eden, ZF1EJ, and Roger,  ZF1RC, hear very well through the session.  Eden reports that this was his best receive night so far, reporting many stations with positive S/N numbers.  Roger also reported Larry, W7IUV / WH2XGP, in Washington state for the first time.

At the high latitudes of Alaska, it was a tough start for Laurence, KL7L / WE2XPQ, but as the evening progressed, he began to see reports to and from the Pacific Northwest as well as Hawaii.

In the Indian Ocean (who would have thought we would be talking about the Indian ocean and  630-meters in the same breath!), the path between Europe and Reunion Island has returned with nine stations being reported to date.

FR5ZX 110615

FR5ZX 24-hour WSPR activity

Also of note is the appearance of Michel, FR5ZX, who is gearing up to be QRV on 630-meters based on reports from FR5DN, also on Reunion Island.

In the Pacific, Merv, K9FD/KH6 / WH2XCR had a banner night, with 524 reports of his signal from 16 unique stations and hearing 10 stations, including Phil, VK3ELV, in Australia.

Merv reports that he has worked out his impedance matching on his antenna system with the help of Eric, NO3M / WG2XJM, and is currently working on getting two 12-volt, 54-amp server power supplies wired in series in order to have 24-volts to drive his amplifier to full power at 100-watts.  Note that prior to this session Merv has only been running 10-20 watts into a marginally matched load.  This might explain why he was heard so well in the east by a couple of stations for the first time during this session including WA9CGZ and KB4OER.  Well done, Merv!

I can also note that WG2XIQ was reported at WH2XCR around his sunset once again, which has been rare so far this season, only being reported so early once or twice before.

In Oklahoma, Ken, K5DNL / WG2XXM, was reported by 46 unique stations, he copied 11 unique stations, had 8 reports from VP9GE, best at -17 db S/N, a best +8 db S/N to ZF1EJ, and a 0 db S/N best to WH2XCR.  Thanks for the statistics, Ken.

This morning during my 1100z CW session on 474.5 kHz, Al, K2BLA, reported that he had a tremendous amount of noise on his receive loop.  He indicated that he thought he could see me CQing in the waterfall but switching to the vertical transmit yielded nearly an S9 signal.  Al was going to investigate further but it just goes to show that on any given day, the  antenna you expect to hear the best doesn’t.  This is a good reason to have many receive antennas on deck and ready to go.  Al will be joining us on 630-meters shortly as he will be assigned a WD2XSH/XX call sign with the ARRL’s 600-meter research group.

My morning CW sked was normal and at 1200z I returned to WSPR2 for the daytime session.
