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

Slightly better activity and improvements on trans-Pacific paths; Noise continues to be a factor; W5EST presents ”630m D-Region Sunrise from RF Path Viewpoint”

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for July 25, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  That includes stations using fake or pirated call signs.  Please continue to be patient and let the FCC finish their processes.  UPDATED: Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.

Storm activity in the western US was widespread during the evening and overnight while a strong storm system in central Canada progressed to the East.  The large storm system that had been plaguing the East coast finally moved off to sea, however and the Caribbean and Southeast continue to experience spotty storms.  Dave, N4DB, located in Virginia, commented that last night was the first in quite a while that he did not experience lightning overnight.

Geomagnetic activity sent mixed messages again as unsettled levels were reached during one reporting period followed by several periods of elevated-quiet conditions.  The Bz is currently pointing to the North but solar wind velocities were in excess of 700 km/s during the evening and are currently averaging near 600 km/s.  DST values continue at variable but negative levels and the A-index is currently at or near 12.

 

 

 

David, N1DAY / WI2XUF, reported some success after a late start at his station.  He explains:

“By 2:00 UTC all of the electrical storm activity due north of me had dissipated and in short order I was spotted by just about every active station in the Great Lakes Area.  No luck to the Northeast though and a quick view of lightning activity showed a massive storm in the DC area that seemed to be blocking everything in that direction.  I recently swapped out my variometer for a single coil inductor and so far it seems to be performing well. The goal here was to reduce stray capacitance to ground by replacing the tightly wound variometer with something a little more loosely wound and maybe squeeze a few more dB out of the antenna.  If anyone has thoughts on the value of dong this, I would like to hear from them.”

Dave, N4DB, reported an electrically quiet night in Virginia.  He provided reports for four WSPR station including ZF1EJ, WH2XXP (best DX at 3109km), WG2XXM, and WI2XUF.

Neil, W0YSE/7 / WG2XSV, reported that he operated in a receive-only capacity using his E-probe.  He provided reports for four WSPR stations including WH2XCR, WG2XXM, WH2XXP, and WH2XGP.

Mike, WA3TTS, reported that he decoded four WSPR station including “…WH2XGP, best -15 0948Z, WH2XXP, best -4 0942Z, WG2XXM, best +4 1002Z, and WI2XUF best -11 0942Z.”

Hideo, JH3XCU, submitted this link detailing DX -> JA spot totals and peak S/N, as reported on the Japanese language 472 kHz website.

Roger, VK4YB, reported at 1142Z that he was QRV JT9 on 475.46 kHz.  He also received WSPR reports from 7L1RLL4, W7IUV, WH2XCR, and WE2XPQ and he provided reports for WH2XXP and WH2XCR. Its good to have Roger active again!  He added that “While I was ill, high winds damaged my antennas. I repaired the JA beam today. I hope to put back the NE beam on the weekend. This will improve my receiving.”

Ken, K5DNL / WG2XXM, reported that he provided reports for two WSPR stations and he received reports from 37 unique stations including ZL2AFP, E51WL, WH2XCR, ZF1EJ, and five Canadian stations.

Larry, W7IUV / WH2XGP, provided reports for three WSPR stations and he received reports from 29 unique stations including ZL2AFP an E51WL.  As W7IUV, Larry provided reports for five WSPR stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from 45 unique stations including ZL2AFP, ZL4EI, VK2KRR, VK4YB, VK2XGJ, and E51WL.

I spent the session exclusively trying to figure out some on going problems with my CW skimmer integration with the Reverse Beacon Network.  I’m doing the testing on HF where I know I can gathers lots of data but this project is ultimately for 630-meters.  Copying stations does not seem to be a problem at all although initially I thought this was the step where the process was hanging up.  Consistently uploading to the RBN seems to be the real problem and I am working a number of angles to attempt to gain some consistency.  What I have observed thus far is that I might be lucky enough to upload a single spot or cluster of spots but after that the process seems to choke and no matter how many decodes are listed in CW Skimmer, none seem to upload.  I’ve wondered if the Telnet connection is failing due to poor quality Internet here.

Since I am not blocking any of the services used to upload data, my first thought was that this was some type of permissions problem with the folder.  I have located the folder in the root and I am running the program as administrator and have also de-selected the option to “protect data in the the folder” (this is an OLD XP install).  Writing to objects in the folder should not be a problem.  I also reinstalled the .NET framework version 4 which is required for Aggregator to work properly.  Looking at the status page in Aggregator, systems are nominal.  I have selected to save telnet logs but in the most recent clean start, there is no data in spite of a number of decoded stations.  I should also note that the current downloadable version of Aggregator on the RBN site is 4.4 but I get a message when I connect to RBN that the current version is 4.3.  Could there be a version conflict on the server and I am being cut off because my version is not recognized as the version?

I’m also starting to think that I may have to yet again upgrade the operating system to make this work.  It’s been a very frustrating process and documentation seems to be spread over a number of sources and out of date in many cases.  I think my next stop with be the Yahoo group.  If you have any recommendations, please let me know.  I’m almost out of ideas to try.

Jim, W5EST, presents,  “630m D-Region Sunrise from RF Path Viewpoint“:

“In yesterday’s July 24 blog, its geometric diagram showed the D-region as if it were “eyeball-shaped.” It took a view along the Earth’s orbit plane and along the terminator plane on-edge.

Today, let’s shift viewpoint and look at a 630m RF path as if it were stationary. For clarity, its path height to an E-region reflection is exaggerated relative to the Earth below.

In the illustration here, see successive Roman numerals iv-xiii enumerating angles of the Sun’s rays in successive time intervals when night-to-day 630m SNR is ramping down.  Isn’t it odd that the rising Sun at ionospheric altitude starts by illuminating the middle of the RF path first? The Sun’s illumination then proceeds to work its way backwards down toward the eastward 630m station and with perhaps some delay also works forward down to the westward 630m station.  TU & GL!”
