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

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Another average night with high noise in North America; Less prolific trans-Pacific openings continue but VK4YB, WH2XCR -> JA again; W5EST presents ”Next Monday, August 21 Solar Eclipse! Will You Be There?”

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.

It was “all-noise-all-the-time” during this session, particularly here in Texas, which culminated with a “fire drill” this morning at my station as lightning flashes meant a rude awakening for me and probably others in the region.  The Southwest experienced typical evening monsoon storms impacting activity there and parts of the Southeast also experienced lightning-baring storms that were part of a system that has recently pushed off the Atlantic coast into open water.  Canada was also not immune to lightning activity in both the West and Central portions of the country.

Geomagnetic conditions continue at quiet to elevated-quiet levels.  The Bz is pointing slightly to the South this morning, however. Solar wind velocities have decreased this morning, averaging near 460 km/s off of highs that peaked above 600 km/s for brief periods.   DST values are at or near the centerline.

David, N1DAY / WI2XUF reported:

“As with previous nights, I have observed that my distant TX/RX contacts are occurring from about midnight into the early morning hours.  It appears that a lot of the listening stations may be QRT before the band really starts to cook.  25 unique spots here last night. Seven were received at my QTH and 18 reported my signal.

It has been a real challenge keeping my transmission line and antenna matched at somewhere close to 50 ohms impedance due to the unusual weather pattern of rain for this time of year in the NC mountains.  To work around this, I took a couple of windings off my main inductor coil and built a transmatch unit using a mix 77 toroid with multiple taps and a much smaller coil to cancel out the small amount of capacitance induced by removing turns on the main inductor.  The picture is attached.  It is working like a charm and I can now manage the changes in impedance that mother nature is throwing at me.”

Al, K2BLA / WI2XBV, reported high noise in Florida.  He provided reports for five WSPR stations.

Mike, WA3TTS, reported that he decoded seven WSPR stations overnight, including his session best DX, WH2XGP at -15 dB S/N in addition to WH2XXP, ZF1EJ, WG2XIQ, WI2XSV, WI2XUF, and WH2XXC.

Dave, N4DB, indicated low QRN in Virginia where he reported decodes for seven WSPR stations including “…WH2XGP at 3489km and WH2XXP at 3109km…”

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, reported “Less activity down-under, some QRN. Moderate TP propagation but spread widely including to JA. The NE beam is in use. JA beam is not repaired yet.”  Roger received reports from VE6JY, VE6XH, JA3TVF, JA1NQI/2, JH1INM, W7IUV and WH2XGP. He shared two-way reports with WH2XCR.

Ward, K7PO / WH2XXP, received reports from 47 unique stations including VK7TW, VK4YB, VK2XGJ, VK2EIK, VK3ALZ, and VK5AKK.

It was another late start for me but I was QRV by 0300z when it was just about dark.  The days are getting shorter but its not enough for my liking yet.  Noise level was very high before dark and adjusting antenna direction only moderately helped the situation.  Reports began like normal from the Midwest and Southeast but my activity during the session was largely an exercise in comparing band performance with other recent sessions to evaluate seasonal progress.  It’s clear we are in the middle of August but I would say that the band is improving some.  Nothing really surprising was observed except for the abrupt wakeup to flashes through the window at 0930z, meaning it was time to get disconnected, and fast.  This morning reminded me why my activity has been sparse this Summer and why it probably should continue to be sparse until the weather calms down for persistent periods or band conditions improve significantly.  My transmission report details can be viewed here and my reception report details can be viewed here.

“In just one week comes this decade’s major solar eclipse event for North America!

For 630m people, the sun and moon will scan the D-region and E-region from the North Pacific through Oregon to Nebraska to South Carolina to central Atlantic Ocean off West Africa. 630m transmitters and receivers should run all day if possible so you have baselines for comparison of pre-eclipse, eclipse run, and post-eclipse.

Even if clouds where you live keep you from visually viewing the eclipse, your radio will “see” through the clouds to the eclipse-darkened ionosphere above.  WSPR2 is relatively static-resistant, so even noisy 630m conditions can allow you to acquire useful decodes and SNR sequences.

Take best advantage of the solar eclipse Monday, August 21.  The solar eclipse will cross XCR-XPQ signal path 1600-1700z after Alaska and Hawaii sunrises next Monday morning.

Canadian and continental US stations will then get about 3 hours of on-stage eclipse action—1630z-1915z — 9:30am PDT to 3:15pm EDT.

In the central US where I live, 1:00-1:30pm CDT local time may likely present the 630m peak of the eclipse magic for this area.

This remarkably favorable eclipse track extends diagonally right across the continental USA.  The small oval of eclipse totality will be on the move somewhere in this country for 1 hour 33 minutes, 1715-1848z next Monday, August 21.   But the radio action can also precede and follow the geographic position timings too.

Savvy station operators already know every station’s participation matters —receiving or transmitting on 630m.  Because of the rapidly unfolding eclipse dynamics, 630m WSPR2 TX stations should transmit a relatively high TxPct, such as 50%. That way, each RX station can probe the propagation dynamics impressed by this historic solar eclipse on “our” 630m  ionosphere.  (Some 630m TX stations may want to use somewhat lower percentages if they have advanced receiving antennas and equipment for themselves to monitor more WSPR2 slot intervals.)

During the month of May, your KB5NJD blog ran several articles to advance your preparations for this eclipse. For more background on the August 21 solar eclipse, I invite you to reread these blog posts:



TU & GL with the 630m eclipse next Monday Aug. 21!”
