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

DX conditions took a step backwards as unsettled conditions return and DST takes a dive; Domestic openings were pretty good

– Posted in: 630 Meter Daily Reports, 630 Meters

Long haul reports were down during this session although noise conditions were relatively quiet across North America. The only lightning activity to speak of was over the Atlantic and the buzz heard at my station here in Texas in the previous session was not present.

Geomagnetic conditions are depressed as unsettled conditions have returned and any gains represented by DST have been lost.  Solarham reports that a geoeffective coronal hole is “spewing” solar wind and aurora may be expected for the next 24-48 hours at higher latitudes, with depressed conditions at mid and low latitudes.  The Bz is currently pointing to the North and solar wind is approaching 600km/s with an average over of 590 km/s.  DST values experienced a significant decrease but may be showing signs of turning around.




VO1NA received reports of his CW signal on 477.7 kHz again from PA0RDT who notes that the signal is weaker than earlier in the week as the “sun plays havoc once more.”

Trans-Atlantic WSPR reports were down significantly with WD2XSH/17 receiving reports from LA2XPA and PA0O and WG2XPJ receiving reports from PA0O.  Report details for this session’s trans-Atlantic activity can be viewed here.

Doug, K4LY / WH2XZO, reported that the elevated A and K values and the associated attenuation resulted in a decrease at his station from eighteen WSPR stations heard and fifty stations reporting his signal  to what Doug calls “a modest 13 and 43 with no path to Hawaii.”  Its likely that Doug was reported at WH2XCR but Merv’s Internet was down so those reports do not exist.

Ken, K5DNL / WG2XXM, reported that he decoded sixteen WSPR stations and was decoded by 61 unique stations including KL7L.

Rick, W7RNB / WI2XJQ, reported “Conditions were somewhat diminished from the previous session, noting the lack of  Eastern sea board presence at this location. The spotlight was pointing at the South Eastern US.”  Rick decoded eleven WSPR stations and was decoded by 26 unique stations.  His unique report details for this session can be viewed here.

Ernie, KC4SIT / WI2XQU, reported that he decoded sixteen WSPR stations using the full-size 160-meter inverted-L.  Ernie provided the following additional comments and statistics:

“It was clear and much cooler (30 F) in Flat Rock NC last session. There was an increase of S1-S2 in the noise level over the previous session. Signal strength appeared to be diminished over the previous session when comparing waterfall screenshots of the last two sessions (comparing Wednesday night to Thursday night). However, when comparing Wednesday night to Thursday night in the WSPR database (looking at uniques), Thursday night had better SNR numbers than Wednesday night. I did not expect that.”

Roger, VK4YB, “Summer static continues as expected. TP propagation was a little better with KL7L, VE6XH and W7IUV providing the spots. Only WH2XCR made it through the QRN but WH2XXP was a visual.”

Ward, K7PO / WH2XXP, received reports from 63 unique stations including JA1NQI.

I started WSPR at 2256z but was occupied during the evening so aside from listening to the noise level or assessing my WSPR results today I do not have first hand knowledge of the band performance overnight.  My feeling is, at least at my station, domestic band conditions were very good, particularly in the evening through 0900z.  Tonight Neil, W0YSE/7 / WG2XSV, and I  hope to try an experiment with 1-wpm visual CW.  Its sorta QRSS but not as slow as normally used.  Hopefully the band conditions will permit us to complete a QSO.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

It was another night of high activity with 112 MF WSPR stations observed at 0116z on the WSPRnet activity page.

Eden, ZF1EJ, experienced primarily northern openings as band conditions deteriorated.  He decoded fifteen WSPR stations and was decoded by 29 unique stations.

Laurence, KL7L / WE2XPQ, operated two-receivers overnight.  While high latitude conditions  deteriorated rapidly, Laurence managed reports from the Pacific Northwest, British Columbia and northern California.  His “receive only” position, designated as KL7L, provided reports for VK4YB and WH2XCR. Laurence’s DX report details for KL7L can be viewed here.

Merv, K9FD/KH6 / WH2XCR, reported an Internet outage at his station overnight so his only reports were those of his signal.  He indicates that this weekend a frontal system will pass which historically results in improvements in conditions on 160-meters.  It will be interesting to see if this same system results in an enhancement  at 630-meters.  Merv was reported by 7L1RLL, JA1NQI, and JH3XCU in Asia and VK4YB and VK2XGJ in Australia.  He was heard as far East as my stations here in Texas.  Merv’s DX report details can be viewed here.
