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

Excellent domestic openings that seem to coincide with more unsettled geomagnetic conditions; A few trans-Atlantic reports return while trans-Pacific reports “dry up” a bit; Good night for CW and quite a bit of digital activity in VE7

The details for April 8, 2016 can be viewed here.

It was a rare, very quiet April night for much of North America resulting in a few European stations being reported in New England, a number of armchair copy CW QSO’s, and several digital mode QSO’s in British Columbia.  Domestic WSPR openings were better than they have been in over a week, possibly longer and there were a number of new stations receiving on 630-meters for the first time.

Geomagnetic conditions reached unsettled levels once again for multiple reporting periods.  The Bz has moved back to the South and solar wind velocities have increased to moderate levels, averaging 570 km/s this morning.  DST values have drifted back to negative values after a few days of improvements.




Eric, NO3M / WG2XJM, reported two CW-QSO’s during the evening, the first with Carl, N4PY / WI2XSX, which may have been Carl’s first QSO.  Openings over the 1200-mile distance to Eric from my station here in Texas began a bit later after about an hour of darkness.  Band conditions were very good as noise was uncharacteristically low and signals were armchair copy, which is atypical for this time of year.  We could have continued for quite some time as following WSPR reports suggested continued improvements in the opening.  While I am hopeful that we will see more late season, quality openings like this, I believe this opening was quite rare based on the last five years that he and I have been QRV on 630-meters.  I hope I am wrong.

Mal, G3KEV, reported CW QSO’s with stations in LA, DJ, and IK2.

Joe, VO1NA, submitted these comments and an operational announcement for his new amplifier  on the RSGB-LF reflector:

“On Tuesday a new tx (gw3uep design) was built and worked very well. An IRFP140, sm capacitors and 1mm wire was used although L2 (7uH) beacme quite warm.  The 1 uF  caps (type unknown… yellow and stamped BEC C11C) did their bypassing without complaint.

Roelof had an O copy on yesterday morning (the 7th) during the first on the air test.

G4JNT Andy’s explanation of how the reactances are absorbed by the L network which brings the drain impedance to 50 ohms is enlightening. Is there a way to find impedance at the drain or is this just the R value on Alan’s G3NYK Class E spreadsheet?

The new TX will be on again 9 Apr. 0000-0900 utc.

Hopefully this design will be merciful on FETs.  If not, there’s a 3-500 waiting on the shelf.”

Roger, VE7VV, reported quite a bit of digital mode activity in British Columbia, including WSQ2 which has not seen a lot of acceptance in North America due to the very slow speed.  Roger explains:

“…qso’s in 0400-0510 period. 474.2 +1000 WSQ mode – VE7BDQ, CF7MM, VE7VV with each other. DominoEX4 mode – VE7BDQ with CF7MM and with VE7VV. Larry W7IUV reported that he copied the DominoEX4 from John and Mark.  The DominoEX4 qso’s were a lot of fun, with character rate about as fast as I can type! Nice to be able to have a real chat type qso on 630 mtrs!”

A few trans-Atlantic openings were observed overnight after several sessions of no serviceable paths.  Report details can be viewed here.



Paul, N1BUG / WI2XTC, reported very low QRN.  He decoded eleven WSPR stations including DH5RAE, G8HUH, and WH2XGP.   Paul also indicated that “WG2XJM very strong signal (of course) on CW.”

Ken, K5DNL / WG2XXM, reported  that he decoded ten WSPR stations and was decoded by 65 unique stations with N1BUG and VE7CNF as his best DX, both at a distance of 2603 km.

Al, K2BLA / WI2XBV, reported “descent conditions for a change”.  He decoded nine WSPR stations including WI2XBQ at a distance greater than 4000 km.   Al was decoded by forty unique stations.

Rick, W7RNB / WI2XJQ, reports that he finally observed a return of reports that were East of the Mississippi river after a late start.  He provided reports for nine WSPR stations and he was decoded by 28 unique stations.  Rick’s unique report details can be viewed here.

Joe, NU6O / WI2XBQ, reported, “A very good session. Heard by 29, 11 2500Km+, 5 3500Km+. Prop to the E coast was all one way, W-E. I did hear both XIQ & XXM, both at 2500Km., a single hop.”

Dave, N4DB, reported, “Once again back up to 10 heard, on better days in Dec it was usually 11 or 12. Think missing are the VE7s”

Mike, WA3TTS, reported, “…the path to PNW was somewhat open for me.”  Mike provided the following statistics and comments:

“No XGP decodes prior to 0514 and Eric XJM was hearing XGP an hour or two earlier.  I had a longer time constant power line noise which my blanker could not completely handle for the first half of the session. The noise seemed to be the kind that occurs when dew starts forming on either the lines or insulators.  The noise most have abated later on in the morning to manage 51 decodes and a best -7 from XGP…..

My NE/SW EWE antenna has been temporarily repositioned at about 65/245 degrees.  It also is a bit shorter in horizontal span, perhaps 55 ft vs. 70 ft, but the height is around 18 feet  I will try this EWE antenna orientation for a while before I decide if it is worth going back to the 45/225 degree position, as that will require a support post (Power company took the tree out for line maintenance/protection)”

Ron, NI7J / WH2XND, reported that he was listening to the Northeast with the modified K9AY loop system but provided a few reports for ZF1EJ through what might have been an enhancement from the elevated geomagnetic conditions.  He provided reports for eight WSPR stations.

Trans-Pacific openings were down, which seems to happen quite often when trans-Atlantic openings are up.  Report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, posted links to two tables showing VK -> total JA DX  and VK -> JA peak S/N for the session.

Roger, VK4YB, reported, “Higher QRN and poorer propagation but WH2XGP and WH2XXP still managed to get through. VE6XH stats: 160m 8 spots, best -11, 630m 4 spots, best -25.”  Roger received reports from JA3TVF, JH1INM, TNUKJPM, and VE6XH.

Ward, K7PO / WH2XXP, received reports from 65 unique stations including VK4YB.

Larry, W7IUV / WH2XGP, provided reports for twelve WSPR stations and was reported by 59 unique stations including VK4YB and ZL2AFP.  As W7IUV, Larry provided reports for eleven WSPR stations.  Larry indicates that a review of the WSPRnet database indicates for his call sign, 184 unique reporting stations provided reports in the previous thirty days, indicating high activity.  Larry also noted that over the previous thirty-day period he decoded 31 legitimate WSPR stations as WH2XGP.

This was a great session for domestic openings.  The previously reported CW QSO’s with WG2XJM were a nice highlight.  Its not often that we have such stable band conditions for such a long chat and low noise helped a lot.  WSPR reports were very good and my reception reports were improved over recent sessions.  Those can be viewed here.  My transmission reports were normal and it helped that activity was high, including several new receiving stations.  Those reports can be viewed here.

Merv, K9FD/KH6 / WH2XCR, was absent during this session.

As we approach band implementation under Part-97 rules after the recent release of the Report and Order, there seems to be quite a bit of planned band activity.  I’ve spoken the a lot of people via e-mail over the past week and if I try to chronicle every detail of each session, it may become a full-time job requiring its own staff to complete each day’s report.  Time will tell.  I would be interested in hearing your thoughts and ideas.  Do I raise the bar, changing the minimum reporting criteria?  What rubric is used to make that determination?  Thanks for your input!
