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

Current Operating Frequency and Mode

OFF AIR but hope to be back by 1115z Saturday morning if I don't oversleep

Stormy terrestrial and space weather conditions impact many stations but some are rewarded for efforts; KHP receive WSPR2 – Maybe K6KPH QRV soon?; Good openings for VK4YB to Japan; K2BLA reports first 630m DX with ZF1EJ JT9 QSO; Opening night in US for everyone else is tonight! Don’t forget about the JARL’s 630-meter awards program!

The details for October 15, 2016 can be viewed here.

The UTC amateur registration database is here.  

HERE are a  few mode specific comments addressing where modes are located now and probably where they are best placed in the future

Blog administrative note:  As we transition to amateur activity on 630-meters, more of my focus in this blog will be on two-way QSO highlights.  I have not yet decided how this transition will impact WSPR reports long term but I will more than likely begin including WSPR summaries rather than specific operator details for WSPR reports.  The next few weeks will help me make that decision.  Thanks for your patience as I make adjustments.

 

The image tells the whole story.  It was noisy for many as another cold front is draped across the US which should finally bring persistent cool temperatures to much of the country.  Hopefully with cooler temperature fewer lightning-rich storms will be active in the long run.  Mexico and the Caribbean into the Atlantic also remain hot spots for lightning noise.

11-hour North American lightning summary

 

Geomagnetic conditions continue at storm levels but the general trend has been towards improvement compared to previous sessions.  The Bz continues to point to the South and solar wind velocities are beginning to trend downward as well, averaging near 590 km/s with isolated period above 600 km/s.   DST values were trending toward the centerline at negative levels but an additional Kp spike to G1 storm levels sent values diving again.

 

 

 

 

Just a reminder that the JARL sponsors an 630-meter award for paper chasers.  Details in English can be viewed here.  Let’s support this award!  Others may follow!

Reverse beacon network reports for the session follow:

 

Doug, K4LY, reported that he completed a CW QSO with N4PY just before sunset when noise levels increased significantly.  He also operated FT8 and WSPR but reported a problem with his system sometime overnight.

PSKreporter indicates the following JT mode activity on 630-meters during the previous 24-hours:

Ken, K5DNL, submitted this table comparing JT modes by tone spacing, detection limits and bandwidth:

Ken also reported that he completed JT9 QSO’s with ZF1EJ and K2BLA and tried a QSO with VE7VV that was unsuccessful.  Ken indicates that thunderstorms and associated noise made the operating session very difficult.

Al, WB0DBQ, indicated a reception of a unsuccessful JT9 QSO attempt between VE7VV and K5DNL:

1058 -12 -0.0 1361 @ VE7VV K5DNL -27

Similarly, Ken Miller, N8CGY reported CQ’s from K5DNL on JT9:

1138 -21 0.1 1341 @ CQ K5DNL EM15

Phil, VE3CIQ, reported that he called CQ with FT8 and JT9 for a bit last night but heavy rain in his area brought an end to his session.  He completed no QSO’s.

Neil, W0YSE/7, provided this transcript of JT9 activity received at his station in Vancouver, Washington overnight.  Neil also noted the success of Glenn, N6GN / WJ2XBZ, in Santa Rosa, CA who is operating at 20 mW ERP (or possibly EIRP).  Neil submitted the datasets illustrating Glenn’s reports in Vancouver in addition to his overall unique reports for the session.  For those that don’t believe that they can get a station on the air, let Glenn’s success be their model.

Another very simple but historically effective system is that of Roger, G3XBM.  Roger submitted these comments about his improved earth electrode antenna system and intent to be QRV during tonight’s session as well as a few statistics from this session:

“My earth-electrode “antenna” for 630m has been repaired and the secondary antenna current reading on the Marconi has gone from 17uA to 22uA using this as an additional ground.  It remains to be seen (tonight) if this small ERP increase makes any real difference. The next thing to try will be more/better grounds directly outside the shack and some radials?

I shall be on 630m WSPR (20% TX) this evening and overnight. The ERP is still very much QRPP (low mWs). All reports welcomed.

I know this is trivial compared with the results obtained by “real” stations, but it shows useful results can be obtained on MF with a very modest installation. My hope is this encourages others.

Last  night my ultra simple system got 3 unique spots on TX and I spotted 10 unique stations on RX.”

 

Frank, W3LPL, took his maiden voyage during this session using a rather impressive antenna system at 200 mW TPO from a barefoot WSPRLite.  His antenna, a 200-foot tall inverted-L, has 310-foot of horizontal section and 30,000-foot of radials associated with his 160-meter four square array.  He expects to only need a few watts to reach maximum EIRP and is seeking an amplifier to accomplish 5-10 watts TPO.  Frank received reports from 24 unique stations, mostly in the eastern region.  I expect his range increases significantly as band conditions and propagation improve.  Frank expects to listen with a receive four square array and may implement a larger system later if he can borrow enough adjacent farmland for the installation.  He expects to be active on CW and digital QSO modes later this season.

W3LPL session WSPR activity

 

David, N1DAY, indicates that he provided reports for eleven WSPR stations and he received reports from 35 unique stations including fourteen stations that were further than 1000 km distant.

Rick, W7RNB / WI2XJQ, provided reports for six WSPR stations and he received reports from 22 unique stations.  Rick’s unique report details can be viewed here.

Mike, WA3TTS, reported that he decoded thirteen WSPR stations overnight, including “… including 3 XCR decodes in high noise conditions with storms in W9 land. W8RUT and K9SLQ continue to be decoded in daylight conditions in the -12 and -24 SNR range respectively (243 and 436 km paths)…”

Mike added that he “…ran the NE and SE EWE antennas early on 630m for noise management and e-probe on 2200m with separate converters for 630 and 2200m.  Around  0430 the QRN started to subside a bit and I decided to run the single SW EWE antenna into an LF/MF-capable hybrid splitter and then into separate converters.”

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, indicated at 1400z that he “…switched to the JA beam at 11.58 with great results. Going QRP for the rest of the session.”  Roger received reports from JA1NQI/2, JA1PKG, JA1PKG/2, JA3TVF, JE1JDL, KPH (first time report), KR6LA, TNUKJPM, VE6JY, VE6XH and VE7CNF.  He shared two-way reports with WH2XCR.

Jim, ZL2AFP, received reports from VE6XH, VE6JY and WH2XCR.

Coastal station ‘KPH’ is getting in on the 630-meter action, providing reports for eleven WSPR stations during this session including VK4YB.  I’m excited about the prospect of hearing K6KPH on the air running CW soon!  Details of the historic station are available at radiomarine.org.

KPH 24-hour WSPR activity

 

My session was limited to the evening due to overnight and early morning storms and focused on CW.  Band conditions were noisy, even worse than the previous session, although the West was significantly quieter than the East.  I spent a lot of my time listening for W0RW who was calling CQ on 473 kHz before securing the station for the night.  That is a path that is often very open but that was not the case this time.  Paul indicates that he will be back tonight.  I hope to be back on the air tonight as weather moves East this morning.
