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

Current Operating Frequency and Mode

OFF AIR; QRT Thursday night but back Friday morning by 1100z

Geomagnetic storming continues but so do very good and numerous trans-Pacific openings

– Posted in: 630 Meter Daily Reports, 630 Meters

Another strong night of propagation was experienced in North America and across the Pacific.  Signals were strong and plentiful as were receive stations as WSPR participation numbers were in the 80’s by late evening, exceeding 80 and 160-meter totals by a significant margin.  Storm QRN spikes were reported after dark by several stations and it seems the active weather was located in the central US.

Geomagnetic conditions continue at storm levels with numerous additional spikes of the K-indices.  The Bz has been variable although is currently pointing to the North near 2 nT.  Solar wind velocities are approaching 700 km/s, averaging 675 km/s.  DST values are negative but perhaps not as negative as we have recently observed for such persistent storm conditions.  Is this why propagation hasn’t been much worse?

The highlight for this session was trans-Pacific openings which were numerous once again. Individual station reports follow:

Phil, VK3ELV, sent an email with his noteworthy decodes for early in the session that were not uploaded due to Internet problems.  Those can be viewed here.

Larry, W7IUV / WH2XGP, reports that he decoded eleven WSPR stations including VK4YB using the E-probe.  He did not decode any stations from the East coast.  He was decoded by 34 unique stations, including VK4YB and VK2DDI but not many stations in the eastern region of North America.  Larry adds that the path to KL7 was also very poor, likely due to high absorption which is logical given the amount of auroral activity currently observed.

Ken, K5DNL / WG2XXM, reports that he decoded seven WSPR stations and was decoded by 44 unique stations including seven decodes from VK4YB, best at -23 dB S/N.

Ward, K7PO / WH2XXP, reports that he was decoded by fifty unique stations including “VK4YB (-11), VK2DDI, VK2XGJ, and WH2XCR.”

Roger, VK4YB, reports that he has completed a new antenna, details pending, and within the first few minutes of operation, he decoded WSPR signals from WG2XXM,WH2XGP, WH2XXP and WH2XCR.  He also reported that he could see signals from VE7SL at 1204z and 1220z that did not decode.  Roger adds the following statistics:

“Spots 8*WG2XXM (-23) 24*WH2XGP (-17) 30*WH2XXP (-11) 1*VE7BDQ (-22) 8*WI2XBQ (-20) 48*WH2XCR (-13).  Hrd by XGP, VA7MM, VE7BDQ, VE7SL, KL7L, XCR”

Steve, VE7SL, reports that he decoded twelve WSPR stations including six decodes for VK4YB.  Steve was decoded by twenty unique stations overnight.

JB, VE3EAR, posted a 2-hour operating report to LOWFER that can be viewed here.

John, VE7BDQ, reports “Only running 100w TPO here, I see VK4YB rcvd me at 1210z -22 — Looks like I decoded Roger 6 times, best -17 at 1208z.”

Neil, W0YSE/7 / WG2XSV, was “receive-only” through this session as he operated two receivers and two antenna’s in addition to a “join.me” virtual receiver session.  He provided the following comments and JT9 data from VE7BDQ’s signal:

“Guys, attached is a copy of my reception of John G’s JT9 last night on two different rx setups.

The Vertical antenna fed the FT100d into wsjtx 1.6 (XP machine)
The Eprobe antenna fed the FT857d into wsjtx 1.6 (Win7 machine with “Join.me” running)

I had my “Eprobe” screen visible all night using Join.me and John was able to see my decodes of his signal.”

Neil also provided statistics for the WSPR receive-only session:

There were no reports from the trans-Atlantic, trans-African, or trans-Equatorial paths.  UA0SNV and ZS1JEN were present but no reports have been filed at this time.

Eden, ZF1EJ, had a nice night of receptions using two antennas and two receivers once again.  It continues to be noisy in the Caribbean:

Laurence, KL7L / WE2XPQ, continues to see reasonable results during this period of degraded high latitude geomagnetic conditions.  This is especially true right now as Laurence is “on the road” and recently spent a few nights under the Aurora in Iceland, now having moved on to the UK.  Here are a few details:

“Hi John – now in the Uk in what was 72 hours of the worst lf/mf condx ive seen for years – id put it down to a mixture of screened location, local smpsu noise which was put mostly undercontrol after the first 24 hrs but solar was the biggest killer on any path I looked at – deep fast and raspy signals on any skywave signal that dared be propagated near 500kHz –

oh well its all experimentation but I only decoded one jt sig during my TF sojourn and that was on 20m
