Noise was elevated in North America from storms in the Caribbean, through Florida and into the southeastern coastal region. K2BLA reported that he was off air during this session due to storms and associated noise. A number of evening storms were located in central Mexico and also in the Pacific, West of British Columbia. A few isolated early storms were present in Central Japan and Oceania continues to struggle with a number of large storm systems. Yesterday VK4YB indicated that the forecast was not favorable for listening.
Geomagnetic conditions were quiet. The Bz is pointing to the North this morning and solar wind velocities are averaging near 350 km/s. DST values were variable and at positive levels.
Like the previous session, the band was open on domestic paths but elevated noise impacted activity. Trans-Atlantic reports were down, probably do to noise but openings remain plentiful. Trans-Pacific paths struggled, probably due to storm QRN in and around the Pacific Rim.
Rob, NC0B, submitted this comprehensive analysis entitled “Dynamic Range tests of WSJT X and WSPR on 630m using AGC with IC-7300”
Rudy, N6LF, reported on the 600 meter research group email reflector that he has reposted chapter 6 of his book on the topic of inductor design for MF and LF antennas. Rudy’s website can be viewed at http://www.antennasbyn6lf.com/.
Reverse beacon network reports follow:
The following stations provided reports of their two-way QSO’s and/or any additional activity that might have occurred during this session (this is not necessarily a complete list – only what was reported!):
John, WA3ETD, completed JT9 QSO’s with K9KFR, WB4JWM and K3MF. John heard W7IUV twice, best at -23 dB S/N, but there was no two-way contact as Larry was not hearing him, indicating that he “…never saw a thing here, RX condx were weird, WSPR RX was pretty deaf at that time also…“
Robert, KR7O, “Lightning crashes have returned, but conditions still improved compared to the previous session. Low JT9 activity but did copy K9KFR and K9SLQ CQing. I had a partial contact with K1YQP. Sent report for about 20 minutes, but never received an RRR. Was copied by 16 on WSPR. Copied 24, including TC stations N4WLO (9/-24), KC4SIT (58, -20), K4LY (-26), W3LPL (15/-24), VE3CIQ (-28), W4BCX (8, -23), W1IR (19/-24) and ZF1EJ.
ZF1EJ – 3 spots, -25
KL7L – 3 spots, -18 before he went QRT
VK4YB – 11 spots, -26“
Ken, K5DNL, operated WSPR overnight, reporting 25 stations and received reports from 85 unique stations including KL7L, G0LUJ, G8HUH, EA8BFK, ZF1EJ and eight Canadian stations.
David, G0MRF, reported on the RSGB-LF reflector that he “Saw a very nice peak in signals last night on 630m. One WSPR transmission at 05.32 was received by: N1BUG, W1IR, KA1R, K3MF, N3FL K4LY/P W4BCX and ZF1EJ. Also nice to see LA3EQ calling CQ on JT-9 around 04.00“
Most activity at KB5NJD was early, including a daylight QSO with KE7A about 30 miles to the North of my station. Richard was checking out the station on CW working to align both the transmitter and receiver. He is using an inverted U that is about 30 foot tall and strung between the trees, comprising of 500 foot of wire. He uses a transformer at the feed point to match to coax. He made no mention of radials but I presume that some were present. In the early evening I worked AB5S, located about 45 miles to my Northeast. Dave was copyable but weaker than our previous QSO. He continues to use an 80m loop with no loading or matching. At this point noise was very high and any callers would not have been heard so I QRT’ed. There was no morning activity from my station.
