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

Another average session after early evening M-Flare in North America; Fewer active stations and higher noise level during this session

– Posted in: 630 Meter Daily Reports, 630 Meters

Active stations were just trying to get through this session it seemed.  The band offered a slow start with opening occurring at the more typical, later time compared to recent early openings that created some curiosity as far as Summer sessions are concerned.  Being a Summer weekend in the northern hemisphere, people do travel and I suspect the vacation season is having an impact on in-shack radio time while portable activities, most notably related to the ARRL’s National Parks on the Air program, seem to be flourishing at the moment.

A late afternoon / early evening M-class flare was reported during the session and in spite of waning daylight, the D-layer absorption map indicated impacts to the central and western portions of North America.  This activity may have caused the perceived late start during this session.  Solar wind was elevated through much of the session although this morning the values have decreased to levels below 400 km/s.  The Bz had been pointing to the South through much of the session but has since rebounded to the North.  The Kp levels continue at mostly quiet levels:

Ken, K5DNL / WG2XXM, reports that he decoded three WSPR stations and was decoded by fifteen unique stations overnight including seventeen reports from VE7SL, best at -20 dB S/N, and 28 reports from WH2XCR, best at -21 dB S/N.

Roger, VK4YB, reports that he is testing a new antenna system consisting of a pair of 100-foot verticals spaced 240-foot apart, fed at the top of each vertical, each out of phase with respect to the other.  He reports his noise floor is -80 dBm on either single vertical or combined and wonders what the theoretical values should be.  Modellers, can you help Roger?

Neil, W0YSE/7 / WG2XSV, reports noise conditions during this session and offered the following statistics:

Hearing only these: VE7SL, WG2XXM, WH2XCR, WH2XGP

Heard by:
N6RY only 1 time at -29,
NO1D only 1 time at -29 also
and, VE7SL, WH2XGP many times”


Phil, VE3CIQ, reports thunderstorm conditions in his area but he did decoded WG2XXM and was decoded by WI2XFI using WSPR.

Larry, W7IUV / WH2XGP, reports very high noise levels at his QTH where me decoded six WSPR stations and was decoded by eleven unique stations.

Regional and continental WSPR breakdowns follow:

NA 072316

North American 24-hour WSPR activity


EU 072316

European 24-hour WSPR activity


JA 072316

Japanese 24-hour WSPR activity


VK 072316

Australian 24-hour WSPR activity


There were no reports from the Caribbean, trans-Atlantic, trans-African or trans-Equatorial paths.  UA0SNV was present during the session but no reports have been filed from his station at this time.

Laurence, KL7L / WE2XPQ, was off line during this session as he has a station rewiring project in progress.

Merv, K9FD/KH6 / WH2XCR, had pretty good conditions through this session, reported VK3HP for the first time in quite a while and two-way reports with VK4YB.  VK2XGJ continues to hear Merv well also.  Normal reports for North American stations continue.
