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

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

Trans-Pacific path between North America and Oceania shows quite a bit of life for a session that was reported by many as noisy

The details for June 29, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  Please continue to be patient and let the FCC finish their processes.  Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.

Noise sources were slightly less wide spread compared to the previous session.  The central region of North America was once again the focal point for storms but the East and West regions were generally in the clear.  The Gulf coast into the Caribbean and Mexico experienced considerable evening storm activity.  Noise levels here in North Texas were considerably better than the previous session, where I QRT’ed at bed time due to approaching noise.  Last night lightning crashes were spaced far enough, at least based on what I was hearing, that communications were not significantly impacted.  Propagation appeared to be average for late June although the lower latitude paths to Oceania from North America were improved.  It doesn’t hurt that activity in Oceania has really ramped up as they enjoy short days downunder.

11-hour North American 24-hour WSPR activity


Geomagnetic conditions are quiet.  The Bz has been moderately variable but is at unity this morning.  Solar wind velocities are averaging near 425 km/s.  DST values have also been riding the centerline near unity but have recently experienced a bit of a decrease  in late reporting periods.




Hideo, JH3XCU reported that the WSPR station located in Shenzhen, China using the name “SWL/SAILOR” is actually a Kiwi WebSDR remote receiver.  It can be accessed here.

John, WA3ETD / WG2XKA, reported that this was the first session in a long time that he was able to operate all night due to storms in his area.  He decoded eight WSPR stations and he received reports from twelve unique stations including VE6XH and WH2XGP.  John indicates that QRN was less than the previous session.

Mike, WA3TTS, reported “With the QRN in W9 land overnight I used my SE EWE antenna for noise management purposes until about 0630 utc, then switched to SW direction until SR.  Best DX was WH2XXP followed by ZF1EJ.  A total of 10 stations decoded overnight.  I also ran dual band 630m/2200m overnight, but no WH2XND decodes were made on 2200m band…”  Mike submitted the following details for the session:

Roger, VK4YB, reported that “The rain has arrived, but no lightning. Late sunrise spots on WG2XXM and WH2XXP (last at 27min after sunrise in Phoenix). No path to Japan again.  Edgar EJTSWL has reached Denham, WA. He is still rxing me best on my West ‘bottom hat vertical’.”

Ward, K7PO / WH2XXP, received reports from 32 unique stations including VK2KRR, VK2XGJ, VK4YB, ZL2AFP, and ZL2BCG.

Ken, K5DNL / WG2XXM, reported that he decoded three WSPR stations and he was decoded by 26 unique stations including VK4YB, WH2XCR, ZF1EJ, and three Canadian stations.  Ken indicates that the report from VK4YB came four minutes after local sunrise in Oklahoma.

Larry, W7IUV / WH2XGP, provided reports for four WSPR stations and he received reports from thirteen unique stations including ZL2AFP.  As W7IUV, Larry provided reports for six WSPR stations including ZL2BCG.

I started WSPR at 0226z for the duration of the overnight period.  While QRN was better than the previous session, it was still too high to continue the next phase of my receiving tests or for a pleasant CW session.  Reports overnight were reasonably good for 17% transmit duty cycle.  Most reports were at JT9 levels or near the typical reliable detection limit of JT9.  Reception was pretty good in spite of noise encountered due to my omni listening.  My transmission report details can be viewed here and my reception report details can be viewed here.
