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

Quiet but elevated geomagnetic conditions give way to an average to below (recent) average session; A pair of trans-Atlantic reports for EA5DOM; JA0GBO transmitting and creating some excitement in Japan

– Posted in: 630 Meter Daily Reports, 630 Meters

Band conditions were curiously quiet through the overnight period with noise levels in the southern US ranging between S1 and S5.  With active on-going precipitation events in the Midwest and parts of the East, however, its likely that not everyone shared the same low noise conditions.  Notable was a band peak between 0500z and 0800z, at least at my station, where a number of strong, persistent S/N reports were observed.  That’s not to say that other periods were not useful.  Quite to the contrary, JT9 levels were observed for a variety of stations throughout the session.

Low geomagnetic activity from the previous session gave way to a slightly elevated Kp, but the Bz was generally North-pointing and solar wind velocity remains in the low category.  X-Ray flux is currently at C-class levels.

Phil, VE3CIQ, reports a session that was a carbon-copy of the previous with WH2XGP appearing at sunrise in VE3.

John, WA3ETD / WG2XKA, reported an average session with several two-way reports with WH2XGP on the transcontinental path.  John notes that signals were sufficiently strong for the presence of the “hybrid phantom” decodes that occur when multiple strong signals mix, resulting in a new call sign being generated.  Local strong stations also led to John adjust his “decode depth” in the software in order to avoid decodes of  harmonics from those stations.

Ken, K5DNL / WG2XXM, reported that he decoded twelve WSPR stations and was decoded by 36 unique stations during the session.  He also notes that he decoded two VE stations and was decoded by six VE stations.

Neil, W0YSE/7 / WG2XSV, reported that his 200 mW daytime ground wave signal continues to yield reports (-24 dB S/N) at meridian noon (1:48 PM PDT) at VE7SL.  He also notes that the reports remained near the same level through the day and into the evening.

WSPR activity appears to be high, although a formal census was not taken.  Around 0200z, approximately 84 MF WSPR stations were observed.  W8OTR was originally flagged as a new station but after further investigation its believed that this stations has provided reports in the past on a few occasions.

JA 041016

Japanese 24-hour WSPR activity


Note that JA0GBO is creating some excitement in Japan with a significant number of stations listening during the session.  Its my hope that the recently announced JARL award will continue to increase the amount of activity in Japan.

There were no reports from the trans-African path.  UA0SNV was present from Asiatic Russia during the session but no reports were found in the WSPRnet database.

WD2XSH/17 reported EA5DOM twice on the trans-Atlantic path.  Its been a while since we have seen the lower latitude path being present without the higher latitude path.

Eden, ZF2EJ, took advantage of good, quiet band conditions and provided reports for a  number of stations around North America.

Merv, K9FD/KH6 / WH2XCR, experienced a pretty good session, with a few reports into Japan and two-way reports in Australia with VK4YB.  John, VK2XGJ, reports that overnight activity was low during this session in Australia and he was not sure why.  Merv’s reports into the eastern US are also noteworthy, with decodes at WI2XBV and WG2XJM (two-way reports).
