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

Current Operating Frequency and Mode

QRT but I'll be back tonight, WX permitting

SCHEDULED ACTIVITY: CQ 474.5 kHz CW by 1000z through sunrise most days, WX permitting

The best propagation night of 2015 (so far!)

– Posted in: 630 Meter Daily Reports, 630 Meters

Ok sports fans, pack a lunch and plan on staying for the day because this is going to be a long one.

First, at one point last night there were 79 WSPR stations on 630-meters.  There were less than half of that on 160,80,40, and 30-meters and only a few more on 20-meters than on 630-meters during that observation period.  That level of activity is amazing and what we have been waiting for.

I think it was Laurence, KL7L / WE2XPQ, that said the map looked like 20-meters in the summer.  I tend to agree.


24-hour WSPR map. Note the level of trans-Atlantic activity through this session.

Jim, W5EST, generated a break down of each station, including the number of reports for each and the peak S/N as a summary.

W5EST 100515Jim also includes an hour-by-hour breakdown and some additional comments about the session:

W5EST hourly 100515

“Timewise, the spots have these areas of behavior:

2245z: Sunset in Nova Scotia

2300-0130: DK7FC & then DJ0ABR reach VE1VDM & VE1HF & then W1TAG/1 overall rate 5/hr as evening sets in.

0130-0200: France, UK each make one cameo appearance at VE1HF.

0130-0230: VE1s peak with 19 spots/hr then dip to 4 spots/hr 0230-0330.

0130-0300: German stations reach New England at steady moderate 30/hr rate of decodes.
0300-0400: German stations reach New England and Pennsylvania in high volume: 62 decodes including some in VE1.
0400-0430: XJM and W1TAG/1 capture 7 spots of remaining TA from DK7FC and DH5RAE. No spots in VE1.
0539z: Sunrise in central Germany.
The information suggests an overall westward migration of the increase in decodes as they began in various regions. This makes sense because of westward motion of the terminator followed by decline in D-region absorption. However, a westward migration of the decline in decodes also apparently occurred as they came to an end in various regions.  This is harder to explain because TA ended more than an hour before the sunrise in Germany, and I won’t detain us with speculation just now.”


A significant number of screen shots follow from trans-Atlantic reporting stations.  These are grouped by the reporting station and show each of the DX stations that they heard.  There is really no simple way to present this information because there is so much of it.

Congrats to all of these stations for a very successful session.  Lets hope that there is much, much more of this type of activity.

In other news, Eden, ZF1EJ, reported the usual suspects, including WG2XKA:

In the Pacific, Merv, WH2XCR, saw the usual suspects including a single report for VK3ELV.  It will be interesting to see if the fewer number of spots is the result of recent geomagnetic activity or whether this path will become less prominent as we move closer to winter in the northern hemisphere.

Laurence, KL7L / WE2XPQ, was absent last night due to testing of his 137 kHz system.  He indicates that he hope to have both 2200-meters and 630-meters running in parallel during tonight’s session.

I had the pleasure of briefly working Eric, NO3M / WG2XJM, last night following my evening CW sked with Steve, KF5RYI / WG2XIQ/1.  Conditions were strong but QSB was varying wildly down here.  Eric indicated that he did not notice the variations as much but his signal was very near or in the noise floor, only to make a very large jump to a true 579 as we were signing.  That’s the way it always happens.  We considered a try later in the evening but Eric suspended transmissions in order to watch for Europeans as they approached sunrise.
