The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.

Impressed by frequency accuracy

I've been very impressed by the high standard of the frequency reporting I'm seeing. Great job there folks!
Here's a good example (I transmitted on 14.097192 MHz, referenced to a GPS disciplined oscillator):

160m again superbly active during the EU sunrise

Yes really active. This morning between 04:08z and 06:04z no less than 50 dx spots "across the pond" with an beautiful and constant propagation, clean traces without qsb or qrn.
10 stations have benefited from these conditions and of course there is still room for new entrants during this magical time of sunrise. So come on guys,...

By my side, 6 NA stations spotted with a new one K7EA (Richard), bringing my Challenge score to 8 since aug-24/2013.

NA Callsign listing (pwr): VA3MW/P(5w), W1FVB(1w), WB5WPA(5w), VE3SWS(5w), K4RCG(5w), K9PAW(1w), K9YWO(1w), K7EA(5w).

My score is probably close of Tom (G8HUH), the best ears in central europe.

Thank you to all , the new season is well underway ; GREAT!!

WSPR beacon on 80m for the coming nights

Hi,

I will be running my WSPR standalone beacon with less than 1W to an OCF-Dipole for at least the next 7 nights.
Already received reports from VK6XT and NH7SR so it is working ok...

Active EU Greyline on 160M this morning

Despite average conditions 160m is currently attractive in EU. This morning around 38 stations on air (tx-rx).
25 dx Spots "across the pond" during greyline from K9PAW, K9YWO, VA3MW/p, VE3SWS, G8HUH, F6CNI, G3ZJG, F59706.
Congrats to John (G3ZJG) for "two-way" contacts with VE3SWS and VA3MW/P- Rarely seen at this time frame.
By my side, I hope to hear and decode Laurence (KL7L), recent WSPRer but yet very active.
One word to say "AGAIN,.."

G0PKT: Martello Tower Group QRV on 10m WSPR

Back in July I posted an entry to advise that the Martello Tower Group are running a WSPR beacon on 30m. We've received a lot of reports and initial indications are that it's a useful beacon to have online.

As of the 17th September we are also running WSPR on 10m using 300mW to a 5/8 vertical on top of the Martello Tower.

Hopefully this beacon will help with propagation testing on 10m and the fact that it's an 'always on' signal may persuade a few extra people to switch to 10m for a while to look for it.

As always, we look forward to reception reports and we hope that WSPR users will benefit from our 10m beacon.

At the time of writing, 10m is open from the UK to the USA with some good signals being reported.

MF station details

This may, or may not, be of interest!

The antenna is a horizontal wire, about 80m long and 15 meters high, sloping down a little at the ends. The down lead of approximately 10 metres couples into a variometer matching unit and is tuned against a ground mat of 20 ground rods placed over an area of 100 m2. The estimated ground resistance is 11 ohms and the antenna radiation resistance calculated as 0.33 ohms. The overall set up has therefore an efficiency of 2.9%. My transmitter currently produces 50 watts output and therefore the erp is estimated as 1.45 watts. I round this up to 2 watts to be safe and this is what I declare in the spots.

I do intend to build another smaller transmitter to produce an erp of 0.1 to 1 watt and will run this later.

160m tonight

I will be trying my 8 Band Buckmaster OCF dipole and 1 watt tonight.

Setting up

Well by the end of the Month i'll be dipping my toes into digital modes, have already installed JT65, 9 and WSPR software to the laptop and my folks are getting me this for my birthday, http://www.g4zlp.co.uk/unified/DM_MiniPRO.shtml I'll be using it initially with my 857D and then my Icom 718 (once the 40m mod is done!)

An apology.

I want to apologise for incorrectly posting 6 meter contacts when in fact they were 30 meter contacts.
Seems my PC and FT847 stopped talking to each other. I do not know what can be done to correct the data base.

Sorry for any inconvenience. Cheers, Dick

20m Vertical Today

I will be testing my 17' Vertical at 1 Watt on 20m during the day today (9/16/2013) using Elecraft K3 and SignaLink. My location is FM18qt south of Annapolis, MD and west of Washington, DC.

I will take matching heard/hearing contacts and upload to LoTW during the week.

Mike (VA3MW) is back in 160m

After the windstorm that broke his previous antenna, Mike is back last night with a "160m full sized vertical". I try to imagine !!
Despite poor conditions, Mike is the only one NA station crossing the pond and now take place in my 160m challenge list with 1W.
In the night Jaap (PA0O) had opened the way.

New DDS WSPR machine

I've just made dedicated 20m WSPR machine.
Using AD9850 dds and its 125MHz clock is GPS disciplined.
TX final is 2SC1306 so, power is maximum 3W.
Now, I'm testing on the air.

Will test 6m WSPR today

I will test 6m WSPR beaming to south at around 10:00z.

Crossed Field Loop R.I.P.

The last few days (Friday to Saturday) has seen a very bad rain storm, hitting my part of the U.K. infact our village was cut off for some hours due to flooding.. At some point during the storm the CFL died .. I think it was water ingress into the matching unit, I will carry out a post mortem when I can get the aerial down to ground level, in the mean time running I'm running a small HomeBrew active aerial at ground level RX only.
Regards Paul.

WSPR Qso mode

hi Jay VE3SWS-

Very good on the "real 2 way" qso mode! It was popular a few years back, but slowly faded away partially due to the long transmission sequences.. If you don't mind trading in the 5.9hz width sigs for something slightly wider- take a peek at the semi-new mode in WSJT-X ver2 called JT9-1. This popular 2 way qso mode's sigs have a width of 15.6hz, and a transmission time of 50 seconds.

WSPR 2way q's were typically found on jt65a channels, with a df around +300.

You can find JT9 sked activity on "obriensweb.com/lotw", and "Hamspots.net/jt9".

I'm open for JT9 or WSPR 2way skeds, just shoot me an email.
