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.

Ultimate3 WSPR kit - short review including frequency stability and GLONASS support
Sorry in Russian only - http://www.ra3apw.ru/wspr-ultimate-u3/

Karen, ra3apw

I caught an interesting false decode today. Details here:
http://david-g0lrd.blogspot.co.uk/2014/08/wspr-false-decode-curiosity.html

For some reason, I seem to be hearing a lot more than anyone else. This is a sufficiently strange phenomenon for me that i thought I would share my kit with others - particularly G8DYK, G4BOO, PE1MPX and OZ7IT.

I'm using a IC-756 Pro III set at about 5W into an SGC MAC-200 ATU which is handling a long wire. No idea how long, but it runs down the side of a small field, in the hedge. It's about 10m high at it's best point, which is in a tree, followed by a long, sloping section. It's not great, but it is straight.

WSPR 4.0 r4229 works fine in ubuntu 14.04 trusty 64 bit PC

now testing a rotary fipole at 5m asl from PKW.
TRX Flex3000 5W

I left my station on WSPR 30m all night. My Hustler 20m coil was extended with a 50MHz 1/4 wave whip to make it work on 30m. I was spotted in Ontario and USA East Coast on paths 2000 to 4000 km. Not bad for +13 dBm (0.02 W), and the antenna is less than 3 meters long.

A simple field strength check shows the 6m whip is a few cm too long. Thus I am off-resonance, and my SWR is probably high. Nevertheless this 30m "kludge" seems to work.

How does the UK operate on 2m?

** Horizontally or vertically polarised?
** 144.492 dial?

I've spend some time, today, vertically on .492 and heard nothing. I'd have expected to hear one or two people who were on today :-(

Hello
my WSPR hardware info site.

Certainly interesting. I ran for most of the afternoon on a long wire from an ft-897 running at 37dBm, and collected a couple of G-stations.

I swapped to a TS-2000, 37dBm, using a home brew off-centre fed dipole which is (I know) quite a lot better than the long wire on every band except top band. I'm now into IK, HB, EA...

Trouble is there is more than one variable here. So no conclusions!

Animo para todosmlos que quieran hacer digitales esta noche en 20m

[Update: So far only a single decode of G3NR. Anyone else want to try sending some 2m WSPR my way?]
[Rx active 24/7 - 144.492MHz dial ; JO02AC near Cambridge, UK ; vertical, omnidirectional)

I carried out the official Kenwood mod to reduce frequency drift, but not noticed any improvement. It could be that the capacitors I used do not have correct characteristics to compensate for temperature changes or that the rig may be too old to provide the kind of stability that WSPR requires.

running 2 watts to ocf dipole deployed in to a pvc fence top 5 feet agl. have rec'd 3 spots here all ready. 73 have a blast with the wspr net. de w8box sk

Today, at my sunrise i spotted our friend George: 2014-08-09 03:44 K9PAW 1.838193 -30 0 EN61ar 1 F59706 JN07th 6723
This first NA station opens my new season and my Rx Challenge. The goal is to spot (Rx) the greatest number of UNIQUE CALLSIGN of North American station (W and VE). The previous season I had reached the number of 39 unique callsign. I'm using the same antenna system (2x Wellbrook ALA100 loop) and wires configuration for the new period.

All:

NH7J, Gus MacFeeley, in between tropical storms in Hawaii, just placed KH6UL WSPR Beacon back on the air.

The original beacon was updated with new DDS-60 Module, 160 - 6 Meter LPF / Control board, higher gain PA and Gas Tube protection.

Six meter transmit, 17 dBm, at 4, 24, and 44 minutes past the hour.

The beacon is on the West 22 Element Vertical Log periodic antenna.

Switched from 40m to 80m at 09:00 GMT

now testing new 95m long delta-loop on 40m and 80m

Am I really the only person in the UK on WSPR 144MHz? :-(

And one of three in Europe :-(((

Sitting on 160m tonight.

Enough WSPR activity to suggest the band is open to France and Denmark (from the UK).
Switch to JT65. Dead. Clearly lots more people sitting on WSPR, and no-one in QSO-able modes.

:-(
