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.

According to the latest user manual the new FST4W modes should provide enhanced capabilities not only in the LF/MF region but also 160m. Regular activity is now well established on 136 and 474.2 using FST4W with some excellent transatlantic spots when conditions allow, so perhaps its time to see what can be achieved on 160.

There was some initial activity on 160 (and higher) when the modes first became available but appeared to die out after a few weeks.

My first time operating HF in the field was this past weekend, 12/6/2020. Daytime on 40 meters out of the back of an RV with LiFePo4 batteries. Power was easy. Without a mast though, getting the antenna high enough off the ground was impossible. I found 7.192.00 busy with a SOTA activation. Operator was N3BZ on Mt Doom, which I have no idea where that is, and without the SOTA call sign I'm left to guess that the general region is in Arizona. I was in Moab, UT. His station had to have been qrp, but came in clear at 5 and 9. I made contact with him, and it was my first hf contact.

Hi all.
I am running a Black Friday Sale fora few days so if you want to get a standalone WSPR transmitter this can be a good opportunity to do that.
Check it out at

THE SALE IS OVER, thank you to all that participated!

The WSPR server is very busy. The site is very slow.
I've started my WSPR receiver and WSPR 2.12 software for decoding, but only one by ten decoding cicle can reach WSPR server! Many spots are saving only in my PC! WSPR 2.12 write: "Could Not connect to WSPR server" e.t.c.
So many beacons are working continuously. Maybe we must limit beacons activity?

18 november 2020.
In Minsk-city(Belarus) a weather today is -3C, and first snow in this 2020 year!

TESTING NOW: Wendelantenne Helical antenna - bamboo cane 1.5m long for 40m - abt. 15m Wire - Home Brew

My QRP-Labs QCX works well in WSPR beacon mode with the external GPS receiver unit. However, it has consistently generated a frequency drift reported by receivers. There has been some discussion on the QRP-Labs forum about this, and the FETs do get warm when the unit is transmitting.

For the last year I have been running a Wellbrook ALA100LN preamplifier driven from a 8m x 2m wire loop for LF to 6m. Because I am close to a MW broadcaster 9 pole HPF and 9 pole LPF are used to remove the 0.55-1.6 MHz signals ( 1/2 V rms antenna output !! ).

Many experimental report for antennas and other electronics devises in my blog. All are written in Japanese originally but may possible to see using Google translate.

Presently back on sloping 40m. loop @7m.

See the description and how to access this free program my the General forum posting. Search on wsprpath. - AJ8S

My first time on the wspr in a few years. I started at 5 watts and updated to 100 watts will run about an hour today

As the September Equinox is on the 22nd, it might be a good idea to get the yagis facing those on the other side of the equator. Probably a slim chance, but you never know with WSPR.
I'll have my yagi beaming in the European direction during my afternoons at least over the coming week.

Remember to check into the 50 MHz WSPR Group page on Facebook and let us know what your up to on 6m WSPR.

Currently experimenting and comparing a 1/4 wave 40 mtr. fishing pole vertical with two tuned radials abt. 60cm off the ground against the usual full wave 40 mtr. horizontal sloping loop antenna at 8 mtrs high.
