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.

Has anyone noticed this before? The database does not seem to upload spots at 0000 UTC from WSJT-X

Today's lonely decode on 10 meters with poor conditions. Still amazing though.

Now running red pitaya with WSPR software.

73 de ON3VNA

Beacon operates on bands 80,40,30,20,15m. Output pwr 0.2w.

Last spot on LA9JO!

Trying out my new 7300 with 2% power. RX seems very good.

First attempt at WSPR on 40m and 5w.

JI1CBW appears on LF WSPR-2 after Oct. 30th 2016.

Many thanks to all those that viewed the receiver design on my blog.
I have now posted a compatible VOX controlled WSPR transmitter.

Best 73 to all.

Has been QRT for several months, just got lazy and overworked.

Finished moving to a new apartment! I have unpacked my HV-5S, FT-817 and SCU-17. I was disappointed after checking my setup last night and this morning. S8 noise on the bands supported by the HV-5S (40mb, 15mb, 6mb). Sheesh. Noise was tolerable in my previous appartment.

Antenna is indoor (attached to a tripod) since now I have no veranda. :-( Apartment is made of wood so indoor made sense to me.

I've got old JRC AC line noise suppressors on the outlets that I use.

Sorry, all my spots from 0210-1136Z reported on 20M were actually 630M spots. Please correct the database. Thank you and 73


My station will be monitoring 10 meters every weekend.

Sorry again for another band error. All spots reported from 28 october, 16:00z were on MF band, not LF.
