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.

Intermittent line noise that I need to track down on receive. Transmit seems to be working good so far. Dipole is at 10 meters high.

I got my call sign (SV1CIF) in 1993, was born in Agrinio, where he lived until 2010, Agrinio is a small city with about 100,000 people in Western Greece. About 300 km from Athens, where I live now I am active in most of the amateur bands. I really like the hobby, the radio, and this is my main hobby since March 1993 I love to collect QSL cards. Always reply 100% all cards can reply directly papers the same day. Can I use LoTW (mostly) , QRZ and eQSL

QSL policy:

I'm normally running KiwiSDR with vertical whip tuned on 2,200m.

I added a 200 mW BS170 amplifier onto the end of the Si5351 and, lo and behold, the little thing can be heard on the west coast, and also in the Canary Islands.
I can only imagine what would happen if I could get the antenna a little higher off the ground.

Ham radio is cool!

I'm now using a ft817 and a 10db attenuator giving 50mw. Some Antenna swapping including EFHW Verticals

Today K8KSM heard my Raspberry Pi WSPR beacon. This is the first time someone in my same town has heard me. The previous shortest distance was almost to Cleveland (~ 100 miles away) ... So, I had been suspecting my random wire had properties that made it bounce up higher before going anywhere so most of the reception was from the signal traveling in the upper atmosphere. The usual close reception is Indiana or Michigan on 30 meters.

I added power levels to the transmit and receive station summaries. Each combination of callsign, 4 or 6-character grid, and power level (if transmitting) is counted as a separate station.

Transmit summaries for each different power level used by a station. Multiple bands grouped together then sorted by distance. Shows number of different reporters and total spots.

I'm reading on the web (QRZ, QRZNOW, EHAM, etc.) about the amount of digital on the air these days and how it's getting loud and crowded on 20 & 40. What say we start really working WSPR on the WARC bands? They're waiting to be lit up as much as good old 20. 17 during the day and 30 at night?

Created a dedicated Ham shack in a spare closet. I have very little equipment, but at least it's got a home of it's own.

Lesson: Never upgrade the Kernel of the Pi while WsprryPi is running. I had to wipe the SD card and rebuilt it. Fun.

I upgraded the Raspberry Pi Linux, and now WsprryPi lockks up on transmit. Will fix... in my spare time!

5mW on 40meters never ceases to surprise me. I started the machine this afternoon and will leave it for a week or so.

Finally have WSPR Rx capabilities up and reporting from QTH FN42fj.
