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.

Were these reports indicating combination of TEP and ES?
It was regrettable that I couldn't send WSPR report to VK2KRR.

WSPR 28124,850 kHz
FSKCW 28000,850 kHz
CW 28280,850 kHz

je redémarre les modes numériques avec la même configuration que vous Michel KX3 et signal link pour l'instant je ne fais que de la réception . Comment paramètrer vous le logiciel wspr au niveau des port pour l'émission, utilisez vous le CAT enable ?
Je suis très friand de votre expérience le paramètrage des cartes son me pose souvent problèmes

I learned so much about radio propagation during last few weeks thanks to WSPR network. I think WSPR is also a good way to track someone on trail, it's like hams' "SpotMe" without paying any fee. Fantastic!

This morning was a clear and sunny day here in JN53, but definitely too windy to be comfortable both for me and my telescopic whip antennas. Well, at least all stuff is ready for use, batteries are charged, a good location for portable operation has been identified in the hills behind Livorno, so now it is only matter of waiting for good weather conditions, hopefully in the coming week.

Hi all,

unless blocked by higher priorities, I will perform my very first tx tests next Sunday in the morning from JN53 (portable operation).

Current plan is to use first a ground plane antenna (approx. 7.30-8.30 UTC) then a rotatable dipole (approx. 8.30-9.30 UTC for the N-S direction, 9.30-10.30 UTC for the E-W direction).

The G0UPL Ultimate2 beacon kit will be used for transmission, continuously running following sequence of modes/frequencies, with callsign IZ5WWB:

WSPR 28126,850 kHz
QRSS (FSKCW) 28000,850 kHz
CW 28280,800 kHz

After days and days of a sad propagation 160m comes alive. And how! there were exactly 760 DX spots between NA and EU from 09:24z(11/28) to 08:22z(11/29). The last similar event dated of October 13 with 350 dx spots "across the pond". DX Stations were: WB5WPA, K9PAW, K9YWO, K9AN, W3PM, N2NOM, VA3MW, KC2STA, G8DYK, G8HUH, G3ZJG, G8JNJ/A, PA0O, PA0HCK, ON7KB, PA3MET, PE1MPX, PI4THT, OZ7IT, DK6UG , F59706.

OK, just two days of experience with WSPR.

1. On 20 meters with 1 watt and a Miracle Whip INDOORS, pretty cool what can be accomplished.
2. On 30 meters with an outside end-fed half wave wire at 20 feet high horizontal, 0.5 watts, very impressive.
3. Not much results on 20 after sunset.
4. 30 is ALWAYS open to somewhere.
5. The database queries are cool.
6. Is there any analysis being performed on the data, like what was done with PropNETPSK several years ago?

I have been using a Magnetic Loop Antenna from Alpha Antennas and I'm very impressed with the performance of it. I have this inside my shack and it has done almost as well as my full wave 160 meter loop at 40'. Check out my spots for the past week 11/27 on 20 meters.

Just want to advise our 160m operators that I currently have up a 160m Beverage antenna and a 1/2 wave Inverted V dipole.

As the Beverage is an RX only antenna, what I am doing is running the Inv V for the USA guys (TX/RX) until I head to bed, then switching over to the Beverage to run RX mode till sunrise.

du nouveau ici
j'ai un KX3, vraiment un super tx et biensur en QRP

je vais le servir en wspr sur 160 m
soit avec 5w ou 2 w

via un signalink usb et le cable pour le KX3

le tx chauffe vite a 60 c hi

merci pour tout rx de votre part

noel arrive bonne fête

I have been running 1mW on 40m WSPR for the last couple of days and getting spots from over 2000km away. Such has been the success I have decided to go lower in power and will be going down another 10dB to 0.1mW. From the reports so far at the 1mW level I think I can go much lower still, but I'll try it in stages.

Well, I just got my Raspberry Pi to listen to WSPR stations for me.
Wahoo! Now I get my laptop back for other things.

I like to get a statistical feeling about conditions on 80m.

What i need is a receiving and a transmitting station which are not changing.
It will work all day for about 8 weeks.
After that i make graphs of the signalstrengths over that time.

This Saturday, November 16 Australian radio amateurs will launch a HF high altitude balloon, PSB-5, transmitting WSPR, JT65, THOR and Slow Scan Digital Video (SSDV).

I'm currently transmitting on 20m, 15m and 10m using 1mW.

So far, my best spot is 1,065km, equivalent to >1,000,000 km/Watt ! (Thanks to SWL Dan I1-12387)

My Ultimate 2 QRSS transmitter ( continues to work great. I just received and assembled filter modules for the 40 meter and 20 meter bands, in addition to the 30 meter filter I already had. I'm picking up lots of WSPR reception reports on both bands. I also updated the firmware to the latest 2.06b version (using my Bus Pirate to program the PIC chip in-circuit). The new firmware allows transmitting on up to 3 different frequencies and modes.
