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.

Generally, propagation conditions in 160m wspr between NA and EU are erratic. Similarly, an NA signal can be heard strongly somewhere in Europe and 500km away from there the signal is zero. Well, last night and around EU sunrise, Ian (N9XG) showed us something very different. Its 5w were heard continuously from 03:36z until 07:16z in a wide band from Goteborg (Sweden) to Valencia (Spain) by 10 European stations: The lucky ones are (fm north to South): SM6WZI, OZ7IT, G8DYK, PA0O, PE1MPX, GW0OAJ, G4BOO, DK6UG, F59706, EA5ZL. Congratulations to Ian (N9XG) for this wonderful session.

I checked into the Northern California 432 SSB Net on 432.100 MHz at 1900 PST on Sunday night and also listened carefully as 1 kW net control station KG6HXI in Wilton CA swung her large Yagi antenna calling for check ins around the compass points. I heard some weak SSB signals at or below the noise level from the north and south SF bay area. This suggests that 432 MHz WSPR contacts are possible from Sacramento to those areas.

Hi Folks:
I've been monitoring 15 min mode on 160, but no hits. Is there a distinction in the activity list for 15 min mode? I don't see anything.

Listening only on 30 meters. The antenna is a delta loop whose base is 10 feet off the ground. The loop is fed 1/4 down on one side with window line. The RXer is the Flex 5000A and I am using the second receiver as the source for WSPR.

Ho attivato un trasmettitore a Cerano Italia (JN45ik)

Ora trasmettitori 24h24 UTC con qrss un dipolo a ( V )lungo 7,13 x 2

Open again to VK5 via Ducting through a High Pressure cell. Calling on 50.276 MHz JT65 when WSPR spots a path.

Now trasmitting (until approx 17.00 UTC) with Ultimate2 v2.05 and a very provisional dipole from my balcony in Livorno, Italy (JN53), with orientation towards West.

FSKCW 28000,850

Frame length (cycle repetition rate) is 10 minutes

Callsign is IZ5WWB

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
