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.

My 24m tuned tower working verry well for dx on top band

Hi: This probably as nothing directly to do with WSPR, but has anyone nothing their PC clock, and hence decodes, change after playing videos? I just watched maybe 10 short videos, and my clock drifted 5+ seconds! That's within a few hours..

QRP Labs new 5W HF PA kit has been released, price $20, see . This is suitable for use with the QRP Labs Ultimate3S WSPR transmitter see and this is described in App Note AN004 see .



2017 News:
The new Worldwide 60 meter band 5351.5 kHz to 5366.5 kHz, goes into effect after 1 January 2017. (not USA)

During the night I switched from a random longwire NE-SW, to a 95cm Magloop, or MLA.
It looks a bit sad drooping down around the support pole, so I must fix that.
And it is placed inside the shack at the moment with axis NNW-SSE. From 0030z to 0900z it was tuned to 30m, and from 0901z has been tuned for 40m. I mistakenly left the TXing for 40m off until just now.
At the first estimate signals, and noise, are a bit lower.

TNX for the confirmations to my previous query.

Finally running again here:
Raspberry Pi 2 with Raspbian and QRPi shield by HA7DCD
Wsprrypi by PE1NNZ
20dBm on 20m
After fiddling around trying to run wspr as a service the excellent page from ÖVSV helped me a lot.

Im getting out but not as far as I want. Will see what the day brings

Is this what shows on the front page?

just bought a Lenovo Ideapad 100, it works ok but had issues finding the right setting for the external microphone connection with the combo jack(4 rings) to have on the same connector HP & Mic.

You must persist to find the right settings if not you have noise of the room injected via the internal Mic of the Lenovo and impossible to set the right levels...

Just to say that at first you can think that the combo jack is not working at all.

Surely computers with standard HP & Mic(external) connections are easier to setup.

TODAY 31.12.16 at 10.00 UTC the Ballon STELLA4 gets in the Air.
Trying to break WSPR highest altitude record.
It is an 800g Latex ballon flying with helium.
The probe transmitts on 30m WSPR, 40m WSPR, 30m JT-9 and 2m CW.
An frequency list is in the pictures.
The transmitter is an modified ULTIMATE U3s.
Livetracking and Infos from my last STELLA missions on Hans Summers pages:
Would be nice to get some Reports!
