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.

Rambling thoughts....

Been out of the Ham Radio loop for many years and just beginning to get myself back in. Have been working on servicing my old kit (HW101 and Icom IC202) to get them up and running again. So far so good. Only problem is the VFO drift is way too high - so am looking at adding a stabaliser to the HW101 at least. First job is to build a simple frequency counter (thanks to EI9GQ).

So the only activity at the moment is a Raspberry Pi with homebrew amp and LPF running as a beacon on 40m. Antenna is the proverbial bit of wet string, so not that impressive so far. With the VFO drift issues on the rigs - reception is not feasible on WSPR, so sorry, no reports.

But onwards and upwards ....


2m WSPR in JA

Tonight, I've worked 2m WSPR with JA1KWV in Tokyo.

160m on Wellbrook 1530 loop and Anan100D SDR

Tonight I will be monitoring 160m with a Wellbrook magnetic RX loop fed into my Anan100D. Hope for good spots.

WSPRNET downtime early Saturday

I plan to try to move the WSPRnet server to a hosting provider early Saturday UTC, probably 0200-0400Z. Downtime should last about an hour, but I'm not sure of the timing yet. Thanks for your patience and understanding!

big measurement experiment is now started.

15 januari 2014
To day i started my big measuring program to get a statistical
feeling about conditions on 80 m. over 240 Km. distance.
A 10 Watt transmitter is running now with a 40m. endfed longwire at
about 6 meter above ground (West-East orientation)
This rig will operate for a few weeks without any changes.
My receiving station is located in Breda with call: PA0JEN
This station also will not change.
PA0JEN has a high level of local noise in an urban location.

10mW on 30m with an attic dipole from Sussex, England

Just thought I'd write up a quick note about my station. I built it up over christmas, it was a great excuse to get the iron out and remind myself how to solder again.

I'm running a Raspberry Pi with JamesP6000's fork of the WsprryPi project, which is a credit to all concerned. James has added some useful options to the software which makes keeping it on a stable frequency quite simple.

This is connected up to a low pass filter for 30m and finally a simple 1:1 balun which I built following ea4eoz's writeup.

This is all contained in an old cigar box(!), which is then connected to a dipole cut for the 30m WSPR frequency. The dipole is just cheap speaker wire and this is strung up in my attic.

It's been running for about a week so far, with my distance record being just over 1000km so far - not bad for 10mW and a less than ideal antenna arrangement.

I'm currently only running on 30m but when time allows I will probably add another filter and antenna to the setup and see how I get on.

I was first licensed twenty years ago (and previous to that was an SWL for a number of years) and have had some time away from the hobby, so this is my first time back on the air for well over a decade.

The whole field of weak signal propagation is fascinating and this project has sparked my enthusiasm for data modes so I am gradually building my shack up and will explore further some of the technologies which have emerged over the past few years, such as psk31 and weak signal modes. I might even dip my toes into QRSS.

17 Meters - RX/TX - 1W

I have the Flex set up to beacon WSPR on 17 meters. Output power is 1 watt. The antenna for transmit is the 30 meter delta loop. For RX, both the 30 and 40 meter delta loops are used in diversity to the two receivers on the Flex.

ULTIMATE 2 Beacon QRSS on 20 meters band active in the coordinates JN72CK Italy IK6ZEW !

On the frequency of the 20 meters 14.097.08 and 'active 24 hours on 24, my beacon in qrsss way. The antenna is a dipole positioned east / west, and the power 'of about 20 db. More info and updates visit QRZ.COM IK6ZEW looking for.

My blog.

Testing lower power

I usually use WSPR with 5W out, but tonight I plan to leave it on with just 500mW or so, to see hot it turns out. 7MHz band, 41m long OCFD.

Back on after long Layoff

Finally back on using Elecraft K3 (5w) into a loaded whip antenna at 13m (for 160m).

How does a bad spot get removed?

Hi there is a spot that has its year set to be 2030 that always sits at the top of the 50MHz band listings, does anyone know how to get it purged?

40 mtr vertical

My latest aerial has been a vertical for 40 mtrs .
This 33 ft long with 30 radials laid on the ground not buried and a 5 ft copper ground rod. The vertical is mounted 2 feet off the ground.
Performance on WSPR has been very good with reports from VK & N2 4X and ZR.
No loading or tuning required and the SWR is 1.7.1 and the resistance is 37 ohms so it looks about right.


Tell N9WKW he's reporting on the wrong band!

CAT Control For Kenwood TS-590S

I use a Kenwood TS-590S and don't see it in the WSPR v2.0 r1714 software CAT menu. Does anyone know if the Kenwood TS-2000? CAT selection will work?

Request to Santa Claus

My daughters tell me that I was very nice throughout the year. So my request to Santa Claus is simple, I want to spot Leigh (VK2KRR) in 160m soon ... HI!!! I do not know but this season it does not happen ...
Merry Christmas to all,
