630m pirate?

Tonight I’ve decided to try QRSS on MF and while I was transmitting I’ve seen on DK7FC grabbers a strange signal between mine and IK1HGI’s. The call was C7MW which prefix is allocated to the World Meteorological Organization. With Stefan’s RDF spectrogram is possible to see on the next picture that signal comes from E/W direction.

Any […]

QRSS10 & WSPR dual transmission last night.

Due the lack of public MF grabbers on the net, last night I’ve tried to receive my signal in qrss10 with remote WebSDR system. I alternated the two transmission mode so to have an idea about where my signals were received.

With great surprise receiving myself on Twente WebSDR my signal was audible and even […]

3rd August solar storm MF observation

For the expected solar storm of last 3rd August, I’ve planned a continuous 72 hours transmission of my MF station as QRSS10 beacon since 1st of August afternoon. I’ve monitored my signal on the MF grabber of Stefan DL7FC, comparing it with IQ2MI signal, downloading for the 72 hours a picture any 10 […]

Ultimate 3S by QRP Labs is here!

Just arrived (10 days from Japan) I’ve worked for a couple of hours to assemble the U3S Deluxe kit from QRP Labs, later I wanted to try the GPS receiver for my LF activity by Spectrum Lab, so I made the smoke test giving 5 volts to the GPS receiver.

After a while all LEDs […]

472khz.org

Rik ON7YD created a new web site concerning 630 meter band, http://www.472khz.org/.

I invite you to take a look to this interesting source of informations for all whom are looking for “how and why” about this band.

30 meters MEPT again On the Air!

Last night I powered my old 30 meter DFCW QRSS3 MEPT.

It is strange to see how 400mW can reach Tasmania:

IK0VVE@VK7ZL (Tasmania)

IK0VVE@G0MQW

IK0VVE@LA5GOA

IK0VVE@NL9222

IK0VVE@PA1GSJ

IK0VVE@PA2OHH

IK0VVE@PA3FYM

Some grabbers from USA have a weak trace of my signal but it’s not readable, this mean that my […]

Grabber Aggregator page problem solved

I’ve had some problem on Grabber Aggregator page on December, it seems a server error; I’ve only reloaded the original .ASPX file on server and again the page was online.

Thanks Colin!

Happy 2009 to everyone!!!

Grabber aggregator page 120.000 visualizations!

Grabber Aggregator page has been visualized 120000 times in 14 months!!

Here is the analysis screen shoot.

On 24th of August 2008 a peak of 1901 visualizations.Thanks to all grabber manteiners!

Laurence, 9V1LF, advised me that He’s in Alaska now as KL1X; time and call has been updated on the aggregator.

Any suggestion is welcome.
