A very simple receiver for 136kHz
This project is a very simple receiver for the 136kHz band, with an 12kHz IF. The IF can be fed into a sound card and further processed in software (for example in Spectrum Lab) to get a waterfall spectrum plot, receive CW by ear etc.

Grabber QRSS600 8270Hz
First KLUBNL.PL VLF grabber
We’ve activated the first KLUBNL.PL VLF grabber. Currently it’s avaliable at:
https://klubnl.pl/grabber/grabber1.php
This is an experiment using an old Neoware terminal with a 200MHz CPU, and using the cellular network for the internet link. If this is succesful in the long run we hope to have more of these grabbers online.
We’ve Started!
We’re starting the klubnl.pl webpage.
We’ve been experimenting with unconventional communication methods for a long time. Unfortunately this was usually done in the comfort of our homes, and the results were not shared, which we now see as a mistake. The purpose of this page is to fix this mistake.
We will also be starting a forum soon.
The content will be mostly in polish, but we will try do add something in english from time to time.
