Stefan DK7FC has been recently transmitting on 6470Hz (46km wavelength) from a stationary antenna between two buildings.
The Ebnaut transmissions were received by Paul Nicholson (England) and Jacek SQ5BPF (Poland) at a distance of 900km (IN49IK to KO02MD).

USA hams just got the 137kHz and 472kHz bands.
Spring has started, which is bad for LF/MF, but we hope that the first Poland – USA contact will be in 2017.
On 10 march 2017 Stefan DK7FC experimented with transmitting on 2970Hz. The signal was received in Todmorden, England by Paul Nicholson at a distance of about 850km!

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.

Second KLUBNL.PL grabber, this time for 8270Hz QRSS600. QTH KO02md
8270HZ QRSS600 grabber
We’ve activated the first KLUBNL.PL VLF grabber. Currently it’s avaliable at:
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’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.
