A paper QSL-card will be send after confirming your contact by email.

And feel free to mail me screen-shots/audio recordings when I'm doing

digital modes. Specially screenshots from my PI4 beacon..


For transmitting a better signal of the 4m beacon, I'm looking

for an HALO-antenna. It can then higher placed and my tropo

distance will extend. Sponsoring of material (or compleet) is

welcome. Have Paypal, a donation is also welcome.


I'm also looking for a Linux freak for helping me to

make the beacon webbased & interactive.


On 70.095.000 having a PI4 beacon like the OZ2M style

Dial is 70.094.200 USB for use with the PI4-rx programm

It is time scheduled from UTC 7.00 till UTC 21.00.


The sequence is:

00 - 24 seconds PI4

25 - 35 seconds CW FSK

35 - 59 seconds carrier


The beacon produces 5w input into a 4-band inverted-V


PI4 is designed to serve most kind of (known) propagation.

Like tropo, Es, Au, meteor scatter and airplane scatter.

When you hear the beacon, I prefer to notice it in the DX-cluster.

The beacon is already heard by 11 DXCC:

9A, CT, DL, EA, IK, IS, OE, OH, PA, S52, SV



For more info/software use these links:




Everything is homebrew with the Arduino 2560, DDS 9850

and the OZ2M 10/4 transverter with PA.

When you self want to run a PI4-beacon or normal CW, this can

very cheap. For aprox. 20,- euro you have a nice ready kit.

(price is exclude GPS-unit from Ebay or so). Take a watch at:




But when you like, you can change the Ultimate

software into my written PI4-programm.



PI4 software for the Arduino 2560 is written in Arduino's C++

A PI4-version in C++ for the Ultimate 3 is availble.

And I have a CW-keyer for the Ultimate 3.

Also an setup for all ports of the Ultimate 3

for programming your own software.


C++ software and pictures are availble with this link:
