QSL: PAPER QSL WILL SEND AFTER CONFIRMING BY EMAIL

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 welcome.

 

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

make the beacon webbased & interactive.

 

On 70.095.000 having a multimode beacon with JT6M & PI4.

For both mode the dial is 70.094.200 USB when using the PI4-rx

or WSJT programm. When right tuned the CW carrier is at 800Hz.

Therefor the announce frequency in the cluster is 70.095 !!!

The PI4 mode is time scheduled from 9.00 UTC till  21.00 UTC

The JT6M mode is also time scheduled with the major big showers

and is scheduled from 18.00 UTC till 9.00 UTC.

 

The major showers are:   1/1 -    9/1      Bootiden

                                         1/7 -  13/7     Arietiden

                                         7/8 -  19/8     Perseiden

                                       8/12 - 20/12    Geminiden
 

The JT6M sequence is:     02 - 28 seconds JT6M callsign

                                          32 - 50 seconds CW FSK callsign/locator

                                          50 - 59 seconds CW carrier

 

    The PI4 sequence is:     00 - 24 seconds PI4 callsign

                                           25 - 42 seconds CW FSK callsign/locator

                                           43 - 59 seconds CW carrier

 

The beacon produces 8w 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 13 DXCC:

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

 

 

For more info/software use these links:

http://rudius.net/oz2m/ngnb/index.htm

 

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:

http://www.hanssummers.com/ultimate3.html

 

 

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:
