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
Also there is a CW-special mode for e.g season greetings.
Later this year there will some more modes to be added.
The beacon produces 5w input into a 4-band inverted-V.
On request I can change power/mode/time for experiments.
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:
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:
