WSPR - The first GREAT experience as ham

Hi!
Recently i became a real ham with a real licence  IU5HES and i started to tx just for fun with a Raspberry...
I ordered an lpf kit with an embedded 150mW (milliwatt!!!!) and started to tx using WSPR mode...
The antenna used was an home made dipole (tv antenna cable without the shield).

The results are impressive....REACHED more than 8000 km on 20mt band...

JT65-HF-HQ9HQX Log to eQSL.cc ADIF (ideal for SWL's)

Hi there!
Today I show you my last sw for SWL's.

You start logging using JT65-HF-HQ9HQX then my sw convert the log to and ADIF file suitable for eQSL.cc , trying to guess the country too (more than 90% success on country guess)


First of all you must edit the provided "config.ini" file and change the standard message (if you want, it's not mandatory). You can also change the standard message on the fly in the app but you'll loose the changes on the next run.

- The button "Clear local DB" should be used only if you've inserted manually some log into eQSL.cc


- Once the app has been configured, you must go to eQSL.cc and export your OUTBOX into an ADIF file (FOR EXAMPLE IZ5035SWL.ADIF). This step can be done only once just if you've not manually logged any other entry into eQSL.cc from the last time you've used this app.
Import your OUTBOX using the button "Import ADIF outbox contacts into DB to avoid duplicates). It'll take some time if you've a large outbox.

- I suggest NOT to "check" the 2 checkbox on the right pane..they're quite self explanatory...

- You can now import your JT65-HF-HB9HQX by clicking on the button "Import CSV log and generate..."

- You will be prompted to save the new adif file to upload, just save it with a simple name on your desktop (for example "upload.adif")

- You can see on the third column if a new country has been "worked".

- Now go to eQSL.cc and upload the just generated adif file from your OUTBOX section.


- It's easy, don't worry...

I've logged more than 2800 contacts in JT65 at the moment...



If you're interested, the licence costs only 10€, let me know.

REALTIME Elad FDM-S2 usage under Raspberry 3 - LIVE DECODING ON THE SAME RASPBERRY 3!!

Quick and dirty experiments....
Setup:

1) Raspberry 3 running Mate Desktop
2) Elad FDM-S2 connected DIRECTLY to the Raspberry 3
3) Gqrx running on the Raspberry 3
4) Elad_sdr running on the Raspberry (sourcecode available soon, wanna wait the utility will be 100% error free!!!)

The raspberry takes i/q data from the fdm-s2 (with elad_sdr) and put the data to a fifo (/tmp/fifo), then gqrx manages that data and decode :)

Quick and dirty videos...
In the videos i'm connected with my pc using vnc to the raspberry (on one monitor) and on another monitor you can see the real connection to the raspberry (it's the monitor on the right side).

Hope one day someone will donate something for my blog  and my researches :) :) :) :) :)

Fdm-s2 interfaced with Raspberry 3

First test... quick and dirty....hurry up!!!!
 
Raspberry PI 3 recording i/q DIRECTLY from elad fdm-s2 to a file, then the file is played on Sdrsharp under Windows (works in gqrx under Linux too.






MORE TO COME VERY SOON!!! STAY TUNED!!!!!!!

FDM-SW2 Orbitron DDE Driver - One new utility by me!


Hi!

Today I wanna show you my new utility...

A DDE driver for Orbitron to drive the FDM-SW2 software by ELAD.





What you need? ....quite easy...

- FDM-SW2 software
- Orbitron
- My utility

First of all make sure you've enabled the TCP remote control in FDM-SW2:



Now, unpack my utility, for example in C:\Orbitron-FDM-SW2
You'll find 2 files, the app and the config.ini, edit the config.ini and change the host ip to match your local ethernet IP (my PC's IP is 192.168.2.2).

Now edit the Setup.cfg of Orbitron (it's located in the Config subfolder of the install dir of Orbitron).
Add the following line to the [Drivers] section:

EladDDEOrbitron=C:\Orbitron-FDM-SW2\OrbitronFDMSW2.exe

The file should look like this image:



Run FDM-SW2 and Orbitron...

In Orbitron select the satellite you wanna track and go to the "Rotor/Radio" section.


 
In the Driver combobox choose "EladDDEOrbitron" and click on the button on the right....

TADAAAAAAA !!!!!! My utility will run and will keep the FDM-SW2 frequency updated with Orbitron.

You can see my utility in action....




You can download the utility here:
