SM6VNO's quest

 SM6VNO Ander's quest is to be able to detect PSK63 APRS transmissions on HF by programming software himself. You would probabely think this is a little outdated, software like pinpoint and APRS messenger already feature kind of the same thing. However it is the experiment that Anders is interested in. He asked for my help to transmit a test signal already in May this year. Unfortunately my signal was not received. Now Anders has upgraded his magnetic receive loop with some chokes in at the coax which helped a lot to improve receive. He asked to transmit a signal again and was finally able to receive me and forward kind of a location to APRS-FI.


As received/decoded by Anders his experimental software.


As plotted in the APRS map. Although the location is wrong, but not really important. The main experiment for now was to receive/decode my signal.

The art of...

 The art of communication...


I had a great chat on 20m VarAC with EI7II Albert. Surprisingly in my native language which was of course a pleasure. Albert is living in southern Ireland and works 7 days a week for free to save animals at a sanctuary. It was niced talking to him. Actually I had to do several CQs before someone responded. Many give up on VarAC as it looks like it is only a beacon mode, but it isn't. I often think about the possebilities of this digicom software. I think there should be something else as chatting alone. Yes, there is a kind of e-mail possebility, that's nice. But after I send so many "V-mails" and get not anything in return it is kind of boring. It might be an idea to introduce some simple games you can play. Like chess or battleship. I remember playing battleship 25 years ago on packetradio, so....why not.

The art of electricity...

The wiring in our house is about 50-60 years old. The previous owner was not really an gifted electrician I think. I've replaced several junction boxes over the years with most of the time crappy twist-on connections between the wires. I'm now in the process of rebuilding part second floor and wiring is actually on the future third floor. I knew I had to replace another junction box and this evening it was the time for it because the other members of the family were out the house.

The old junction box was broken. All cables are old stiff thick cables with old color coded wires. When did they change the colors here in the Netherlands? Somewere in the seventies of last century. Imagine thats 50 years ago. The previous owner even managed to use 4mm wire to the garage from this junctionbox. Oh my, these days 2,5mm is normal. These thick wires do not fit in most used wire connectors. 


But all is solved. I think I am a magician ;-)
