#js8call

0 posts0 participants0 posts today

Playing around with FreeDATA (freedata.app/) app on 40 meters. What a nice modern application, can operate keyboard-to-keyboard QSO's and leave messages from a remote PC using a webbrowser. Seems like a nice modern alternative to #JS8CALL. It's based on the open source #Codec2 which is also used for #FreeDV and #M17. No need for proprietary software modems like #VARA anymore. If you like stuff like #VarAC or #JS8 give this a try! #hamradio #ham #freedata

Today, my first #js8call QSO ever!
jpc12 antenna, 20 radials, self-built QDX transceiver, 20m band.

Chatting (quite chaotic*) with Tim USA at 6600 Km. Exchanging heartbeats with Australia.

Amazing to be able to chat with the whole world with a 5W #qdx transceiver as big as a cigarette pack plugged into my PC via USB.

* now I have to learn how to properly conduct a js8call qso ;)

@EA7KRC #ft8 is an interesting mode as it has a negative signal to noise ratio. As such, it allows to make connection, where other modes can not. My critique is, that it is tailored to just confirm the exchange. Built on the same modulation, #js8call is more liberal and allows to have longer conversations as well.

The beauty of #hamradio: there is something in it for any interest.

@rhett #aprs for short messages and information retrieval (not so much into positioning). #packetradio or #ARDOP for #winlink emails (no windows, no #vara). #js8call for some asynchronous message and data exchange (not much experience yet). #M17project looks interesting. It is #foss enabling us to execute our #hamradio right to experiment (not like all that closed proprietary stuff: #DMRradio, #c4fm / #ysf and #dstar).
