You can use a basic terminal program similar to Pacterm The following chart is a list of currently available sound card software programs.Īlthough, I believe, sound card versions will soon replace the 'normal' tnc decoding, there are still many tnc users out there. Sound card versions are really fantastic. I use the Kantronics KAM, although other manufacturers including MFJ make fine TNC's.

It is a very interesting mode, one that once you start you will be a permanent convert. One reason for this is that it requires no handshaking with another station and a multi station round robin QSO can be enjoyed. This is the most popular Digital Mode on HF. There is no SSTV in FLdigi so you will have to look at something like q-sstv but it hates my line input settings and refused to work on any /dev/dsp settings, so it be time for a compiling session in my dreams tonight.Please print this article and use it as a hand out at Club talks and lectures Set the PTT switch to VoX for easy use if you are in QSO mode or use the fixed PTT oprion to TX BUT be careful that you have no local voice coms else you will be booted of Hamsphere for 5 minutes as 10mhz does not take voice just data like I was by an over zealous admin who thought HELL as a digital mode, did not sound right.Īll modes work well, but forget CW in the short term as it seems a tad difficult to get the proper RX decoded in multi QSO's (just like normal) Power settings in most cases should not exceed 6ģ. Mic input setting to about "3" so the audio level does not exceed the normal voice levels (I use the Green settings on the S Meter and set it to peak at the end of the green bar)Ģ.

You need to set the Hamsphere application (I use the Java based one in Linux) to the following ġ. How this is where it gets a bit difficult.

But you will need volume "11" set on the Hamsphere App to RX any signal (the waterfall remain blue in most cases with yellow on RX signals - so lower levels than you may be used to but it does work) It pays to turn the local volume on the headset / speakers down so you do not go deaf on RX/TXģ. Set the sound card (Configure|Sound Card) input up to your "line" device input not your mic inputsĢ. I confirm all modes in Fldigi work 100% with Ubuntu and the Hamsphere Java App at least on my box here in Bangkok, but like most things it is not super easy to set up (or is it - you decide).ġ.
