Recently got my General and would like to try my hand at PSK31 in the HF realm. I've got a couple of laptops I can use for the radio in my truck (in my driveway of course!)...besides the cabling...what else do I need? Is a TNC required for PSK31 or is that a software mode for digital?

Thanx.

hi ruxton,

a tnc is not needed for psk31 or sstv modes,
most use an interface to isolate the pc from the radio
or cable the audio to the radio directly.

I like the signalink from tigertronics,
the new usb model has soundcard builtin

psk31 no cost s/w

take a look at sstv software too
no need for expensive hardware as in the past

By the way, rear panel data jack on an FT-857D and a PS-2 mouse or keyboard connector are the same connector ... if you have an old mouse or keyboard lying around you've got the hardest part of a homebrew interface done.

As far as using a keyboard or mouse cable, they commonly have only 4 conductors, and one of them is in the wrong position to be used for an interface or TNC cable to a rig's packet jack. However, a PS/2 extension cable can be used, as they have all 6 wires.

Hello Ruxton;

Let me second what James suggested.  I just got my FT100D (The predacessor to your FT857D) hooked up to my computer via a SignaLink USB from Tigertronics and it works very well.  I screwed around for a year with Rigblaster Plus trying to hook it up via the modular mic jack and never could make it work.  It might've been because of the cruddy soudcard in my ancient HP Pavillion.  The SignaLink has it's own high quality outboard soundcard.  Tigertronics also had the DATA cable for my radio where West Mountain did not.  So the Mic can remain conneceted to the radio while I work PSK.

Anyway in just 20 contacts I've worked Asiatic Russia, Venezuela, Cuba and a bunch of states.  Great mode!  You'll love it

I agree with other posts ... the SignaLink is a great way to go. The new USB interface sounds like a pretty easy way to go. I have the sound card plug-in version (SL-1+), and after getting the pins worked out and connected correctly (3 only used), it works flawlessly. The USB wasn't availabe a couple years ago when I purchased the SL-1+.

Software: I use MixW. If you're going CAT interface (which I don't recommend ... keeping it simple), HRD seems to be the most popular.

Good luck and 73,

Well looks like the signalink is the way to go...Looks like that's good for the next flight check. At 99 bucks...I might even go for one of the APRS/GPS interfaces as well....run that off of my HTX202.

Hi, I have a couple of PSK videos over on youtube. These may answer some questions.
