Depends on the CPU horsepower and the availability of a sound-card
interface, I think.
With the equivalent of a 200 MHz Pentium (in terms of effective
CPU cycles) and a 16-bit sound card interface, it's pretty easy
to use the sound card and CPU as a pseudo-DSP to do PSK31, AX.25
packet at 1200 baud (with TCP/IP on top, if you wish), RTTY,
and probably most of the other low-to-medium-speed digital modes.
Add a GPS receiver of some sort and you can easily do APRS.
Controlling the radio is also a real possibility, using e.g.
hamlib and its various front-end packages.

Hi!
Which type is your handheld computer?
I want to buy in future a good handheld, but I dont know, which give me
good audio input. Because all handheld are good audio output (see mp3
listening is popular), but the A/D is oft not so good.
I want try HAM digital modes with Yaesu FT-817 from hill, and it is good,
if this "pack" is lighter as 2 kg. :)
A notebook is 2-4 kg, the FT817 is 1 kg.
Important for me:
- OS: Linux (or POSIX compatible - it's important)
- I need development packages (for example: cross compiler, which I can
run in my normal PC, and I can here compile program for handheld.
- The sound interface must good (not only D/A, also I want good A/D).
Can you some typ advise?
Thanks,
Zsolt, hg2ecz
I reply:
Hamlib: didn't get too far on the desktop with my Kenwood TH-F7E.
Maybe if I just limit my goals to
> Merely check frequency tables
then I can get the cheapest monochrome handheld and use the
$ apt-cache search palm
stuff to download the tables.
