Problem with gmfsk

[w2bvh]

Hi

After lots of hard work I've got Fedora 3 downloaded and running. I've
also got gmfsk downloaded and sort of running. It receives fine, but I
have some trouble with transmit.

When either tty device (ttys0, ttys1) is selected to control the ptt, I
get a message box that says permission is denied for the device. Does
anyone know how to get permission for these tty's in a user (as opposed
to root) logon?

Also, gmfsk is sort of 1 generation older than the current Digipan and
Hamscope offerings for Windows (to say nothing of MixW). Is there a more
up to date psk31 / mfsk program available for Linux ?

Thanks in advance for any help.

73,
Lenny W2BVH

Hi Lenny.

To fix the ttyS0/1 thing you need to su to the root user and issue this
command.

*chmod 777 ttyS0*

This changes the device's permissions and allows unprivileged users or
their programs to access the device, serial ports in this case.

As for Gmfsk itself, it is pretty crude compared to MixW and some others
but it's the best Linux has to offer for PSK31/MFSK. Believe me, I've
been down that road, at least Gmfsk works.

Good luck,

Kevin, ACØH

After su-ing to the root user - you need to change directories to /dev
and then chmod 666 NOT 777 - 777 would give the "nodes" in the dev directory
<execute> permission which does not make sense for a device node.

To summarize....

su to root
cd  /dev
chmod 666 ttyS0*

Hope this helps

Hi,

Thanks to everyone for the advice on getting permissions for ttyS0/1. It
woked out great and I got my first Linux QSO about 5 minutes later. A
coast to coast QSO with  N6CRR on 15 meters.

Even with advice to the contrary, I'm going to try the K desktop PSK
app, just to see what it does (and if it works). Linux is at least
partly about fooling around with computers, and fooling with another app
is apropos.

Thanks again to everyone for the help.

73,
Lenny W2BVH

Kind of a good fit for the Elecraft, which is about fooling around with
radios... I built my own radio, I compiled my own kernel...

There seem to be a number of Linux users on this list. What are people
using for a logging program? I have XLog and KLog running, but they are
both rather lacking in features. I'm currently using Logger32 (running
in Linux with Win4Lin), but I'd rather have a Linux program.

I'm thinking of writing my own, but it would be a slow process as it
would be competing for a limited amount of free time.

Hi Brian.

On the Linux side I use jLog. It's a platform independent general logger
that runs on Win, Lin, or Mac OS. As long as you've got a Java runtime
installed you can run it on anything. There are several others that look
and run well. You might take a look at gLog as well.

Here's a link to the one good Ham Radio Linux software database on the web.

http://radio.linux.org.au/

Thanks to the others who caught my chmod mistake. Note to self, get
sleep before dispensing Linux advice on a mail list.

Good Luck.

Kevin, ACØH

There is a new version of klog (just out) with more features, although I
haven't tried it yet.

I'm using tlf, which is mainly oriented toward contests.  It's not fancy
(ncurses), but I consider that a feature (it interfaces with hamlib
to communicate with radios).  PA0R, the author, is a K2 user.

Hi Brian

I only use Linux for my logging as I do not have Windows on my computers.

For logging I wrote a small Tk/Tcl program which uses MySQL for storing
the logbook. The program runs under X, I use KDE.

I also have a serial connectin to my K2, so the program
can read/control the Freq, Mode, etc of the K2,
for more information and screenshoots,

see: http://www.raunvis.hi.is/~matti/TF3MA/MALog.php

the program is GPL'ed and is free to download for everyone.

And I you know TCL/TK it is easy to modify the program to suit you needs.

I'm running XLog, but as a Dx4Win user and fan, I'm trying to make it
work under Wine or QEmu. Still unsucessfull...
