Linux Kernel

From the Sound HOWTO:

"Another novel use for a sound card under Linux is as a modem for amateur packet radio. The recent 2.1.x kernels include a driver that works with SoundBlaster and Windows Sound System compatible sound cards to implement 1200 bps AFSK and 9600 bps FSK packet protocols. See the Linux AX25 HOWTO for details (I'm a ham myself, by the way -- callsign VE3ICH)."

Erfahrungen / Experience

Allgemein / General

Sound Card:

Many of these programs use a direct access to the sound card hardware, thus so-called "Soundblaster compatible" cards often will not work. So use an original Creative Labs Soundblaster card (Pro, 16, 32 AWE, 64 AWE) whenever possible. That does not mean that your compatible card will not work at all; it depends on the program. Some programs will work with many cards, some only on original SBs. Just try, but keep in mind that you may encounter problems.

Always install the latest driver available, since older drivers might contain bugs. - Some programs (e. g. W95SSTV, ChromaPix) that run under 32 bit operating systems (Windows 95/98, NT) may require a 32 bit sound card driver. Even a driver for Windows 95/98 does not automatically have to be a 32 bit driver - sometimes it is a 16 bit driver and you will not even know.

Do not tune the input and output volumes to its maximum, 1/3 usually is enough, larger volumes can cause distortion since the audio amplifiers on sound cards are not quite linear.


When using the "Microphone" input of the sound card, the signal will be lead through the microphone preamplifier. So do not use the "Microphone" input since this can cause distortion - always apply signal to the "Line In" input. Same is applicable for the output; use "Line Out" instead of the "Speakers" output.

When connecting to the radio, usually a direct connection will work. If you encounter problems with hum or others (noise caused by the computer etc.), try an audio transformer or a capacitor in the signal path to avoid galvanic connection. Consider the impedance of the sound card and your receiver / transmitter.

At the receiver, use a fixed level audio output e. g. for tape recording, if your receiver has such an output. If not, use the audio output but tune it to about 1/3 of maximum volume - more can cause distortion. High speed data (such as 9k6 packet radio) will need the connection to the discriminator output of the FM chip, the normal audio output will not work.


If the program has transmit capability, the radio needs to be switched to transmit mode. Sound cards do not have a PTT (push-to-talk) output, so additional hardware might be neccessary. Many programs use a simple device like the DSR or RTS pin of a serial port to switch the PTT, this signal will switch a transistor which sets the PTT input of your radio to ground level. Please read the programs documentation to see what device will be neccessary. Sometimes (when fast switching is not required) an audio Vox circuit or the Vox of your radio can do the switching.


Verwendete Hardware und sonstige Software:

PC 486DX/33 MHz, 8 MB RAM, Soundkarte Shuttle 48 (SB 16-komp.; sp?ter original SB 32 AWE), MS-DOS 6.22, GP 1.61b; Icom IC-820H


Funktioniert (sowohl 1200 bps als auch 9600 bps)
Man sollte bei der Implementierung schrittweise vorgehen:
1. Schritt: Keine Verwendung der Soundkarte und der daf?r ben?tigten SB-Treiber, sondern Konfiguration f?r ein vorhandenes Modem. In meinem Fall war das ein 1k2-BayCom-Modem (ser.). Das Modul TFEMU ben?tigte die Option /dm, damit es mit GP zusammen lief. GP ist recht gro?, daher EMS notwendig. L?uft mit EMM386 zusammen.
2. Schritt: SB-Treiber, 1200 bps. Es stellte sich heraus, da? die SB-Treiber nicht zusammen mit EMM386 laufen; ohne EMS im konventionellen Speicher war nur noch eine Minimal-Konfiguration von GP m?glich. Eine Umstellung auf QEMM brachte Abhilfe, nun kann GP wieder in normaler Gr??e geladen werden. - Es war notwendig, die Soundkarte als Windows Sound System zu konfigurieren. - Als PTT wurde die L?sung f?r die serielle Schnittstelle gew?hlt (-> COM3: mit gleichem IRQ wie COM1:, dort wird die Maus betrieben, ergab keine Probleme). - Aus bislang ungekl?rten Gr?nden st?rzte das Programm beim Starten manchmal ab; wenn es gestartet war, lief es ohne Probleme. Dieser Effekt wurde sp?ter mit einer Original SB 32 AWE nicht mehr beobachtet. Die SB 32 AWE ist nicht als WSS konfiguriert.
3. Schritt: 9600 bps. (Shuttle 48: Die Aussendungen klappen offenbar, da mein Digi darauf reagiert, der Empfang aber nicht.) Erneuter Test mit SB 32 AWE - funktionierte auf Anhieb. Allerdings wurde auch ein anderer Digi zum Testen verwendet (DB?EA statt wie bislang DB?MSC; letzterer hatte selbst einige Probleme bei Geschwindigkeiten > 1200 bps). Inzwischen funktioniert es aber auch mit DB?MSC.

Fazit: Das Flexnet-Programmpaket kann wirklich jedem empfohlen werden, der schnell und g?nstig in PR 1200 bps oder 9600 bps QRV werden bzw. von 1200 auf 9600 bps "aufsteigen" m?chte. Das Setup ist aber nicht ganz einfach.

Verwendete Hardware und sonstige Software:

PC, Win95; LOWE HF 150


Probiert habe ich bisher nur Funk Fax. Funktioniert ganz ordentlich (auch unter WIN 95). Allerdings sind selbst bei einem schon sehr hohen NF Signal/Rauschabstand von 48 dB die empfangenen Bilder nicht gerade perfekt was allerdings auch an meinem Empfaenger (LOWE HF 150) liegen kann.

Hardware and software used:

Pentium 150, 48 MB RAM, video capture card Winnov Videum AV (with integrated soundcard), Sony Camcorder, Windows NT 4.0 SP3


W95SSTV really is a great piece of software and easy to use. The setup is easy, you should know that the input level (see volume control) should be quite small in order not to distort the sigs (should not excced 1/2 - and it should not be muted...). Includes good documentation. The hardware requirements are quite high (486 and Windows 95 is minimum, better Pentium and (I'd say) NT), but if you meet them, W95SSTV truely is all you need to become QRV in SSTV in the best and cheapest way possible. Try it out! (if this sounds enthusiastic about this program, you got the message... ;-))
