What do I need to run JVComm32?

What do I need to run JVComm32?

A receiver or transceiver:

• If you require HF-FAX weather charts you will need a good quality shortwave SSB receiver

  If you want to receive low earth orbiters you will need 137 MHz receiving equipment

  If you want to receive geostationary satellites (SDUS transmissions only) you will need 1.7 GHz receiving equipment

• If you want to receive and transmit SSTV you will need an appropriate HAM band transceiver

A computer:

• running Windows 95 up to Windows 7 (RC) at least 128 MB of RAM, better 256 having a state-of-the-art processor at 166 MHz as a minimum having a high- or true colour graphics with at least 800x576 resolution
• a standard 16 bit sound card or better, or a serial port to connect to an external interface

A connection between your receiver and your soundcard’s line-in:

• preferably a mono cable with 3.5mm plugs,  see installed documentation for alternatives

If your computer is not equipped with a sound card, you need an exteral interface:

Here, interface means a kind of modulator/demodulator that connects your computer to your receiver/transmitter. It transforms the audio data from the receiver into digital data that the computer can read. On the other hand, the interface transforms the digital data that the computer delivers into an audio signal that can be fed to your transmitter. JVComm32 runs with standard 16 bit sound cards and the PTC-II DSP multimode PACTOR-Controller by SCS and its successors.
JVComm32 does also run with the Bluetooth version of the PTC-II. When you are using this version, the PTC-II SERBaud parameter must be set to 115200, and the data rate to 11520.There are some more interfaces that you can use for JVComm32, e.g. the EasyDSP interface by Ulrich Bangert, DF6JB (no longer available) and the HariFax IV interface.

If you want to construct you own interface, you can get technical information on how JVComm32 manages the data transfer from and to the interface.
