MFJ-1278B MULTI-MODE BASIC OPERATION

SSTV Formats

The MFJ-1278B provides a dedicated multi-gray level modem for SSTV operation. The modulator and demodulator frequencies of the MFJ-1278B are pre-set at the factory to allow SSTV operation without any recalibration. The MFJ-1278B supports all SSTV formats listed in Table 4-9.

Table 4-9: MFJ-1278B SSTV Formats

*These formats require using a special terminal program.

The SSTV format can be changed by using the TVMODE (n) command. The n is a number from 1 through 5 as listed in the Table 4-9. For example, to set MFJ-1278B to 12 second SSTV format, you would type:

TVMODE 2 <ENTER>

The MFJ-1278B would be set to receive or transmit SSTV in the 12 seconds format. Other SSTV formats can be invoked by tuning the TVX command ON.

SSTV Installation

Installation of the MFJ-1278B for SSTV operation is the same as for the other modes of operation. Installation of MFJ-1278B to your radio is described in Chapter 3 of this instruction manual. You can use either Radio port for SSTV operation.

Printer Connection

If you have a terminal program which supports SSTV picture printing to the computer screen, then you should attach your printer to your computer printer port and not to the MFJ-1278B. In this case turn the PRINTGRA command OFF. IF you intend to receive the SSTV picture and send it to the printer that is attached to the MFJ-1278B parallel port, then you should turn PRINTGRA command ON.
