MFJ-1278B MULTI-MODE BASIC OPERATION

Receiving SSTV Pictures

Note that if you are using one of the special terminal programs that supports color or multi- gray levels SSTV operation, you should follow the instructions given in its operating instruction manual to receive and transmit SSTV.

The SSTV operation procedure given in this instruction applies to the receiving of 4-level SSTV pictures with a EPSON graphic printer attacted to the MFJ-1278B printer port.

From command mode, the MFJ-1278B can be set to SSTV mode by typing:

MODE TV <ENTER>

Select the desired SSTV formats by using the TVMODE command. To select the desired TVMODE type the following from the cmd: prompt:

TVMODE n <ENTER>

where n is the TV format 1 through 5 as listed in SSTV Format Table 4-9. For example for 8.5 Second TV format, you will type: TVMODE 1.

The default SSTV mode for MFJ-1278B is TVMODE 1 (8.5 seconds format).

After tuning to the desired SSTV frequency, observe the TUNING INDICATOR of the MFJ-1278B while fine tuning the radio. You will notice that with each scan the tuning indicator will move toward the center. Tune the radio so that the 10th LED segment from left is lit at the end of each SSTV line scan. Once you achieve this, the SSTV signal is tuned in. The DCD LED should light. If DCD LED on the MFJ-1278B is not lit, rotate the THRESHOLD control until it is lit.

SSTV Printing to the Printer

At this point you will want to ensure that your printer is properly set. Make sure that your printer to set to "EPSON GRAPHICS" or "IBM GRAPHICS" mode. This is usually selected by DIP switches on the printer. "IBM GRAPHICS" mode is not the same as "EPSON GRAPHICS" mode. If you are using an EPSON graphics printer, you should turn the IBM GRAPHICS mode off and set your printer to EPSON GRAPHICS mode.

Although most commands of the MFJ-1278B that affect SSTV printing are defaulted to allow successful printing, you should check these commands before printing any SSTV picture. You should insure that the commands EPSON and PRINTGRA are ON. The default values of these commands are ON. SSTV printing to the printer will not function unless these commands are turned on.

Note that PRINTGRA should be turned ON only if you are printing pictures through the
