MFJ-1278B MULTI-MODE                                          INTRODUCTION 
INTRODUCTION 
Welcome to the exciting world of Amateur Digital Communications.  By choosing the MFJ-
1278B, you have chosen the most versatile and powerful Multi-mode Data Controller 
manufactured for the Amateur Radio Service. 
 
The MFJ-1278B interfaces your radio with any personal computer that has an RS-232 or 
TTL level Serial Port and a terminal program.  While most communications programs will 
work, MFJ recommends the use of MFJ Starter Pack for those who have IBM or compatible, 
Macintosh, Amiga or Commodore C64/128 computers.  With an IBM or compatible 
computer, the MFJ Multicom terminal program gives you some added features that a standard 
terminal program just can not offer.  Features such as color SSTV, color FAX, 16 gray level 
FAX, and color VGA packet picture transfer, just to mention a few.  Multicom is menu 
driven, making it easy to operate all modes offered by the MFJ-1278B.  Dedicated functions 
keys are programmed to operate most functions with a single key stroke. 
 
Even though the MFJ Multicom programs offered for other computers may have features 
different from the IBM version, they do offer features that will make operating the MFJ-
1278B very fun and very easy. 
 
This compact versatile controller employs the genuine TAPR TNC 2 AX.25 protocol packet 
firmware plus many added features to receive and transmit VHF packet, HF packet, AMTOR, 
CW, ASCII, RTTY, color FAX, and color SSTV.  The new 16 gray level fax board built in 
the MFJ-1278B gives you the ability to receive and transmit color SSTV and multi-gray level 
FAX pictures.  In addition, MFJ-1278B lets you monitor the new and growing NAVTEX 
broadcasting system.  The MFJ-1278B also has a Contest Memory Keyer mode. 
 
Also a feature which so many have asked about, Pactor has been added to the operating 
modes.  The new Pactor mode gives the user operating features such as  Digital Memory 
ARQ
, full  On-Line Data Compression,  FEC Unproto operation, just to mention a few.  
Also included with the PACTOR mode is a PACTOR Mailbox.  With the Pactor mode also 
comes the ability to monitor AMTOR ARQ connect requests. 
 
The MFJ-1278B offers the most versatile mailbox available when compared to the mailbox in 
other controllers.  This mailbox allows a dedicated mailbox callsign so that the mailbox stays 
on while you operate packet.  Other features like auto forwarding or reverse forwarding of 
mail to and from other BBS systems, remote sysop access, sysop paging, mailbox ctext, chat 
mode and a "has mail" LED indicator.  The MFJ-1278B has 32K mailbox memory which is 
user expandable to 128K or 512K by simply replacing the mailbox memory IC  -- a feature 
that no other controller offers. 
 
You also get MFJ's 20-segment, 10 Hz Precision Tuning Indicator that makes tuning simple
