from the predecessor model MFJ 1278 The manual of the MFJ 1278B lacks the lower. edge This was supplemented as far as possible with texts from the older manual This. text is marked in blue letters Text passages that could not be reconstructed are marked. with the reference,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 recom. mends 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 Fea. tures 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. 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. 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 PAC. TOR 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 oth. er 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 128 k or. 512 k 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 for HF. This manual has been compiled from the manual downloadable from MFJ and the manual from the predecessor model MFJ 1278 The manual of the MFJ 1278B lacks the lower edge This was supplemented as far as possible with texts from the older manual This text is marked in blue letters Text passages that could not be reconstructed are marked
