MFJ-1278B MULTI-MODE BASIC OPERATION

Memory Repeat and Buffer Repeat Time

Of the ten memory buffers provided by the MFJ-1278B, memory buffer 0 has a repeat function. The user can enable the repeat function, moreover specify a time interval. The BUFTIME specifies the time interval between repeats of memory buffer 0. Values from 0 to 65,535 are suitable for the BUFTIME command. The increments of the BUFTIME are in seconds. A BUFTIME of 0 seconds represents no repeat after sending Buffer 0, thus disabling the repeat of Buffer 0. The BUFTIME command is usable only in the CW, MCW and Memory Keyer modes. The BUFTIME command is not effective for memory buffers 1 thru 9.

BUFTIME is the TOTAL time for one cycle of the Buffer 0 message. This means that if your buffer message is 10 seconds long, then you must set the BUFTIME command longer than ten seconds. So if you need to have a 5 second delay between repeats, then set BUFTIME to 15 If you do not set the BUFTIME command longer than your message, then the message will be repeated maybe before it is finished. This will result in incomplete copy by the receiving station of the Buffer 0 message.

If your buffer 0 message is 10 seconds long, and you want Memory Buffer 0 to repeat every 5 seconds, under CMD: command prompt, type:

BUFTIME 15 <ENTER>

Memory buffer 0 will repeat every 5 seconds. To stop memory buffer 0 from repeating, set

BUFTIME TO 0.

If BUFTIME is a non-zero value, the MFJ-1278B will automatically release the PTT line and revert to the receive mode between repeats. This allows you to monitor the frequency, possibly for a reply message. If uninterrupted during the pre-set delay time, then the MFJ- 1278B will continuously repeat buffer 0, until BUFTIME is set to non-zero value.

Chaining the Memory Buffers

Chaining of the ten memory buffers in order is possible. This enables the transmitting of the buffers in any order. For example, you may transmit memory buffers 0, 2, and 5 respectively in one transmission. To achieve this, you should program the message in memory buffers as follows from the cmd: prompt type:

CMD: BUF0 XXXXXXXXXXX	....XXXXX CTRL-T 2 <ENTER>
CMD: BUF2 XXXXXXXXXXX	....XXXXX CTRL-T 5 <ENTER>
CMD: BUF5 XXXXXXXXXXX....	XXXXX <ENTER>

Where XXXX is the desired text you wish to program into the memory buffers.

In the example above the CTRL-T 2 does not mean you type CTRL-T 2. It means you hold-
