quickly tell you which way to go! Bars to the left of center indicate you should
tune higher, while the other side of center means to tune lower.
Many BBS station forward traffic on HF at the above frequencies. Call CQ a
couple KHz away from such channels. If you can't raise anyone, call CQ on one
of the above frequencies, but QSY immediately after establishing contact! Be
careful on 20 meters especially that you don't operate +/- 2KHz
around 14.100 MHz (you will cause interference to propagation beacons and
give packet a bad name...)
HF Packet Operation Hints:
1. Try to keep all packets below 80 characters in length.
2. Set MAXFRAME to 1. This will minimize transmission time.
3. Avoid multiple connections and digipeated packet operation.
4. Qsy away from the standard calling frequencies as soon as possible.
5. Set FRACK to a sensible long value.
More detail on HF packet operation is discussed in the next chapter in this
instruction manual.
FAX OPERATION
The MFJ TNC is capable of receiving 2-level FAX. FAX receiving is possible
only if you are using an optional terminal progrom provided by the MFJ Starter
Pack. The MFJ TNC supports only the Weather FAX mode (120 line per
minute) format.
If you are interested in FAX receiving and transmiting, we suggested that contact
MFJ Enterprises, Inc. to inquire about about the MFJ TNC muiltmode data
controller which is capable of receiving and transmitting up to 16 gray-level.
MFJ also offers model MFJ-1214 for IBM and compatible PCs. It is capable of
transmit and receive 16-levels FAX and color FAX. It also supports RTTY and
CW modes.
MFJ Enterprises, Inc. offers terminal software for some computers to support
this operation. This software allows you to print FAX pictures to screen in near
