Pre-Set Filters
We have set the RTTY, HF Packet, AMTOR, and PacTOR filters to the most
commonly used mark-space frequencies and baud rates. If you wish to change
from the factory defaults, you must change the jumpers and program a filter.
You may program these filters to a number of mark-space frequencies (shifts)
and baud rates. The baud rate setting controls the bandwidth of the filter.
Depending on conditions, it is possible to run higher baud rates than are
calculated.
The SSTV/FAX/WeFAX filter is fixed. When you program into this position (no
change of the jumpers is necessary), the Pre-Set filters and CW sidetone (not
those in memory filters) will reset to the factory defaults. See below.
To set mark-space frequency or reset the filters to the factory defaults*:
1. Press and unlock the Power button to "off" and
remove the power plug.
2. Remove the unit's cover (6 screws).
3. Set the jumpers for the selected data filter (see jumper table on next
page). Record the Pre-Set filter settings with the chart on page A-7.
4. Turn the Filters switch to RTTY, HF PACKET, AMTOR, PACTOR, or
SSTV/FAX/WeFAX *.
5. Reconnect the power cable.
6. Press and hold the Program button.
7. Press and lock the Power button to "on."
8. The unit will beep until the Program button is released.
9. Press and unlock the Power button to "off" and
remove the power plug.
10. Set the jumpers back to the Talk tone frequency and Morse code speed
and the auto notch aggressiveness level. (Refer to page 4-8.)
11. Replace the unit's cover (6 screws).
12. Reconnect the power cable and resume normal operation.
