Memory Button
This button allows you to choose two different groups of filters with the Filters
switch. This button functions any time the DSP's power is on and the DSP
button is "in."

With the Memory button "out," the Filters switch picks one of ten Tunable
(front panel adjustable) and Pre-Set (jumper or factory programmed) filters
marked LR/HR through SSTV/FAX/WeFAX.

When the Memory button is "in," the Filters switch picks a memory location
labeled 1 through 10 on the front panel. The DSP processes the signal using
the filter you have stored in that memory location. Page 4-2 gives you more
detail on the use of memory.

Filters Switch
This switch picks the main filter used to process the signal. It is used in
conjunction with the Memory button we talked about above. It functions
whenever the DSP power is on and the DSP button is "in."

Note:

Please remember that when we say Tunable, the main filter's
bandwidth and frequencies can be adjusted by the two front panel
Tunable Filters controls. Pre-Set means the front panel Tunable
Filters
controls cannot be used to adjust the filter. A Pre-Set filter's
mark-space frequencies and bandwidth can only be changed by
removing the cover and re-programming internal jumpers (see page 4-
11).


When the Memory button is "out," the Filters switch selects one of the 5
Tunable filters (LR/HR, BP, 2BP, CW, and SSB) or one of the 5 Pre-Set filters
(RTTY, HF PACKET, AMTOR, PACTOR, and SSTV/FAX/WeFAX).

When the Memory button is "in," the Filters switch selects any one of ten
memory filters you have stored in locations 1 through 10 of the DSP's
memory. The Filters switch also selects the memory position (1-10) where you
can store the last Tunable/Pre-Set filter you're using.

Chapter 5, Filter Description, gives more detailed information on each filter
type available with this switch. Chapter 4, Advanced Features, gives more
details on using the memory.
