800-BPF Control
Manual Switch for Model 600
Thank you for choosing the Dunestar Model 800-BPF Bandpass Filter Se-
lector. The 800-BPF controls all six of the band filters available in the Model
600 Remote Switchable Multiband Bandpass Filter. With just a few simple
connections your 800-BPF will provide you with full selection of your system.
INSTALLATION:
The 800-BPF enclosure is a two-part clam shell design. To gain access, remove
the two sheet metal screws. There is one on each side of the enclosure. The
control cable is fed through the opening on the real panel. Placing a loose knot
in the cable where it passes through the rear panel will relieve strain on the ter-
minals should the wire be pulled after installation.
Cable connections are made directly to the terminal studs on the circuit board.
The terminal markings correspond to the cable coming from your Dunestar
Model 600. For ‘Positive’ keying (Model 600 is shipped standard jumpered for
‘Positive’), +12VDC input is attached to the terminal marked “C”, the -12VDC
(GND) goes to terminal “G”. “G” is also used for the ground lead coming from
the Model 600. Terminals “1”, “2”, “3”, “4”, “5”, and “6” are for the select
lines. +12VDC and –12VDC are reversed if you are using a Model 600 jump-
ered for ‘Negative’ keying.
A 12VDC supply (100-ma maximum) is required. This can be a wall plug-type
universal supply or can be supplied from the station 12VDC auxiliary supply.
It is recommended that a 1/4-amp fuse be placed in the +12VDC supply line
for protection. (we have provided one for you)
If you require additional information or help, please feel free to call, email or
write.
DESCRIPTION:
The 800-BPF consists of a rotary switch to select the band filters available in
the Model 600. The default or OFF (no power applied) selection provides a
by-pass or ‘failsafe’ in the event of power supply or cable failure. This pass-
es the transceiver output straight through to the amplifier or antenna and is
also useful to receive or transmit outside the range of the filter sections, as in
listening to WWV (refer to the schematic).
