West Mountain Radio Operating Manual
INTRODUCTION
Footswitch / Keypad Port
This RCA phono jack can be used for a conventional footswitch or analog
keypad. You can program this jack so that multiple taps on a footswitch (up to
three) will trigger serial input signals on the DXpro Control Port. These can be
monitored by suitable software and an action performed such as playing back a
voice keying wave file.
Optionally a four button analog keypad can be attached to trigger the serial
input signals. A readymade analog keypad product is available from West
Mountain Radio.
Sequencer Support
The DXpro has two ports for sequencer interfacing. The SEQ-TRIG port is an
output and can be used to start a sequencer’s timing loop.
The SEQ-END port is an input and would be connected to the output of a
sequencer to signal to the DXpro that transmit is now safe.
During this time PTT/CW/FSK is suppressed on the DXpro. Logic levels for the
sequencer ports can be programmed either active high or active low.
Squelch (COS) Support
There is a dedicated squelch input which can be used for advanced
applications such as EchoLink or for repeater announcements.
Optional ClearSpeech
®
Module
Internally, a header is provided to install a CLRmod DSP audio processor. This
can be used in a similar way to our CLRspkr and CLRdsp products. A good
use for this would be to reduce received HF noise when operating remotely
using the DXpro. The CLRmod DSP filter level, tone, & volume controls can be
changed via software
RTTY FSK & CW Keying
The DXpro has outputs for real CW keying and FSK RTTY. In addition there is
a “right-channel audio to FSK” circuit which allows some digital mode software
(such as FLdigi) to produce true FSK.
In a similar fashion, true keyed CW can be output from audio based Morse
Code software.
12v Output
A swit12v DC output is provided which can be used (remotely if
needed) to turn a small station accessory on or off.
