TUNE switch blinks rapidly and the TRX and AMP LEDs are turned off. Depressing the
AMP TUNE switch before the pulser times out immediately terminates the pulsed tone.
A tune level trimpot on the microcontroller circuit board in the StationPro II
control unit sets the appropriate audio level for the pulsed tone. The correct procedure is
to place the selected transceiver in the SSB mode and turn on the pulser. The level
trimpot is adjusted to give a mid-scale ALC reading on the transceiver’s ALC meter.
5. Networking Multiple StationPro IIs: Up to three StationPro IIs may be
networked, permitting a total of nine transceivers and nine amplifiers to be controlled
(three on each operating desk). Selecting any of the nine rigs will transfer control to that
rig while taking the other eight rigs off-line. The antenna coax line is automatically
transferred to the selected radio, and the key, microphone, speakers, etc., on the relevant
station desk are transferred to the selected radio. The StationPro IIs on the other desks are
deselected and their status is displayed on their respective LCDs.
Pressing any transceiver or amplifer switch on an “off line” desk will activate that
StationPro II and take off line the previously active StationPro II.
There are additional considerations associated with networking multiple
StationPro IIs. Because this topic will be of interest to only a small number of amateurs
having very complex stations, the details of configuring networked controllers are to be
found in a separate maual:
Networking StationPro II Configuration Manual.
VIII. A Final Comment from W8ZR
The philosophy underlying the design of the StationPro II is that an initial
investment made in planning and organizing one’s station will pay handsome dividends
in convenience, time savings, and operating pleasure. The ability instantly and reliably to
switch between rigs means that that more time can be spent on the air enjoying the
hobby, and fewer frustrating hours spent crouched behind the operating desk, debugging
dead connections and miswired cables, and worrying about inadvertently throwing the
wrong switch. The StationPro II and its little brother, the StationPro I, have brought for
their designer a new enjoyment and satisfaction to amateur radio. It is sincerely hoped
that other builders will experience this same enjoyment and satisfaction.
