Controlling an Icom PW-1 Amplifier

The Icom PW-1 Amplifier can automatically track the frequency of an Icom transceiver if

  • The PW-1 and transceiver are connected to the same CI-V bus
  • The transceiver's CI-V Transceive setting is enabled

During an initial programming step, the PW-1 learns the transceiver's CI-V address. From then on, the PW-1 monitors the CI-V bus for new frequency messages emitted by the transceiver when it QSYs with its CI-V Transceive setting enabled, and adjusts its frequency accordingly. If 10 seconds elapse without a "new frequency" message, the PW-1 begins sending the transceiver "report frequency" directives via the CI-V bus.

With no other devices connected to the CI-V bus, this arrangement enables the PW-1 to track the transceiver's frequency. However, if the user wishes to run a PC-hosted transceiver control application to support logging, digital mode operations, DX spot collection, etc., the required connection of a PC-controlled CI-V interface to this CI-V bus generates collisions between PC-initiated CI-V commands and the transceiver's responses to the PW-1's report frequency commands. Unfortunately, the PW-1 lacks the logic required to detect and reject CI-V messages damaged by collisions; the result is that the PW-1 fails to accurately track the transceiver's frequency.

Commander's Secondary CAT Port can be configured to interact with a PW-1 connected to a private CI-V bus, enabling the PW-1 to accurately track the primary transceiver's frequency. This configuration allows the PW-1 to accurately track the frequency of any primary transceiver, not just Icom transceivers. If your transceiver is an Icom, you must establish this connectivity:

If your transceiver is not an Icom, you must establish this connectivity:

Recent Icom transceivers like the IC-7700 and IC-7800 can be directly connected to an RS-232 cable without need of a CI-V interface; the IC-7200 and IC-7600 can be directly connected to one of a PC's USB ports, eliminating the need for a serial port, RS-232 cable, and CI-V interface. The CI-V interfaces required by older Icom tranceivers and by the PW-1 can be [:ConnectingIcom: acquired or assembled]. Some non-Icom transceivers cannot be directly connected to an RS-232 cable, requiring a [:TransceiverConnection: level conversion interface].

With the physical connectivity established as shown above,

  1. configure Commander to control your [:TranceiverControlAlinco:Alinco], [:TranceiverControlElecraft:Elecraft], [:TransceiverControlFlexradio:FlexRadio], [:TranceiverControlIcom:Icom], [:TranceiverControlKachina:Kachina], [:TranceiverControlKenwood:Kenwood], [:TranceiverControlTenTec:TenTec], or [:TranceiverControlYaesu:Yaesu] transceiver via Commander's Primary CAT Port

  2. verify that Commander can track and control your transceiver's frequency and mode
  3. configure Commander's Secondary CAT Serial Port panel on its Configuration window's Ports tab

    1. set the CAT protocol selector to PW-1

    2. set the CI-V Address to 74

    3. click the Follow and Lead Primary button

    4. set the Port# to the COM Y

    5. the Baud selector to 9600

    6. set the Word selector to 8

    7. set the Parity selector to N

    8. set the Stop selector to 1
