Connecting PGXL amplifier to ICOM transceiver

While PGXL is ‘native to the Flex environment,’ interfacing with any radio transmitter is easy and straightforward.

In the case of ICOM, the communication is via CI-V connection. Done in no time, in 3 easy steps.

1. Physical connection

Two cables are required. The first one is a standard keying cable with two RCA connectors. One end plugs into the ICOM’s SEND jack and the other into the PGXL PTT IN. The PGXL PTT line is insulated from ground, so keying cable has to have its own ground.

The second cable is CI-V with two 3.5mm stereo audio connectors. One end plugs into ICOM’s REMOTE and the other into PGXL CI-V. Note: Make sure that the 3.5mm plug actually plugs in all the way. If you are using a ready-made cable with moulded connectors, remove 2-3 mm of plastic from the end that plugs into the amplifier side.

2. CI-V settings at the transceiver’s end

Settings -> Menu -> Connectors -> CI-V: set baud rate to 9600. Note the default CI-V address is 94h. Scroll down, and set CI-V output for antenna to ON.

3. CI-V settings at PGXL

While the parameters could be set directly on the amp touchscreen, it is more convenient to do so through the PGXL app. Set as per below.

The final screen: PGXL is reading data from ICOM VFO.

There is one more important setting before keying and transmitting: to set the radio’s keying delay to avoid hot switching. In the transceiver, go to Menu -> Set -> Functions -> TX Delay -> HF & 6M to 30 mS.

This completes the setting for Port A. If you wish to use the amplifier in two radio configuration, set Port B accordingly.
