APPENDIX E – SPECIFIC RADIO CONNECTIONS

This appendix provides radio connection information from your AEA data controller to approxi-
mately 400 different models of amateur transceivers.

Each radio listed references a connection figure and possibly a note on connections. Notes are be-
low on this page. Connection figures appear following the table of radios. All PIN type wiring con-
nections are viewed from wiring/solder side of plug.

The wire colors used on the diagrams refer to the wires in the radio cables supplied with your AEA
data controller. The standard minimum configuration will allow operating of all HF modes with your
radio set for SSB operation. When wiring information refers to FSK connections, these connections
allow you to operate your radio in the RTTY or FSK mode, and usually results in a purer transmit-
ted signal and usually allow using narrow fitters not always available when the radio is set for SSB
operation.

Radio Connection Notes

Note 1

Receive audio is not available on the microphone jack of all radios. If you make this
connection and are unable to receive, use the speaker jack on the rear panel of the
radio as a source of receive audio.

Note 2

Your radio may not require a plug with 3 connections, i.e. tip, ring, and sleeve. We
suggest you use the 3conductor "stereo" plug wired as shown so that if you change
radios in the future to another model with this same connections scheme, your ca-
ble will be compatible without modification.

Note 3

Older Icom transceivers which use the 8-pin microphone plug may not have receive
audio connected to the microphone jack on pin 8. In this case pin 8 is unused. We
suggest you make the connection as diagrammed even if your radio does not have
receive audio available at pin 8, so that if you change to a newer model lcom radio
the cable will be ready to use without modifications. If you make this connection
and are unable to receive, use the speaker jack on the rear panel of the radio as a
source of receive audio.

Note 4

If you have difficulty in locating an 8-pin DIN plug for this connection, a 5-pin DIN
may be used in its place. A 5-pin DIN has all the required pins for connections to
Icom HF rigs, because pins 6, 7, and 8 are not used. The numbering and arrange-
ment of the remaining pins is unchanged.

Note 5

In most Ten-Tec radios where an FSK input is provided, a pull-up resistor to a posi-
tive power source is required to produce proper function of the FSK keyer in the ra-
dio. Contact Ten-Tec for recommendations on how to add this resistor to the radio to
which you are connecting.

Note 6

This connection only valid with PCB-88, PK-96, DSP-1232, DSP-2232, and PK-900
Radio Port 2 only. This connection is also appropriate for use at 9600 baud applica-
tions with radio in DATA mode.

Note 7

This connection only valid with PCB-88, PK-96, DSP-1232, DSP-2232, and PK-900
Radio Port 2 only.

Note 8

This radio uses negative push-to-talk signaling. Change the appropriate keying po-
larity jumper in the data controller. See installation chapter for details.

Note 9

Based on our experiences with this radio and its RF susceptibility we recommend us-
ing this connection diagram if you choose to use the ACC2 connector. This radio has
shown susceptibility to entry of RF on pin 11 of the ACC2 connector, so we do not
connect the AFSK (White wire) in this diagram. Use the FSK mode of this radio
when you wish to operate data modes.
