CHAPTER 3
RADIO INSTALLATION
3.1 Overview
This chapter describes how to connect the PK-900 to your radio
receiver or transceiver. To receive digital transmissions you must
connect the receiver audio and Ground to your PK-900. To transmit
you will have to add connections to the microphone or low-level
transmit audio and to the Push-To-Talk (PTT) circuit of your
transceiver.
The most convenient way to connect your transceiver is through a rear
panel ACCESSORY Connector (if your transceiver has one). You may also
use the Mic connector if you prefer. Appendix E contains connections
for many specific radios. MAKE SURE THAT YOU REMOVE POWER FROM THE
PK-900 AND YOUR RADIO BEFORE MAKING ANY CONNECTIONS.
3.1.1 Equipment Required
You will need the following for complete transmit/receive connections:
o your PK-900 Data Controller, computer or Computer Terminal and
software as discussed in Chapter 2 of this manual;
o AEA-supplied shielded cable for each radio you wish to connect;
o your radio and its power supply;
o microphone or accessory-plug connector(s) required by your radio;
o soldering iron and solder if the radio connectors require it;
o wire cutters and strippers and/or a small pocket knife;
3.2 Receive-Only Radio Connections
If you are a Short Wave Listener (SWL) or only interested in receiving
signals, the connections to the PK-900 are simple. Even if you are
planning on transmitting and receiving, you may initially want to just
receive to become familiar with the PK-900. Taking a little time to
tune in and "read the mail" is an excellent way to get acquainted with
the various modes before going on the air.
For receive operation, only the audio from the receiver or transceiver
(and Ground) needs to be connected to the PK-900. This can often be
accomplished by simply connecting the included 3.5 mm audio cable
between the PK-900 and your receiver as shown in figure 3-1 below.
The audio cable can then be connected to the External Speaker/Earphone
jack on the radio you will be using.
NOTE: Some Short Wave receivers come with low-level outputs
designed for use with a tape recorder. These outputs
typically do NOT have enough level to drive the PK-900.
