REAR PANEL CONTROLS & CONNECTORS
10.PTT Phono Jack
This input jack may be used to provide manual trans- mitter activation using a footswitch or other switching device. Its function is identical to the [MOX] button on the front panel. The same line is available at the PACKET and RTTY jacks for TNC control.
11.EXT ALC Phono Jack
17.+13.8V Phono Jack
This output jack provides regulated, separately fused 13.8 VDC at up to 200 mA, to power an external device such as a packet TNC. Make sure your device does not require more current (if it does, use a sepa- rate power source). Attempting to draw more power from here will blow the internal fuse behind this jack. Should this occur, replace the fuse (as explained on page 114).
This input jack accepts
12.PATCH Phono Jack
This input jack accepts transmitter audio - either AFSK or voice - for transmission. This line is mixed with the microphone audio input line, so the microphone should be disconnected if using this jack and mixing is not desired. Impedance is 500 ~ 600 Ohms.
18.RX ANT Phono Jacks (In/Out)
These antenna jacks are provided for connection for a separate
19.TRV Transverter Drive Output Jack
This jack provides a low level RF output for use with a transverter. Maximum output is approximately 100 mVrms at 50 Ohms

15. GND Terminal Post
Use this terminal to connect the transceiver to a good earth ground, for safety and optimum perfor- mance. Use a large diameter, short braided cable.
16. BAND DATA DIN Jack

20. TX GND Jack (normally disabled)
When enabled by the [LIN] switch, this output jack connects inside the
Maximum ratings for these relay contacts are 500 mA @ 100 VAC, 200 mA @ 60 VDC or 1 A @ 30 VDC. Before connecting an external device, make sure its switching requirements will not exceed these limits. If your amplifier requires higher current, or has higher voltage switching requirements, an external switching device must be used.
21.LIN Linear Amplifier Relay Switch
To enable the TX GND jack when you are connect- ing a external linear amplifier, move this switch to its “ON” position.
22. DC IN Jack
