INSTALLATION:      

Location/Connection

 

The transceiver should be placed in a convenient operating location 
close to an AC power outlet and the antenna lead in cable(s). 
The transceiver is powered with the AC power cord set. Proceed as 
follows to complete all necessary connections to the transceiver. 
 
1. Your transceiver has standard antenna connectors of type SO-239 

both located on rear panel; for easy connection to standard PL-
259 coax plugs. If the coax antenna cable must be made longer, 
use coax cable with impedance of 50 ohms and use only enough 
cable to suit your needs. This will insure a proper impedance 
match and maximum power transfer from the transmitter to the 
antenna. 

 
2. AC Power Operation: Use 120 volts AC. 

 

Noise Interference

 

There are several kinds of noise interference you may encounter in 
fixed operation. Some of these noise sources are; fluorescent buzz, 
nearby commercial broadcast, electrical appliance, lawnmower, and 
electrical storms, etc. Commercial products are available to reduce 
interference from these sources. Consult your dealer or professional 
amateur radio supply shops.
