SG-239
Quick Start
Installation:
To quickly install your antenna coupler you will need the
following:
1.An HF radio with 1.5 to 200 watts output.
2.An HF antenna with a wire feed. Minimum length of 9
feet (7-30 MHz @ 100W), 40 feet (3-30 MHz @
200W) or 100 feet (1.8-30 MHz @ 100W).
3.A good ground radial longer than the antenna for the
antenna and coupler.
4.+12 VDC and ground for the coupler.
5.SmartLock coupler controller (optional).
Power supply can be same as the radio or supplied by ra-
dio DC switch supply line.
Operation:
1. Turn on Radio. Apply +12 VDC power to the coupler.
2.As power is applied, coupler should make one “click”
sound and is in the bypass (un-tuned) state.
3.To tune, speak normally, whistle or use CW (CW is
recommended).
4.Tuning should be done at full power for automatic.
Clicking is heard.
5.When tuned, clicking stops, the tune LED turns on and
output tune line goes low. SG-239 can be tuned manu-
ally at any transmit or receive frequency, five memory
bins are assigned for receive only.
6.The coupler PI network can be manually tuned and
stored in memory by using switch S1 and pushbuttons
S2-S8.
