BARRETT 2030 HF SSB TRANSCEIVER

Testing the Barrett 2019 Automatic Tuning Mobile HF Antenna

To test the Barrett 2019 antenna, first select the lowest transmit frequency in the
transceiver and press the TUNE key. The display should show the word "Tuning"
for a few seconds, followed briefly by "Tune Passed" and an indication of the
measured VSWR (Voltage Standing Wave Ratio) value. Check this reading against
the VSWR meter.
Repeat the above test on the highest frequency in the transceiver and on a
selection of frequencies in between at approximately 2 MHz intervals. If the tune
passes at all times the Barrett 2019 antenna is working correctly. The Barrett 2019
antenna tunes to maximise whip current, not minimise VSWR, but the displayed
VSWR value should generally be between 1.0:1 and 2.0:1. However, if the display
shows "Autotune Fail" accompanied by low pitched beeps at any point, the Barrett
2019 antenna has failed tune. Confirm the "Antenna Type" is selected as either
"910 Mobile Antenna" or "2019 Mobile Antenna" in the transceiver Protected Menu
I/O settings field. Check all cables are correctly connected, check the earth cable
from the base of the Barrett 2019 antenna has a good connection to the vehicle
body (not chassis or battery), check the whip fitted is not faulty or incorrect and
move the vehicle if the Barrett 2019 antenna is close to any metal fences, buildings
etc. If the problem cannot be resolved, contact your dealer or Barrett Service
Department for advice.
