Section Five – Adjustment and Testing
•
Turn the pots fully CCW so we can test the RF
functions without generating power output.
•
Place the LP Filter to the side and cabled up as shown.
Ohmmeter Test
•
Resistance from Red to Black DC Input with switch ON
should be about 500 - 1K ohm.
•
Online/Bypass Switch placed in Bypass position
•
Attach a watt meter and dummy load in series to the
SO239 RF Output connector.
Test Mode Setup
•
Connect XCVR to the BNC RF Input Connector.
•
Set LPF for 160M. Set the XCVR for 160M.
•
Set the XCVR Power Setting for Low Power (about
1W).
•
Key XCVR. The 1W of power should be displayed on
Watt meter and SWR should 1.0:1 Record _____ W
Basic Current Test
•
I recommend a special cable that allows you to easily
measure current. Power Poles are on each end. Plug
the test cable into the multi-meter set to read amps.
The current passing through the red wire registers on
the meter.
Test cable puts the meter in series with the Red wire.
