The setup is as shown above. the SP2 is on the left. The RF Box is in the middle and an Array Solutions antenna analyzer (AA-200) and a VOM were alternately fed into the transceiver SO239s. The amplifier inputs and outputs were jumpered.
All continuity checks through all combinations show less than 0.2 ohm resistance.
All SWR tests for all combinations show less than 1.08 SWR. The SWR calibration run direct into the analyzer is less than 1.03
The SP2 is fully functional in terms of RF switching.
