VOLT trip off-line

Ensure power supply maintains voltage greater than 11.0VDC

under load. Check DC cable connections.

VSWR trip off-line Check integrity of antenna and feedline connections.

Check for evidence of arc-over or dielectric breakdown

of feedline. Ensure antenna is resonant (<2:1 SWR) at

the desired operating frequency.

Amp TEMP led is on. Reduce drive level or duty-cycle. Ensure fan unit is

operating properly.

No PTT Keying Ensure transceiver, amplifier and DC supply all utilized a

common ground.
