TROUBLESHOOTING
TX Wait: (as seen on the TFT display)
This message appears on the display when the PTT line is grounded
but no RF is present. RF must be applied with PTT line low to key the
ampli er to the transmit state.
Won’t amplify or auto-band switch when transmitting:
Solution:
Make sure that the PTT cable is connected to the transceiver. This is a
REQUIRED
connection. Note that TX will show on the display when the
PTT connector sees a ground. Some transceivers must have their PTT
keying output enabled in the transceiver menu settings.
Low SWR on transceiver, high SWR on the LA-1K
Solution:
Always disable (bypass) the auto-tuner in your transceiver when driving
any ampli er.
The transceiver’s autotuner can not match loads connected to the
amplifer’s output.
