AM/FM POWER SET PROCEDURE
TROUBLESHOOTING
Bypass SWR: (as seen on the TFT display)
The LA-1K is in
BYPASS
to protect itself against high SWR. This indication
appears when the SWR is (or has been) over 2.5:1 during a transmission.
Transient faults such as antenna arcing can show a low SWR after the fault
event while the transmitter is still keyed up.
Solution:
Make sure the correct LA-1K antenna connector is selected.
Verify that your HF-AUTO or other tuner has obtained a good match while
the LA-1K is in standby. Attempting to tune at high power can cause this
alert.
With some auto-tuners it may be necessary to select manual mode after
obtaining a low SWR to prevent unwanted tuning in the middle of your
transmission.
If antenna arcing or loose connections are suspected, try the ampli er
on a dummy load. If it works normally there is likely some type of
intermittent SWR problem.
For AM mode set the carrier no higher than 250 Watts. AM peak power is
4 x the carrier level.
