VSWR
The amplifier has a high VSWR lockout circuit built in. If the output VSWR
exceeds 2.5:1 then this will be activated causing the high VSWR warning pop-
up to appear on the screen. The amplifier will go to receive. You can clear the
trip by touching the trip pop-up on the screen. PTT is inhibited until the reset is
done. If the rig is still in tx then the amplifier will not turn back on until you turn
the rig back to rx and then tx again.
Check why it tripped! - Antenna fault? Cabling fault? Wrong antenna
selected? No antenna selected?
This trip has been designed to be deliberately invasive as VSWR faults should
be investigated immediately.
Over Temperature protection
If the temperature exceeds a higher threshold level that could potentially harm
the amplifier then an Over Temp lockout will occur. This will inhibit the PTT,
lock the amplifier on receive and the Over Temp warnign pop-up willl appear.
Once the temperature drops sufficiently the amplifier will enable PTT again
bus as with other trips you will have to cycle the rig off and back onto tx if it is
still transmitting.
Note that if you are getting Over-Temp lockouts then the first thing to check is
that the air intakes under the amplifier and/or the rear outlet are not
obstructed.
Other Functions on the touchcreen
There are various other functions available via the touchscreen. Pressing the
settings button (below the on/off button on the RHS) enters a subscreen with
a menu structure thus:
