TUNER OPERATION

P L A C E T U N E R I N A U T O M O D E W I T H G R E Y M O D E B U T T O N
1. CONNECT the transceiver to the RF INPUT
chassis connector at the rear of the back panel
2. CONNECT a dummy load to one of the coax
outputs or your desired antenna
3. APPLY a single tone level greater than 5 watts
(use FM MODE) typically 5 to 50 watts
4. DISPLAY will indicate Frequency, Power Level,
SWR, and Numerical value for C and L
NOTE: To execute a tune sequence at another band or frequency lower the
power of the transceiver or any other transmitting device to low power
and change frequency and the tuner will immediately follow to the
new location. You can also click the PTT button on your microphone in FM
MODE and accomplish the same at the lowest power level
TUNING THE HF-AUTO
Applying only a short burst of single tone power to the HF-AUTO will
allow the tuner to pretune to a memory segment containing the desired
frequency. ANOTHER application of RF Power must be applied to complete
the nal tune condition where high power may be applied. You can also
apply single tone power continuously until the nal tune cycle has compled
and get the same result. Trying to tune at high power without executing the
nal tune condition could damage the tuner.

REMOTE OPERATION
PALSTAR will o er a fully remote version of the base version in the near
future. However, in certain cases where there is DC power available at
a reasonable distance you can operate this base version in the AUTO
MODE. Other functions would of course not be available.
The base version is frequency sensing you need only to insert a
metering device that could monitor re ected power in the
transmitting location.
