TUNER OPERATION

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 final tune condition where high power may be applied. You can also

apply single tone power continuously until the final tune cycle has compled

and get the same result. Trying to tune at high power without executing the

final tune condition could damage the tuner.

PALSTAR will offer 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 reflected power in the 

transmitting location.
