Hello Pete,

alignment instructions for the reference oscillator:

-With the TEST message displayed, press the MODE button. Connect a
frequency counter to TP2 (Local Osc).

-Adjust TC1 (on the control unit) for a reading of 45.00000 MHz +/- 20 Hz

alignment instructions for the heterodyne oscillator:

-With the TEST message displayed, connect a frequency counter to TP6 (Audio)

-Press the MODE button. Adjust TC2 for a reading of 3234 Hz +/- 10 Hz.

-Press the FAST button. Adjust VR1 for a reading 8 Hz above (3242 Hz)

-Repeat the procedure


My HF-150 (built around 1995) works very well after repeating that
alignment procedure a few times.
