Thank you very much! I went through this alignment procedure and everything
is fine now. I needed to replace the 4569 divider chip on the display board
before I could do the alignment. This chip had a thermal
problem..........after 15 minutes of operation, the BFO injection frequency
would shift about 3kHz. After replacing the chip and going through the
alignment sequency, I have a good HF-150. Thanks again!

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.

Hi Pete,

if you should need any other information from the HF150 technical manual
just send me an email.

Thanks Arnie......................a fellow in England sent me a scanned PDF
of the manual. You know, I've also got an AOR7030, but the HF150 does seem
to have a much better low end response remeniscent of the old Philco console
radios.
Thanks again!

Pete
