Bert,
This looks very interesting. Have you been able to determine the
actual error between the receiver's "tuned to" frequency and the
1850.000.00 Hz audio tone error out of the receivers audio for upper
and lower SSB? This could make a good group project kit.

solution

Hello Everyone,
I have spent the last few weeks modifying the HP 3586 Selective
Level Meter. The
intent was to modify the unit and reference the SSB product detector stage to
the internal reference. This would make the entire SLM locked to the 10MHz
reference, whether internal or externally fed.
I have completed the modification with satisfactory results. I use a
DDS-Based
Function Generator 16-pin IC and a small 8-pin PIC micro. For more detail,
visit my website at http://ve2zaz.net/HP3586_AD5962/HP3586_AD5962.htm .
This has been a very good exercise from a DDS perspective and I have
learned a
lot on the topic. I would be interested in hearing from those who
proceed with
the mod.
Thanks,
Bert, VE2ZAZ
