Hi all,

I received a great amount of comments on my 902 DEMI transverter power
issue.  Sure enought, I had tuned to get the unit on frequency, and that
dropped the LO output down just a bit so it was "on the edge".  There seems
to be a hysteresis to the circuit as it operates a bit different cold verses
hot, then has a problem when cycling the power after being heated up for
some time.

I was able to repeat the issue as well as tune the LO to a point where it
was a happy medium of power output, frequency and stability.  The LO ended
up about 7 kc hight.  No biggie.  Get 9.5 watts output too.

Again, thank you all for your help, I do appreciate it.  Its nice to have
guys on the reflector that have the knowledge and wisdom to help others
discover the secrets of radio building!
