[Moon-Net] FT-736R how to adjust 23cm frequency?

I am pretty sure the MO on the main IF unit is the one to aim for
I had 2 x 736rs with the same issues
If I remember the MO is multiplied – so a few Hz off at 144 is much larger at 432, is larger again at 1296
I ended up stacking polystyrene around the master oscillator can and trying to keep the radio as stable as possible by leaving it on or turning it on well before operating
I am pretty sure from memory the master osc drives all modules hence the issue
Kinda hope that helps!

This evening we tried to calibrate my FT736R on 23cm, the frequency is
2,6KHz off. (if you watch the pictures we set 1296.300 and counter says
Very annoying in E.M.E....
The 144MHz and 432MHz transmitters are +/- a few Hz bang on frequency.
I opened the optional 23cm module to find out which screw to turn but,
nope... no result
these are photos from the module
anyone done this before?
I tried Q14, nope
TC01 caused a fast frequency drift of 300KHz downward so quickly put it back
Would be soooo nice to have my rig on frequency
Best 73! ON5GS Dirk
