Great suggestion... I will check the historical screw mark on the shaft against where I have it sitting now and have a bit of a play with that and report back.
Currently the dial is accurate - set initially using the sig gen and then tweaked using known stations at the top and bottom of the dial. Its pretty bang on through the range at the stations I listen to.
The IF frequency is set pretty accurately I think... I use my digital scope to check the frequency of the sig gen (a leader LSG-200). I generally leave this connected throughout the alignment to check the frequency. Its a bit dodgy on higher ranges (I think thats the sig gens fault, not the scopes) but seems fairly accurate and stable at 460kHz.
Cheers
