Default Re: Help needed with - Racal Dana 9081

Hi Paula , Peter

Few further results:-
IC6 pin 11 on scope shows 12v
TP15 shows 8.13vdc on dvm but 12v on scope?
I then went through the band selector from 5khz to 60hz and noted the stepsas follows:-
5hz shows 40khz steps so X8
10khz shows 40khz steps x4
20hz shows 40khz steps x2
6.25khz shows 50khz steps x8
12.5khz shows 50khz steps x4
25khz shows 50khz steps x 2
50khz shows 50khz steps x1
15khz shows 60khz steps x 4
30khz shows 60khz steps x1
60khz shows 60 khz steps x1

So each of the above on band 1 is
8,4,2, 8,4,2 the changes to 1,4,2, then goes to start again at 1,4,2 but maxs out at 60khz ch setting so stops at x1
Not sure if this is useful but as a pattern thought it may indicate channel spacing switch is fitted correctly?
