[R-390] RF deck removal

[Roger Ruszkowski]

Alan,
 
Looking ahead is the RF band switch.
About six wafers and six contacts on each wafer.

With the RF deck out, adjust the RF band switch by eye ball.

Tune both up and down the full range of megahertz.
As the Geneva gears rolls the switch one contact,
look at the wafer wiper relative to the wafer contact.

Look at all the points.
Now its a judgment call of the eyeball.
Set the switch for the best contact of all the wipers to all the contacts on all the wafer sections. 

The adjustment will be a very very small amount to be optimum.

Your worse fear is that some where in the past the switch was not well adjusted
a some corner of a contact is burnt off giving you less metal than you would like.

You do not want to get into tinkering with wafers and contacts.
Just accept what you have and set it the best adjustment point you can.
It has been good enough for the last 60 years.
It is still good enough to work.
Your goal is not to make the situation worse buy leaving it in a less than best it can be state.
