[Boatanchors] RAL switch cleaning

[wf2u at ws19ops.com]

Ian,

I have 2 RAL's  and a RAK (the LF receiver). They all work fine, but  
the bandswitch doesn't have that positive "clunk" either on either of  
them.
I didn't look into the switch mechanisms to see whether it's normal,  
since it's the same feeling with all of them, I assumed they're made  
this way.

It's time though to spray the switches as they're a bit noisy and  
sometimes I have to wiggle them a little to make good contact.

I usually use the long thin nozzle which I can stick into small holes  
and spray in the general direction of the part, if the part - or wafer  
in this case is not directly accessible. I don't remember whether  
there are any holes over or around the inaccessible switch sections in  
these receivers...
