[1000mp] MKV RX Relay Problem

[D. J.]

I have three of them I ordered from Yaesu to replace the intermittent  
ones from the factory.  Looking on top of one of the relays I read:   
NAIS 50210 TX2-12V ATX-203, then what looks like a circle with SA  
inside, then some sort of a symbol and then Japan.

Sure are tiny little relays.  I wonder if drilling a small hole in  
them and squirting some Deoxit would make em last longer.  If I  
remember they were around $5 each and shipping was another $10 or  
$12.  I have not installed them yet because the MKV seemed to have  
fixed itself.  What a rig, self healing.
