[Elecraft] Grounding K2 Mic Connector

[Don Wilhelm]

Roy,

I do it on all K2s I work on which have  the KSB2 option installed.
I always solder to the mic jack and to the ground plane right below it 
(scrape away a bit of the green solder mask material).  Yes, it takes a 
good deal of heat to bring the jack shell up to temperature.  Heat it 
with a 'big gun' until the solder flows on the shell.  I solder on a 
small "L" shaped piece of wire - leave it long until after it is 
soldered in so you can hold onto the wire with pliers..

Over time these springs tend to oxidize preventing a good contact.  I don't like using the wire loop method of grounding as it is a variation of my method.  I would like to know if the mic jack metal will accept solder with a reasonable amount of heat using a 100/140 watt soldering gun.  Has anyone grounded the mic jack this way?
