[Elecraft] Loose buttons

[Dragan 4O4A]

Don at all,

Thanks for help.
I fixed it by placing a small piece (6x6 millimeter) rubber, about 3mm 
thick.
It's stiff enough to prevent movement of PCB. Now, feeling is much better.

BTW, I don't have a problem with this "rubber buttons feeling".
Get used to it during Spectrum 48K time :))

73, tnx
Dragan, 4O4A
