[Motorola] need info on Moto HT210

[J C White]

Anyone have diagram of the Moto HT210?
Actual Model is H33MMB1114A

I believe there is an antenna adapter for this HT so that
one can get rid of the nearly useless duck with the small 
screw base.  I also understand that CTCSS and another 
channel can be added.  For now I just want to check out
5 of these and get them in tip top functioning; then I can
consider mods.

All assistance will be greatfully appreciated
