IIRC, he might be having some family related business to take care of; might take awhile before he is back to normal business. Just keep trying.
Or you might try 'The Radio Shop Supply' in Ramona CA; ask for 'Chip'.
They are the authorized factory repair station for RCI/Ranger radios:
RADIO SHOP SUPPLY/RANGER USA PARTS & SERVICE
1672 Main Street Suite E #228
Ramona, CA 92065
(760) 440-0125
Or Chris Holland (another xlnt tech that works on many brands of radios) at:
The Radio Shop
4045 E Guasti Rd
Ontario, CA 91761
(909) 390-5056
Either one would be a fine choice; there are some others too. Had some work recently done to a RCI-2995DX base radio by Chip. Seems to be working quite well now. Chip @ 'The Radio Shop Supply' used to work for Motorola and his expertise/familiarity with RCI/Ranger radios is extensive.
Chris Holland does warranty work for Magnum/RF Ltd radios, and is also quite the radio guru with a LOT of experience.
There are some other shops closer to you that are equally competent; someone is bound to post that info up soon. So; keep checking back here.
