[1000mp] 1000MP Clarifier Problem

Sat, 22 Feb 2003 16:09:03 -0500

Hi Pawel!  Thanks very much for the information.  I am a new subcriber to
the 1000MP email list and have since found one other posting from several
months ago about the clarifier.  I think I'll have to buy the service
manual.  Yaesu charges $70.00 per hour to do service work!  The manual and
my time would be much cheaper.  Thanks again.
