[Yaesu] FT2600M MEMORY PROBLEM

Sun, 14 Apr 2002 22:09:15 -0400

I've had this identical problem and have not found a fix.  My radio is long
out of warranty.  Currently the radio is powered directly from the vehicle
battery with a relay to disconnect the battery during cranking, etc. as
suggested by Yaesu tech people.   The reset is related to engine cranking so
use on a bench supply might be okay.  The radio also seems to reset more
often with more memory channels programmed than with just a few programmed.
I can program just two or three memories and the unit will be okay for
months at a time but if I spent an hour or so and program 100 channels it
will reset within the same day.

I've tried adding capacitance to the five volt regulator internal to the
radio that supplies the processor without any improvement.

There is no internal memory battery in this radio to replace as some people
have suggested.

In my opinion there is a serious flaw in the design of the radio that allows
this reset to occur even with reasonable care.

An equivalent new radio is less than $200 so there's a limit on how many
times I'm willing to ship it back for repair.

Its a shame these units have this flaw because otherwise its a satisfactory
radio with good transmit audio and good immunity to intermod from high
powered FM and TV transmitters nearby.

DOES THIS HAPPEN WITH THE FT7100 AS WELL?
WAS LOOKING AT USING THE 2600 AS THE HOME UNIT AND USE A DUALBANDER AS
THE MOBILE.

if the voltage drops to low on vehichel startup it goes blank
all of them do it
the only fix is to turn the radio off when starting engine
you could set the APO to turn off the radio for you

hope it helps      cul de k9wkj
