KENWOOD TS-940S RECIPROCAL MIXING NOISE
In early March I talked to someone at International Radio
regarding the reciprocal mixing noise problem with the
Kenwood TS-940S.  I had been in the process of installing the
fix described in your newsletter (late 1986 issue) and found
that it had already been installed on my TS-940S (S/N
7100269).  The factory installation had one problem, the
resistors used for R120/R129 were color coded for 900 ohm
(close enough to the 1K in the newsletter), but in actuality
measured 465 ohms.  Apparently, Kenwood had gotten a bad
batch of resistors from some supplier and had not dicovered
the problem.
At the time you indicated that was the first report you had
received of the resistor value problem and recommended that I
contact Kenwood. I called them and was told that they had not
heard of the problem before.  They also stated that a new fix
for the reciprocal mixing noise problem had been developed
and was described in a Service Bulletin dated March 2, l987.
I requested a copy of the bulletin and have attached a copy
of it to this letter for your information.  (See Issue No.
76, Pg. 30 and 31 for Kenwood Service Bulletin No. 917 and
schematics pertaining to this subject.)
