                                                                   Side
Tone

When using the HW-16 with a VFO sometime a partial operation of the
sidetone oscillator takes place due to an increased loading on the bias
voltage.  This can be corrected by changing R-69 from a 120K hom resistor
to a 220K ohm resistor [PN 1-29].  Also, the original schematic shows
R-16 as a 4700 ohm resistor which is incorrect.  R-16 should be shown as
a 5600 ohm resistor.

			Resistor Failure

Due to repeat failure of a resistor in the field, the following change
should be made
in all units being serviced:

CHANGE:  R21 22K 1 Watt to 2 Watt [PN 1-11-2].
