Brian,

Ah, yes.   This refers to the initial setting of the transmitter oscillator=20
frequency.   This pitfall can be avoided by using an accurately calibrated H=
F=20
receiver to make the setting rather than looking for a particular reaction d=
own=20
in the receiver's discriminator circuit as prescribed in the manual.   I use=
=20
my 51J4 for this but a BC-211 would probably work just fine too.  =20

Takes sixteen (16) trimmer adjustments to set up a channel in the 669 and=20
then a final PA adjustment when the chassis is put back into the cabinet and=
=20
hooked up to an antenna.   The manual says that with practice, 10 minutes sh=
ould=20
be enough time to setup a new PAIR of channels.   Optimistic in my experienc=
