[Heathkit] SA-2060A

[Michael Melland]

Bob,

While reading the SA-2060A manual gives you the idea
that the "bypass" position removes the tuner from the
circuit it reeally doesn't.  The "bypass" position
sends the transceiver's output only to the "bypass"
SO239 on the rear... which was meant to be used for a
dummy load.  If you want to send a signal to one
antenna and either choose tuner in/out here is a
way...


You need: 

1ea, Amphenol - 83-1AP, 90 deg UHF Angle Adapter
1 ea, Amphenol - 83-1T, UHF T-adapter
1 ea, Amphenol - 83-877, UHF straight adapter,
(plug-plug)

Screw the straight adapter onto the end of the 90
degree adapte.  Screw one end of the T adapter onto
the other end of the straight adapter... sort of makes
a connector shaped like (forgive illustration):

_|_  =  T
_    =  Straight Adapter
_|   =  90 deg adapter      _|_ _ _| 

Leave the connections loose for now... screw the free
end of the 90 deg angle connector onto the "Antenna 1"
SO239 and the T adapter onto the "Bypass" SO239.  Now
attach your antenna coax to the other end of the T
adapter. Amphenol connectors fit this gap perfectly
once tightened... others may not.  tighten all the
connections normally...

Now the Antenna 1 position acts normally and the tuner
is always in-line to the antenna.  Whwn you accept
Bypass the signal is routed to the antenna via the
bypass SO239 to the T and the tuner section is indeed
out of the circuit.  

I liked this method as no alteration to the tuner is
necessary... and it causes no issues with amplifiers
etc...
