/\ ANTENNAS
No outside antenna or ground is normally re- _
quired for standard broadcast (AM) reception, as a KEAR OF CHA555
loop antenna is located inside the cabinet. An~
tenna connections are shown in Figure 1. In loca-
tions ahere additional pick-up is desired, an ex- ,
ternal antenna may be connected to the clip marked WW-V-E

An PM loop antenna, mounted inside the cabi- G (R) ? G

l. The following Hd alignment procedure, using an
PM signal generator and an oscilloscope, is to he
preferred because the actual response pattern may
be observed on the scope and adjusted for best
synlnetry and maximum amplitude.
2. Connect the vertical input terminals of the
oscilloscope between the chassis and the junction
of resistor R-17 (47K) and capacitor C-21 (1000 mmf).
3. Connect the FM signal generator sync voltage
output terminals, through a phase shifting network,
to the horizontal input terminals of the scope, as
in Figure 5. (Other values of resistance and capa-
citance may be required, depending upon the scope).
The phasing control should be adjusted to give only
one trace on the scope. NOTE! If the FM gene;--wr
has a built-in phase control, the phase shifting
network is not necessary.
4. Set the bandswitch to the FM position,

tronic vcltmeter, is not as desirable as the re-
ceding method; hut it may he used if_no FM gen-

GENERAL INFORMATION
AM-FM radio chassis HS-230A is the same as chassis ing is connected for use with one speaker instead ol dual
HS~230 except um the euepuz transformer secondary wand- speakers.
SERVICE NOTE
' The following service note applies only to television- be induced into the speaker from the power line because of
radio combinations, where both chassis use the same speak- coupling between the radio and TV chassis. This AC hum
will be noticed even with both the radio and ihe TV power
switches turned off.
One side of the output transformer secondary winding is
grounded in some HS-230A chassis. If the leads tothe
speaker are not correctly polarized, a 60 cycle hum may at the receptacles on the speaker.
