ah.1.41. HW-101-37: R-940 Shorting To Shield
OCTOBER 11, 1978
HW-101 BULLETIN NO: SSB TRANSCEIVER HW-101-37
To prevent the leads of R-940 shorting to ground, install a length of sleeving [PN 346-1]
on each lead of R-940.
This will be incorporated in future production.
ah.1.42. HW-101-38: Poor Carrier Suppression
OCTOBER 13, 1978
HW-101 BULLETIN NO: SSB TRANSCEIVER HW-101-38
The HW-101 carrier suppression specification is -45db or below. If the carrier cannot be
nulled on both USB and LSB to this level, try changing R9 on the modulator board from
a 1K Ohm to a 390 Ohm [PN 1-48].
This change will reduce the injection level to the balanced modulator and hence reduce
the carrier suppression level.
