SB-101                                          Bulletin No:
SSB Transceiver                                 SB-101-1
                                  Meter Zeroing

Original 10-147 control tolerance not sufficientto allow zeroing in all
units.  This part is being respecified to a closer tolerance.  In the
meantime, any field problems requarding zeroing of the meter can be
corrected as follows:

Change:   R-107 from 100K Ohm to 82K Ohm (1-159).
