ah.1.11. HW-101-9: Self Oscillations Occurring After Installation of Steel Comb
Brackets
MAY 2, 1975
HW-101 BULLETIN NO: SSB TRANSCEIVER HW-101-9
SEE BULLETIN NO: SB-100-6 DATED MAY 2, 1975 (see Page 153)
ah.1.12. HW-101-10: S-Meter Drift
MARCH 26, 1976
HW-101 BULLETIN NO: SSB TRANSCEIVER HW-101-10
To bring the meter drift to an acceptable level, install the following:
CHANGE: R107 from 100K Ohm 1/2 Watt to 100K 1 Watt [PN 1-28-1]
This makes the voltage divider string more stable with temperature changes caused by
internal heating.
This change will be made in future production runs.
ah.1.13. HW-101-11: Low Receiver Sensitivity
HW-101 BULLETIN NO: SSB TRANSCEIVER HW-101-11
SEE BULLETIN NO. HW-100-7 DATED NOVEMBER 15, 1976
ah.1.14. HW-101-12: Improperly Manufactured 6HS6 Tubes
JANUARY 14, 1977
HW-101 BULLETIN NO: SSB TRANSCEIVER HW-101-12
Some 6HS6 tubes supplied with the HW-101 were improperly manufactured with the
suppressor grid and cathode pin outs interchanged. These tubes will glow brightly
when power is applied.
All of these tubes, with this trouble, have been removed from stock. Any new 6HS6
tubes ordered from parts replacement will be okay.
Some HW-101 kits will temporarily have 6AU6 tubes substituted for the 6HS6 until
production quantities of the good tubes are available.
ah.1.15. HW-101-13: Germanium Diode Change
APRIL 13, 1977
HW-101 BULLETIN NO: SSB TRANSCEIVER HW-101-13
The seven germanium diodes [PN 56-26-1] used in this kit are selected [PN 56-26]
diodes. They are selected for low reverse-current characteristics.
