• Changes to the AM Analog board (OST-3A128) to improve performance

ECO #547.
C37 was 220nF is now 100nF and C40 was 8.2pF is now not installed
C45 was 33nF is now 22nF and C49 was 2.2nF is now 1.5nF
R32 was 33k

Ω

 is now 56k

• Changes to the AM Analog board to improve performance at  -40˚C.

ECO #565.
L4 was 1.5µH is now 3.9 µH

• Changes to the FM Analog boards to improve manufacturing. ECO #572

C32 & C33 were 100µF through hole tantalums  are now 100µF surface
mount tantalums

• Changes to the OS-3A/H Digital board for compatibility with the new AM

wideband Synthesizers. ECO #579.
Added C15 (10µF) and R41 (221k

Ω

).

JU1 was added and is installed for AM modules only.
PCB, DIGITAL, OS-3H/P SYNTH was version 2 now version 3.

• Added the new component layouts, schematic diagram and parts lists for

the new AM wideband synthesizer. Wideband referring to only having to
be tune once and working over the whole AM band (118-138 MHz).
