Re: AWM1361 IC data?
I have the service manual for it - every other part is marked in normal consumer codes. This is the one and only 'special' part in the whole radio (discounting the phenomenally small and cute tapped toroids in the RF sections!), so I suspect it was specially manufactured in order to produce the dual downwards swept tone bursts and the beacon Tx switching.
I have a SARBE-6 (BE515) working and modified to disable any Tx, but dont have the schematics for it (worked the switching scheme out based on the SARBE-5 and lots of testing with a multimeter!), not sure if it uses the same IC. I have the SARBE-5 on its way to me from Italy.
Since the mods to disable Tx effectively make this IC redundant, and its on its own little plug in board (I think, might be some other circuits on there), I might remove it to play with. Possibly freeing up some space for an RF pre-amp to improve the receiver.
