This complete, tested FM828 internal Multichannel Oscillator board has been carefully removed from an A type FM828 transceiver.
The module being offered has not been modified
I have other FM828 series components, boards etc HERE - time to do some experimentation with this nice old analog communications technology!
PHILIPS - Multichannel Oscillator PCB
Type: FM828 Transceiver Series (A & B Bands only)
Part # 309 90691
Brief functions:
Expands the transceiver's possible number of crystal locked TX/RX channels from 3 up to 10 channels (3 channels being on the main RX or TX board)
Removed from a multi-channel FM828 A band transceiver
Dimensions: 68mm x 70mm x 17mm
Weight: 100g
Nicely engineered (the old fashioned way using single sided PCB, discrete components, no SMD) and numerious (identified) PCB pins for external connections.
Plenty of manuals, discussion forums online talk about the FM828 and upgrading an existing FM828 to multi-channel use (after almost 50 years these things just keep on going!)
COSMETIC CONDITION:
PCB is clean and it doesn't appear to have been 'worked on'
All interconnections have been removed (from PCB pins), Philips have numbered all the PCB pins and reference to the circuit diagram/board layout will easily show just what goes where.
The board comprises two separate sections, transmit with 7 crystal sockets and associated tuning components and receive, again with 7 crystal sockets etc ...
Just in case they are needed, the original 2x mounting bolts and bushes are included.
TESTING:
Immediately prior to carefully dismantling the FM828, I set up the board with an FM828 A band transceiver and everything was working fine.
I have now packed this board into sealed plastic to protect it from the environment.
Another PCB module from the old FM828 series transceivers which might be exactly what you need!
