This complete, tested FM828 internal power supply/Audio PA 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 - Power Supply & Audio PA Module
Type: FM828 Transceiver Series
Part # 309 92570
Brief functions:
Audio power amplifier (TDA2002 in a pentawat package)
Reverse Polarity protection
RF power control
10V DC regulator
PTT circuit
Transmit limit timer
Removed from a multi-channel FM828 A band transceiver
Dimensions: 144mm x 67mm x 15mm
Weight: 100g
Supplied with the original 5x chassis bolts.
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 (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.
TESTING:
Immediately prior to carefully dismantling the FM828, I set it up to test this and other FM828 VHF TX/RX modules and everything is working fine - correct voltages from this module and the relay is operating fine.
I have now packed this board into sealed plastic to protect it from the environment.
So there you have it, another PCB module from the old FM828 series transceivers which might be exactly what you need!
