HiFER Beacon Project (REBUILD)

Jul 21, 2011 17:43


Not being happy with my current HiFER beacon, it was time to perform a complete rebuild, what follows is the end result.

1. The new case, it is just a standard empty paint can from ACE HARDWARE. The board area is two double sided pcb's soldered to brass standoffs, one side will be the power supply/uC and the other will be for RF.




2. Just another shot of how I have the board mounted to the paint can lid. Thumb screws go into the standoffs to hold it into place.




3. Closer view of how I soldered the standoffs.




4. Power supply section & the PIC micro recycled from previous HiFER builds.




5. Semi-finished RF side.  Ocx, Pre-Amp, Driver, LP Filter




6. I went back in and reworked the LP filter to really knock down the harmonics. (2nd@-46dBm)




Done, adjusted to my desired freq output and Bob's your Uncle. I know this one was quick an dirty, more details may follow.
