Hi,
Pretty much first time posting here but I know the is probably the best place to pose this question!
I picked up this little gadget the other day and have spend a good many hours when I should be revising to try and work out what it does. It is in a perspex box labelled "Super Baby J" and features two female F connectors on it (joined together on the PCB) and a power supply input (with bridge rectifier and 7805 regulator on pcb.
There is a IR receiver coupled to a PIC 16f84 microprocessor, which is itself coupled to a LM7000 PLL synth IC which is a key component in radio tuning circuits but is not a tuner in itself, the datasheet for it leaves me dazed and confused.
There are some passives and a few transistors associated with the LM7000 which also has a trace running to both the F type terminals.
The PIC has its crystal and stabaliser capacitors fitted.
Any Ideas, I am thinking along the lines of something which shifts frequency, maybe for using foreign radios in the UK or similar? I can only see it putting something on the RF bus, I figure it would of had a remote for controlling it.
Google is no help on looking up Baby J....
Pics are attached!
