I purchased a surplus remote repeater (turns Infa-red remote signals into rf, and broadcasts it to a receiver) that works rather well, but the IR receivers capability to receive is raher lethargic. Unless the remote control is quite close to the IR receiver it doesnt work...move a foot away, and it doesnt receive it at all. Is there a simple preamp circuit that I can place in between the detector and the transmitter circuit.
I have tried replacing the IR photodiode with one that is supposidly more sensitive, with limited success.
Thanks in advance
