Hello everyone, I just picked up two of these radios and want to reprogram them. The only programming cable I can find for them costs $40 which isn't worth it to me, so I want to make my own.
I found this this website which includes a schematic for building a programming cable. It seems fairly easy, but I need some help figuring it out as there are a few areas I don't quite understand.
Here's the schematic in question:
Here's what I need to know:
The guy at the website I linked to used 2 50V,.01uF, Ceramic Disc Caps but I don't see those in the schematic anywhere. He says to use a +5.0V 1.0A TO-220 Voltage Regulator so you can use a 12v power supply, is that where the disc caps come into play? If so, how do I hook them up?
Also, where does everything need to be grounded to? The power supply ground?
Thanks for any help.
