Anyone have schematics on the Mongoose 450 / Rebel TX500 / Blackhawk 120 (Same radio)
PC Board Number is: jpmxx0222-a
Picked up two of these little gems on Ebay last week for $15 each. One works perfectly, the other one receives but does not transmit. Been going back and forth between the working one and the non-working checking voltages. The only reference I've found so far is a block diagram over at the tricky cb site.
Found a difference in voltage on Q18 (RF Amp) but without a schematic or a voltage chart, I'm working blind.
I guess the good thing is I can hear myself on a nearby radio, but am showing no wattage out... gotta be something small, blown cap, diode, transistor, etc somewhere in that transmit chain.
Thanks in advance for any help.
