Hi,

D23 is the reverse protection diode and it shorting is the primary reason your fuse blew. As you posted, power was applied in reverse, hence other components would also fail. Pls check:
1. D22 - 9.1V Zener Diode
2. TR23 (2SC1096) 9 Volts regulator
3. D19 - 5.1 Zener Diode
4. IC4 (TA7222) - Audio Amp
5. TR14 (2SC2029B/10) - Finals
6. TR15 (2SC2028B/20) - Driver
7. Most capacitors over 220uF (like C123, C114 & C112)

Hope that this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Hi Zachary
I predict that you have trouble with only one unit.
Try to find some one with either the same units ( on same Frequency of course) or a receiver that also covers same Frequency and transmit on one GMR then the other to esablish which unit is faulty!
The faulty unit should then become apparent, the buzzing could be caused by transmisson of the faulty unit, check all Antenna connections, even change antennas over on testing as prescribed above,
good luck John.

SOURCE: Uniden CXA15198 not showing caller id

Had a similar issue with a brand new DECT2035 uniden phone, displaying incoming call not caller ID.

Checked my old uniden phone, and it was receiving CID. So I connected my DECT2035 to that line and then lo and behold I got my CID.
After further investigation I found that CID on my dect phone wont work if its using a shared filter (ie. adsl/phone splitter). Had to find an unfiltered splitter and then just put a phone filter (that I got with my adsl modem) onto the line that is directly connecting the phone. and then WOOHOO I have caller ID.

Hope this helps you... I got my wife a little cranky over this one cos it took me over an hour and a half to try and sus this one out =)

SOURCE: Red RX/TX and red ANT light on my CB

Well,first hand ,some cobra radio,s have red some have green RX/TX lights, but are you modulating? Some green lights turn red. What is your standing Wave on the antenna,s? You need to check it and the output of the radio. To do this you need a watt or field strenth meter. Can get one at Radio Shack. Your standing Wave is ok as long as it is below a 2. That has to be done on the antenna. ..hope this helps...

Testimonial: "Thx the rx/tx light is supposed to turn red I found out. Still trying to get the antenna prob fixed though."
