Broken BNC

[eastwood03]

ok so i picked up a bc895xlt and the bnc connecter has been broken off the circut board, i am wondering how do i solder a new back in place, i see there is some of it left sticking up from the diaode, but what i was more wondering about was it being grounded?
any help or tips would be greatly put to use.

Take a photo of that area of the PCB and post it for directions. Should be a simple fix but, I would want to see a photo that I can label and repost with directions.

You should be able to change out that bnc without much problem. The good thing here,is that now you can use a "pro" quality bnc other than the one's that uniden tends to use.
They generally ground to the case,or to a tinned ground on the PCB.

Once you have mounted the new BNC onto the chassis of the radio, the "outer shell" of the BNC should be soldered somwhere on the ground plate indicated in the photo as "Point B". This is PCB Ground. There is usually a ground tab on the connector and if your solderinging equipment can't generate enough heat to flow solder onto that ground plate, then you can use a SHORT piece of wire to solder the BNC's ground tab to a point where that metal plate is soldered to the PCB.

From your photo, it appears that a remnant of copper wire is soldered to the top of an input protection diode. This is where the BNC's center pin would be soldered. Make sure that this connection point (Point "A") does not make contact with PCB Ground. Again... if needed... you can use a SHORT wire lead to make the connection from the BNC's center pin to "Point A".

Use caution is making the connection to the input diode. Too much heat from the solder pencil for too long can cause the diode to crack or become otherwise damaged. If you're not proficient at controlling solder flow; get someone to do it for you.

Good deal, thanks! Its all put together and working like brand new, seems to be a decent radio =)
