I am interested in buying a schematic diagram for the Uniden MR8100

you can do a search for the MR8100 and get it off of the web.

I have tried many google searches and have not been able to locate the schematic. All I can find is the operations manual which I already have. If you know where to locate it I would appreciate the help. Thanks

I will look for you...

is there a problem with the one you have?

The power leads got accidently shorted. I have been able to repair the circuit board and have replaced a few diodes so it now scans again but I can't get any audio. I need the schematic to try and figure out where to go next. I ordered a service manual from Uniden ($32.95), it got lost in the mail so I don't know if it will help. Uniden is suppose to be sending me another manual.

ok, I have a bunch of them and I am quite familiar with the MR-8100, if you need one for parts I do have one available, did you check your audio amp with a scope or the speaker leads? What you can do if you have a service monitor is put the scanner on a frequency, generate a signal to the scanner and take a scope and checkout the the audio amp, if you see the wave on the input pin of the amp and nothing out then you have a bad audio amp... Also is your scanner recieving a signal?

I have 2 here one is opened and for parts the other one powers up and has audio but needs to be opened and tuned, were you interested in any of these?

How much are you asking for the one that can be used for parts? If the price is right I might be interested in both. Thanks for your help. I received a service manual from Uniden yesterday.

the one that is for parts only I would take 25.00, I will take 50 for the other one....
