    Hello Family

    I am very sad.....

    The last year, in september I bought a Baojie BJ-218
    Serial Number: 1718BJ4196

    And today when I push PTT on mic, TX appears on screen but not power ... Dialy I was used the radio to activate a FM repeater near to my home, and today no power from radio baojie . I try to monitor with my handheld but not signal received from baojie

    And when remove the cover I find a burned hole ... I don´t know wich component are there .. ???

    Did you contact the manufacturer for a service manual?

    I didn't quickly find one, but did find a service manual for a different BaoJie model: http://www.qzbaojie.com/home/6/5/zwyp75/resource/2017/01/20/5881c988d7ba6.pdf so at least that seems to indicate they do create the manuals.

    I don't think these are sold in the U.S., but do see we can buy them directly from the factory in China for $USD 72.00 brand new, so it's a pretty inexpensive radio: https://www.banggood.com/BaoJie-BJ-...nge-p-1141667.html?stayold=1&cur_warehouse=CN

    The Baojie BJ-218 transceiver recently purchased new, is not sensitive. An FM signal that I receive with a Yaesu transceiver S7 , with this TRX, bringing the squelch to 0, does not exceed the background noise. Is this normal or this equipment is defective?
    Thanks to those who will answer me.
    Friendly 73s.

    Hello.

    I have a similar issue with Baojie BJ-218, Mini-218-R-25W Rev:4. There is no output power on UHF. I checked some capacitors and I found various shorcutted. They are marked as red. Does anyone know what value they have? I sent a message to Baojie asking for Service Manual with no response until now. Baojie BJ-218 Fail.jpg
