I am a new Ham. I received my callsign in January with Technician class privileges and passed the test for the General class in May. I bought a used BF DM 1801 back in February. I was having issues with the code plug programming. Coincidentally the day I got the firmware updated to OpenGD77 the battery died. I could not get the battery to take a charge, so I ended up having to order a new battery and charger base. I believe the radio had been disassembled because the brass nut securing the antenna terminal was loose in the box. I could be wrong, but there seems to be a short in the speaker. I have a few local repeaters programmed with their corresponding talk groups. I have not been able to determine if the lack of sound is due to my code plug or my speaker. Anyhow, this seems like the place to be for help in figuring these problems out. This has been frustrating at times, but overall I am enjoying the challenge. I like to look at it like solving a puzzle. Looking forward to meeting some of you who are also working with this radio.

Welcome

Its possible the nut just worked loose, as I don't think these radios get any form of quality control in the factory, but as the battery was also defective, it sounds like they sold you a radio that someone else has returned

It turned out that the battery was fine. It was the charger base that was the problem.

You could try a headphone in the remote speaker mic jack... It might help you determine if the radio has any audio.

I think that these radios do get some form of testing an quality control, plus much of the assembly is likely fixture based and to some extent automated.

There isn't much budget for doing quality control, though.

In case you'd like to review it, there have been videos made at the factory. This post links to many:
