Recently, on the Hoosier DMR Network's Facebook page, W9AMT (Tony) wrote that the BaoFeng DM-5R (and Plus) are banned from his repeaters, within a few hours nearly all of the other repeater trustees added their repeaters to the list.

Effectively, they are now banned from the entire network of ~30 repeaters.

Please be advised that I am banning the use of the BaoFeng DM-5R and DM-5R PLUS on all the W9AMT repeaters effectively immediately. If you use one of these, regardless of how it's programmed, it activates both time-slots simultaneously and will wreak havoc on the worldwide network. If you are found to be using one of these radio on my repeaters, there will be no warning, your ID will be blocked, simple as that. I don't want these trashy, uncertified radios used on my repeaters at all. Sorry to be so restrictive on this, but this radio is causing some serious issues and it did not get approval from the DMR association before it was produced. Thank you for your understanding.
For whatever it's worth, even the Rocky Mountain Ham Radio group have published on this problem, and expanded the list to include other similar radios with this issue:

Problems with New Baofeng DM-5R, TYT MD-398 and Radioddity GD-55 Models

Our system users have also asked that no one use this radio. Others can explain it better, but in a nutshell, it keys up both timeslots at the same time. That's a no good of course.

I deliberately bought one (and have since returned it) so that I could do my own testing with it. It failed every test I could reliably validate with the equipment I have available.

I don't know who the first person was that said when you buy junk, what do you expect?
But when you have someone from China designing a radio that will be used anywhere in the world, and doesn't have any rules as per spectrum tolerances, and is given free reign to do as they please, so long as it transmits long enough for the check to clear the bank, what do you expect?

I would compare these handhelds to the amplifiers the CB radio shops sold in the back rooms, where all the buyer cared about was how many watts it produced.
The buyer did not understand anything about bandwidth or spectral purity, the only thing they cared about was being loud!

As long as you have cheap people that are unwilling to spend anything more than the minimum, this is what you are going to get.

Not all Chinese radios are bad. The TYT MD-380 and MD-390 don't have these issues, and they're made in China.

Has Radioddity responded to any of this? They state that this radio is compatible with Motorola. I don't see how it could be. I bought mine to listen only, so this particular problem doesn't concern me. I have yet to get it to decode any DMR transmissions, but I think that is mostly a matter of operator headspace. I have issues with the CTCSS decode falsing and giving spitting noises when trying to monitor analog. I don't think it is a bad radio. It just isn't what it is advertised to be. Radioddity should pull these until, or unless this issue is resolved.

LOL 29.99 dollar DMR radio. yeah I have a feeling corners got cut. Costs as much as a Motorola HT antenna. Wow the MD-398 pushes 10w on UHF?

All my radios are compatible with Motorola's. Of course the Motorola has to be on analog . He never made mention that the radios are "100% DMR tier 2 compliant". It's what you don't hear is what brings the red flags.

Just wait until they dump them off at a closeout dealer. They are gonna have to with all the customer returns and bad reputation.

They'd be ok for simplex.

As an analog radio, they are no different from the ubiquitous UV-5R+ and all of its cousins, aunts, and uncles.

As a DMR radio, it will only communicate simplex with another DM-5R radio. It simply will not work with Motorola, Connect Systems, or TYT (and all of its cousins, aunts, uncles, step-brothers, et cetera). :roll:

I know...I was poking fun at Radiooddity and their "It works with Motorola" which is true...if both the Baofeng and Motorola are only in analog mode

Well, it's been a very long saga, but I finally received my $83.49 refund from SAIN3 (Radioddity). They still owe me the promised return postage. I'm not going to hold my breath waiting on that $7.75! :roll:

However, the refund came unwillingly, since PayPal had to step in and issue a refund from the SAIN3 account after they failed to respond to PayPal's inquiries.

10/23/2016 - requested refund
11/23/2016 - since hearing no response, initiated PayPal dispute
11/25/2016 - received an RMA by email from SAIN3
11/30/2016 - DM-5R mailed to Lenexa, Kansas
12/02/2016 - DM-5R received in Lenexa, Kansas
12/06/2016 - Escalated PayPal Dispute, PayPal sent an inquiry to SAIN3
12/17/2016 - PayPal notified me of refund.

Needless to say, Radioddity will never get any business from me again! :evil:

They are probably trying to figure out what to do with all these returned radios!

Glad you got (most) your money back.

Probably! I'm sure they are taking a bath on these bits of garbage. Ah well, I figure I got at least $7.75 worth of entertainment while I tested the radio on my spectrum analyzer and service monitor! :lol:
