MD-380 motorboat sound

When I transmit with a MD-380 and a rubber-duck antenna, there is a "motorboat" sound on my transmit audio when using a Retelvis speaker mic.  I opened the mic and observed that they are not using a shielded mic cable.  When I transmit into a dummy load or an outside antenna the "motorboat" sound is gone.

Has anyone been able to fix this RF into audio problem and what speaker microphones do not have this problem?

The problem goes away when you use the proper mic for it... such as the following unit.

Capacity Plus Scanning with Experimental MD-380 Firmware

Capacity Plus Scanning with Experimental MD-380 Firmware

Scanning a 4 channel Capacity Plus system with a MD-380. This was with the experimental software that allows the radio to listen to any DMR traffic heard. I have set up one channel as a scan channel.




Best starter DMR radio?

Looking at a few different options you could choose from as a first DMR radio. There are also the Hytera and the CS-750 radios which are meant to be good, but I didn't include them in this video because I don't have any personal experience of them.
