Port Codeplug Tytera (TYT) MD-380 to CS-700

The Tytera (TYT) MD-380 software is close to the CS-700 software, except it will not read the CS-700 codeplug, and vice versa.  You can hex edit it, and make it work. When the actual radio shows up, I'll let you know.

The software is NOT identical. They are close, and based on the same code, but they are not identical.  The MD380 has features that the CS700 does not, so the software is different.

The scan on the MD380 is a bit slow, but the nuisance delete does work. And it scan multiple channels.

But if you're looking for scanner speed, you'll be disappointed. The receiver on the MD380 is quit good.

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.

HEX Editor Codeplug CS700 converted to MD380

I have a codeplug for a CS700 that I have converted to MD380 (Since that is what I own). The issue I have is that when I load it into the CPS, it shows that its for a VHF radio, when it is actually UHF. I am unable to change this without clearing all the programming. I know that with hex editor you can fix the value to make sure it displays as UHF. Can anyone help me with this?

The following hex compare shows the differences and locations in the files. I haven't actually tried manipulating these values, but I'm pretty sure that CPS is reading and writing to these locations:

E:\temp>fc /b vhf.rdt uhf.rdt
Comparing files vhf.rdt and UHF.RDT
