This is a great and very helpfull website: TYT MD380 Tools

Posted on April 23, 2017 by Daniel

Please have a look at the following Website. As I have been flashing the Retevis RT3 and MD380 for a long time manually now, I still thought this website to be very helpfull.

TYT MD380 Tools

It has a very nice overview of all the features the MD380 hacked Firmware offers. Also the DEVONLY features are very well described. Great job guys!

MINIPA 70

Posted on April 17, 2017 by Daniel

for those who wondered; yes, on E-Bay you get a 70watt shortwave PA for under 30 Euros from China. It’s a kit, and it does not come with building Information, neither does it come with the schema.

All Information you need though you can find on the Blog from PD7MAA. He was so kind to post the schema and some building information.

Have fun building!

Cheers and 73s,

Daniel
