New look (M70CM 3.2/P2.0) |
On the other hand, its scanning function wasn't very good, so I was a little disappointed. It sensitivity was also poorer than that of my Baofeng UV-5RE. But at a cost of 34 Euros + VAT, it was OK.
But that was before I found out that its firmware could be updated. I had originally V1.33, 2023-02-10. The images below show it with V1.35 2023-10-20.
Then I updated to M70CM 3.2/P2.0 (PCB version 2.0) and all of a sudden the radio could decode AM and USB modulation, and it came with 8 memory banks for scanning!
Now this is the best scanning receiver I have. It will decode CW on 2 meter, as well as AM on the airband. Thanks to the team of developers behind this firmware!
The radio still lacks some sensitivity though, but I cannot quite see that a firmware update could fix that.
