MTS2000 ASK Removal

Here are the details for removing the ASK from the final firmware version of 8.73

The ASK Flag can be found in the most significant bit of 0x282. Make sure to update checksum at 0x289. In my case the byte was 80. So it became 00. And the checksum was 14, subtract 80 and it became 94.

I wrote a quick .Net/C# program to take care of the programming for a batch of B5 radios had for $5 a piece on eBay.


Many thanks to Mars and the Python scripts written by Paul Banks.

If I get around to it, I'll publish something on GitHub that finds Block 0x31, reads the existing values and adjusts automatically. Best laid plans I hope to get back around to!
