I found this reg hack here on these forums 5-6 months ago. It was one of those little gems that I threw into a text file for later use. I have used it on a couple of Touch and Mogul PPCs, each time successfully. If I remembered who the OP was, I would give them credit here and now. But since I do not, I will simply state that it is not my work and thanks again to whoever was the OP.

--- BEGIN REG HACK ---

Change the following registry entries in:
HKEY_LOCAL_MACHINE\SOFTWARE\HTC\ATDbgLog
Enable: 1
LogMode: 1
* Wait a reasonable amount of time and soft-reset (I have noticed that it seems to take longer for this value to take affect, so if you reboot and the registry values are not changed, then you need to do it again and wait longer)
* Check to see that the file \Temp\ATDbg0.txt has been created.
* Return the values back to what they were (most likely 0) waiting the same amount of time as above.
* Look in the ATDbg0.txt file and you should see a log of commands sent to the CDMA radio and there should be something like this somewhere in the file:
|| Begin Code Sample ||
11:9:3 Tx:AT+HTC_RMSL=0\r
11:9:3 Rx:+HTC_RMSL: 354201\r\n0\r
11:9:3 Tx:AT+HTC_ROTKSL=0\r
11:9:3 Rx:+HTC_ROTKSL: 216112\r\n0\r
|| End Code Sample ||
The numbers next to the Rx: +HTC_RMSL line should be your MSL... I do not know what the ROTKSL is for, but included it in the snippet incase someone knows.

--- END REG HACK ---

Give it a try, it should work flawlessly for you...
