[chirp_devel] BTECH IO comments about the patches.

[Jim Unroe]

Pavel,

I only had time to test 2 radios before work, UV-2502 PP and UV-5001.

Windows seems to work fine: DL 33 seconds UL 58-61 seconds

Linux has trouble starting. From a cold start this error is usually received:

Invalid header for block 0x0000:

The debug log is attached.

Usually after the 2nd or 3rd attempt it will start and be fine after that.

UV-5001 DL 33 seconds UL 67 seconds (Windows was faster for a change)


 I will have more time after work to play with the timing.

Jim
