DOH, you're right, I was looking at chirp's display of the image (hex) 
file and mistook it for the CSV file; once I opened that, the Name field 
was there, waving it's little paw at me.

Where in UV-3R's file is this stored? And, similarly, where do they 
store the BCLO (xmt lock-out while channel in use) flag by channel?

It appears to me that Baofeng/Vero is using offsets (bytes) 04 and 09 in 
each 16-byte frequency (or channel structure) word to designate the 
CTCSS tone or DCS code. From what I see, there are 50 CTCSS tone codes 
and 104 DCS codes. Do I double that last number to account for the 2 
polarities? If so, that means I'm trying to store 258 distinct bit codes 
in a max 16-bit hex byte (00-FF)..

In the words of the MC at the melodrama, we have 6 beautiful girls and 4 
lovely costumes.

  Is what you classify as DTCS "R" polarity what the Baofeng folks 
designate as "I"?

Thanks and 73 de KK4DBR Ron
