[chirp_users] ? re 'duplex' field

[Benton Holzwarth]

I'm helping organize a base set of frequencies -- a 'standard load' -- 
for our local CERT group, Tigard, OR.  I've read a ton of posts and come 
up with a base set of guidelines that I'm hoping will cover the 'least 
common denominator' radio that someone might show up with.

   o Don't use row zero, some radios start at row-1
   o Hold to 5 characters for the memory 'name'
   o Include the FRS and official frequencies as Rx only
   o Different radios have different numbers of memories, pack the 
highest priority bits into the lowest memory-rows.  Some radios stop at 
16 memory-rows, others go to 100 or 128

We'd like to load some Rx-only frequencies -- FRS, the local police 
forces and ambulance service that use UHF, but in Rx-only.  When I set 
'duplex' to 'off' Chirp says something about not all radios support this 
setting.

   o Is there a list of radios that do support?
   o If I try to program duplex-off into a radio that doesn't support 
it, what is the reaction from Chirp?  Does it let me know there's a 
problem or just gloss over and make those frequencies tx-able?

I'm trying to figure out how best -- across a wide field of radios -- to 
manage a set of frequencies that should be Rx-only.  Duplex 
off/split/offset  One solution seems to be to dial in 'split' pointing 
the tx-side to a harmless corner of the Amateur band.

Thought?
