Is there a list of i don't know what to call them "Modifiers"? that you use with your call sign for if your running off Battery generator or your not at your home location's ect?
 

On Field Day ONLY you would be a A station but not during any other time that I am aware of. You must have Three or more operators then. I know of no other times that a Suffix is assigned for battery powered stations.

For general Amateur usage, You can self assign ANY suffix designation that you want to use.


If, you want to ID as "KD2GOE/setup in a park running off battery power", that is perfectly legal.

For FD, you don't HAVE to have 3 (or more) operators, you can operate as KD2GOE 1B NY
(your call) (Class B - Battery One or two person) New York
 
... edit...want to try and work some contests this 22 and 23 we are going to setup in a park running off battery's 1 QRP and 1 50w that i know of right now.

"most" contestors ,(unless the contest actually states otherwise). will frown on things like " /QRP" added to the exchange.

Read the rules for the contest you are interested in and give only the required exchange.

usually something like this: KD2GOE 59 NY

Some of the SOTA type Activations (not a contest) do want the "/QRP" designator.

At most for SOTA I may throw a /P for portable behind my CS, or if operating outside my licence area W7 etc.
 
I'm not a contester but IIRC the "modifier" is not part of the callsign but rather part of the exchange. The alphanumerc sequence signifies power output, type of back up power (battery/generator/solar etc) in addition to number of signals on the bands from the same station at the same time ie multi operator single station or multi operator/multi station etc.

Last years Field Day rules including station classes.
