I recently bought an IC-F3021S radio off of ebay with Revision 1.0 and was wondering if I upgrade the firmware, will it disable wideband use for 2m? It currently does wideband without any problems and I have read on some sites that upgrading the firmware will lock it to narrowband only. If that is the case I will leave it alone but I would like to get the last firmware update as I also use it in a commercial environment. Also do you have to pay for the firmware just like you do for the programming software? Please don't laugh at the question because this is my first commercial radio I have purchased so I really don't know. I bought the software so I wouldn't mind paying for the firmware, I'm just curious if that is up to the dealers to charge for the updates. I'm not new to the ham world or using radios, just new to owning a commercial radio.
