There is a guy on ebay thats selling an Apx4000 he claims is modded for ham use and that he will send a drive with the radio with the mod. I know this is an old discussion but I havent seen any mention of a mod anywhere else yet> https://www.ebay.com/itm/196555920218?mkcid=16&mkevt=1&mkrid=7...

Wondering if anyone has had any success with this yet? There are a lot of
these radios floating around and it would be nice to get them in the ham band
as there not to many decent choices for radios for 220.
