Hi what you need to do is get the latest firmware from yaesu www.yaesu.com/indexVS.cfm?cmd=DisplayProducts&ProdCatID=102&encProdID=D24F60F33816ED8BE5568D7E2B5E2131 download the firmware and put it on your PC in what ever sub/dir you want then unzip the file then have a look at the PDF which tells you how to update all the firmware i.e. you want DSP it will tell you how to update that to the latest version just make sure if you have a 991 or a 991A I have the 991 so my DSP is up to date. Check on PAGE 5 it tells you how to update the DSP make sure everything else is up to date or you will have to update the MAIN and TFT and the SDP if they are not, Hope this help's. Don't forget 991 or 991A have different Firmware

@@M0AOV thanks the most up-to-date firmware was 2018 all updated thanks again👍🏻👍🏻👍🏻👍🏻👍🏻

@@Massey_Fferguson no problem I just had to update my MAIN and TFT to version 3 and mine was only version 2 so thanks to you also because I had to check the Firmware myself and see if mine was updated

@@M0AOV lol help eachother the radio way
