Check my portable bag for Yaesu radios (FT-817, FT-857). Bag has three main sections. On the right section for an antenna analyzer or antenna tuner (has a waterproof case). On the left side you can store cables, headsets, headphones, interfaces, etc.
The central part of the bag has two sections. One for the transceiver and second for a battery. Also, the bag has several pockets where you can store documents, instructions and manual.
The cover has several pockets and they are all waterproof. The upper pocket can be used for a netbook or ipad.
Bag can be used as a backpack, this is an additional straps.
