Here are a few photos showing the procedure to install the optional filters, TXCO-9 and internal batteries to the Yaesu FT-897 rig. There's nothing hard about installing any of these modifications. The instructions in the Yaesu manual are fairly comprehensive and the menu options to select them are easy to get right.
Make sure to get the filters and TXCO-9 round the right way. It's worth noting that the actual filters are labeled with different part numbers than on the boxes! The YF-122S is marked XF-119SN and the YF-122C is marked XF-119C. Please email me if you have any questions or comments. Click on any of the pictures to see it in full detail.
