MODing FT-8900R - Increase fm-deviation on 10m

The FT-8900 is a suberb rig, but has quite low transmit fm-deviation on 10m. This however can easily be adjusted in the hidden setup menu.

Just do the following:

   1. switch off the rig

   2. switch it on again, holding the LEFT v/m and the (RIGHT) hyper memory (6) buttons. Release the buttons.

   3. the display now shows "F1 SETMOD RESET"

   4. sequentially push the following buttons: (one after the other) LEFT "low , v/m, hm, scn", then RIGHT "low, v/m, hm, scn" (8 keys in total.!)

   5. the display now shows "A0 menu".

   6. Push RIGHT dial button ca. 2 sec. and release ---> A1 menu is displayed.

   7. Repeat this procedure until A4 menu is displayed.

      A4 is the 10m. deviation menu.!

   8. Turn RIGHT dial button untill DEV.3FH is on display, this is the max. adjustable deviation, ca. 2.8 Khz peak.

   9. Turn rig off.... and turn it on again...THAT'S IT.!

      Good luck with the mod..! (works perfectly with my FT-8900R) But remember, you do it on your own risk..
