Yaesu FT-8900R

Low 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. 

Switch off the rig

Switch it on again while holding the LEFT V/M and the (RIGHT) hyper memory (6) buttons. Release the buttons.

The display now shows "F1 SETMOD RESET"

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

The display now shows "A0 menu".

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

Repeat this procedure until A4 menu is displayed. This is the 10m deviation setting.

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

Turn rig off.... and turn it on again.

Done!
