Foxeer TM25 switcher VTx test power

I made power test of Foxeer switcher, sorry because is an older one (at the moment is new version example)

I dont wire main features because there is a lot information in internet. Main goals is test power outputs on all channels.

To change power you need to hold button when blinks you change power output .

1. 25mW
2. 200mW
3. 600mW

then you switch band
1.
2.
3.
4.
5.

and the least channel
1 to 8ch

Summary:

- as we can see there is a very different power as need to be
- other thing is that at the same channel at the same power ( i mean for example raceband 7 and F8 different power)
 - one as i can write that it works and you will have visual but not as you prefer, too much on 25mW lower at 200mW and even not 300mW on 600mW.

Maybe will have new version so can be compare :) in next will be immersion F because i had one and shipping TBS Pro Race.
