+## Sending pictures
 
 The Icom ID-52 lets you receive and transmit pictures either on direct frequencies
 or on reflectors (both need to be digital, just to mention that). I also haven't
 used this either for now.
 
+## Measurements
+
+### Output power on 2m (144 MHz)
+
+Due to my new tinySA ultra I've measured the output power of the ID-52
+<mark>around 145.550 MHz</mark> with the following outcome.
+
+| higher output power settings | lower output power settings |
+| :---: | :---: |
+| ![high output power setting](high-power.png) | ![low output power setting](low-power.png) |
+
+I can only measure 4 traces at once so I had to measure the firth power setting into a
+separate picture (picture 1 trace 1 @ 5 W becomes picture 2 trace 1 @ 120 mW).

 I'd like to add stuff, but time you know... I'd like to add some quotes from
 the manual as well.
