Setup for Range Test

The receiver was placed in the middle of a room, 1 meter above the floor. The room was in the third floor of a building, approximately 8 meters above ground. The windows were closed.
The humidity outside was 48%, temperature was 9.5 °C.
The path between sender and receiver was not completely unobstructed. There were parts of a building in between.

The receiver

The receiver was a Canique MK2 with an integrated RFM69HW 433MHz radio module mounted on a breadboard. Breadboards are not ideal for such tests.
The MK2 was connected to the 5V rail of a Raspberry Pi 3 which was connected to an official Raspberry Pi power supply.
A 0.01 uF capacitor was used on the input of the MK2 - it might well be that the capacitor is not needed at all.
The antenna of the Canique MK2 was a straight vertical wire antenna of 17.3cm length.

The sender

The sender was a Canique MK2 with an integrated RFM69HW 433MHz radio module. It was powered by a single Eneloop battery via a 3.3V Canique Boost.
The battery had a voltage of 1.33V at that time.
The antenna of the Canique MK2 was a straight vertical wire antenna of 17.3cm length.
