Impressions of preparations for 38c3: Our setup for validating the rx frequency of the RF-Board via DIO2 pin+ using a loosely coupled frequency generator and an ocilloscope.

Pager prototype connected to the oscilloscope probe with two wiresOscilloscope displaying a quite uniform high frequency waveFrequency generator: a grey box with square buttons, a round dial, and a display showing the following values:
