RE: NRF52833 BLE Radio Test Issue

It sounds odd that the radio_test example stops at 2405MHz. It should supports all channels from 2400-2480MHz.

1. How does this limit occur?

In terms of other examples you can use the direct test mode example from the SDK:
\nRF5_SDK_17.0.0_9d13099\examples\dtm\direct_test_mode

The advantage of this example is that you can control the device under test from the Direct Test Mode application in nRF Connect, or you can control it from third party test equipment that supports the DTM standard.

2. The SoftDevice controls the frequency directly through the NRF_RADIO->FREQUENCY register.

3. As mentioned above this shouldn't be necessary, the example should support all frequencies in the 2400-2480MHz range.
