Ambitious error message in receive()

[ErikBuer]

I'm working on getting an example of a receiver up and running, and get the following error message:

ERROR: ArgumentError: Signal length must be close to 1ms and above 4ms. Use 8000.0 samples instead.

This comes from the receive() function.

isapprox(signal_duration, 4u"ms"; atol = 1u"μs") && signal_duration >= 4u"ms" || throw(
        ArgumentError(
            "Signal length must be close to 1ms and above 4ms. Use $(ceil(4u"ms" * sampling_freq)) samples instead.",
        ),
    )

The message is a bit ambiguous and could use some clarification.
