Hi all,
There is a bit of misinformation in this thread. The new synthesizer does
not make any difference to the noise floor in the absence of strong nearby
signals. This is how noise floor is usually measured. What it does is
improving the reciprocal mixing of nearby signals and the phase noise on
transmit. This improvement is significant. But the basic sensitivity of the
receiver (noise floor) is not affected.
