Ryde Receiver sensitivity comparison

[G4WIM]

Hi,

I've been making the final checks on GB3FT before it goes back into service.
I though it'd be interesting to measure and compare the performance of the rx with that of other users.

For bench marking purposes it's operating at 1249MHz 500Ks FEC 1/2 H265 with a Ryde rx.

The duplexer rx loss is 0.7dB and with -112.6dBm input to the duplexer the Ryde reports D 1.3

I have a high confidence in this number as it's exactly the same as it was 8 years ago when FT was first built !
There is zero tx de-sense which is a good thing.
The preamp after the rx duplexer is nothing special as it uses two PGA103's and the noise figure of the two combined is 1.2dB.

I don't think there's much more I can do to improve the rx, but would welcome opinions and comparisons from other users of the ryde rx.
