Hello to all

Searching different articles on the net concerning UT5JCW transverters meases(and particularly the 432 to 28 MHz one), did anybody make real gain/Nf meases (principally Nf) of the total Rx conversion with an NGA (Eaton 2075 or HP8970) ? ? ? Because I didn't find ansolutely nothing about ! ! !
And more said, did anybody look at the great meas differences obtained between his 3 versions N-2 (with relay + diode mixer), then N-1 or actual N models (with PIN diode switching) ? ?

UT5JCW says that he measures every transverter before shipping, and that in every case the Nf will be less than 1dB.
I did a complete study on it with an another french ham very known as RF measuring specialist.
So I want anybody to exchange about this important subject (and also for every 50, 70, 144, 22 or 432 MHz family, also via direct mail)

Thank you in advance and 73 to all de Marcel F5DQK

And now more expressively told :
Before buying specifically the 28/432 MHz model (exactly 3 successive generations), have a little look at its RF Tx and Rx measurements posted on !
