1&2&3GHz Transverter modifications

Adi, S55M had crazy weekend…

We already reported that bands 1, 2 and 3 GHz will be operated from one station (Op. S57C), so switching the transverters is crucial at this point. He synchronized all three TX relays. All transverters have PA circulators at the output stage, so everything coming back from 3-band feed is terminated with resistors and we have no signal on RX transistors. Next modification he did was putting the TCXO G8ACE in 3GHz transverter.

Necessary measurement was also the frequency shift on IC275E which will be used as main station on these three bands.

More or less that would be all for 1, 2 and 3GHz setup. We all hope everything will work fine :-) 

Below are the photos Adi took during his work…
