14 Jan 17:30 Problems with Channel C or D Stop the experiment

[avaldez]

1) We make a change between hybrid 1 (ChA&CHB) and 2(ChC&ChD) to identify it's the problem is the hybryd or something else. If we don't see a swap in Cross-Spectra graphics the hybrid is not the problem. So, after the change hybrid we don't see any swap in the cross-spectra graphics. Then the hybrid are ok. We did the same test changing channel A&B with C&D in th input of T/R after the change we notice that the ghraphics swap , so that means that the problem is outside, also we did the probe in the amplifier channel changing the same position getting the same resulta, so the conclusion I think There is a problem in the compensation device or in the antennas, please comment if something is not clear.

18:30 THe experiment continue.
