[Moon] 3cm TWT standby Noise in RX

[Walter Crauwels ON4BCB]

Hi all


I was wondering if somebody has some experiance with noise comming from
TWT's (YH1127/1136)  in RX or standby using a 2 port WG septum feed (OM6AA)
on 3cm

In RX the output of the TWT is permanently on one port of the septum

I'm investigating if it is needed to switch the output of the TWT
(YH1127/1136) to a load in RX and  in Standby



Looking forward for your comments
