Extra Modifications to the filter system for GB3TS

Extra Modifications to the filter system for GB3TS



We got a lot of work done on site last week.
Cabinet installed by Ian G7MFN with all the trimmings ( PDU power distribution unit and shelf) and after a spruce up we done a few tests which revealed that the cavity filters even though they were perfectly tuned were showing a high SWR.
The antenna has a perfect SWR of 1:0 (one to none as they say but as noted i should realy say 1:1 ) so we will be going back up next week after the new N connectors arrive and I have soldered them into the the RX filters. This time we will try to notch at the RX side so there won't be a swr problem.
