It's hard to differentiate whether it's NCD or DPU. If you disconnect the lead in to the NCD this poers down the DPU, but the NCD loses sync with the DPU so stops transmitting. Same if it is disconnected at the DPU end.
I tried ferrites of many types and configurations with no joy.
Unfortunately when using digital modes it is useful to have the internet connection working for logging and the like.
I even set up an antenna in the back corner of the yard and ran coax to it, away from the lead in path. Made exactly zero difference.
The replacement of the aerial lead in did improve things, but once we reduced the interference from my lead in we could then start to see interference from other installations.
