Hi Nev,
it does sound like you have a real teaser there with that problem, I had thought it was a case of mast head overload but seems not to be the case if the filter is ahead of the masthead, it should be peeling down the signal from the 2 metre band quite well. I know it may be difficult but is it possible to test reception without the mast head inline? hoping there is enough signal there to give you some signal lock on DTV as when you say it happens all across the 2mx band it screams at me it is mast head overload but hey I am not the one on the ground trying to fix it so sorry if I sound like a one track record
Yes good idea on the braid breaker, it may be some common mode currents that are causing the TV to hiccup in the presence of the WSPR Tx.
best of luck in your investigations, sorry you did not get the same benefit as I did from the filter.
