Reception location, approx?
North Somerset.
Signal level of 48-57 isn't imho sufficient for a -T2 (or at least not my one)
It's fine down to about 30, IME.
Trees and lack of line of sight won't have helped.
I am partially obstructed by a ridge 2-3 miles away and the consequent diffraction loss, but it's been OK for the last 14 years (apart from
this incident - post #5).
In the analogue days I was on a relay, but wanted digital 2-3 years before DSO hence the change, and in those days the powers were lower than they are now. The relay is of course no use for the COMs.
I'm wondering if a log periodic (which one there are many?) is sufficient for your location (external/loft/?)?
I've no idea of the make. It is external and sufficient. If it was in the loft I'd be all over it, but a) aerials should generally be outside and b) it's right at the top of the ridge where I have no desire to go, even if I had a ladder long enough, which I don't.
The weather currently (Sunday 24th) isn't particularly conducive to enhanced propagation (and hence CCI) unless your predictions are poor on the detailed view of the Freeview tool.
They are 99 or 100 mostly, with one 98. Now, something else comes back to me which I parked a few months ago due to lack of time. PSB3 from Wenvoe on 47 isn't working either and it used to. Everything else from there works, although it can be a bit iffy as it's off the side of the aerial.
And back to a couple of years ago in the middle of C**** everything became a bit unreliable and I stuck in a low gain masthead amp. to improve things which had become marginal. This is now getting a bit suspicious - I wonder if the cowboy has b*ggered the aerial, the connection, or the cable in to the loft from it (which was the only bit replaced in the previous incident).
Local muxes are more robustly coded (with lower data payload as a result) so lower S level works for them.
I know, but coding doesn't affect the strength figure, only the ability to demodulate/decode.
