That's not finicky, it's sensitivity.
Humax tuners seem to be a bit more sensitive and a really large signal will overload them (as it will with any tuner if the signal is high enough).
This distorts the signal and screws up the demodulator which promptly gives up the battle of error vc0orrection. This manifests itself as 'no signal' report with the obviously accompanying 0% quality.
This signal variation can vary with the time of day and especially weather and atmospheric conditions.
If this is the case (which it sounds like) a fix can be achieved by the somewhat counterintuitive principle of reducing the signal level from the antenna by using an attenuator as suggested above.
However as 105 & 106 are likely on a lower power Mpx, this seems unlikely, but if the attenuator works for you, jolly good.
