Head to head tuner test

[Analoguesat]

Thanks to my over elaborate coax system from the dishes Ive managed to do a head to head test between the tuners on the 7020 and the Duo.

Both are connected to the same lnb on the same dish, via 2 separate coax runs, and are tuned to the same frequency.

The screen caps are taken a few seconds apart on a weak APTN feed on 10.

The Duo is the one holding up better.

From this I conclude that the Duo tuner is slightly more sensitive than the 7020

If you swapped over the coaxes and again got the same results then I would agree with you

Hmm. That's only at one frequency, though.

To do a rigorous comparison you'd need to sample a fair number of frequencies.

There is your task for tonight.

I, however, am watching Last Night Of The Poms.

Is that the Aussie version

Might do that - Ive got a spare A/B switch lying around, but thats a game for another night when Im not so tired. Pulling the cabling apart on the satellite receivers on a Saturday evening is a sure fire way of making me very grumpy

tuner of early dreamboxes Is known to have problems with low symbol rates though the second shot (duo) has pixelisation too
can you do test on 4.8 E 12.092V, 12.476V
