For those who are having problems getting the Testar 12, 15 west high sr like 45000, put a fan over the receiver,turn it up on high and watch the quality go up with a few picture breakups. My belief is that the chip in the receiver overheats only on the high symbol rates and still plays fine on the lower symbol rates.
possible chip problem on some openboxes

mabey the box just has heat problems in general?
I doubt a high symbol rate would cause the box to overheat... it might be causing some kinda glitching/ error... but I doubt the SR is related to the temp.

I'd like to see a picture of the inside of that receiver.
Maybe there's room for a heatsink and fan on the relevant chip.
It's worth a test to find out.

a fan would definitely help the openbox for the high SR, the funny thing is the openbox does not get hot. so far with the portable fan placed over the receiver the quality signal is very stable on 45000 SR freq.
Picture of the S9 Openbox shows that it has a heatsink mounted on a single chip which I would think is the CPU.

Never saw that one, so then it would be interesting to know if they have anything in common, board serial number, date manufactured, software or chip set being used.
