14/18 Volt in Plaza ST-450 and others..... !

[Sathappy]

Plaza uses 14/18 Volt
for polarisation and not for band switching!! Unbelievable!
It's a bug! It's sure 100%!
My system has a 3.1 metre mesh dish, Egis positioner, Chaparral Corotor II,
Ku wideband LNB (LO 9750/10750 and 14/18 volt for band switching), C-band
LNB (LO 5150).

Plaza switches immediately at
18 volt for horizontal polarisation, but LNB goes in high band!

For example: I want perform manual scan on transponder at 11,526 GHz
horizontal at 13 degrees East (swiss transponder); I enter in Channel
Search menu, select transponder, LNB2, mode = manual all.... I tune skew
position and I have strong signal because my LNB is correctly supplied (13
volt, low band); as soon as scanning starts, Plaza switches immediately at
18 volt for horizontal polarisation, but LNB goes in high band!!! And any
channel is found.........
I can't replace my LNB because, as I said, I have
Corotor II for C and Ku band!!!!
The latest software is v. 88

It's hard to digest this problem... because it's a big receiver but now is really small...

It's solved!!!!!
