Hi,

This is not urgent, thinking in advance. As I have the DJ7GP feed

would have to make a new POTY feed etc. for any new LNB such as
bullseye, maybe in the summer.

As for 18v – simply not having 18v available and a spare Bias-T is the
issue. DATV on QO-100 could be interesting…

*Laptop power supplies are about 19 volts. Maybe 20. This may be close
enough, but if not, put a forward biased 1N4004 or two in series with the
power supply output. The diodes should drop about 0.7 volts each.
