technical considerations:
While I admire the improvements possible in boosting the LNB power output of the receiver . . .
- that puts an increased load on the receiver power supply, which it may or may not be rated for
- it will cause increased heating of the STB, which should be offset by an increase in cooling
- if a receiver has overcurrent protection beyond that supplied by the 315/317 regulator, you may run afoul of it
. . . and more importantly . . .
- the 300 ma power rating of the Ecoda switch was not addressed.
(It doesn't say 300 ma per leg, just 300ma, so one must assume 300ma overall)
I haven't seen a schematic of the Ecoda 22khz switch, so it's quite possible it'll handle 300 ma in both legs simultaneously.
Maybe for those so hell-bent on running two motors, we could come up with a mod that would guarantee 500ma per leg. -
A mod described several years ago, was to the H-H motors themselves.
It revolved around attaching a laptop power supply (source of 19..20 volts) directly to the motor.
It came about because many PCI cards could not drive motors so well.
As a result, the motor drew only around 50..100 ma from the coax for its electronics.
While we are at it, maybe we should find a sturdy diseqc switch.
Or better yet, modify one with bigger transistors and diodes to handle larger loads.
Their diode-switching design may not be conducive to handling large loads.
