While I am asking, is there a way to test diseqc switches without hooking them up to an LNB?
Short answer is nope. I spent most of the day testing DiSEqC and 22khz switches I am taking to the hamfest...I seen one example of a switch that passed power but not signal on a single port...the other ports were fine. I threw away 3 switches that were dead on only one port...one was brand new.
Well my converted multi-switch is still passing 18V out of both H and V ports. Just have to put it on something in between the rain drops to see if signal comes through.
Hope it still works, or I will need to buy the power inserter above, or convert my spare and put it into service.
I'd ask how you converted it, but since I solder with a rosebud and 1/8 inch welding rods, I don't think I'd be a good canidate to perform the surgery.
I am good at blowing them up, however, in fact right now I have a blown up directv 4X8 Zinwell, my latest victim.
I might get a hammer and cold chisel and take it apart and see what it looks like inside...
where would you place this inserter ? at the dish ? i don't have power out at the dishor I will need to buy the power inserter above, or convert my spare and put it into service.

couldn't tell how weather proof the casing was either
Congratulations Fred, you must really like Mav HD & World Fishing Network HD...? You've got to, the way you've fought tooth & nail to get them. I hope you're Happy with it? I know I am! All joking aside, I've enjoyed your efforts on this, as I always do. You have become my favorite teacher, I've learned and continue to learn a lot from you. Keep it coming, I looking forward to your upcoming Mini-Bud project...!!!!
The receiver method you outlined above and the VOM is the way I plan to them for voltage output, but what ACRadio was referring to was signal getting back through. They can pass voltage, but still not allow signal back through and would still be bad.can't you test a diseqc switch that is connected to a receiver by using a coax jumper with one end split with a digital VOM set to dc volts. Having the antenna setup menu scrolling through the diseqc ports and watch the volts jump up when you hit the proper port.
I am thinking you could use a an LED connected to an F connector to verify voltage at a port. It should not harm the diseqc switch since its Milliamp draw would be much less than an lnb.
Just a thought
I discussed a diseqc test procedure with a buddy, earlier this year.
Unfortunately, he got all sidetracked with some mechanical mod to make it small and flat enough to send it in an envelope in the mail.
Of course, in today's troubled times, I don't want to be sending anything with wires and LEDs in an envelope.
The paranoid paramilitary may come after ya.
Anyway, there are four tests:
A - select port 1, is there power on port 1?
B - select port 1, is there power on any other port than port 1?
C - select port 1, is the RF input on port 1 passed to the output?
D - select port 1, is the RF input on any other port passed to the output?
Loop back to test A, and do next port.
We decided to do tests A & B, since tests C & D would be quite difficult without a lot of equipment.
Since each switch input will have 12..18 volts when selected, an LED and current limiting resistor were to be pugged into each connector.
The resistor value would be determined by the current required to see the LED.
Using high-brightness LEDs, ya might be happy with 2 to 5 milliamps.
With regular LEDs, you might want 20 milliamps.
And of course, if you insisted in using this outside, then more brightness might be in order. -
While test A & B would be better than nothing, as ACradio pointed out above, the RF tests would be needed for a proper evaluation.
I thought about building up four F connectors with resistor and LED, but just never got around to it.
