Therefore the universal lnb will not be able to select hi-band frequencies while the meter is in line.
So I'm not sure that those spec sheets are telling it like it really is, unless I have an older model?
Note: The 22Khz tone universal band switching tone is about a 1 volt ripple imposed on the DC V/H supply.
Can someone please check and confirm.

Just out of curiosity, I connected my oscilloscope between one of my receivers and an lnbf on a fixed dish, but used the receiver to send 22KHz Universal lnb type signals, as well as the DISEQC east/west motor commands, ( even though there was no motor there to receive them). I was able to see these on either side of the
SF95 signal meter. My scope isn't calibrated in any way, but I was seeing about 0.7 or 0.8 volts whether on the receiver side or the LNB side of the meter. Of course, my tests were done in the house, some 250' away from the dish, so there may have been a different reading if I had done the tests out at the dish near the lnb.
Anyway, I'm not sure what I am doing differently. It makes me wonder if there are different versions of these meters? I've seen different pictures of these meters on the webs, which are all relatively the same shape and size, but look slightly different relative to the appearance of the plastic, ie smooth vs rough surface. I'm using the meter purchased from
Sadoun, and looks like those pictured on the Sadoun web page.
