Display MoreDid you connect like this? Please check for shorts (Kurzschluss) you might have introduced when soldering the F-sockets.
I no longer have the amsat-downconverter, but the SNR was as good as with any other setup i used later. So if your SNR is not what it should be, (/and you connected everything right) there is definetely something kaput.
If you have a lnb with 2 ports, WB should carry 18V and 24/25MHz , NB should carry 14V.

Edit: I can't download the circuit diagram from the amsat wiki, i only get the first and last page, all others in between are blank.
But i have a copy of this on my HD, so if you experience the same, just ask . I will send you a copy. OTOH, there are no levels shown .
No, when connected to the Downconverter, I connected both the NB and WB to the LNBs. I removed the jumper on 14B so that no supply voltage is on the WB port. This works for both the Amsat and the DXpatrol LNB.
There shouldn't be a short - I can measure both supply voltages at the LNB side of the coax (if the 14B jumper is in).
On the wiki there is a level for the 10MHz (0dBm@50Ohm) and 40MHz (3Vpp) references but not for the 25MHz.
What I haven't yet tried is the Amsat LNB with the DXpatrol reference (supposed to be 2Vpp).
