I started this a long time ago and finally got around to finishing it up tonight I used a Z1000B Buffer Amp from Clifton Labs from the K3 feeding into a SoftRock Lite II Combined Receiver Kit The output from the Softrock is then isolated with a a couple of audio transformers form a Sound Card Interface (I cut the interface board down and I'm only using just the audio transformers). This in turn feeds into my sound-card on my PC that is running the NaP3 Software Note: The 1/8 jack is isolated from the case by drilling the hole large and using an insulated washer. I used my RigExpert AA-170 and an Oscilloscope to sweep the transformers to ensure they were good up to 200 kHz That way I knew they would work up to 192 kHz wide on my sound card. (I had some other transformers that rolled off too soon and would not give the desired width.) |
