In that picture it looks like the RF gain pot has not been adjusted yet. There is a range on it where it acts almost like a short to ground. To tune the knob to max you need to find an active signal and adjust it. Please do this next. Even if you think you have please do it again. The adjustment can be very finicky.

Jack your the only one who seems to have had a real issue with this. I can assure the the schematic is harder then the drawings we gave. I Know I screwed the first drawing UP! If your having issues with your unit please start a thread instead of derailing someone else's with your griping. The schematic for the OG circuit is available on ND6T's site. The only changes we have made are adding a 5v regulator, and wiring a switch up to pick a different time constant resistor. If your so confident that you can understand the schematic, Then good the part that relates to the switch is inside the instructions zip WITH indications as to what pads are what. If you can not seem to find them in the zip, Kelly here has posted them in the OP on this thread. The second picture has the correct wire up schematic for the switch.
