Re: GPS usb port not working
Alright, I guess it helps to go back and read directions and also look at pictures of what you are doing. Anyhow, found I had mounted usb on wrong side of board and removing it was bit tedious with

Re: QMX Capacitor Swap Gives Lower Power. #qmx
Bob, Very similar to my experience. At present 30M is 1 watt lower than before and 20M about 1/2 watt lower. The only difference here is that both caps are installed in the normal manner on from the

Re: QMX Capacitor Swap Gives Lower Power. #qmx
Um....here's a bit about my results: - BEFORE the swap 30M was putting out more than 1 watt higher power than 80M, 60M, and 40M ...? PLUS 20M was a 1/2 watt lower than 80M, 40M, and 60M. (And this

Re: QMX LTSpice BPF filter plots
Yes, Steve. Your comments, along with my study of the Softrock Ensemble RX, and a little bit of LTSpice simulation have pretty well convinced me that your point of view is correct. The detector

Re: QMX LTSpice BPF filter plots
John, It's a difficult subject and I appreciate all your thoughts on the topic. But this last reply seems yo indicate the series LC bandpass filter sees a load impedance of 22-25 ohms, not high

Re: GPS usb port not working
After looking at circuit board closer, I am beginning to think I may have mounted usb on wrong side of board. It is on bottom of board and not on the side with component traces. Anyhow I guess I can

Re: QMX LTSpice BPF filter plots
Alan, I think those resistors serve multiple purposes: Since the system bandwidth is controlled by the resistance in the capacitors charging path, having some stable, fixed resistance will

Re: QMX LTSpice BPF filter plots
John, From Mr Tayloe's Pacificon presentation - See attached. The quadrature detector assumes a 50 ohm driving impedance. I took a look at the schematic - It's a standard bandpass filter like one in
