Re: uBitx relay pinouts
Figured it out. I have been running my uBitx with KD8CEC's firmware and have been particularly happy with his SDR adaptation. However, it really bugged me that I could only see a very small amount of

Re: ND6T AGC implementation for uBIT-X
If you're only looking at reflected power and it's flat you don't know if you have a good swr or the radio isn't putting out. Now if you're also looking at forward power, the mystery is solved. Vince.

Re: Coding styles
Braces or brackets? Braces mark statement/function blocks while brackets are most often used with array sizes. The old K&R style was to leave the opening brace on the same line as the expression

Re: ND6T AGC implementation for uBIT-X
So what would be the minimum compute requirement on an existing Nano ? Maybe read 2 analog inputs directly from 2 AD8307s? with only a scaling factor for Stockton Bridge coupler loss. Multiply that

Re: ND6T AGC implementation for uBIT-X
I guess then to take it a step further, all you need is the reverse line section, a diode, a couple of RF blocking capacitors, a resistor, and an LED. LED blinks when there is reverse power. You could

Re: ND6T AGC implementation for uBIT-X
A simple measure of reverse power will tell you if the antenna is working ok. Forward power, and using it to calculate SWR, tells you more about how your rig is operating then about the match to the

Data sheets specify "viewed from below", usual convention is to view from above. In between comes mirror-imaging horizontally and vertically. It's a mess. Definitively, with device in hand, view as if
