I know that the nanoVNA has about 101 (measurement points between the start and stop frequencies. When using it for SWR measurements of an HF antenna, how wide is too wide? Should each band be framed separately? Or is it ok to combine bands to save memory slots? For example, instead of having separate memories for 20, 30, and 40 meters, would I still get a useable reading if I combined them into one memory (start at 7 MHz and stop at 14.35).
Which brings up another question: If I set the start frequency at, say 6.5 MHz and the stop frequency at 7.5, and there are 101 measurement points, that means each point should be 9.9KHz apart. However, the marker moves in 2.5 KHz increments. Is it just implying what the SWR should be at these points?
