Yes, Ive done the required calibration. Problem is there are times the needle wont meet the calibration point. Im sure the settings were correct. There are 3 separate settings for 5w, 20w and 200w. I

Thank you for the responses! The issue occurs standalone. I only used NanoVNASaver to get the S1 images for my post in this forum. It is version 0.2.2. You are correct. That is the original version in

Did you see my suggestion in message #12834 about adding a CONFIG-THRESHOLD menu to allow changing the threshold frequency with using a computer terminal? Yes i see but this value need chane once and

Hello, I fully agree. My SAA-V2 is still in transit, but I don't care, as it with today's issues (COVID) sure takes longer. I am sorry to mention another group here, but we already have the

Strange, it possible from high i2c bus speed? I try slowdown it Also set default threshold to 301MHz Try this firmware variant (also after update try 'clearconfig 1234')

Spectrum analyzer plus tracking generator.

I have had no luck with 0.8.4.3 on my H4. The displayed charts are seemingly random and varying on each sweep. When I first connected NanoVNASaver I got an error, see first attached file. Second file

or the jumper from radio to meter

I am afraid you really need a good spectrum analyzer to do this job. And, even with a good piece of test equipment, it is kind of an art to do it properly. Get some help from someone who is

Check the calibration for VSWR on the MFJ first. Check cables. If another (hopefully known good) external meter is available, I'd double check everything. I'll note that I've had to rethink similar

CAUTION: The NANOVNA's do not have the required dynamic range to properly tune a set of duplexers (cans). A properly tuned set of cans, 6 of them in BPBR configuration, will typically exhibit somewhat

To properly use the MJF-872, you need to first set the function switch to "FORWARD". Key the transmitter and adjust the "SENSITIVITY" knob to full scale on the meter (not pinning). Then switch the
