Is it more or less of a good time, than the nanoVNA and the tinySA I already have provide? Of course, not that I am suggesting there's a limit on how much of a good time you can have.

Need to swr the antenna in
and I forget which way to go about it
LOL
NanoVNA needs a revisit for operating instrutions
might have a nap first

The idea is to fill the gap between a cheap and fiddly nanovna (not practical in the field) and a nice (but expensive) rigexpert.

Finally back to #timenuts stuff! GNSS distribution amplifier seems to be working as designed. S11 seems much higher than expected at only around -5 to -10dB. The filter is meant to be internally matched, as is the amplifier stage so not sure what is going on […]

First (easy) test of the QB-150 Amps: Does the one with the top installed work? Answer: Yes! Measured 12.6 K Ohm on the power pin to GND. Applied 12.2VDC, measured ~120 mA current draw. Tested with NanoVNA-H4 with 40 dB pad on input side and found it has ~ +24 […]

Oh no… I did a new thing, and it worked, and now I have IDEAS! 😂 I made my first antenna today, a simple vertical dipole for the 2m band. It’s literally a cheap broom handle, PVC, wire, and zip ties, but it works great!

Or not. I was getting wonky readings and discovered the NanoVNA I have is only good up to 1.5Ghz. Units that go into BT/Wifi frequencies cost 3x or more what I paid for mine. If I get a nicer one, will I use it enough to justify the cost? I'll have to think on it.
D'oh.
D'oh.

I have a new toy. It’s definitely not useful for my job - I would need a much bigger one to overcome the loss in ~300 meters of rigid transmission line - but I should probably fine-tune the Diamond NR770 antenna I’ve had on three different vehicles now.

Indeed, I have had this fun too but I find that tuning up the antenna using a nanoVNA before hooking the set up works best and is much quicker really.

Slow Work Day: Let’s sort ferrite! Made a quick ferrite material sorter using NanoVNA-H4 and a two-turn test loop. Ended up finding at least four material types. Now labeled in separate bags and ready for (easier) future use!
