Very nice Chuck, this will be on my personal target list as well!
I have been on the MIA list for the last few days because we are buying a new 32' Travel Trailer RV (with a real desk!!!) and trading in our 23' travel trailer, which means I have been pulling out the LIFEPO4 Battleborn lithium batteries, restoring the old lead-acid style charge converter controller(s), removing my 2nd Victron MPPT solar controller for my 400-watts of ground-mounted Renergy solar panels, and just doing a lot of general cleaning and packing away. I hope to be back with my picnic table soldering in about a week.?
I didn't get the nanoVNA, but decided to exchange the value of one of my kidneys to pick up a Rig Expert AA-35 Zoom made in Ukraine. This one only does to 35Mhz, but it will handle my Tuna antenna adventures very well as I have a lot of Unun, toroid verticals, and speaker wire dipoles built that will need proper trimming for tuning. There isn't a lot of Rig Expert stock from UA left on the Gigapart shelves and with the factory being shut down in Ukraine I nabbed one as they are easy to use and have a large screen for my old eyes. I didn't need one that went to 3 Ghz, well, at least this week anyway. There are something like 9 models.
Now our half-ton truck is a little light for our new travel trailer ... it never ends, LOL.
Cheers es 72, Dave - KU9L

Taidacent RF Power Meter Calibration RF Power Measurement 1MHz ~ 10GHz -50~0dBm RF Power
The 0dBm level is 1mW.
The picture shows a measurement of -51.2dBm, about 7nW.

I¡¯ll be buying one.? About $60...

I have a low resistance measuring meter from this company.
I measured some 1% SMT resistors between 1 Ohm and 0.1 Ohm with good results.

Yes, I know about 4-lead resistance meter measurement.? One company where I worked used them for measuring contact resistance in cross-bar switches.
