Ha! Loved Dave's (W0LEV) fire alarm story! :) I did the exact same thing a couple years ago in my 3rd floor apartment back in Texas. I was using my SlinkTenna dipole (Google it) and had a blast for

NanoVNA F V2 not working correctly
I have 2 VNAs . H4 and New F v2. Using the H4 to measure coax length I get a reading that's spot on. But when I use the F V2 the reading is like 60% or more / greater than it should be. H4 at marker

Re: how good is a rain gutter antenna
In this case, Dave, it's highly likely the gutter system will have much more loss than the transformer. A gutter can be a reasonable antenna if all of the joints have good RF connections-but that

Re: Apologies if flogging a dead horse! CAL Correction?
Inadvertently I had done just that, because in using the VNA for the first time for real, tuning the ATU for 40m on the G5RV antenna, I was getting unbelievably perfect results because the MFJ969

After completing a cal, it's always a good practice to go back and verify that your OSL actually displays as an OSL. Dave - W?LEV [email protected]> wrote:

Re: how good is a rain gutter antenna
With the maximum SWR ¡À 2.5 : 1, you must have a lot of loss in the system. Likely due to that crazy 9:1 transformer. You have a NANOVNA, so measure the through loss of that transformer. I'd suggest

Re: Apologies if flogging a dead horse! CAL Correction?
Oh, and the 'correction' option in the menu is in -newer- nanovna firmware, so if your friends doesn't have it, he doesn't have the latest firmware. So yes, this was a valid question to ask, since

Gareth, This option is simply a switch that turns the calibration on and off. When it is checked, it is on. But the main status is at the left side of the display, along the center-left edge. If
