Talking on a Handy Talkie (HT)

I'd like to add to this, as someone who listens to radio traffic most days all day and hears a wide range of audio quality. Dennis is right about holding the microphone about one inch from the mouth,

Let me start by say this at least one time, "An HT is NOT a cell phone!" I know, it's hard to break the habit. New users of HT's (and some not-so-new users) tend to hold and use an HT like a cell phon

NanoVNA User's Guide

One of the better, simpler User Guides that I found, with good menu maps and screen shots. Of course, there are other more in-depth manuals available, and I've attached a translated version of one as

Thanks for this, Dennis. Some of those menu items are really buried, so this is a great help! -Phil KM6NFS

I'm not sure about you, but I like to see ALL the menus in a multi-layer menu system like the NanoVNA (7 levels). I found this printable menu map and thought you may want to print a copy for reference

A small loop mounted horizontally behaves like an E-field antenna and needs to be elevated. I tried it once out a 4th floor hotel window. Didn't work well. All the loop needs is a capacitor to tune it

Thank you Skip for the link to the loop antenna radiation calculator. I was looking for that, but couldn't find it! Are you operating your Alex Loop in a horizontal position so the null is towards you

Jef points out a couple of advantages [and disadvantages] of small transmitting loops. The circulating current will be high with any appreciable power. The radiation resistance is in the milliohm rang
