When I use a VNA, am I essentially radiating a CW signal at my sample points and measuring various parameters of the reflection, right? And I am probably sweeping outside of my specific band(/license) I want, because I want to see where it is tuned. So essentially the VNA is unintentionally radiating and this is bad. ? My nanoVNA2 is prolly pretty low power (how much??), but sometimes I use the work $$$$$ VNA at like -10dB.... horse_ebookmarklet fucked around with this message at 06:17 on Feb 7, 2021 |

I saw that HB9BLA Wireless video where he used a MIDI console to control his transceiver. It made me think I could add MIDI to my IC7300 project, and perhaps disappoint too. Got a cheap DJ console and slapped some MIDI code together. Went surprisingly easy, except as a tone deaf rhythmless nerd I've never touched a MIDI. Thankfully MIDI is mostly reasonable to approach (7 bit signed integers tho lol) https://www.youtube.com/watch?v=Gcy9crqP1gU Proof of concept has the MIDI events hooked up in C++. Next is to add bindings to the Javascript API. Intent is users can write Javascript to make their own mappings, run macros, etc, and support different consoles, without having to recompile.
