nullagentCleaning up the wiring and checking antenna SWR with a NanoVNA.Was curious if these cheap antennas were similar to their name brand look alikes. And no, no they are not comparable lol. Stick to the name brand I guess for this style of antennas, the cheaper ones are not worth it this time.<a href="https://partyon.xyz/tags/lora" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lora</a> <a href="https://partyon.xyz/tags/meshcore" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#meshcore</a> <a href="https://partyon.xyz/tags/meshtastic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#meshtastic</a> <a href="https://partyon.xyz/tags/nanovna" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nanovna</a> <a href="https://partyon.xyz/tags/radio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#radio</a> <a href="https://partyon.xyz/tags/antenna" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#antenna</a>

It's heavily inspired from these existing TestBoard-Kit but (hopefully) less confusing to use.

Pete Prodoehl 🍕I borrowed a NanoVNA from <a href="https://rhizospherelabs.com/@mathias" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@mathias</a> and tested my Meshtastic antennas... The one shown here (with a 915MHz sticker) appears to actually be okay! It was an AliExpress find.(For anyone smarter than me, does this look good? SWR of 1.225 acceptable?)The antennas that ship with the Heltec V3 boards seem to be pretty bad at 3.998. (Well, they do come free with it.)<a href="https://mastodon.social/tags/meshtastic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#meshtastic</a> <a href="https://mastodon.social/tags/nanovna" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nanovna</a> <a href="https://mastodon.social/tags/antennas" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#antennas</a>

Damit ich die KW Antennen auch schnell ordentlich abstimmen kann habe ich mir doch mal ein <a href="https://radiosocial.de/tags/rigexpert" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rigexpert</a> Messgerät zugelegt. Der <a href="https://radiosocial.de/tags/nanovna" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nanovna</a> kann das im Prinzip auch, aber ist letztlich doch etwas unhandlicher. Damit habe ich gleich mal den 10m Strahler am Bus überprüft. So kann ich die aktuellen Bedingungen auch nutzen.

Alex@rtnVFRmedia Suffolk UKLow pass filter worked - no big 3rd harmonic in military airband, not good round here (there are regular training exercises) and 2nd harmonic from TX doesn't upset reception of DAB+ muxes for a few metres around (although I'm in a remote area using low power, I would rather not create this QRM!). Cutoff point is higher than I wanted, but exciter doesn't create harmonics in civil airband (I checked for these!)First time I've built one of these filters.. <a href="https://social.tchncs.de/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electronics</a> <a href="https://social.tchncs.de/tags/radio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#radio</a> <a href="https://social.tchncs.de/tags/NanoVNA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NanoVNA</a>
