Built a 2m halo horizontally polarized loop antenna to try to make local 2m SSB contacts. Referred to KP4MD’s QSL webpage on halo antennas. Used #14 solid wire and a SO-239 connector. Tuned match point with NanoVNA-H4 to get close then tweaked wire-ends spacing to be even better. This is not an outside antenna in current form. Completed a quick FM test QSO with W9ELG in Elgin, IL. #HamRadio |

I went out today for POTA RO-0109 #HC29S in front of this communist mammoth #HC13S, operated all day on 36Ah #HC36S (ha!). I worked one DX, the ITU HQ, out of today's DXpeds PJ4M, VP8DPD and V73MT #HC07S, 14 DXCCs #HC37s, plus all xOTA #HC16S I heard. I had 20 contacts on CW #HC38S including @YO3AX and @G0TRT. I even heard F4JRC on 6m #HC28S. I fixed my audio card #HC45S and used the antenna I built with the YL #HC33S. |

Just made a nice simple portable 40m dipole using the brilliant UniBalun by @DG1JAN! My first time winding a toroid went better than I expected, and the kit is nice and easy to solder up. I'm hoping to take it to work on Monday where there's lots of space, and get it tuned.#HamChallenge HC33 |
