Let's try a 10fer for @hamchallenge : 
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.
Details follow.
@hamchallenge The condx were terrible and I really, really hoped for a 6m qso, but nothing happened. I did hear F4JRC, about 2000 km away, on the magic band #HC28S.
Contacting other xOTA stations wasn't as easy as the usual P2P or P2S, but I did get ~15 in the log, not counting multiple parks and multiple ops setups. #HC16S
I even had some CW qsos with other hams with whom I share this instance #HC38S, but I couldn't find someone for #HC30 #hamchallenge
