JARTS is the annual Japanese Amateur Radio Teleprinter Society contest: http://jarts.jp/
I wasn’t taking the contest seriously this year, the focus was really to experiment with some new antennas. 10m was surprisingly quiet (noting that there was quite a bit of 10m FT8 activity through much of the contest). 15m was noticeably better than the band has been in contests for some time (although not sure if that is down to better band conditions, improvement in the antenna system here – or a combination of both!). Typically I would expect to do a big session on 20m during JARTS but it didn’t feel like I was on the band much at all.
It’s a struggle with 100W sometimes and was noticed on 20m and 15m in the morning when JA stations could be heard but not worked. Apart from that, pretty much everything which could be heard was worked with VY5 on 40m a got-away despite many attempts.
