I decided to take down my antennas today. The SWR is terrible on my sloper, and there are NO users on 17m, just a couple of fluke packets heard from OH6DL back in April, and pre-planned operations with WA7GMX, W7BMH, and a few others way back when, which I appreciated. At the same time, this is feeling much like my original packet radio days, just the same few callsigns on most days, but less of them lately. The house needs roof work anyways, so what better time to take a break. I will try and get some new antennas put up again in the 'fall' (hopefully) ...
