Hi George!
Although the LoTW FAQ shows "ARISS" and "AO-7" as the valid satellite names, TQSL bounced all of my QSOs for those two for "Invalid Satellite Name"... I looked in the ADIF file, and the Sat_Name fields are all correct, and it processed all of my other QSOs successfully. I also tried "ISS" and "AO-07", and it bounced those, as well.
Any hints?
You may want to e-mail lotw-help @ arrl.org about that. I used "ARISS" as the satellite name for the ISS cross-band repeater, and "AO-7" for that satellite, without any problems. I was only waiting for SO-67 to be put in that system, by the time I started uploading my QSOs a few weeks ago (it is in there now).
LOTW was down for some period of time yesterday (Sunday) afternoon, so maybe something has happened to it in the recent past.
73!
