i do wonder about some hams
i get one or two of these a month, over a year old QSO confirmations
this one is 3 years old!!!! think it a oldest one i have ever seen (Sending callsign blacked out)
i try and upload my logs to eQSL and QRZ at the end on a session or following day at the latest
LoTW i tend to upload quarterly as i don't use it for myself, but upload for those how actively use it
