I looked at my record for JT1CO. There is no QSL in LoTW for my 20M CW QSO as it was confirmed by paper. But, I can go to my list of 20M confirmed entities and pull up this record under QSL Card Detail.
Worked Station
Worked JT1CO
DXCC MONGOLIA (363)
Date 2012-05-26
Mode CW (CW)
Band 20M

In contrast, a WAZ contact confirmed by LoTW ends with the time of confirmation as this is known to the nearest second.
QSL 2012-09-05 08:05:35

The list of LoTW contacts won't show paper QSLs. To see the paper QSL record you need to go to the award listings.
Satellite using an HT KB8VHI 4 days, 6 hours ago

"It is preferable to work the FM sats in full-duplex mode (where you can hear the downlink as you key your mic). But only one recently manufactured HT did that well in V/U and U/V modes: the Kenwood TH-D72a (discontinued 4Q 2020)"


In practice most dual band radios desense too much on receive so it is often more practical to use two radios if you are on a budget.

What Determines How Many Watts an Antenna Can Take? jgaz 1 week, 2 days ago
There are now infrared cameras sold to consumers. Some are phone attachments. These can be used to verify the expected temperature rise of antenna components.

Even better would be to use a professional grade camera used by fire departments. Perhaps they would be willing to come out with their gear to make sure there are no issues in your attic.
