The Every Night 160 Meter at 1.895 is one of these fine groups.
Typically a “Pre-Net” forms in the half our or so before the net. Resulars who cannot stay for the full net sometimes drop in during the “Pre-net” asking Net Control to pass on their regards to the group as a whole.
At net time the Pre-Net callsign list is read and then check-ins are asked for. Once the list is set the first round goes around, with folk sharing something about their day and radio.
At the end of the first round additional check-ins are sought, with the added being given a round one opportunity.
Then a “73 Round” goes down the list, with each member given their regards to the group.
The afterglow can sometimes carry on for a while as special interest are explored informally.
Nothing fancy, just good honest folk all on the air together with Gentlemen & Ladies proper form.
I’ve check in several times over the years, and have met a number of the fine folk who participate on the net.
Check it out. There ar similar casual nets on other bands and in other geographic areas.
