Any idea what the chances would be of having something like 1 night a week or month, on ONE of the FM birds, that could be reserved for HT access only?

My thinking on this would be a great way for people to test out their portable or limited satellite stations with a great deal less collisions against all the other much stronger stations.

I have heard from plenty of people that would like to try a temporary or portable station on the birds, but we all know that’s not even a remote possibility unless your on super early in the morning or late at night.

As it happens I was trying a new radio for a portable setup last evening (I bought a KG-UV1K to get full-duplex capabilities).

On a not-to-high pass yesterday evening (max 21 degrees elevation with lots of buildings around) I did hear AO-92 and could understand some of the callsigns, but could not get in at all. Mister Ollaaaa was also active on some occassions. I will try again on a higher pass.

My plan is to bring it along on an upcoming holiday, which will be in a somewhat rare grid. But since it's a holiday and I'm not sure when a pass will be at a usable time, I'm not going to announce it as an activation. I may just make a few contacts.

So I'm the 'target audience' for your idea, and I really think it's a good idea.
