Questions About Promoting NTS kc1pyt on 9/5/22
I listen in to a nearby NTS net on a regular basis. I'm struck by how few messages get passed some days. I readily see the value of NTS. In a disaster Joe Six Pack is not going to know how to setup Winlink at the drop of a hat with no access to the Internet.

I feel like there is more we can do as hams to promote the service. Some thoughts that occur to me:

* Why not establish a new tradition of having regular intervals where hams send NTS messages to each other?
* If that's not enough, chess by mail[1] has a long history in this country. It seems like it should be relatively trivial to adapt that to NTS and get several games going.
* I got one friend interested in ham radio just by sending him a holiday message via NTS. So, it seems like it might be a good "recruiting tool" for some.
* Promoting NTS to hams in countries where it is not an established practice.

I am still very much the new guy here but I just wanted to share my thoughts. Does anyone else here have any ideas for promoting NTS radiograms to the wider ham community or the general public?

New ham (AG) here with a question. I'm going to be making my first antenna soon and there is something I just don't understand. I see antennas available for sale that are rated for a given number of watts. Sometimes its as simple as a fixed watt amount. At other times it's something more complex like "100 watts FM, 25 watts packet" or some similar duty cycle qualifier. I get that "RF gotta go somewhere" and a certain amount of RF is lost as heat with every transmission. But, what part(s) of antennas are subject to failure at higher wattages?

More to the point, when I design my antenna, how can I be sure from a design and materials perspective that a specific antenna can withstand some number of watts for a given amount of time at whatever duty cycle I anticipate? My antennas are mostly going into my attic, so I *really* don't want to create a fire hazard.
