Yes of course, what you say is perfectly valid. But that will allow you to set up the subdomain yt9tp.ampr.org on the DNS, not ampr.org as you described it:
Thing is, when I asked to set ampr.org subdomain on my own DNS server, it was refused. It was said that it is not allowed, and all subdomains must be set on ampr portal.
You should have asked for yt9tp.ampr.org, not ampr.org.

Maybe we do not understand. I think it is perfectly valid to have for example
yt9tp.ampr.org. NS ns1.mydns.org. yt9tp.ampr.org. NS ns2.mydns.org.
That would allow me to adjust domain yt9tp.ampr.org and subdomains like
www.yt9tp.ampr.org ftp.yt9tp.ampr.org mail.yt9tp.ampr.org aprs1.yt9tp.ampr.org aprs5.yt9tp.ampr.org cluster.yt9tp.ampr.org sdr.yt9tp.ampr.org echolink1.yt9tp.ampr.org wifi.yt9tp.ampr.org
or other domains without further need to deal with ampr.org DNS server directly, but use my own.
