I'm using a "trackable Elk" antenna when I work NO-84. OK, I am
holding the antenna and pointing it at the satellite, twisting as needed
to keep up with what the satellite is doing in orbit. As I mentioned in
my earlier post, I am using a TH-D72A HT - just 5 watts. What path
(UNPROTO) are you using with NO-84? PSAT doesn't work, but
ARISS or APRSAT will work. I've used both of those successfully.

Remember that NO-84 transmits in the millwatt range, where ISS
has many times more transmitter power for packet. I think this is also
where many of the gateways are having difficulties with NO-84 - it
just isn't as strong as the ISS.
