Do balloon pilots use an aircraft band radio frequency to communicate
with their ground crews? If so, what frequency is used, and how does
the ground crew identify itself? I would expect the FCC to require
that some type of "station ID" be used by this "station".

Hi Folks,
I am hoping to get some help with a design project I have been asked
to look into.
I would like to design a hot air airship that will be electrically
powered from the ground via the teather.
The airship needs to be hot air as there will be no helium available
where it will be going.
The idea is to teather it so it can't get away and to power it. Its
going to carry a digital camera and simple video transmitter (areal
photography platform). I want it powered so I can drive it into the
wind over the target site.
Only problem is I don't know where to start! Anyone any advice?
Many thanks
Richard

Being a little hot, buoyant and having 10%% less gravity is actually a
darn good thing if you were a Venusian airship, even if limited as to
an oven-wrap or KetaSpire PEEK polyetheretherketone and fiber
reinforced balloon. Such fiber reinforced composites do exist,
although an outer skin of something in basic titanium shouldn’t be
excluded for this rigid airship configuration.
For this topic I have an unusual airship to R&D, as intended for a
rather toasty dry and calm environment. Think of this application as
a floating city if you like, or consider this one as merely a small or
as large as need be robotic probe that can remain efficiently aloft
for nearly unlimited time without much energy demand while drifting or
even when cruising along at perhaps an average air-speed of less than
10 m/s, as such wouldn’t demand but a few kw for managing a good sized
airship.
