That's something I can't work out.
Radios aren't rocket science. With modern digital radio systems,
and high
capacity batteries, there's no valid engineering reason why they
can't
work fantastically all the time.
Yet you're right: so many gliders have stupendously shitty radio
systems,
and it's just accepted as normal.
Why is that?

Yes Mark,
That was rather the point. Robert missed it completely.
Sanctimonious blather about safety doesn't cut it when you are
prepared to tolerate safety aids that don't work properly (or
inexperienced, well meaning, bumbling amateurs with little to no
formal
training actively encouraged by the system to pretend to be acting
as
"flight instructors").
As you said, it isn't rocket science.
No it's not rocket science to have good radios - but then neither is
it rocket science to realise that an aircraft relying on battery
power can have problems with its system. For example, I have had a
perfectly good fuse blow on a battery for no apparent reason (faulty
fuse maybe?) that took out the power (and hence the radio). On many
(most?) gliders the fuses are not accessible in flight.
A fall back is just plain sensible under these circumstances.
You are entitled to think it's "sanctimonious blather" but then I am
also free to disagree with you, albeit politely in my case.
