JT4F - Really?

Well

A bit more Wednesday night activity on 23cm digital modes; last night I worked Neil, G4BRK on JT4F, here's how it looked from his end:

And this is from my end:

Now, two main observations:

1. There is simply loads of Doppler or other effects - probably due to Aircraft Scatter / Reflections
2. The report I sent was received with an additional "000" on the end - I wonder why

But the decodes of this mode seem extremely reliable in the presence of  multiple reflections - which makes it ideal for this kind of frequency.

Good, egh?
