HF simulator product

[Stefan Moscibroda]

Dear all,
I'm currently investigating possible products for HF channel
simulation. The simulator should work bidirectional (to test also
ALE), it should simulate multipath (0-10 ns), Doppler Shift and
gaussian noise. For our purposes a base-band simulator would be
sufficient. Some of the products I investigated up to now are very old
and not currenty deliverable. I'm interested in new products (maybe
based on PXI, Labview) already develloped and ready to deliver. Does
anybody know such product? If there is somebody (or some institution)
which could lend us a cannel-simulator (broadband, allowing FH) for a
specific time, that would be of interest also. Thanks for your help!

Stefan,

Its been a while but I remember that someone had a pretty sophisticated HF
noise simulator. I think it was at something called packet radio.

Try the following site:

But I can't guarantee that's where it was!

Well, not a commercial product, but http://www.qsl.net/ae4jy/pathsim.htm

seems to do everything you ask, but I'm not sure about doppler. 10ns
seems like an awfully low multipath delay, did you mean 10 ms? For
bidirectional you'll need two copies running.
