Hi All MW experts!
Who has worked on this Italian MW products (http://www.siaemic.com/index.php?id=44)?
Its very important for me.
I've got some complects (without support) and i need help.
Many thanks!
Also, provide me please relationship between subband number (like 3L, 1L, 6H, 1H) and frequency values.
For example : 3L, 1L, 6H, 1H - 11, 18, 23, 38 GHz (I think its from ITU-R).

Thank you, but this docs from the official site, not problem for download if you'll be registered on the site.
If some one have a manual for installing, or other helpfull docs (for implementation equipment) i will be very grateful.

Once again Hello!
I need to test IDU's (above all). Early I had a antenna equivalent (waveguide attenuator) for trial a MW equipment on a table. Now, I dont know how can i test ("on the table") without an equivalent loadand and dont "burn" transmitters, or dont have influence on my head :).
Also, if i understand i cant connect IF modem to IF modem for IDU's test only, because they have a same frequency for up and down signals (like 130 and 340 Mgz).
If you have an expirience of check, verify MW on the table, please share with me.
I should check more then 10 links. it should not be difficult.
Any ideas? for simple testing ))

You just wanna create a connection between two ODUs without waveguide-to-coax and attenuators?
Just point both ODUs to a same wall and you'll receive some of the signal. Some point ODUs upwards to have the signal reflected off the roof, some like it sideways... Choose whichever position suits you best. :)
You can reduce output power if you're worried about frying receiver or losing hair, or having only daughters and no sons. :)

Hi Friend,

what about an IF loopback to test only the IDU? Do SIAE support them? :D

byja is totally right.. they do it all the time around here.. it's safe.. just reduce the Tx power, put them on table.. get them aligned to a specific level till you get your desired FM for operational testing and you are all set to go.
