[amsat-bb] Re: seeking examples of frequency bands used in amateur spacecraft

[Arthur Feller]

Hi, Samudra!

The last major change in frequency allocations to the amateur-satellite service came from the 1979 General World Administrative Radio Conference.  Domestically, the changes became "official" upon the consent of the US Senate.

Suggest reading the paper on "Amateur Satellites" on the IARU web site and looking at the Annex with the frequency allocations.

AO-40 attempted to use most of the UHF and SHF bands.

No power limit is specified in the RR's.  At the same time, the principle of using the minimum power necessary still applies.

I hope this helps.

Hello with reference to the US FCC Part 97 and in particular section 97.207
"Space Station" available
http://www.arrl.org/FandES/field/regulations/news/part97/c.html#207

Have all of the frequency bands listed below been used in service through
the last four decades?

The following frequency bands and segments are authorized to space stations:



   (1) The 17 m, 15 m, 12 m and 10 m bands, 6 mm, 4 mm, 2 mm and 1 mm bands;
   and

   (2) The 7.0-7.1 MHz, 14.00-14.25 MHz, 144-146 MHz, 435-438 MHz, 1260-1270
   MHz and 2400-2450 MHz, 3.40-3.41 GHz, 5.83-5.85 GHz, 10.45-10.50 GHz and
   24.00-24.05 GHz segments.



What power limitations are stipulated for these bands?
