perfect groundtrack contest

I vote for Intelsat G-11 at 304.5 deg E. This is a Ku band only bird, however, the semi-retired Intelsat 805, which is co-located with this sat has a global C band beam with a downlink that extends into the amateur 9cm satellite band (3400-3410 MHz). I often wondered if Intelsat would consider "donating" a few Khz to AMSAT. We could then tie a single, commercially licensed uplink station via echolink and hear it on the 9cm downlink. At least it would be a reason for people to use the 9cm band before it's taken away for the latest mobile broadband gizmo. Howie AB2S

Re: ArduSat Arduino CubeSat Update

In short, yes, in my opinion, unless they applied for and received an experimental (Part 5 I think) license in the 435 band, which has happened before. Even then I think there is a legal issue with a amateur service station communicating two-way with a part 5 station. I don't think any of them are aware of this from what I can see. THe FAQ on their kickstarter page has the following: How do you communicate with ArduSat? Our current plan is to use GENSO, a network of amateur-band ground stations connected through the internet that allows you to use any of the satellite communication terminals on the network from anywhere else. By connecting our interface to the network, we can communicate with ArduSat whenever it is in range of any of the stations. This means we can access the satellite more often and for longer. As a backup option, we’re also looking discussing with private ground station operators for collaboration. Last updated: Friday Jun 15, 11:55am EDT I'm a big supporter of cubesats, but many of them need some education on the use of amateur frequencies in my opinion. 73, Drew KO4MA -----Original Message----- >From: "Trevor ." <m5aka(a)yahoo.co.uk> >Sent: Jun 15, 2012 2:08 PM >To: amsat-bb(a)amsat.org >Subject: [amsat-bb] ArduSat Arduino CubeSat Update > >The latest update on the proposed ArduSat. > >See http://www.uk.amsat.org/?p=8284 > >I wonder though about the fund raising idea of renting out time on the various space experiments. > >Not a problem on UHF commercial frequencies but would it fall foul of FCC regs if the 435 MHz band were used ? > >73 Trevor M5AKA > > >_______________________________________________ >Sent via AMSAT-BB(a)amsat.org.

ArduSat Arduino CubeSat Update
by Trevor . 15 Jun '12

The latest update on the proposed ArduSat. See http://www.uk.amsat.org/?p=8284 I wonder though about the fund raising idea of renting out time on the various space experiments. Not a problem on UHF commercial frequencies but would it fall foul of FCC regs if the 435 MHz band were used ? 73 Trevor M5AKA

IC910 Options
by Tom Lubbers K8TL 15 Jun '12

Still don't know how to answer direct but: I have the CW filter, It works but I have never needed it! Of course the 1.2 Ghz module hasn't been used since AO-40 died. I turn the 1.2 Ghz module on every once in a while to blow the cob webs out of my 2C39 amp. Also have the UT-106 module, not sure if it does much that is noticeable at this location. Only got the RX options for the main RX, couldn't anticipate needing the enhancements on both receivers at the same time. The CT-17 is real handy for interfacing the frequency tracking systems. In my opinion, if 1.2 GHz gets popular again there are better options than the internal module. Unless you got burnt on the price, the 910 is probable the best buy for satellite work around. You got everything but mode "A" and no bird on the ISS down link. 73 and see you on the birds, Tom K8TL
