[amsat-bb] Satellite Operation from the USS IOWA
Greetings, all I'll be operating for the BSA JOTA event from the USS IOWA in San Pedro on 20 October from 1600 UTC to 2300 UTC. We'll be using the callsign NI6BB. Pass predictions indicate we can use FO-29, AO-27, and AO-7. I'll concentrate mostly on the linear birds, as I "kinda sorta" don't want to expose the Scouts to the pandemonium of an FM satellite on the weekends. I *will* listen, though, and if it doesn't sound too crowded, I'll try and make some FM contacts, too. We also have a couple of great ISS passes, but I don't know what mode the ham station on the ISS will be in that weekend. Hope to work some of you from the IOWA! 73, Jim KQ6EA ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: satellite spectrum
Not sure I understand why 50 cubesats in orbit for 3 - 6 months doing atmospheric research will 'cause stress' on bandwidth. If you have a generous 20kHz spacing to allow for +/- 10kHz doppler, then we have 1MHz of spectrum. OK, there are other occupants than need to be avoided but there are 3MHz available. Sounds like a good use for a reworked version of ' CW skimmer ' Thanks David G0MRF There is, however, no denying that the Amateur-satellite Service requires more spectrum. The key spectrum for us is at VHF/UHF below 1 GHz but we only have two allocations - 435-438 MHz on a secondary basis, shared with the Military, SAR satellites and others, and the 144 MHz band of which only 200 kHz, 144.8-146 MHz, is available to us. You can see that when the QB50 project deploys 50 CubeSats it's going to put the available spectrum under stress. -Original Message- From: Trevor .

[amsat-bb] Elections- Hudson Division
My Apologies in advance, this is off topic, however this is an important election, Mike was part of our team that spoke with Rep. Pete King on HR 607, thank you. WB2OQQ AMSAT- HUDSON DIVISION ARRL MEMBERS I am supporting Mike Lisenco N2YBB for the position of Hudson Division Director. Mike has a long history of service to the Amateur Radio community. He is currently the Section Manager for the New York City/Long Island Section. Mike has demonstrated that he understands both the hobby and the service aspects of Amateur Radio. He is an active ham who participates in Emergency Communications. He was an ARES District and Section Emergency Coordinator and a RACES Radio Officer. He also enjoys operating in contests, chasing DX, and just plain ragchewing. His extensive field experience gives him the knowledge base to understand the policies that need to be instituted by the ARRL. I believe he will bring new ideas and a fresh approach to the League. He listens to the opinions of the membership and incorporates their ideas into his plans There are 15 Directors in the ARRL. Their purpose is to develop policy that affects all hams for years to come. Leadership from the Hudson Division Director is crucial to the future success of Amateur Radio. . I know that Mike is strong enough to represent the interests of the Hudson Division in Newington. He has the time and the ability to best represent all of us. In my opinion, he is the right choice for the job. It is important that you vote. Starting October 1 balloting will be open for ARRL Hudson Division Director for those who have an email address on file with ARRL. You will receive instructions on how to vote electronically. Paper ballots will be mailed for those ARRL members who don't have an email on file. Join me in voting for Mike N2YBB when balloting begins next week. If you would like more info about Mike, go to his website www.hudsonhams.com 73, Pete WB2OQQ ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] satellite spectrum
The conclusion of the recent WRC conference left open issues concerning the allocation of spectrum for pico and nano satellites. The requirement was identified as serious and will be an agenda item at the next WRC. In my opinion, this will put pressure on ham allocations from 5.8 GHz and down. I read about this in the current issue of ViaSatellite magazine, a publication geared to the commercial satellite industry.

[amsat-bb] Re: FITSAT-1
Dear Ham friends, JAXA has postponed the deployment of FITSAT-1. I made mistake. My following explanation is wrong: > The orbit is almost the same as ISS. Jaxa said FITSAT > delays 200 m from ISS for one cycle around the world. > As it goes around 16 times a day, it delays 3.2km per day. > If 10 days have passed after deployment, FITSAT passes > the same point of ISS after 4 sec (32km/8km=4). JAXA said FITSAT goes away 200m from ISS for one cycle, not delays. As FITSAT is pushed out backward from ISS, its speed goes down, and the altitude decreases. As the altitude is lower than ISS, FITSAT goes around the world faster than ISS. So, FITSAT advances than ISS. Best Regards, 73 -- Takushi Tanaka JA6AVG ___ Sent via AMSAT-BB@amsat.org.
