I listened until 0620 UTC but it was a low-elevation pass. The next 3 will be over 30 degrees. 73s Bernhard VA6BMJ @ DO33FL

Nothing here either: 0606z pass over California
by Greg D. 12 Apr '11

No signal on 145.950 here in Cal. With my luck they probably started the 15 min timer just before LOS... By the way, confirming the earlier post about inconsistent KEPs. Gpredict updates from Celestrak, and was slightly behind Predict which I had loaded from Amsat.org website. (I use Gpredict for pass prediction and eye candy during a pass; predict drives my rotor and Doppler shift radio client.) Greg KO6TH

Added a photo of me working (unsuccessfully) a pass of the ISS this evening (9:32PM PDT, Riverside, CA DM13). In the background, FirstOrbit.org's incredible film that will be released to the world tomorrow - a re-creation of Yuri's 108-minute flight, taken by modern cameras aboard the ISS. http://gallery.me.com/clintbradford#100077 Clint, K6LCS Skype - clintbradford

Another poor pass for me ... nothing heard. BUT AT 11:06PM PDT - a whopper of a pass. Followed by a pass in the morning that should be VISIBLE! ("Honey, brew another pot o' coffee, will you please?") Clint, K6LCS 909-241-7666 - cell

... over Vienna at 03:25UTC with 47 degrees elevation. Automatic antenna tracking seems to be nearly perfect, but no signal ? The CW decoder of ARISSatTLM produced a random string of characters including ...HIHI... 73, Viktor OE1VKW

ARISSat-1 update
by Gould Smith 11 Apr '11

11 Apr '11

As Armando, N8IGJ noted in his earlier email, NASA as published an update of today's activities ( it can be found at :http://www.nasa.gov/directorates/somd/reports/iss_reports/index.html) .Contained this document is a section about ARISSat Dmitri performed hardware setup and test activation of the TEKh-43 Radioskaf-B "Kedr" microsatellite in the MRM2 Poisk module, connecting it to an 825M3 Orlan battery and checking out its 430 MHz transmitter from the satellite control panel. [The small satellite was named Kedr in honor of the call sign of Yuri Gagarin. It will be activated onboard the station tomorrow, April 12, i.e., Cosmonautics Day, when the world celebrates the anniversaries of the first human flight into space and the first Space Shuttle flight. Development, manufacturing and launch of Kedr is the first phase in Russia's integrated program approved by UNESCO, with the goal to create and operate mini-satellites with a mass less than 100 kg by combined efforts of students across the world. Once Kedr is activated, it will transmit 25 greetings in 15 languages, pictures of Earth, and telemetry data from science hardware and support systems, as well as historical audio recordings. 50 years after Gagarin's flight all ham radio operators across the world thus will have a unique opportunity to hear the famous "Poyekhali" (Let's Go!) from Earth orbit.] Some clarifications: ARISSat-1, RadioSkaf-V, RadioSkaf-B, Kedr are all names for the same satellite. It is doubtful that the satellite will transmit pictures of earth as it is inside the ISS. ARISSat-1 only transmits on 2M. The ARISS team has arranged for the TM-D700 transceiver aboard the ISS to also transmit the ARISSat signals on 437.55 MHz. There are 24 different messages that will transmit in a sequence, one of which is the Gagarin-ground station conversation. The crew operates on UTC time and sleeps from 2130Z - 0600Z usually so probably no activity until after 0600Z The 12 April schedule found at http://www.nasa.gov/pdf/534825main_041211_tl.pdf doesn't specifically list an activity to turn on ARISsat-1 Keep listening, we'll let you know more as we know more. 73, Gould, WA4SXM

Re: The Need for Phonetics
by nh6vb Scheller 11 Apr '11

11 Apr '11

Glen et all, Once upon a time, during WWII, the phonetic alphabet started: Abei, Baker, Dog.....etc. With the advent of NATO, it was soon realized that the American version, or any ones else, was not suitable for international communication. Soon the NATO phonetic alphabet was developed by the military, and became international standard. The present international phonetic alphabet defines the letter K as KILO, not kilowatt. It would be very helpful for the amateur community to stick to established international standards and not bicker with their own cute substitutes. Citizens band has infiltrated ham radio to the point of satellite communication. Even as amateurs, let's be PAPA ROMEO OSCAR FOXTROT ECHO SIERRA SIERRA INDIA OSCAR NOVEMBER ALPHA LIMA. 73, Peter, NH6VB > From: kc6uqh(a)cox.net > To: gzook(a)yahoo.com; amsat-bb(a)amsat.org; mspencer12345(a)yahoo.ca > Date: Sun, 10 Apr 2011 11:28:52 -0700 > Subject: [amsat-bb] Re: The Need for Phonetics > > Glen, > Engineers use KW for kilowatt.
