[amsat-bb] Need your support to track F-1 CubeSat
Dear everyone, According to latest news from JAXA, deployment of the 5 CubeSats to space by the robotic arm of Kibo module on the ISS will be carried out on Thursday, September 27. Here is the plan: - First, 15h10 to 15h20: WE WISH and RAIKO from POD #1 - Second,16h30 to 16h40: TechEdSat, F-1 và FITSAT-1 from POD#2 All time in UTC. The event is planned to be broadcasted live on the following websites: http://iss.jaxa.jp/iss/jaxa_exp/hoshide/library/live/ http://www.ustream.tv/nasahdtv 30 minutes after deployment from the station, F-1 will begin transmitting beacon alternatively on its main and backup channels. Telemetry and beacon data from F-1 contain critical information about the satellites health (battery solar cell voltages, temperature readings) and they are very important to us, especially in the first week of operation. Thus, we would like to ask the amateur radio community to help in tracking and receiving data from F-1 CubeSat. Heres a quick summary of F-1 frequencies: - 145.980 MHz: main channel, 1.0W RF output, FM, AFSK 1200bps, one telemetry packet every 30 seconds, operates in the dark by default (but can be commanded later to operate in sunlight as well) - 437.485 MHz: backup channel, 0.2W RF output, FM, PWM CW beacon, each beacon transmission lasts about 20 seconds then 60 seconds delay, only operates in sunlight More information and guide to download F-1 telemetry decoder can be found at http://fspace.edu.vn/?page_id=27. Decoded data can be submitted to us via the telemetry decoder or by sending to me directly (th...@fpt.edu.vn), audio records are highly appreciated. Please feel free to send me a message if there is any question. We would really appreciate your kind support! 73, Thu XV9AA F-1 CubeSat Project Manager ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: Ts2000 with external preamps
I have been using external (mast mounted) preamps for 2m and 70cm from ARR with my TS-2000 for 2 years and quite happy with their performance. These RF-switched preamps just work always and they're weather proof so virtually no maintenance is needed. Note that they can only handle maximum 160W RF, which is good enough for me. http://www.advancedreceiver.com/page10.html Thu XV9AA -Original Message- From: Bob DeVarney W1ICW [mailto:w...@myfairpoint.net] Sent: Saturday, August 25, 2012 1:06 AM To: amsat-bb@amsat.org Subject: [amsat-bb] Re: Ts2000 with external preamps I've had phenomenal success with the SSB preamps over the last 25 years. I have one for both 2 meters and 70 cm and if I had anything worth mentioning on 6 meters for an antenna I would have one there as well. Prior to that I used Landwehr. For my EME station I am using a DB6NT receive-only, only because at the time the Deutschemark ( or Euro ) was cheap and I could get the DB6NT cheaper shipped from Germany than I could get an equivalent SSB receive only here. I have no regrets, the DB6NT is a thing of beauty as only German workmanship can make. I see that ARR is now making an rf-switched preamp that handles some power now too, but I'd stick with the SSB if I were you, only because they will handle up to 700 watts if you sequence them; 200 RF-sensed.

It seems that with the particular preamp and xcvr I have a sequencer is needed to ensure dx is removed from the coax before rf is introduced. I think the easiest solution is to get a different preamp once I get my icom repaired. I could also swap it with the mirage I'm using at home with the 847 which I think is immune to rf or is switched. Unless you have an icom xcvr their preamps are a bad purchase. Thanks everyone.
