Great! Congratulations. I guess we have to wait until the sat is in the "dark" to use it here in NA. Just wondering why you would activate the transponder without having power through the solar panels and consequently discharging the batteries (unless that's the intent).

Would the transponder mode potentially have lower average power consumption than full power telemetry mode? In full power telemetry mode, it's putting out 300 mW the whole time. In transponder mode, it's only putting out 30 mW + whatever it's taking to relay the signals it's receiving. The transmitter would only be putting out full power when it's in use. Unless my thinking is completely wrong here... 73, Paul, N8HM On 11/23/2013 5:48 PM, Stefan Wagener wrote: Great! Congratulations.

Good point. Now from what I read they are running the telemetry mode at the same time with lower power.

[amsat-bb] Re: Funcube-1 - Ao-73
Hi All, Yes in telemetry (also known as educational) mode we have around 300mW and this is a much higher average RF output than when in amateur (also known as transponder) mode. Total current drain is therefore greater when in educational mode. This is convenient because we had planned that educational mode would be more useful when the spacecraft is in local daylight - ie schools would be more likely to be open. This is the primary mission of course. Also amateurs often have to work during the day so would appreciate the availability of the transponder during the local evening passes. We were not, before launch, 100% certain that we would have a good enough power budget to run the transponder during every eclipse period but, at the moment, this seems to be ok - we still have quite a positive power budget. Its a bit late here and we are quite tired after three very hectic days but I hope the above explanation makes some sort of sense:) best 73 Graham G3VZV -Original Message- From: Stefan Wagener Sent: Saturday, November 23, 2013 11:13 PM To: Paul Stoetzer Cc: AMSAT BB Subject: [amsat-bb] Re: Funcube-1 - Ao-73 Good point.

[amsat-bb] Re: FUNCUBE-1/AO-73 reception issue
Steve, I don't know if I can help. I am using a Kenwood TS 2000 X with an interface to go between the audio output in the back of the rig to the input of my HP laptop. I just have an M squared eggbeater without any pre-amp for receive. My tracking software is SatPC32 to correct for the doppler effect. I only touched up the downlink a couple of times on each of the two passes I recorded and uplinked to the warehouse (147 frames). I Load SatPC32, have it running, Load the dashboard software and choose to capture from the soundcard. The audio output of the RASCAL interface goes into the input to my sound card. I have the volume up at about 75%. Before the bird comes over the horizon, I see a wave on the Dashboard software that is the result of the noise coming from the receiver. I can actually hear the bird about 20-40 seconds before it comes over the horizon (very faint but hear the distinct tone). The real time screen starts filling with data as I see on the right bottom counting of the type of data received, the serial number, and to the right, the packets decoded and missed, plus the number of packets already sent to the warehouse and the number waiting to be sent. Don't know if that helps at all. Having taught Earth Science and Astronomy for 36 years, now retired, I not only like the linear transponders, but love to collect telemetry from the birds too. It is not available yet, but I can't wait until they allow us to download the whole earth orbit data from the warehouse. I want to watch the data change as the bird goes around the earth. I used to do that with UO-11 telemetry and use the data for labs using Excel's graphing functions in my Astronomy classes with my students. Did you try decoding the sample wave files they provide? They allow you to experiment getting the audio to your soundcard, then to the dashboard software. I'm looking forward to the 03:41 Z pass for me later tonight.

Hi Rick Am using HRD for tracking and Doppler, but for some reason I am not hearing the Satellite at all. Have checked the Antenna but perhaps a Tri band Co-linear antenna is not the best antenna to use.

Ok Steve. I am listening to 145.935 MHz +/- doppler in the USB mode. The bird is using power output which is a little higher than originally planned but still lower that normal use in the future. It has a nice strong signal here. I would think you could hear it with a 1/4 wave whip or ground plane antenna on a high elevation pass. My eggbeater is only 10 feet off the ground with a large pin oak tree blocking to the south and my house blocking to the north. Hope you get to hear the bird. Let me know if I can help in any way.

I have an interface between the radio and soundcard that I have also tested that, but I am not hearing the satellite let alone getting to decode, I did perhaps think I had got confused about the frequency and radio mode. Thanks very much for the reply though for the useful info Steve Daniels Amateur Radio Callsign G6UIM APRSISCE/32 Beta tester and WIKI editor http://aprsisce.wikidot.com _ From: Rick Walter [mailto:wb3...@gmail.com] Sent: 22 November 2013 22:18 To: Steve Daniels Cc: amsat-bb@AMSAT.Org Subject: Re: [amsat-bb] FUNCUBE-1/AO-73 reception issue Duh! Brain fade Steve. That pass is 2:36 UTC. Also the first things I mentioned I watch are on the left bottom for the screen.

I am using a Kenwood TS 2000 X with an interface to go between the audio output in the back of the rig to the input of my HP laptop. I just have an M squared eggbeater without any pre-amp for receive. My tracking software is SatPC32 to correct for the doppler effect. I only touched up the downlink a couple of times on each of the two passes I recorded and uplinked to the warehouse (147 frames). I Load SatPC32, have it running, Load the dashboard software and choose to capture from the soundcard. The audio output of the RASCAL interface goes into the input to my sound card. I have the volume up at about 75%. Before the bird comes over the horizon, I see a wave on the Dashboard software that is the result of the noise coming from the receiver. I can actually hear the bird about 20-40 seconds before it comes over the horizon (very faint but hear the distinct tone). The real time screen starts filling with data as I see on the right bottom counting of the type of data received, the serial number, and to the right, the packets decoded and missed, plus the number of packets already sent to the warehouse and the number waiting to be sent. Don't know if that helps at all. Having taught Earth Science and Astronomy for 36 years, now retired, I not only like the linear transponders, but love to collect telemetry from the birds too. It is not available yet, but I can't wait until they allow us to download the whole earth orbit data from the warehouse. I want to watch the data change as the bird goes around the earth. I used to do that with UO-11 telemetry and use the data for labs using Excel's graphing functions in my Astronomy classes with my students. Did you try decoding the sample wave files they provide? They allow you to experiment getting the audio to your soundcard, then to the dashboard software. I'm looking forward to the 03:41 Z pass for me later tonight.

I seem to have the correct keps as I see station near me uploading. Am using a radio not a dongle 145.935MHz USB mode is what I am using as settings.

[amsat-bb] Re: FUNCUBE-1/AO-73 heard over Camagüey, Cuba !!!
Congratulations Due to work time constraints I has not been able to give it a try yet Pavel and Hector, please send the .funcubebin compressed in ZIP to my GMAIL account (cm2espgmail.com) I will try to upload it next Monday I have access to a direct Internet Connection at my workplace. 73, Raydel, CM2ESP EL83sc El 22/11/2013 0:02, Pavel Milanes Costa escribió: Hi and congratulations again for the FUNCUBE team. Hi have received AO-73/FUNCUBE with strong signal here in FL11BJ (Camagüey City, Cuba) around 0350Z of 22/11/2013, that correspond to orbit #12. Equipment here is a J-pole 7m height, homebrew LNA (TKS Domenico !!!), RTL-SDR with Gqrx > file and the later replayed into dashboard software... The collected data will be send to HLMS (CO6CBF) to route it to the warehouse in the internet, because I suffer from the same problem that him... not direct internet connection here. 73 and will keep track on AO-73 ___ Sent via AMSAT-BB@amsat.org.

Take a look at http://warehouse.funcube.org.uk/realtime.html?satelliteId=2#tabs-rf You'll find max and min values listed for each telemetry channel. For example the comm system temperature ranges from -6 to 19.7 degree C Lots to explore on that website. 73, Drew KO4MA -Original Message- >From: Rich/wa4bue >Sent: Mar 18, 2014 7:44 AM >To: M5AKA , AMSAT BB >Subject: [amsat-bb] Re: FUNcube-1 (AO-73) Continuous Transponder Test Update > >What are the temperature extremes on the satellites. > >God bless > >R >W4BUE >___ >Sent via AMSAT-BB@amsat.org.
