There are 2 that come to mind: HamSat Droid and DroidSat. They both do different things and make a great combo. HamSat Droid is a satellite prediction app and DroidSat allows you to locate the bird in the sky like a spotter scope.

[amsat-bb] Re: Fwd: 420 MHz in Jeopardy!
I'm not sure how worried people are over 420 - 430 since there's parts of the US you can't operate in those 10 megs. Down there from what I understand, though I could be wrong, is amateur TV. The important thing is we don't lose the 430 - 440 segment because that's where a lot of activity, satellite links included, happens on 70cm. Taking away 450 - 470mhz would also essentially kill both the FRS and GMRS bands as well which, while not always hams, is regularly used by thousands of people. ~73, AC2RF Ron On Mon, Feb 21, 2011 at 6:32 PM, Nigel A.

Could we get it hauled up to ISS and kicked out the door with orbital boost engine? I guess that would be a huge permitting battle? Considering the interest in using the ISS as a launchpad for satellites and manned space craft have increased, depending on how Arissat-1 fairs it might be possible for other birds to piggy back a ride with a resupply to the ISS for a launch and with P3E being the testbed for the P5A Mars mission it might have enough leverage to go this route. I'd encourage both Peter and the rest of AMSAT-DL to at least consider inquiring about it. With that said I missed out on the opportunity to work on AO-40 as it died before I became licensed, but when I found out about AO-40 I became hopeful P3E would get launched so I could experience working a HEO for myself. ~73, AC2RF Ron ___ Sent via AMSAT-BB@amsat.org.

AO-27's schedule basically works as follows: when it turns on it transmits roughly 30 seconds of data, activates the repeater for 7 or so minutes, then another 90 seconds of data before shutting off. If it appears to be dead afterwords (ie you can't hear yourself on the bird with a 2nd radio or in full duplex) then you caught it on the tail end of the schedule.

I've been using HamSat Droid for a while now as its a nice little Sat Prediction app. There are a few other Android apps for Hams out there and many, unlike the iCrap, are free or donation ware. Some others that I use are: Amateur Radio Call Log - Self Explanatory. Just enter the call sign, signal reports, and band your operating on. Quick and simple. Compass - Best compass app out there. Not exactly a Ham or AMSAT specific app, but its very useful for getting your bearings without having to bring a compass with you to keep the load down. Also Digital mode makes getting your bearings even easier if you're not familiar with how a compass works to get your bearings. DroidSat - This is a great little app that helps you locate and identify where in the sky various satellites are including AMSATs. After you get your bearings and pass info you can locate where in the pass the bird is. Really useful if you started late in the pass or are having problems locating it. Grid Locator - Self Explanatory. Push the button and it will use the GPS to locate you and your grid square. HamSat Droid displays this as well, but this useful for when you're not doing AMSAT work like VHF contesting. Ham - May not be directly AMSAT related, but still somewhat relevant. Displays Solar and HF/VHF propagation data. Ham Radio Study - Studying for an exam? Take the practice exams for Tech, General, and Extra on the crapper! ;P IRLP Finder - Uses Google Maps to locate repeaters around you and the area you wish to connect to that are equipped with IRLP.

What you are seeing is over-charge which is normal. The battery should settle around the 9.6v mark and last a while there.

Wearing headphones and transmitting on lower power helps out too. ~73, KC2WQW On Mon, Jun 21, 2010 at 12:12 PM, ANTHONY JAPHA tjja...@earthlink.netwrote: I use 2 FT817s for portable ops, and have been disappointed in the battery performance.

I pretty much always operate low power as it is and the only indicator they give is if you hear FM noise while in SSB, unfortunately being a new ham I do not know what that sounds like.

Those settings look correct to me. I made my first sat contact on HO-68 using just a Yaesu VX-7R ht and an Arrow II handheld yagi. So long as you're homebrew antenna was constructed correctly, you're aiming for a realistic max elevation (I usually aim for 30 degrees or higher), you're tuning your downlink to compensate for the Doppler, and the sat is turned On during the pass you should be able to establish a QSO. My biggest problem with HO-68 is the scheduling. For me the sat is usually turned off during the good passes I can use. If I'm lucky I may get 1 good pass with it turned on a week. ~73, KC2WQW Ron On Fri, Jun 4, 2010 at 2:22 PM, Ng, Peter peter...@bccdc.ca wrote: Hi Alan and Everyone on the list, I have not been able to make contact with HO-68 on V/U FM voice.

[amsat-bb] Re: new to sats
Hey Jimmy, some of the easiest birds to try are AO-27, SO-50, AO-51, and HO-68. All of them are popular birds with plenty of contacts. Only thing to keep in mind is the schedules they run on. You want to make sure they're turned on and what mode they're in when making a pass. A lot of that info can be found on AMSAT.org and I've found YouTube to be a good resource for teaching you how to make your first contact on the birds with just a dual band yagi antenna and a HT or two. Best of luck working the birds! ~73, KC2WQW On Thu, May 20, 2010 at 11:09 AM, Jimmy c kc9...@centurytel.net wrote: Hello, I been reading this group. for some reson I did not think we could post to it.

[amsat-bb] AO-40 question(s)
So I'm considering putting together something that can work AO-40 and similar satellites, but everywhere I look says you need 2 radios or full duplex. Never really said why so I'm curious why its required to have 2 radios (which just seems more complex expensive) or full duplex to operate on this HEO. Couldn't I use a laptop and a data cable to control a rig like a Yaesu FT-817 to line up the Rx and Tx? ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Re: Field Day mode for AO-51
Agreed. Sure your arm gets tired after a long pass from satellites like HO-68, but half the fun is the simplicity and the other half being the challenge. I doubt I would personally get involved with L/U on LEO's like AO-51 because of the cost and complexity of having computer controlled servos to track them just for a 10 - 20 minute window that you only get once or twice a day depending on the LEO. Considering I work satellites mostly on weekends the amount of use it would get wouldn't be worth it for me. I'd be more likely to build a setup for working HEO's like AO-40 before building a setup for L/U work on LEO's due to the simplicity, larger foot print, and longer predictable window. To be honest I would use FM on AO-51 as that is the most likely usage new comers to satellites will most likely end up using. If you want to demonstrate the raw rag chewing potential of satellites then demo a HEO like AO-40. ~73, KC2WQW On Tue, May 4, 2010 at 2:30 PM, Gordon JC Pearce gordon...@gjcp.net wrote: On Tue, 2010-05-04 at 07:20 -0500, Alan P.

In the four passes I monitored last year, totaling 46 minutes, there were only 21 station heard. Half of those were on the first pass, and by the last pass on Sunday, only one plaintive station calling. Alan WA4SCA Presumably that's because very few people have L- and S-band equipment. I'm guessing that many people are - like me - put off by the prohibitive cost and requirement for overcomplicated tracking systems. Working V/U with a handheld antenna is much more fun than sitting watching a computer twiddle servos and tune the radio for you. Gordon MM0YEQ ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Field Day AO-51 configuration - another option
AO-51 is FM only the last I checked. On Tue, May 4, 2010 at 4:31 PM, Patrick STODDARD (WD9EWK/VA7EWK) amsat...@wd9ewk.net wrote: Hi! With all the talk about the possibility of an L-band uplink and/or S-band downlink on AO-51 since there will be at least 2 other V/U FM satellites available during Field Day weekend, what about sticking with the V/U frequency combination but go with something different for the 2m uplink mode? Using SSB or even CW on the 2m uplink would make AO-51 different than the other V/U satellites, yet still provide a challenge that more stations could take on than L-band or S-band - and the variety that Drew mentioned that the AO-51 group wants to provide for Field Day weekend.

Personally I just use my Arrow II hand held yagi and my Yaesu VX-7R for working satellites.

Jacob, They will work, but understand that you will be dealing with a VERY WEAK signal. In my opinion, not the best for a starter antenna. An experienced operator who knows what they are getting into, and is willing (or desiring) the extra challenge can do fine with them.

[amsat-bb] Re: Fwd: [eu-amsat] HO-68 versus AO-51
Well just something the original author needs to bear in mind is he's comparing a satellite that was launched roughly 5 months ago (ho-68) to another that was launched almost 6 years ago (AO-51) so of course there's gonna be some significant differences among them being mission objectives. HO-68 is the first Chinese AMSAT and China is going through an industrial revolution of sorts at the moment so it makes sense to make their first AMSAT as advanced as they can make it to add to their list of technological achievements. Its really comparing Apples to Oranges. Unfortunately being a new ham myself I can't share the same sentiments as the author seems to be more interested in CW then Voice/Data which appears to be really his only reason for claiming HO-68 is a superior satellite. At the moment I don't know CW and my interest in it is a passive one since I'm more interested in digital modes like PSK31. That and it doesn't help that my only dual-band vhf/uhf rig that I use for working satellites is an HT either. ~73, KC2WQW On Mon, Apr 26, 2010 at 11:14 AM, n5...@email.com wrote: Found this interesting from another mailing list. -Original Message- From: John Hackett archie.hack...@hotmail.com To: eu-am...@yahoogroups.com Sent: Sun, Apr 25, 2010 3:50 pm Subject: [eu-amsat] HO-68 versus AO-51 HO-68 v AO-51 ??. HO-68 versus AO-51 - and the university downlink only satellites - (aka the FM menagerie). In my honest opinion it's a 'no contest' scenario - with HO-68 winning hands down. The two main reasons for me making this claim are ... 1) HO-68's superior orbit. 2) It's multi-mode transponders. On a typical European pass an HO-68 orbit has a footprint the covers from Spain in the west to India in the east, Norway in the north to Sudan in the south ... and all points in between. Whereas AO-51 is FM only ... HO-68 has transponders for CW, SSB as well as FM. HO-68 is (IMHO) easier to operate due to it needing less power to get into the transponders, albeit, to really take advantage of that, a knowledge of CW is required, which *STILL* shows it's great advantage as weak signal mode. When all else fails ... switch to CW. Igor, RW3XL has been operating cross-satellite with HO-68 to VO-52 and HO-68 to AO-7 ... keying the up down buttons for CW since his keyer is on the blink. For those wanting to learn, the 200mW beacon sends *SLOW* morse and it's copyable on a piece of wet string wrapped round a rusty six inch nail. I've proved this over and over on HO-68 at the beginning of passes when the elevation is under 20 degrees and a SSB just can't make it - switch to CW - Q5 copy - (Domenico,I8CVS will endorse that). I believe that HO-68 is becoming the experienced 'operator's' satellite while AO-51 will remain the platform for the potential newcomer ... where they can QRM eachother to their heart's content ... more power Egon ... MORE POWER !!! ... (with due apologies to the Hollywood film 'Frankenstein'). For me at least, HO-68 has brought the fun back into amateur satellite operating, particularly on CW ... akin to RS-10, the most popular satellite ever - (judged by the amount of users) - after the veritable old AO-7. While everyone is entitled to his or her opinion, operating FM on a satellite is about as much fun for me as watching paint dry and is, in my opinion, the worst possible way to introduce a potential newcomer to amateur satellites. My EU-Amsat co-founder, SV1BSX (SK) first used the word 'zoo' to describe the AO-51 standard of operating. There ought to be a sign on the microphone ...
