[amsat-bb] Re: AO-51 S-band // WIFI USB dongle as receiver?
Hi Paul, Well, interesting thought. While the 2.4 gHz Wi-Fi and 13cm Ham bands do overlap, the modulation used by Wi-Fi signals and AO-51 are very very different. AO-51's narrow band FM downlink is going to be totally ignored by the frequency-hopping spread spectrum receive demodulator in the Wi-Fi dongle. I say that with some question, however, in that some Wi-Fi equipment is capable of some interesting RF detection and interference analysis, and might be hacked into some sort of digital receiver. The trick would be getting the right dongle and software, and then customizing the detection algorithm and decoder. Could be an interesting project for someone with the right skills and access to what is probably a very proprietary interface. But straight out of the box, sorry, no. Your best bet is to hunt around for an MMDS downconverter (I have a Drake 2880). Most are quite inexpensive, and are easily converted for Ham use. Saddle that up to your antenna and rig, and you'll have a setup that's probably overkill for AO-51.

Hello to the AMSAT brain trust. I am new to satellites and have a new person question: Is there any way to utilize a WIFI (2.4 GHZ, 13cm) USB dongle (with SMA ant. port) into a gain antenna, and successfully receive the S-band downlink from AO-51? This is a 13cm transceiver, but I suspect the answer is no. I already have a 24db gain dish, so I thought I would ask. Outside of WIFI, is there anything useful I can do with this dongle? The more conventional units (transverters, receivers, etc.) are a bit spendy for me right now. thanks. paul ac0z ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Re: Android satellite tracking
Wayne, When you are on the page of predictions, click on one and it will display a circle with a line that shows the satellite's path from AOS to LOS. During the pass there is a dot that travels along the line depicting the satellite's location. So it gives a little better idea where it is in relation to you. It's not exactly what you're looking for, but it does help.

[amsat-bb] AO-27 Off Frequency?
Hi, The last two AO27 passes I have worked over the past two days that come up from my SE appearing to be about 5kHz off frequency (high). I have to monitor 436.810 to receive the signal clearly at AOS. I would usually start at .805, 10kHz above the transmit frequency of 436.795. On the passes that favor my west all appears to be normal. Am I the only one that has noticed this? 73! Zack KD8KSN ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Possible delay for mode change Re: AO-51 schedule for February, March 2011
It is very possible that the mode change on Feb 27 (to V/S) will be postponed. The satellite is still seeing periods of eclipse due to sun angle, etc. At this point we need full sun to operate in S-band, so the mode change is dependant upon telemetry showing that we are good to go. Things might work out, but my hunch is that we'll have to postpone a day or two.

[amsat-bb] ND9M/MM Ops: 27 Feb
We're progressing toward W6-land and should be there this coming Wednesday. North America is solidly within many footprints now, and a lot of contacts have been made. It's also surprising to me that several of the passes I've been on have had no other signals even though the footprint covered well into North America and I heard my downlinks quite easily. The seas have calmed considerably, but the winds have brought the wind chill down into the 30s. That makes for some mighty cold passes! Here's my planned op sked and the expected grid(s) for tomorrow, 27 Feb: FO29 - 27/1106Z - CM15 or CM25, possibly both during the same pass VO52 - 27/1745Z - CM25 AO27 - 27/2107Z - CM35 VO52 - 28/0305Z - Probably CM45 AO7 - 28/0324Z - Probably CM45 FO29 - 28/1013Z - CM54 These passes are during my business hours. I'll make them if I can. AO27 - 27/2246Z - CM35 - Approximate turn on time AO7 - 27/2343Z - CM35 - If in Mode B FO29 - 28/0004Z - CM35 AO51 - 28/0013Z - CM35 - will miss the first few minutes to be on FO29 AO7 - 28/0130Z - CM35 - This is a likely one, but I can't be sure. FO29 - 28/0149Z - CM35 - This is also a likely pass to make. Here's a maybe pass: VO52 - 27/1611Z - CM25 - It'll be low (4 degrees) and early here, which is why it's a maybe...
