Potential 23cm FM transmitter
by Brad Brooks 01 Feb '18

01 Feb '18

For those who receive the DKARS magazine, there is a very interesting article. The transceiver described is for ATV, but it looks like like it will tune to the AO-92 uplink frequency. Seems to put out 400mw FM out. I am not able to take time now to review deeper (stealing away from work) but I look forward to parsing through the schematic/links this weekend. I am forwarding this notice for anyone who will be able to get there sooner. I think there is some potential here, and I would like to know other’ opinions.

Please record our ARISS contact Monday February 5th!
by John Brier 31 Jan '18

31 Jan '18

Hi amsat-bb! I am leading the ham team for an ARISS contact here in Raleigh and we are using my callsign for the contact. I would appreciate any audio recordings you can make of the pass, especially the part where Astronaut Scott Tingle hopefully says my callsign :-) I will be recording on both our primary and backup stations but you never know if we'll get a fade in the beginning. They will be on the Kenwood D710E in the service module with 50 watts so it should be a good signal. Moore Square AIG/GT Magnet School, Raleigh, NC, direct via KG4AKV The ISS callsign is presently scheduled to be NA1SS (***) The scheduled astronaut is Scott Tingle KG5NZA (***) Contact is a go for: Mon 2018-02-05 18:32:06 UTC 25 deg (***) FWIW, AFAIK there is no livestreaming planned. If there is I'll let people know. 73, John Brier KG4AKV

I'm new to this list and new to satellites also, so I would appreciate some help. Is there anyone out there who uses a Fox Delta ST3 trackbox and would be able to give me advice on a problem I am having with it? John VA7XB

Android - apps similar to Heavens-Above?
by Philip Jenkins 30 Jan '18

30 Jan '18

Hi all I bought a new Android tablet on Saturday - Version 7.0, Nougat. AMSATDroid seems to work fine on it, other than displaying the date as "000001 29, 2018" On the tablet, I did a Google Play Store search for Heavens-Above (which runs great on my smartphone, which is running some flavor of Android 4.x) and Heavens-Above didn't show up in the store...which I thought "okay, that's strange". So tonight I went to the Heavens-Above website, thinking I would download the Android app from there. Google Play Store pops up with Heavens-Above app but I'm getting the message "Your device is not compatible with this version". So, what I'm looking for - assuming that the Heavens-Above app won't be updated - is a similar app which will run under 7.0. How about Satellite Tracker from Tythatguy. or Satellite Tracker by Vito Technology (reading the reviews, the latter doesn't seem to be as useful as Heavens-Above or Tythatguy's version). Any others you might recommend? Comments? Suggestions? Any way to make 7.0 backwardly compatible? <grin> Philip N4HF

XW2A satellite?
by christy hunter 30 Jan '18

30 Jan '18

there is a regular group that uses these XW sats, including 2A, in the early am on the western passes. The evening passes I have noticed minimal use. 73 Christy, KB6LTY ---------------- I've been on a few times by myself. I think sat ops forget about it at times.

Re: [amsat-bb] EO-88

I’ll also try to do a better job listening for it. It is one of only a couple of birds that I haven’t made a QSO. Seems like the good passes only come over pretty late at night. FS-3 is the other bird, but I am now prepared to work it when the orbits cycle back around here in a week or so. Red KC4LE
