But SO-50 needs an initial activation with 74 Hz tone and further access with 67 Hz tone, while AO-27 does not need any of these. Pass timings and directions will be different. Agreed that at some point of time they may overlap and SO-50 could work if someone has already activated it with 74 Hz tone. 73 Jon, VU2JO On Mon, Nov 11, 2024 at 10:51 AM John Antonuk - AL7ID via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > I got nothing here in Alaska / BP64 > > 73, > > John Antonuk > > AL7ID(a)yahoo.com > > > > > On Sunday, November 10, 2024 at 07:55:53 PM AKST, JOHN GEIGER via AMSAT-BB > <amsat-bb(a)amsat.org> wrote: > > > I see some reports on the Satellite Status page for AO27.

I see some reports on the Satellite Status page for AO27. Is this satellite really back on again, or might these stations be mistaking SO50 for AO27 since they share the same frequencies? 73 John AF5CC Sent using {0}

From today 11.50 UTC it will be the* SSTV experiment on 145.800 MHz *( https://x.com/ARISS_Intl/status/1855620773123170722), up to 18th November 2024. There will be pauses for scheduled school contacts. Usual APRS was on *145.825 MHz* (https://www.ariss.org/current-status-of-iss-stations.html). But now that is: *STATUS* - *Misc**onfigured, *as the same Service Module radio is to be used for SSTV experiments. 73 Jon, VU2JO On Mon, Nov 11, 2024 at 7:46 AM christy via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > I just confirmed.

If you've got a 3D printer (or a friend who has one), put in a duplexer (2m/70cm) split, and use my 3-D printed version of AA2TX's 70cm Parasitic Lindenblad. It was published in the AMSAT Journal (Sep/Oct 2020). The STL files needed for printing are here: http://www.n0zgo.net/3d-lindenblad/ I have used it with great success on the RS-44 downlink, as well as an uplink antenna. I have a homebrew LNA in line with the antenna. http://www.n0zgo.net/homebrew/70cm_lna/IMG_20201025_185513831.jpg (I should write that latter one up -- someday) 73, --- Zach N0ZGO

A year a two ago I bought the materials to build a turnstile moxon pair as described by L.B. Cebik, W4RNL, in QST. I never got around building it, but it seems to me that they could be interesting too for an attic mounted alternative. https://sat.fg8oj.com/images/VHFUHFSatelite.pdf If anyone has experience with these, I'd love to hear about it. 73, --Alex KR1ST

If the LEO pack is too long or awkward to fit in your attic, you could try this one: http://wb5rmg.zfxinc.net/k5oe/Texas_Potato_Masher_2.html With a youtube video here: https://www.youtube.com/watch?v=VgKRDHASoio&ab_channel=TheRadioAmateurSatel… It was also published in the AMSAT Journal many years ago. 73, Terry Osborne ZL2BAC
