Has anyone made a portable rotator AZ/EL using a rasberry. I see sat trackers but no mention of antenna control? I would like to pursue something as a learning project and drive my arrow yagi . Jim KI6WJ

WD9EWK @ DM22/DM32 on Saturday (28 December 2019)
by Patrick STODDARD (WD9EWK/VA7EWK) 28 Dec '19

28 Dec '19

Hi! I plan on making a quick trip to the DM22/DM32 grid boundary for a few hours tomorrow (Saturday, 28 December 2019). This location is east of Yuma in southwestern Arizona, near the I-8 freeway. I should be out there for the AO-91 and AO-92 passes starting after 1730 UTC for a few hours, and might be out there for one or two of the XW-2A passes before that time. I know there will be some overlapping of the AO-91 and AO-92 pass times tomorrow, and will try to work the AO-91 passes before switching over to AO-92. My drive out to the DM22/DM32 grid boundary should show up on APRS as WD9EWK-9, on sites like: http://aprs.fi/WD9EWK-9 Updates during my time out there will be posted on my @WD9EWK Twitter feed. If you don't use Twitter, you can see these updates in a web browser at: http://twitter.com/WD9EWK QSOs will be uploaded to Logbook of the World after the trip. If you would like to receive a QSL card for any contacts made out there, please e-mail me directly with the QSO details. No need to first send me your QSL card and/or an SASE. If you're in my log, I will be happy to send you a WD9EWK DM22/DM32 QSL card. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK or http://twitter.com/WD9EWK

CAS-6 Missing From Keplerian Data?
by Hasan al-Basri 27 Dec '19

27 Dec '19

Since the data was restored this morning, I no longer see CAS-6 in the list and it has dropped out of my tracking program. Is there now another name? The good news is that a JK station reports TLM from CAS-6 at 1130z this morning. Hasan

It uses a homebrew tracker that is controlled by hamlib. There is also https://www.portablerotation.com/ for an off-the-shelf solution. I believe this can also be controlled via hamlib (and thus a raspberry pi running GPredict should be able to control it). --Roy K3RLD

SatPC32 now has spectrum scope for IC-9700
by Mark L. Hammond 27 Dec '19

27 Dec '19

Hi 9700 Owners and Users-- Erich DK1TB has graciously added a spectrum scope window for the IC-9700. If you read his instructions on this page, and get the new SatPC32 download---you'll have the option of doing so. You'll have to update your SatPC32 install with the currently available package. http://www.dk1tb.de/indexeng.htm Only point to make very clear--you'll need both an "old" style Icom CAT control interface/cable for radio control AND the USB cable from the radio to the computer; the USB comport is used for the spectrum display only in this configuration, and the CAT cable is used for radio control. And yes--you can click on the spectrum and the radio frequency follows :) Read it all carefully--it worked first shot here. Thanks, Erich!! 73-- Mark L. Hammond [N8MH]

VAC and WIN10 upgrades
by Alan 27 Dec '19

27 Dec '19

Some background first. Flex Radio uses a version of Virtual Audio Cable (VAC) called DAX with their current rigs. In the past, almost every WIN10 upgrade trashed the DAX installation which then needed to be laboriously manually repaired. Recently, that issue has been reported resolved. Has anybody had any issues with WIN10 upgrades with general VAC installed, especially recently? I have heard of one case, but not recently. I know there are some other equivalent packages, but for operational reasons need to stick with VAC. 73, Alan WA4SCA ----------------------------------- Freedom is the freedom to say that two plus two make four.

M2 LEO pack discount via AMSAT store
by Devin L. Ganger 27 Dec '19

27 Dec '19

All, I've seen mentioned on the list before that there is a "substantial" discount for the M2 LEO pack via the AMSAT store for members. I'm looking at the page now and I'm not seeing a very big discount. However, I also notice that my user account shows my membership having expired in 2019 and not being current despite having a past order for 2019, so I'm wondering if there is an error in my membership status that would affect the price that I am seeing. The other option, of course is that I simply misunderstand the specifics of the discount. :) Thanks in advance, -- Devin L.
