I’ve verified that there is 12v from the radio on the RF output. I’ve also verified that the preamp is not working. Strange as it was working fine in my EME system but I was powering it with a separate line controlled by a sequencer. I wonder if there is some sort of choke or something that is added or removed when powered via the coax. I also have no inline lighting arrestors and am not using an amp between the radio and antenna. Rick, W2JAZ -- Sent from Gmail Mobile

Satpc 32 question on tracking
by Bruce 04 Jul '20

04 Jul '20

Got tracking working with the FoxDelta ST USB version this past weekend. Doppler correction is working on the IC-9100. When I ask it to track SO-50, it is supposed to go to 175.8 azimuth and 1 elevation but instead it goes to 356 azimuth and 138 elevation. I setup the FoxDelta for 180 elevation max and 450 azimuth max. You would think there is an issue with the FoxDelta. But.... If I switch to PO-101, it moves exactly to its location perfectly. I switch back to SO-50 and it goes to a whacky az/el. Have not turned off or touched either the Yaesu controller or FoxDelta, RS-44 coming over, tracked it perfectly. Again not touching anything, just set it for AO-7. Was supposed to be AZ 337.5 and EL 5.8 but rotor went to AZ 158 and EL 176. The ServerDX says target 159az/178el and actual 159az/178el. Any suggestions? It has done this with several satellites. Even if I turn off the Yaesu controller and the FoxDelta and turn them back on, it goes to the whacky location for SO-50 and perfectly to PO-101. On the Rotor page, there is a park location of 10 az and 180 el. Correction has zeroes in both az/el. Park automatically after pass is off. ServerDX shows target Scratching my head on this one. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2020 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 athttp://www.amsatnet.com Podcast athttp://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitterhttp://www.twitter.com/amsat

Twitter Rove Announcements
by Paul Overn 03 Jul '20

03 Jul '20

Hey guys, having trouble keeping up with all the roves and two twitter accounts to manage the GridmasterHeat and the AMSAT duties. So asking if you follow my @KE0PBR account for roving announcements, please change to follow the @gridmasterheat account for that information. Also if you are announcing a rove on twitter, please tag the @Gridmasterheat account. So I can post on the AMSAT page and tag people that need the grid(s) If you are announcing a rove in the BB, no change needed. And if you want to alert me by email please do, that email is KE0PBR at gmail dot com. This really won't be much of a change for many, seems people already made this change. :-) -- KE0PBR Paul Overn AMSAT Ambassador Twitter: @KE0PBR Website: KE0PBR.Wordpress.com

Satellite Roving Trip to EN67/EN56/EN55/EN54 July 8th to 10, 11? - AA5UK
by Adrian Engele 03 Jul '20

03 Jul '20

Hello Satellite Operators. I am taking a few days off next week since I have not had a vacation day since December 2019. Starting to get a little cabin fever from all this working at home bit.My GF has given me the thumbs up to go do a satellite rover trip. I looked at the map and decided to head North, as this seems to be the safest place to be during CV-19. This will be my first formal CONUS Satellite Rove! I have operated from KH6,VP5, ZF and EN61/EN53. I will be heading to EN67 Copper Harbor and plan on working my way back home(EN61 - Chicago) via EN56/EN55/EN54, maybe EN53/EN61. I plan to be on the road from July 8 to 10th, maybe 11th? Operations will depend on weather which look spotty at times on Wunderground. I have no particular passes planned at this stage best to look for daily updates via Twitter @AA5UK or here at AMSAT-BB. I will try some FM passes (depending on the usual goat rodeo and civility) with focus more on the linear satellites. I will announce my RX or TX frequencies via Twitter.Please note this is a vacation trip and I will be doing some hiking, drone flying and photography. Follow my travels on APRS SSID: AA5UK-9 More to come. Stay tuned! 73, Adrian AA5UK

Ssb2000 preamp power
by Richard Lawn 03 Jul '20

03 Jul '20

I have an older orange case SSB2000 model preamp. I used to use it for EME but replaced it and now want to use it in another installation for satellites. I do not however want to power it separately and want to send power down coax with ft847. This does not seem to work and I’m wondering if I need to make some sort of internal change to the preamp. The manual suggests I can power it through the coax. Any thoughts? Rick, W2JAZ -- Sent from Gmail Mobile

LVB Tracker firmware
by Ed Krome 03 Jul '20

03 Jul '20

Hi all I have 2 G6LVB Trackers. One has firmware v. 0.7 and the other has v. 0.906. I would like to upgrade the older unit but cannot find the required files. Howard’s site has a link that fails and there is no link on AMSAT-UK. Can someone please point me to the latest? Thanks and 73, Ed Krome K9EK Sent from my iPhone

Re: [amsat-bb] 12th Annual 13 Colonies Special Event
by Stephan Greene 03 Jul '20

03 Jul '20

Speaking of 13 Colonies, I'll be representing Virginia as "K2B" from FM18, and possibly FM19 or FM08 on 7/3 and 7/4 (TBD). I plan to prioritize the linear satellites but will give FM a try if the pass is not too crazy. I expect to be on late afternoon/evenings on the work days and more frequently on July 3 and 4. (July 5 looks to have a lot of family activity, so "staycation mode"). I will try to announce plans on Twitter (hashtags #13Colonies #amsat #K2B). Likely QRG will be 5kHz ABOVE passband center (+/- QRM), computer-controlled. On AO-7, around 145.438-.440 unless there is a rover operating (I'll move up). More info on the event at http://13colonies.us (note new URL from prior years). This will be my first year representing 13 Colonies instead of chasing the stations on HF. All QSL (they have a very nice design for 2020) is through each state's QSL manager (link from 13 Colonies or each call's qrz.com page). If you need my grid or Virginia on LOTW, please tell me, and I'll switch to my own call so we can log it. If you are in one of the 13 Colonies states, it's not too late to contact your state coordinator and join the fun! 73 Steve KS1G FM18 --------- Forwarded message ---------- From: Cal Spreitzer <n3cal(a)md.metrocast.net> To: <amsat-bb(a)amsat.org> Cc: Bcc: Date: Sat, 27 Jun 2020 10:19:12 -0400 Subject: [amsat-bb] 12th Annual 13 Colonies Special Event The 12th Annual 13 Colonies Special Event (Independence Week Celebration) starts Wednesday, July 1, 2020 -1300 UTC and runs through Wednesday, July 8, 2020 (0400 UTC) This will be my second year representing Maryland as "K2F" from FM18.
