Possible CO96 Operations
by B J 29 Aug '12

29 Aug '12

I'll be flying to CO96 Wednesday of next week and will be returning on Friday. If time permits, I will try to be on AO-27 and SO-50 as I'll be taking my FT-817ND and my Arrow Yagi.. FO-29 is also a possibility but only in half-duplex. I will try to work any passes from about 1800 - 2100 UTC Wednesday and Friday but I won't try on Thursday as I have a prior commitment that day. If I do try to work an FO-29 pass, I'll be operating my radio manually, transmitting on 145.930 MHz and tuning my downlink around 435.855. Longer calls would be appreciated as I might not hear your callsign and/or grid square right away. Because of the reason for my trip, I can't guarantee that I will work any passes. I plan on going to CO96 at least once more later this year so I might have a better opportunity then. 73s Bernhard VA6BMJ @ DO33FL

Great write-up, Tom. Clever. Looking forward to trying it sometime (all I need is more time..hi hi)! 73, Mark N8MH At 04:44 PM 8/29/2012 -0500, Thomas Doyle wrote: >I have had success with the FUNcube - SatPC32 project.

Duchifat-1 a 145.825 MHz APRS CubeSat
by Trevor . 29 Aug '12

29 Aug '12

Duchifat-1 is an experimental and educational spacecraft developed and built by young Israeli students at the Space Laboratory of the Herzliya Science Centre (HSC). It features APRS on 145.825 MHz and also a UHF/VHF BSPK transceiver that can operate as a FM to DSB transponder. See http://www.uk.amsat.org/?p=9982 73 Trevor M5AKA

FUNcube <==> SatPC32

I have had success with the FUNcube - SatPC32 project. I finally have a combination of stuff that works for me. Here is a collection of notes on what works in my shack. Like most things there are lots of different ways of doing this. I make no claim that this is the best. Who knows it might be the worst. www.tomdoyle.org/FUNcube-SatPC32 73 W9KE Tom Doyle

Hello everyone. I have wrote an email to Elk antenna's to see if they would send the lp 144/440 to Scotland. Have emailed them twice with no response. Email I sent to was rgaschk at astound.net from the website?. If this is wrong or outdated can somebody give me the correct email please. Cheers Kev mm0kjg

Software must have list

So my 4 yr old XP shack computer is in critical care right now, and I have a new quad core Win 7 HP that I'm setting up today. So far I've downloaded and installed: SatPC32 (still working on the speech error problem) MixW 3 HDR 5.sumthing Spectravue next up is WSJT What must have ham radio programs, especially satellite/vhf/uhf, do you have and recommend? 73, Drew KO4MA
