ANDE: not heared on Dec 25
by Henk, PA3GUO 25 Dec '07

25 Dec '07

Seems ANDE hasn't been heared anymore on Dec 25th. Last packet received would be dated 2007/12/24 at 21:14:13 utc. Just in case, I took a copy of findu.com, to capture the last packets received on the 145.825 MHz downlink of ANDE (all Dec 24th): http://home.vianetworks.nl/users/hamoen/pa3guo/ande_findu_last.mht >From that I would derive: Last digipeat: W6MSU 20071224211413 : W6MSU]APRS,ANDE-1*,qAO,W6MSU-3:=3803.21NS12121.62W& Last telemetry: N0AN 20071224194836 : ANDE-1]BEACON,qAo,N0AN:T#007,138,047,049,046,214,11100001,000 Last beacon: JA6PL 20071224205458 : ANDE-1]APRS1,SGATE,qAo,JA6PL::BLN1ANDE :ANDE-1 only wakes up 1 of evry 15s for users. Pse conserve. Did anyone receive a packet later ? Henk, PA3GUO http://www.qsl.net/pa3guo

Re: Oscar 9 Re-entry
by Clive Wallis 25 Dec '07

25 Dec '07

Hi, I was very interested in Jeff's and Dave's comments. Was there more than one 'Chicken Little' competition? AMSAT-UK took over the competition which was originally started by UoS. The winner was Geoff G3ENY, who sadly is no longer with us. I spent quite a lot of time attempting to predict the 'burn-up'of OSCAR-9 and Salyut7. I'll put together what information I can find, and post it here in a few days time. I would be very interested whether any one can find any references in the AMSAT Journal or elsewhere, other than in OSCAR News, which I already have. Seasonal best wishes to all. -- 73 Clive G3CWV Hitchin, North Hertfordshire, UK.

Amateur Satellite Receive Anennas
by Dave Guimont 24 Dec '07

24 Dec '07

I see a lot of discussion on here about the difficulty of receiving our present low orbit satellites... Admittedly, I have not tried other than AO7, AO51, VO52 and SO50... AO51 requires not much more than a "wet noodle" for both up and down link, so relate your sig strengths (both up and down) with relation to it, and I can help...Also tell me if your problem is up or down... Can they hear you? or cannot you hear them... It would sort of give me a guide as to the capabilities of both your receive and xmit systems. There are many factors that relate to the above questions, but let us start there. And many factors that can lead to success... Tell me the bird you are having difficulties on, and I will try it... 73, Dave, WB6LLO dguimon1(a)san.rr.com Disagree: I learn.... Pulling for P3E...

OLPC
by Robert McGwier 24 Dec '07

24 Dec '07

This is sent with my OLPC. What a great idea this project is. It goes to show what can be acccomplished ny dedicated individuals, something familiar to a lot of people in these two groups. The thing does appear to have sufficient horsepower to do some DSP. I would like to think we can make several things available to this project. For example, I think a tunable HF receiver for shortwave AM broadcast is easiy achievable for very modest cost. Further out, I would to see the use of this machine and OFDM skywave to provide WAN capability to large areas of the world without such capability. At least one Negroponte clearly has heart and vision. Happy holidays and I hope everyone is looking forward to 2008 with as much anticipation as I am. Bob

Hi all, Does anyone have any experience making a RigExpert "Tiny" Model: TTL-I-1 for the Yaesu FT-100, FT-817, FT-857, FT-897 work with a Yaesu FT-847 or Kenwood TS-790. I know I will have to rewire some plugs or make adaptor wires to match the radio's but I was hoping not to re-invent the wheel if someone already figured it out. The people at RigExpert say they don't make a version for the FT-847. RoD KD0XX

Testing beams
by Andrew Rich 24 Dec '07

24 Dec '07

I have a little signal source of 10mw on 434 MHz I would like to use it as a source to dest the directivity of some antenna projects. I am finding it it too loud How can I dampen it down besides drive it 3 kms that way ? I spose I really need to go for a drive to the country I really wanted to test here. ---------------------------------------------------------------------------- Andrew Rich VK4TEC vk4tec(a)people.net.au http://www.tech-software.net
