RX only satellite?
by James Duffey 07 Feb '07

07 Feb '07

It would be interesting to look at the NCDXCC HF beacons from space to get an idea of ionospheric absorption. These have predictable times and variable predictable power levels, so path losses can be easily calculated. Monitoring the 10M frequency at 28.200 might provide useful information for future Mode A applications. With beacons all around the world, broadcasting every 3 minutes at known power levels, a 28.2 MHz receiver could provide a wealth of information. The beacons ID themselves, so data analysis should be easy; all that would be required is some sort of time tagging. I suspect that the satellite would never be out of range of a beacon. How much data storage is available? I need to calculate how much data you would need to obtain. It would be interesting to launch these satellites at various points in the solar cycle. - Duffey KK6MC/5

RAFT in Packet-Voice mode
by Robert Bruninga 06 Feb '07

06 Feb '07

Henk, PA3GUO, reports that he has just -enabled- RAFT VOICE mode. Enabled, this means that any station may TURN ON voice mode over his country with a single CONNECT RAFT packet. The voice synthesizer will remain on for 90 seconds. Only the CONNECT packet is required of that station. After his connect packet brings up RAFT, then he can fore a disconnect so he can try an APRS MESSAGE to TALK. Once the VOICE synthesizer is on, then anyone can send a UI APRS formatted MESSAGE to the callsign of "TALK" and RAFT will speak it (if it decodes it)... RAFT is very weak and hard to hear except on HIGH overhead passes, even with beams. Please do NOT attempt to turn on RAFT or to send TALK messages if you cannot hear it. You may be QRMing other stations. Thanks Bob Bruninga, WB4APR US Naval Academy Satellite Lab

It will be recoverd one year later. Hi Bob. I guess this is attached to the ISS so no oportunity to have attitude control. OK, Long time in orbit so lots of data. How about one or more of the cheap USB memory sticks for storage? 1GB+ is small and cheap these days. To interface the USB to the real world you can use an interface chip with PIC microcontroller. I'm sure that would normally be a wholelot of design all by itself, except you can buy the USB intefaced to a PIC16F877 off the shelf for about $50 limited driver software included _http://www.dlpdesign.com/usb/dlp-2232pbv15.pdf_ (http://www.dlpdesign.com/usb/dlp-2232pbv15.pdf) That gives you 16 I/O lines and some A-D conversion to play with. As for payloads? Well spectrum monitoring is good but GPS data to give the location would be an advantage so you know where you are. Bands to monitor. 2.4 is the most controversial, but the proposed uplink band of 5.6G would give valuable insight for future projects. Or, one of the new power to voltage converters from Analog Devices. Monitoring the radar fence output or other High radar signals could be interesting. Or camera that can take pics on your command. - I can almost see the picture of your QTH on the wall of your office. Taken on a clear day when you know the lens is pointing in the right direction. 73 David G0MRF www.sseti.net

AO-51 status
by Bill Goff 06 Feb '07

06 Feb '07

I've been interested attempting to work thru this satellite for several days beginning 1/31 without much luck. One each occasion I've not heard the beacon at all nor heard any other qso's. I've used the amsat path predictions and online tracking so I'm sure I'm listening at the correct times. I'm using a colinear vertical about 20' up at the QTH, so I think I've got enough antenna to at least hear the satellite. Does anyone here know it the software update is still in process? Is the satellite not in operation now? Bill KI6DJ

It would appear that her opportunities to operate may be somewhat restricted in the future. Also, it is coming up for renewal in April. Alan WA4SCA

I downloaded the latest version of Nova for Windows, as I switched shack computers, but on the new version I cannot find SO50 listed in the satellite list. Where is it-what I am doing wrong? 73s John W5TD ____________________________________________________________________________________ Need Mail bonding? Go to the Yahoo!

Fwd: ANSR-35 Launch Announcement
by Patrick STODDARD (WD9EWK/VA7EWK) 05 Feb '07

05 Feb '07

Hi! If you are in the southwestern USA or northwestern Mexico, here is an opportunity to test a satellite ground station by working the cross- band repeater on this balloon. Transmit on 2m, receive on 70cm, but without the Doppler shift on the downlink signals. Maps with the approximate coverage area of the repeater at various altitudes can be seen at: http://balloon.wd9ewk.net/ Previous balloon flights by this group have had QSOs through the repeater spanning over 600 miles/1000km. Launches are usually around 9am local time (1600 UTC), but can vary depending on weather conditions and launch team readiness. The launch sites are in central Arizona, south of Phoenix. More information about this group is at: http://www.ansr.org/ http://www.kd7lmo.net/ansr/ansr.html and their e-mail list is at: http://groups.yahoo.com/group/ballooning/ 73!
