Hi Bob<br><br>It never had a satelite like PCSAT. Yesterday I was able to repeat my packet using 100mW with THD7 + AL-800. Elevation was 5 degree. Is there a PCSAT3 in the future?<br><br>73, Francisco<br>PT2TD<br><br>====================================================

ANDE and RAFT APRS satellites are operatonal. There is a local<br>TV clip now on<br>the web page where the students discuss their satellite<br>projects. See<br><a href="http://www.ew.usna.edu/~bruninga/ande-raft-ops.html">
http://www.ew.usna.edu/~bruninga/ande-raft-ops.html</a><br><br>Both signals are weak and require a beam and high elevations to<br>hear them. As of this time, RAFT speech is enabled for special<br>testing only in accordance with the User Service Agreement:
<br><a href="http://www.ew.usna.edu/~bruninga/ande/ANDEcontract.txt">http://www.ew.usna.edu/~bruninga/ande/ANDEcontract.txt</a><br><br>During a 58 degrees max elevation pass, at about 45 degrees<br>elevation, PA3GUO reports a successful voice packet via RAFT.
<br>The MP3 file is on the ANDE-RAFT-OPS web page above. A high<br>elevation pass is usually required.<br><br>PLEASE NOTE! RAFT is underpowered for this voice mission, and<br>so this capability should only be used by special demo stations
<br>and for special events or tests. The downlink is very weak and<br>needs a beam and a high elevation pass to hear it. DO NOT<br>TRANSMIT A VOICE PACKET IF YOU CANNOT HEAR THE DOWNLINK. You<br>must adhere to the user service agreement above to use this
<br>capability.<br><br>When ACTIVATED, RAFT will speak an APRS formatted MESSAGE<br>addressed to the callsign of TALK. This APRS Message packet was<br>Transmitted by PA3GUO:<br><br>> PA3GUO-8>APRS,RAFT*::TALK :henk says hello
<br><br>First the packet is digipeated (lets you know it received it).<br>Then (up to 10 seconds later), it should SPEAK the packet. In<br>this case RAFT spoke:<br><br>> "PA3GUO" + "says" + "henk says hello"
<br><br>Although the Speech synthesizer is ENABLED, it is normally OFF.<br>To use it, someone in the footprint has to activate the voice<br>module with a CONNECT REQUEST to "RAFT". On hearing a connect<br>request, (the connecting station can do nothing else), RAFT
<br>responds in voice with "Welcome to TextSpeak". At that point,<br>RAFT will speak any APRS formatted MESSAGES from anyone to TALK.<br>Again, notice that if you see the successfully DIGIPEATED<br>packet, then it will speak it, although there might be up to a
<br>10 second delay. If you see such a successful APRS MESSGE to<br>TALK digipeated, then everyone should hold off until it gets a<br>chance to speak it.<br><br>Notice the APRS MESSAGE format carefully. The callsign TALK is
<br>bracketed with colons and is padded to 9 characters with 5<br>spaces on the end.<br><br>Oh, This speech was enabled with simply the connection of an off<br>the shelf $200 text-to-speech module connected to the serial<br>
port of the spaeccraft KPC3+ TNC. Kantronics made a slight<br>software mode to replace the normal packet header with "CALLSIGN<br>SAYS" before the packet is sent out the serial port.<br>With this mod, you can use a radio, TNC and this voice module to
<br>create "voice at a distance"... But the high cost of the voice<br>module will probably prohibit much terrestrial applications..<br><br>Bob Bruninga, WB4APR<br>US Naval Academy Satellite Lab.<br><br><br><br>
