Could one set the transmitter and >receiver on the nominal frequency and still copy transmit and receive small >files and APRS position reports? It all depends on pass band widths. If the 2 m receiver is sufficiently wide to allow an off frequency signal into the pass band, then you don't need to correct on the uplink. Fortunately, the pacsat receivers are sufficiently wide. 2 m Doppler shift is around 3 kHz, while 70 cm Doppler can be around 10 kHz. So, you must correct for YOUR receive on the downlink. Since Doppler can be 10 kHz high at the beginning of the pass, and 10 kHz low at LOS, that is a 20 kHz spread. Since a properly deviating 9k6 signal will occupy 20 kHz of bandwidth, your receiver must pass more than 30 kHz of signal to capture the coherence. What is the bandwidth selectivity of your rig on 70 cm? In practice, it is a good idea to correct both for uplink and downlink on the pacsats. You could program non-standard splits in your rig, and just tune frequency pairs as the pass progresses. On 2 meters, 5 khz low at the beginning of the pass, right on frequency at the middle, and 5 kHz high towards LOS will suffice, if your rig will only tune in 5 kHz steps. Here is a suggested table of frequencies to program into your dual band rig for UO-22. Downlnk - Uplink _________________ 435.130 - 145.895 435.125 - 145.900 435.120 - 145.900 Mid Pass 435.115 - 145.900 435.110 - 145.905 I hope this helps a little. 73, Mike __\/__ | . / ^ _ \ . | |\| (o)(o) |/| ^ --- * -----------------.OOOo--oo--oOOO.------------------- * ||| | | * Mike Gilchrist - KF4FDJ .....

I have been doing a lot of research on remote-controlling the TMD700 Kenwood radios. The bulk of my work is posted at http://www.netcom.com/~jimgill/tmd700a.htm , and I found a few more "must-have" APRS mode nuggets this morning. Send these to the serial port at 9600,8,n,1 while in APRS mode. DTX 0 manual packet tx DTX 1 PTT packet tx DTX 2 AUTO packet tx BCN 0 turns off beaconing if on AUTO BCN 1 either turns on beaconing if in AUTO or BCN 1 **sends a beacon when in manual mode!** then returns to BCN 0. Fabulous stuff for your remote control software projects. Still have the problem though of DCD sense to figure out when in automatic mode. More on that later. I will continue to add research updates to my website, comments/suggestions welcome direct or by sig.

I can't find a way to program a single memory in the TMD700 with a VHF transmit and a UHF receive. Otherwise, for standalone use, I'm looking at a remote-control solution to have a computer switch the TNC to remote control mode, tune the VFO's, then switch back to the TNC. It looks like this could be done in less than a second on the TMD700. > Downlnk - Uplink > _________________ > 435.120 - 145.900 Mid Pass etc etc Thanks Jim Gill N0RMO Omaha NE --- You are currently subscribed to ao16aprs as: lyris.ao16aprs@tapr.org To unsubscribe send a blank email to leave-ao16aprs-833L@lists.tapr.org From bounce-ao16aprs-833@lists.tapr.org Fri Feb 4 08:05:04 2000 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.13) with SMTP id IAA23885 for ; Fri, 4 Feb 2000 08:05:03 -0600 (CST) X-Authentication-Warning: arctic.usna.edu: bruninga owned process doing -bs Date: Fri, 4 Feb 2000 09:04:40 -0500 (EST) From: Bob Bruninga X-Sender: bruninga@arctic To: "TAPR AO-16 APRS Special Interest Group" Subject: [ao16aprs] Re: 9600 Baud In-Reply-To: Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII List-Unsubscribe: List-Software: Lyris Server version 3.0 List-Subscribe: List-Owner: X-List-Host: Tucson Amateur Packet Radio Reply-To: "TAPR AO-16 APRS Special Interest Group" X-Message-Id: Sender: bounce-ao16aprs-833@lists.tapr.org Precedence: bulk Yes, but look at the doppler rates shown by your trackihng program.

Most contemporary dual band radios have the ability to program non-standard splits, including transmit/receive in different bands. Even the Alinco DJ-G1T 2 m HT, which is only a 2 m rig, will receive on 70 cm, and allow you to program non-standard splits, including transmit/receive on different bands. Stock, it will not tune below 440 kHz, but there is a mod on http://www.mods.dk which involves pressing 3 keys to "open" the receive to include the Oscar subband. I program non-standard pairs in my Yaesu FT50 for working AO-27 and SO-35. However, since neither of my HTs are full duplex, this technique only works in half duplex rigs. There might be an error in my logic with the Kenwood rig, since I assume it's using separate VFOs. My post was mostly a result of brainstorming, where I am considering using an old Yaesu FT5100 for the pacsats. There is a mod for 9k6 packet on the aforementioned site, and the rig has a function called, "Alternating Band Memory Selection," where mic clicks can select programmed memories from either band/VFO. I think, and again I'm just brainstorming here, InstanTrack, in conjunction with Tony's (AA2TX) InstanTune, which will operate a rig through the mic click interface, would work for the pacsats. Both programs are available for download from the AMSAT site, under PC software: http://www.amsat.org/amsat/ftpsoft.html#pc. I don't own a TMD700, and haven't had occasion to play with one either, so I can't comment. If you'd like to send me your's, say for a few months, I'd play with it and get back to you! :-) I'm sure I'll be corrected if it's been done, but I don't think anyone has been successful using that particular rig to effect a two-way communication with UO-22, although Jeff, KB2WQM HAS digipeated several messages to me through UO-22, a pacsat gateway, APRS, and into the Internet. Several great minds, including Jeff, are working on it.
