SSB packet on 2m and 70cm? Maybe at 300Bd? Must be very easy and efficient... As far as I remember, no mulimode dual-band mobile rig was ever produced. Actually you only find IC-706 and FT-897 type mobiles with multimode abilities on 2 and 70. And exit the monoband multimodes such as kwd's TM255/455 (no more produced)... For mobile action I'm using an old Yaesu FT-7100, which I also use for 1k2/9k6 packet with a TNC2-Multi (IfD, Germany) or a homebrewed soundcard interface and modern Software (Flex32, Paxon 2.00.1114, WPP 3.18, Soundmodem, under WinXP). I think that in the USA, where 9k6 packet is a vague idea and TXDelays are sooooo loooong and fast switching is of no need, an IC 706 would do the job. But I would recommend to take a rig with a miniDIN (sort of PS2) plug for packet/digimode action, so not really the Icom 706 brand. The miniDIN tends to be a standard plug-and-play feature for most modern TNCs and digi-mode controllers. And I'm quite sure you wiil need som links: http://www.uspacket.org/ http://wpp.dc6hb.de/ http://www.afthd.tu-darmstadt.de/~flexnet/ http://www.paxon.de/ I intensionnaly do not give the paths to AGWPE or Winpack... I let you guess why. If you are interestd in APRS, you can install WPP or use UI-View with AGWPE, but for Heaven's sake, do not use any AGWPE version for packet radio! The sysops and your packet mates will praise you. 73 de F8BOE Olivier ...-.- K7AAY wrote: > Looking for a 2m / 70cm transceiver, all modes preferred to permit SSB > packet, which I've heard praised in this area (Oregon). > > You on-topic suggestions as to a good voice/packet mobile rig would be > appreciated.

Olivier & John- The IC-706 Mark II or FT-897 may be easier to find. But what about the TS-790? I believe it came with dual band capability, and could have another higher band added. (I have an original IC-706, which does not have the 450 MHz band.) 73, Fred, K4DII Article: 51282 of rec.radio.amateur.digital.misc Date: Sun, 04 Jun 2006 09:00:47 -0400 From: "J. D. B."

Other interesting rigs are the FT-100D and the FT-857. And no, I do not recommend AGWPE and Winpack because I can use Unix-based applications, but just because I tested them... And they both failed. Winpack: really shiny with a lot of functionnality, but too complicated to configure, and only limited to the archaic FBB systems and unreliable 7+ file format. No Bin, no BinSplit, no Didadit modes. Too old. AGWPE: the wannabe effective driver; wannado alot, ending like the swiss knives with doing nothing really the right way... Only good for APRS and overloading the packet net traffic with useless ack frames, a kind of100% link quality with 0% file transfer rates. Sometimes I really wonder how people use packet radio... In passive-mode only... So I will go on with Paxon, WPP and Flex32. 73 de F8BOE Olivier ...-.- Fred McKenzie wrote: > In article <447fdf4a$0$11007$626a54ce@news.free.fr>, f8boe-8@bluemail.ch > wrote: > >> As far as I remember, no mulimode dual-band mobile rig was ever produced. >> Actually you only find IC-706 and FT-897 type mobiles with multimode >> abilities on 2 and 70. > > Olivier & John- > > The IC-706 Mark II or FT-897 may be easier to find.

So I had to learn fast to fix the problems and to set the parameters correctly... TXD (x10 ms): delay between PTT action and packet frame launching. Depending on your TRX's PLL quality and the TNC/modem abilities. My FT51r and FT7100 handle TXD of 18 (180ms), the TM-255/455 go down to 12, the T7F (9k6/19k2 packet TRX) breaks the 50ms mark, but that with a TNC2; using a Baycom modem induces audio lag, so I had to set the TXD between 20 and 22 with the FT51r. In Europe, when your TXD is too long you get rejected... That's why you can only expect to work 1k2 packet with an IC-706 (a 300ms minimum is worse than a CB transceiver, so no Pactor too) DWAIT/DW (x10 ms): mean time delay between end of reception of a packet frame and PTT action. If a frame is recieved in this time, there's no keing up. To give a connection chance to every other station, DW is a random parameter. For 1k2, a DW of 12 is pretty fair (10 or 12 for 9k6) but less than 10 is the crocodile way and you get problems with your mates and your digi sysop. The packet frame is the audio signal coming after the end of TXD. So if your TXD is too long and your TRX can handle it shorter, you can connect and get rejected, or you cannot connect because your frame does not come out in the DW interval. If your TRX can not handle the right TXD, your packet frame is cut (and ignored). 9k6 packet is done in FM mode but it is not an F3E signal at all, as the G3RUH modulation is injected in the TRX after the audio mixer... So long for the miniDIN-6 (PS2) plug, and there's no need of a mike/TNC switch, when the 6-pin miniDIN is present. By the way, there are two different pins on this plug for 1k2 and 9k6, so be careful, the signal peeks are not the same! Other important things: Mouse cables are of no use, because even though they have 5 wires the 6th wire lacks on the wrong pin, so if you only need one connector, you must take a PS2/PS2 cable which you can cut in two pieces but no mouse or keyboard cable. There are two miniDIN plugs on some TRXs, one 6-pin (PS2 type) and one 8-pin; for the TNC you must use the 6-pin miniDIN. Well, it was a little bit long, but these infos and packet application test reports are on most packet BBS, so if you find an i-net packet BBS you should find what you need... Could also be in the europestuff on the american boxes. 73 de F8BOE Olivier ...-.- Article: 51286 of rec.radio.amateur.digital.misc From: fmmck@aol.com (Fred McKenzie) Subject: Re: WTB 2m / 70cm all modes transceiver Date: Mon, 05 Jun 2006 13:54:51 -0400 Message-ID: References: <1149198936.151961.197850@u72g2000cwu.googlegroups.com> <4483AB02.4020507@fuse.net> In article <4483AB02.4020507@fuse.net>, jawod wrote: > Please help a newbie: what is SSB packet? > I am guessing data in one sideband with 2.5 KHz bandwidth or so? > I still confuse PSK and packet. Jawod- For practical purposes, SSB and FSK Packet are the same, just different ways of generating the signal. If you have an RF carrier and shift the frequency, you are switching between Mark and Space frequencies. A typical Packet TNC also puts out audio tones that can be used to drive the microphone circuit of an SSB transmitter. The resulting signal is equal in frequency to the carrier plus (or minus) the Mark and Space audio tones. If you tune your SSB receiver to decode an incoming Packet signal, your transmitted Mark and Space freqencies should line-up with the received frequencies. However Mark and Space may be reversed. If it won't decode, switching to the opposite sideband and retuning should clear it up. 73, Fred, K4DII
