Default WTB 2m / 70cm all modes transceiver

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.

Default WTB 2m / 70cm all modes transceiver

Hi!

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.

Efficiency is irrelevant.. this is for ARES use when all the
'efficient' systems are down.

Yep. Looks like the IC-706 family will be much easier to put in my
Jeep than an FT-897/897D would.

Lots of 9600 baud out here in the Silicon Forest, up on the Left Coast.

Being rather new at Packet, I do not understand the latter two issues.

an IC 706 would do the job.

Why would I be swapping TNCs out? Once it works, it will stay
connected, and I think I'd add a mike/TNC switch.

Because, perhaps, you too are a Penguinista? Debian distros, e.g.,
Ubuntu or Kubunto, rock, and you can run Dam Small Linux, Puppy, and
other Debian-based compact distros off a 128MB USB memory drive, which
are absurdly cheap 'round these here parts.

Merci, many thanks, 73s & best regards.

Icom 910h is worthy of consideration dula band fairly high power
(option for 1.2 gig) neer heard of vhf.uhf packet on SSB but souunds
interesting

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.

Hello,

I don't think that the TS-790, nor the IC-821 or 910H were ever meant for
mobile use...
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.

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.)

Default WTB 2m / 70cm all modes transceiver

Hello,

I had the chance to step in packet radio with Baycom 1.6 under Win95 with a
Baycom modem. 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.

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.
