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.

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.

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.
