> Dear PACTOR friends!
> Just like every year we want to invite you to visit us at the
> Ham-Radio exhibition in Friedrichshafen, in the south of Germany. The
> show takes place from 23th until 26th of June. Our booth is located in
> hall 1 and has the number 432. As always we have a new firmware for
> all our PTC-IIxxx modems with us, more on that item below.
> Additionally we are going to introduce two new PTC modems, which are
> the PTC-IIusb and the PTC-IInet.
>
>
>
> The PTC-IIusb:
> --------------
> As the name indicates, with this product we want to accommodate the
> increasing demand for a modem with direct USB connection to the PC.
> The external V24/USB converter is with this not required any more.
> With its features and functions, the PTC-IIusb finds its place between
> the PTC-IIex and the PTC-IIpro. Like the PTC-IIex, it is a single port
> unit with just one radio connector, which is capable of all known
> modes alternatively, but not simultaneously. But just like the
> PTC-IIpro, the PTC-IIusb has a full featured transceiver control port.
> Thus, with this unit it is possible to control a transceiver from the
> USB port of a PC. The size of the housing is the same as the
> PTC-IIpro. In opposite to all the other modems we refrained from
> backing up the memory with a battery because this has sometimes
> created some trouble, especially under maritime operating conditions.
> Finally, with our new modems we have the power switch on the
> frontpanel, which was also asked for by many users.
>

> The PTC-IInet:
> --------------
> The PTC-IInet is a combination of a PACTOR modem (with transceiver
> control) and a Linux-PC, where both find their place together in a
> PTC-IIpro sized case. The PTC-IInet has a network connection (Ethernet
> 10/100) and can with this directly be connected to a router. If that
> router is connected to the Internet (e.g. via DSL- or cable-modem)
> then the PTC-IInet is also "online" this way.
>
> When the PTC-IInet receives a connect from the outside, it serves as a
> gateway into the Internet for that distant station. This function is
> called "PACTOR-IP-Bridge" (PIB) and works similar to WLAN, but with
> the advantage of a very large range of coverage and the disadvantage
> of narrow bandwidth. The PTC-IInet is by default delivered with
> PACTOR-III and can be configured with a standard webbrowser, which
> means that it has a build-in webserver. It is the same method how
> routers and WLAN accesspoints are configured, so this procedure can be
> assumed as well known.
>
> Another interesting viewpoint of having a networking PACTOR modem
> device with transceiver control capability is the fact, that with
> transceivers can be controlled via the Internet this way from any
> point of the planet. The PTC-IInet largely supports that feature with
> its web interface.
>
> The web interface also supports automated updates of the firmware and
> Linux kernel via the Internet. With a simple click on a button, the
> PTC-IInet connects to the SCS Internet server, looks for updates and
> installs them automatically, if available.
>
> If anybody wants to "play" with the web interface of a real PTC-IInet,
> he may use the link to one of them here at the SCS facilities:
> http://dl1zam.dyndns.org. I'm really curious how many simultaneous
> connections it can serve :-) A detailed article about the PIB with the
> PTC-IInet is available here:
> http://www.scs-ptc.com/download/pib_review_eng.pdf

>
> New Firmware 3.6:
> -----------------
> The version 3.6 firmware considerably increases the functionality: For
> the first time the PTC firmware supports "Automatic Position Reporting
> System" as "stand alone" service. A PTC can be used as a position
> "Tracker". The generated datagram is APRS compatible.
>
> Version 3.6 offers a further important new feature, an innovative,
> robust modulation mode for HF-Packet-Radio (HF-PR). This is also the
> ideal method to transfer position data with high reliability via
> shortwave. As a special feature for all the variants of "Robust PR", a
> completely new synchronizations algorithm with "catch" properties that
> were not possible before has been implemented. Frequency deviations of
> up to ?250 Hz are immediately recognized and compensated without any
> loss of sensitivity, and this with signals that are buried deep in the
> noise.
>
> The new modulation method (Robust Packet-Radio) is available for free
> for the PTC-IIex and PTC-IIusb. For the PTC-II and PTC-IIpro a new
> DSP-Modem-II (plug in module) will be available from SCS as of June
> 2005. The new DSP-Modem certainly offers all the past PR-modulation
> modes (300-19200 Bd). Only the PTC-IIe is unfortunately not
> upgradeable for "Robust-PR".
>
>>>> IMPORTANT for the (old) PTC-II <<<
> The firmware (firmware file profi36.pt2) will only be started by the
> PTC-II when the PTC-II is equipped with 2 MB of RAM. The PTC-II is
> upgradable to 2 MB of RAM, the price for that upgrade has been reduced
> to the half to make the decision easier.
>
>
>
> Further enhancements of the firmware 3.6:
>
> - Auto GLL/RMC when GPS receiver is connected.
>  Firmware now accepts parallel $XXRMC as well as $XXGLL (XX = GP or
> II).
>  RMC has priority. As soon as RMC is received the firmware does not
>  look for GLL any more for 15 seconds (retriggered).
>
> - On hostmode channel 249 the PTC-IIex provides all NMEA sentences of
> a
>  connected GPS receiver. Except the terminating <CR> (ASCII13) the
>  data is exactly matching with the one the GPS receiver sends. 32 sets
>  of
> NMEA
>  data are buffered internally. This NMEA channel is also included in
> the
>  extended hostmode channel 255, which means that the usual poll on
> channel
>  255 is sufficient to determine if there is new NMEA data available on
>  channel 249
>
> - Dynamic FRack with Packet-Radio connection: Automatic adaptation of
> the
>  retry timing creates a higher average throughput under weak
> conditions.
>
>
>
> The SCS website will be updated after the Ham-Radio. Then all new
> products will be available in the webstore and the new firmware will
> be ready for download.
