Some time ago Museum Jan Corver has obtained a huge number of portable
transceivers that had been used in the truncking network of Schiphol
Airport (Amsterdam, The Netherlands). As we were very busy working on other
amateur projects, these handies ended up in the warehouse and we almost
forgot about them. Until radio amateur Rob Spijker decided he wanted to
write software for it. He kept his promise and as a result we are able
to offer this portable transceiver now for use in the 2m amateur band.
All that is needed to convert this portable unit is... software!
At the bottom of this page are a number of files for download and
some links that may help you any further. If you have worked out another
application for this unit, please don't hesitate to contact us, so that
we can share your experiences with other amateurs. Send any information
to firstname.lastname@example.org and we'll do the rest.
Our initial goal was simple: try to modify the software in the
transceiver in such a way that it still fits in the existing
EPROM whilst providing all functionality to use it as a 2m
amateur handy. Rob Spijker, PE1RJY, considered this to be
realistic and took off...
Although the modification consists mainly of software, there
is a little bit more to it. Once the new EPROM is in place, it will
be neccessary to re-align the transceiver and optimise it for
use in our 2m band. The initial version of the software has
deliberately been kept simple, and the result is a very
robust and reliable portable transceiver for the 2m amateur
band, operating between 144.000 and 146.000 MHz in a 25 kHz
grid. A later version of the software allows operation in a
12.5 kHz grid, albeit with the need to replace the crystal in
the reference oscillator.
The Teleport 9 portable transceiver can be bought from the Museum for
a symbolic price and will be supplied with the new EPROM already
in place and full instructions. Please refer to the section
Download below for the latest software release. Also available
is the latest version of the documentation in PDF format.
Please refer to our price list if you want to buy it.
Already after a few days, this robust handy was given the nickname
The Blue Brick. The picture on the right shows why.
The aluminium case has the size of an average brick...
The picture also shows the optional battery charger of which
only a limited number was made available. Please check the
price list for availability.
The circuit diagram of the charger is available from the Download
section. At one side of the charger you'll find a rather strange
Hirschmann mains connector, but fortunately we also have the
appropriate mains cable available. Multiple chargers may be
chained together, using only a single mains cable.
A separate car kit exists, enableing the use of the transceiver
in a car. The circuit of this car kit is available in the Download
section as well. It allows the use of the handy whilst driving
and will charge the battery at the same time. External connections
are available for microphone, speaker and antenna.
Helical antenne for the Teleport 9
Initially, all handies were supplied with one NiCd battery pack,
but unfortunately we've completely run out of stock. Suitable
battery packs may be found on the Internet sometimes, but the
quality of most packs has been much reduced due to the fact that they've
been left uncharged for quite a long period. If you find the quality
to be unsufficient, it might be neccessary to replace the NiCd cells
with new penlight models.
If you haven't been able to obtain an original battery pack, you
may want to create one yourself, based on a standard battery holder
available from most electronics stores. A suitable pack could be
constructed from surplus PCB material, for example.

A number of external controls may be connected to the expansion
connector at the rear. Pins are available for the PTT (Push to talk),
external microphone, selective tone call and loudspeaker.
If you have been able to obtain the rather rare expansion connector,
you might connect an external speaker/mic to it.
All pins of the expansion connector are fully described in the manual
(also available in the Download section).
In order to allow the PTT to be used through pin 5 of the expansion
connector, it might be neccessary to remove links D and E from the
motherboard and install link F.
Alternative software for the Teleport 9
We are currently working on a new release of the Teleport 9 software.
This software will enable the use in a 12.5 kHz grid and will also
reveal some new features.
It has been brought to our attention that a third party has made
an alternative software release available for this transceiver.
This software is not supported by us and
seems to have some serious flaws.
