AEG Teleport 9
By PE1BXL, PE1MIX, PE1OLQ, PE1RJY en PE1RRT

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 pe1bxl@amsat.org and we'll do the rest.
 

The concept
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.
 
The Blue Brick
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
As the transceivers were initially used at a higher frequency, the original antenna will be too short. Nico, PE1KQP, has described a method to extend the antenna so that it still can be used. It is also possible to replace the antenna connector with a standard BNC socket, so that a standard helical antenna can be used.

Batterijen
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.

External microphone
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.

Download
Below are some documents available for download. Most documents can be viewed with a PDF Reader.

Software manual (Dutch only) (PDF, 330k) (331KB PDF file)
A brief but clear manual in PDF format, explaining all features of the transceiver. Information about the use in a 12.5 kHz grid is included.

Car-kit circuit diagram (188KB PDF file)
A brief description and the circuit diagram of the original Teleport 9 car-kit.

1750 Hz tone expansion (96KB PDF file)
It is our intention to include a 1750 Hz tone in software in a later release of the EPROM. However, this might prove to be rather difficult to implement. If you can't wait, you might want to check out this small circuit.

Latest software release for the Teleport 9 (13k ZIP file) (13KB ZIP file)
This is the most recent version of the Teleport 9 software as released by Rob Spijker, PE1RJY. The software allows the use in a 12.5 kHz grid and also allows the small hidden lights to be activated. The file is a ZIP archive and contains the software in a variety of formats:
INT (Intel format)
HEX (Hex format)
3SF (Motorola S3 format)
BIN (Binary format)
