|Welcome on my Homepage|
|On this pages you will find informations about radio equipment that I have developed. Some are available as kit or ready-made unit. You can download data sheets or construction manuals of most of them.|
Transverter for the 4 Meter Band
The transverter is available from stock as kit (185.-€) or as ready-made unit (259.-€).
Here a flyer and the complete manual (currently only in German, English version follows).
If you are interested to obtain one, please send me a mail.
70cm PA with ultra short RX/TX delay for FM and digital modes
P40XDigital operation modes become more and more popular in amateur radio. Here transmission protocols are in use which require extremely short latency times for receive and transmit switching. With TDMA schemes like MOTOBRO or DMR they are below 1 Millisecond. Standard power amplifiers with relays are unusable then.
The P40X amplifier uses pin-diode switches and doesn't have that limitations. It is perfectly suited for modulation schemes with constant envelope like FM, GMSK and C4FM.
Frequency range: 420...450MHz
Output power: up to 40 W (depending on supply voltage and drive power)
Supply voltage: 11 ... 13,8 V
Input power: 0.4 ... 5 W
RX/TX delay <100 micro seconds
The device is available in short at AndroidDMR.
Now with USB interface and improved RF front-end
Receiver for Weather Satellites with Antenna diversity
There is a new R2F-Config version available. It is working also with Windows 10 and all problems with RS232-USB converters seem to be solved. You can download it here.
