    Flashback

   
   

The development of equipment for technical experimental radiocommunication service represents a not unimportant part in the company's (pre) history.

   
 

From the beginning Hilberling is the specialist for development and production of components of high-frequency and radio telecommunications.

   
   


VHF 2 m Band Panorama Receiver PC200 · Display on TV-Screen / Monitor





   
   

In the course of technological change new circuit and device concepts were repeatedly created which were introduced and presented to the interested reader for private reproduction by OM Hans Hilberling in the form of first publications in professional journals.

   
   


Mobile Transceiver Kit MT80/20 · 12 V · 100 Watt · CQ DL 4/5-77





   
 

Examples for the use of analog technology in the spectral analysis.
Panorama Receiver / Spectrum Analyzer

   
   


Spectrum Analyzer  SA677 · 100 kHz ... 1.5 GHz
Center Frequency Secondary Receiver AM / FM






   
   

Detailed descriptions and the option to purchase a complete kit made it possible to reach even the less experienced radio amateur in the possession of a high-quality and inexpensive device.

   
   


20 m Band Receiver Kit RX14 · 5 ... 15 V · CQ DL 12-81





   
   

1980 first synthesizers with Pal-TV delay line or channel spacing kept entry into the transceiver technology.
In this example the unpublished 5-band Hilberling Transceiver MT80-10:

   
   


5 Band Mobile Transceiver MT80-10 · 12 V · 100 Watt





   
   

The PLL technology with tunable phase shifter and Pal-TV delay line (FM Braun devices) is well suited for DIY projects.
As here the HF receiver RX16 from the ham radio forge Hilberling in 1985.

   
   


SW All-Mode Receiver RX16 · 9 kHz ... 16 MHz · 12 V





   
      Laser Modulator    
           
 

First development sample from the early days of Hilberling GmbH.

   
   


100 W HF Generator QSD W12 · Switch-Off-Time 150 nsec





   
      Beginnings of WLAN Technology    
           
 

From the initial idea to the finished industrial product we advice, develop and produce as a partner of large companies.

   
   


128 k UHF Data Radio Modem




   
      MIL HF Transceiver    
           
 

Project: Military HF Emergency Radio Systems

   
   


Computer Controlled Short Wave Transceiver  HT2050 · 1.5 ... 30 MHz
AM / SSB ·100 Watt PA  · 12 / 28 V
Full Emergency Radio Operation with Control Unit in the Handset


   
         
      Direction Finder    
           
   

Fox hunting receiver for sporting radio direction finding competitions.
As an example the fox hunting receiver Heide for the 80 m / 2 m band.


   
   


Fox Hunting Receiver Heide · 9V

   
         
      TV Picture Transmission (SSTV)    
           
   

Slow-Scan-TV providing 8-second frames shows the beginnings of image transmission in telephone lines.

Shown below the combination of rotating "drum scanner" and afterglow radar tube allowed without today's memory chips continuous image transmission in the radio voice channel.
