Enthusiasm for Ham radio is one of the foundations that led to the formation of Hilberling GmbH.
The know-how gained through years of experience in the development and series production of industrial and maritime high-frequency products flows directly into very special products for Ham radio.
Cutting-edge technology developed and manufactured in Germany!

2 Independent Receivers
7 x 1 GHz DDS oscillators are used for two equivalent receivers and a transmitter. This offers the highest spectral purity for receiving and transmitting with the PT‑8000A.
A low-noise SAW-VCXO at 640 MHz is disciplined by a 10 MHz quartz oven. The use of 1 GHz DDS oscillators enables the lowest noise figures, which can otherwise only be achieved with non-variable crystal oscillators.
A signal-to-noise ratio of -160 dBc / Hz at a 10 kHz distance at the RX frequency of 14.2 MHz is achieved. The frequency stability through the quartz oven is 5 x 10-9.
In the PT‑8000A, 7 diplexers / harmonic filters are used in the TX output for the first time in Ham radio technology. They prevent the harmonics from being reflected on filters and antennas.
