Summary: Sielco designs and produces FM radio transmitters
for professional broadcasting. The in-house laboratory develops
standard and customised solutions to meet all needs. Whether
digital or analogue, each product is studied to ensure reliability,
resistance over time and a high standard of safety. Sielco
transmitters are distributed throughout the world and serve
many radios in Europe, South America, Africa, Oceania and China.

can be exploited by brute force, which may allow a remote attacker
to obtain a valid session, bypass authentication and manipulate
the transmitter.
