The Sadir was build for the Luftwaffe from 1940 to about 1942. It was replaced late in the war by the E53 "Ulm".

The SADIR R87 you have was made for the Luftwaffe, they all have the French type plate and German legends for the controls. The original French version has French legends, a squarer casing, different antenna socket and is a different colour: http://signalspaning.se/tp79001/sadir_1.jpg

It is the "Tornado" RDF version of the R87 (FuPeil A80 or FuPeil A81 depending on frequency range). The Germans had a shortage of VHF receivers (the E53 "Ulm" was delayed), so the French "Sadir" remained in use for VHF interception and RDF roles.

Hello funksammler

Thank you for your response with the technical information

In the french versions the antenna is two dipoles

The survey of doubt being carried out by imbalance of one of the two dipoles (resistor by relay)

In the photo left side of the receiver there is additional box that was added compared to the original version

Probably a more sophisticated antenna system can be a Adcock with a raised of doubt

This explains the role of the switch

An other improvement in this receiver the local oscillator is in push pull for the vhf frequency

Many thank

Regards
