Lorenz Lo10UK39 Radio

The Lo10UK39 is the Kriegsmarine version of the FUG16/17. It was made for short Range communication between ships. It could be seen as the successor to the Lo1UK35.

The Lo10UK39 is a very modular design. Everything can be taken apart easily by just removing a few screws. The Receiver can also be operated disconnected from the rest as a standalone unit. The receiver is on the left side. The middle is the Bediengerät mostly for the Transmitter and to remotely turn the power-supply on and off. The Lo10 has multiple preset channels same as the lo1 wich also overlap.

This Modell was produced in 1942 and has a Kriegsmarine stamp above the type plate. The receiver and Transmitter are made the same year but have different serial numbers. I believe they still belong together the factory probably didnt care if the serial numbers matched. At least I have never seen a Lo10 with matching Numbers.

On the backside the Lo10UK39 has the same connectors as the FUg16/17 and also the same fastening hooks for the Rahmen.

On the Left side Vents for the big RL12P35 Tubes can be seen.

The Lo10 has a loot of different stamps really a huge amount. also visible are the different serial numbers.

The S behind the Lo10UK39 stands for Transmitter in German Sender

Same for the E=Empfänger. Again a loot of stamps…

Serial numbers Transmitter 187 Receiver 165 Front plate 170. Also visible is some very nice cable management.

On top both RL12P35 Tubes are visible and some of the RV12P2000. One shielding plate is missing.

The Transmitter from above. very nice quality and perfect shielding.

Receiver from above Never opened before the screws are still sealed. But it works!!

Both RL12P35 Tubes nicely visible from the side. Everything is build very tight to use as little space as possible.

The bottom side.

The morse key connector can be seen from the back. Also visible is the Tastrelais. When the morse key is pressed this relay opens disconnecting Voltage from the grid of the Transmitter tube. Look at alle the cables tied together.

On the bottom the STV tube is visible for Voltage Stabilization. And Even more RV12P2000 tubes.
