| This is
a VHF communication radio for Kriegsmarine. This was used for voice and Morse code communications in warships, submarines and coastal fort. Frequency range: 37.55 to 45.75 MHz Modulation: A2 and A3 (toned CW and AM) IF frequency: 6 MHz Tx Power: 10 Watt Weight: 13.5 Kg Designed in 1938 by Lorenz Produced: 1940 - 1944 Weight: 13.5 Kg This radio is based on Fug17. The frequencies are divided into 18 channels.. |
| This is an early version of
Lo10UK39. It has a design that fits into a warship. This unfortunately missing volume control and two buttons for frequency control. I are now working to finding these parts.. |
| Close up of the front of the radio |
This radio can also communicate with Lo1UK35.
The cover is removed and you can see here how the radio is
designed internally.

Here is the frequency scales
for Rx and Tx.
One sees here the 18 channels printed on the discs.

| Frequency settings for the
18 channels. It's just not installed any mechanism to serve these frequency settings. Strange that these channel settings are installed and not the mechanism to work with them. |
| Close up of the tuning
capacitor to the transmitter. Fantastic mechanics. The stator is machined out of a large block of aluminum. The rotor is mounted on a super accurate porcelain shaft. Porcelain shaft is mounted on two ball bearings. |
The later
version of Lo10UK39
Later in the war, also front plates was Fug17 design.
These frequency control buttons are not used in Fug17
This is a fantastic compact VHF transceiver.
Here is receiver the middle section and the transmitter
separated.
It is fantastic to see this mechanical precision.
Here receiver taken apart. From left are the audio amplifier, RF
section and MF section.
Here are the entire radio taken apart.

RF section. To the right
oscillator. The coil is made of porcelain with copper coil.
This produces a Fantastic frequency stability.
