Having put in the battery, you have to adjust the trimmer capacitors. It is best to start testing with “fuli power”, i.e. the potentiometer fully tumed clockwise.

To adjust the trimmer capacitors you should preferably use an isolated screw-driver — in order to not influence the tuning circuits too much. You can now adjust each tuning position. Notę that the position of trimmer capacitors does not correspond to the switch position. Counting from the left to the right the switch positions 1 to 6 correspond to the trimmer capacitors 4, 1,2, 3, 5, and 6.

As mentioned before, it is possible that very strong stations will distort. In that case you should lower the gain with the potentiometer.

In practice it is not difficult at all tó align the tuning capacitors. Once you have done it, your K7 is programmed for life.

The K7 in everyday life

The switched tuning of the K7 radio is a verv useful feature. While listening to this little radio you’11 find it very easy to change from station without the difficult tuning which generally take a bit of attention.
