FM Multiplexing:

 Huldra 8 is prepared for FM stereo reception. There is dedicated space for a 

connector for an FM stereo decoder. The stereo indicator lights up on stereo reception. 

Duplex dial:

 There are 2 frequency indicators; one for FM and another for AM. The frequency dial 

is automatically switched to the selected wave band. 

FM Tuner:

 3 tuned circuits with bandpass filters in the high frequency stage. The FM amplifier has 

4 stages with bandpass filter and discriminator. 

Favorite station markers:

 5 moving markers to indicate your favorite stations. 

Automatic FM fine tuning:

 When dialling in a station, the AFK function will automatically fine tune 

the frequency. This function can be switched off. 
Interference filter: 9 kHz filter for AM 

Selectivity selection

 for AM local or distant stations. 

Tone controls:

 Choose between pre-defined tone curves and variable bass and treble control with 

graded scales. The tone selector has 6 positions, of which 4 are pre-defined tone curves: 

Mørk

 

(Dark), 

Tale

 (Speech), 

Normal

 and 

Bass

. In these 4 positions, the dedicated bass and 

treble control dials are out of function. The two last positions are for individual variable bass and 

treble adjustment using the dedicated bass and treble controls. In position “Variabel 2”, the bass 

increases with reducing volume. This is called physiological bass compensation (Loudness.)
