Well i live in Romania, the radio was bought from a local dealer - but this particularly piece was brought from England (hope i'm right).
Although the scale is expressed in kHz (550-200), the received frequencies are between 550-1600khz (I have a local radio station that broadcasts in 1035khz and i can receive his transmissions loud and clear).
Despite the difference in appearance, yes - I tend to believe that the model UOP975F is identical in terms of electric scheme with P975F model.

But initial problem remains - reformulated - does someone has a diagram of P975F?
