Superstar 2800 alignment
Can anyone give information on the alignment of a Superstar 2800 radio? It is supposed to be identical to the Polmar Oregon and Formac 777 models. Thnks.

Re: Superstar 2800 alignment
The diagram is going to be very helpful, although in principle it seems somewhat different from the station, since the Superstar has 6 channels and a single crystal to change frequencies, while in the Polmar Oregon diagram it seems that there are 7 crystals for the 7 different channels, a true luxury. Thanks 14CS06!

Re: Superstar 2800 alignment
I didn't know that there are two different versions with 7 channels each. The one I have uses a single crystal for all 7 bands, and is the same as your second image. I attach here some photos with details.
The main problem is that it is somewhat displaced in frequencies (all of them) and I need to center them. I see that there is a block with three air capacitors (trimmers): CT2, CT172, CT173 and another one further away from the front that has 2 capacitors: CT6 (red color), CT7 (black color). I would like to know what their function is, and how to center the frequency. Thanks
