Do you have a specific question about the receiver? I am familiar with
the equipment. I used the BC 624 and 625 almost 45 years ago as my two
meter AM station.

Hello ,thanks for your answer.I have no precise question,I have bought one on ebay ,it is electronically complete ,and without problem (maybe the chemical condensers to change),and mecanically the mecanism of tuning has been removed ,but not the variable condensers and coils.
I plan to do use it to do radio-astronomy ,yes it may seem a fool project ,but one part of my hobby besides radio-amateur is radio-astronomy ,and I wanted to use a receiver like they were at
the beginning of radio-astronomy on vhf just to know what was received from the sun at that time .This is why I'd like to have the schematic with values of resistors ,condensers etc,and the
connectors ,so I can use it and repair it .
Thanks very much,best 73 alain f1gqb
