What are the coils U2 and U2 like? Two free standing enamelled copper coils, or are they on a former?
The spacing of the turns in each winding and the proximity of U2 and U3 to each other is also critical to proper operation. That is what I gain from that American PE FM one valve receiver.
A kit working at these frequencies really does need comprehensive instructions expressed in without technical jargon in the buyers native language.
It looks as if whoever is producing these kits has not had anyone attempt to assemble and use it.
If they had any technical knowledge they would have realised the 1A2 will not work at the intended frequencies.
