Re: More Chinese AM radio kits
Hi
I bought two of the HX108-2 kits at different times and have just had a look through the contents.
There are subtle differences on the circuit diagrams, not in the actual circuit, but rather in the additional information.
In kit 1, the kit is described as HX108-2 on both sides of the sheet. The IF and oscillator transformers have the normal bold colours (see pic 1). The driver transformer is coloured green and the output transformer is coloured yellow.
In kit 2, the kit is described as 108-2 on the circuit diagram side of the sheet and XH108-2 on the board layout side of the sheet. (note the transposed X and H). The IF and oscillator transformer colours are more pallid (see pic 2). The oscillator transformer could be mistaken for being brown in colour.
Again, the driver transformer is green and the output transformer is yellow. (see pic 3)
My aerial coil has suffered some impact damage and may be unusable in this kit.
Maybe kit 2 is a copy of kit 1 by a different supplier.
These kits seem very good value considering what you get for your money including the carriage. When I get time, I'll have a go at building them.

Symon
