In Japan, we cannot hear the AM modulated signal except 50MHz in these days. And some of the operator of 50MHz AM use hand made rigs. I may introduce you about my simple and useful transceiver in this page. Receiver is constructed by a normal single super heterodyne. IF-frequency of it is 10.6MHz.
Crystal filter is also home brew.
1st gate of it is 50MHz signal input. 2nd gate of it is 40MHz oscillator input. IF signal as the different of these signals. Crystal filter is 4 element ladder. It is the character of the filter.
