Hi, I have a Futaba Single Conversion RX.

Due to the fact that my LHS did not have any genuine Futaba crystals in stock for my receiver, I put them on order to have them delivered to me when they arrived. I have just received them and while I was inspecting them I noticed that they were dual conversion crystals. I just want to confirm that I can not use dual conversion crystals in the single crystal rx, before I go through the trouble of sending them back to have them replaced.

I understand the difference in technology for the actual receiver between single and dual conversion rx, but I am not to sure what the actual difference in the crystal is, since my (very) basic understanding of radio technology is that all the crystal provided was a reference frequency that the receiver used to decode the signal.

Thanks
