I would assume if you have a single conversion receiver and a single conversion Tx crystal it'll work. Why not just stick with the dual conversion, it's better than single. What is the difference between "Dual Conversion" and "Single Conversion"? A single conversion receivers have only one "mixer" stage. The receiver takes the incoming signal and mixes it with the local oscillator signal. The different frequency is then amplified as the Intermediate Frequency (IF) and detected for use. The draw back with single conversion is that there is a chance of "image" reception. This is where, depending on the receiver tuning, the receiver will pick up an image of another frequency at either the high or low end of the band. A dual conversion receiver has two mixer stages and two local oscilators. This eliminates the chances of image reception. Dual conversion also allows for better interference rejection. |
