 Adding more modules to the arrangement could create a complete set where the receiver would be independent on a computer. Its realisation has several variants:
-  * The receiver with a tunable oscillator and module with LDC that would show the tuned frequency. The buttons below the LCD would allow the retuning of the receiving frequency.

-  * A second variant would be the same as the first one, with an exception of digitising the analog output, that would be transmitted through some kind of a common interface to a computer (USB, ThunderBolt, Ethernet, ...). The same interface could be used for LO tuning as well.
