Is it true that VQLog requires an specific file for each model of rig?
Yes, each model has some slight diferences and VQLog requires the so-called CDF (Cat Definition File) for that specific rig in order to be able to comunicate with it properly. Some of these files are located under the \CAT subfolder of VQLog in your hard disk. Additional files and more information on CDF are available here. Q) I don’t quite understand the meaning of some of the CAT configuration options. A) I will try to explain them here in mode detail. • Rig set number. You can define up to 10 different rig sets. A rig set usually corresponds to one rig and in this case you will have one rig set for each different rig in your station. But there are other possibilities, for instance: > You use separate rigs for TX and RX. In this case both will be defined in the same rig set. > You use the same rig for differente purposes. For instance, sometimes for HF bands, sometimes with a transverter for 144/28 MHz and sometimes with a transverter for 432/28 MHz. In this case you will have to def
