To me the most basic and straight forward way is to specify the actual radio frequency you will be radiating (on idle-tone if any is used in that mode). So all that is needed is this figure followed by (RF), and for some modes whether USB or LSB if side-band sensitive. e.g. 7.0350 MHz (RF) USB. Everyone with a Ham Licence must be capable of adding or subtracting two figures, and this method is just as straight forward for anyone with home-made or other rigs that do not have the conventional 'Black-Box' dial system. But I do sometimes give the "Black-Box Dial Frequency" plus the Waterfall audio frequency, but then try to make sure it is unambiguous by stating what is meant. e.g. USB DIAL 7.0340 + 1000 Hz, which is not much trouble to type, instead of just putting the figures. 73 Bernard G3SMW
