Theoretically is very easy to integrate a "shift multiply by..." field in the advanced settings to allow to produce 4x the shift between the dashes so it comes out in the normal level after dividing by 4. This would be very MF user friendly and is desired for a mode on MF/LF. People can use a HF TRX and run JT9 on 160m. After dividing the QRG by 4, we arrive on 630m! (1900 kHz / 4 = 475 kHz)... This divide by 4 concept will certainly used by many MF amateurs for a longer time. 73, Stefan/DK7FC PS: I remember that Dl4YHF has added this feature to the digimode terminal to produce DFCW on VLF, which helped a lot.
