Hello Irad, I would like to request manual up/down cat control buttons. It happened to me in several occassions that I forgot to press the ok in the warning screen. The other station does QSY up or down but there is no way to do a QSY within the software without manually tuning your radio. These QSY buttons would also be useful to check if 750Hz up or down is occupied by other varac users. So far the QSYD and QSYU buttons are only working to request the other user goes up or down. I hope you understand what I mean. 73, Bas PE4BAS
