There is not something else. There are digital modes that are transmitted in FM (dmr, c4fm, dstar, aprs, winlink stuff) and others in SSB (CW, wj, fsk, ft8). In my humble opinion it would be very difficult to implement all these at a reasonable price. I would be interested in a V-U version of the Bitx, that is SSB-CW. A practical solution is to simply add transverters. Some are very cheap on ebay. There are few things to be addressed. First remove spurs on SSB at 28mhz if the transverter does not have a bandpass input filter (TenTec transverter have it) . That can be done with the solution suggested by Farhan. In my opinion the transverters should rely not only to PTT but to the RF sense too in order to be sure you don't fry the transverters. 2m TenTec transverters work FB and have just the RF sense TXRX changeover.

Hello,
I'd like to experiment with digital modes on VHF/UHF and don't want any potential limitation from commercial transceivers that may be available to me.
I have many questions on the topic, but to begin, if I wanted a purpose built rig for digital modes in these bands should I be looking at SSB, FM, or something else?
I also welcome suggestions of other groups or forums where I may be able to find information about this.
Thanks
