I don't see any problem on the software side, nor on the receive side. On transmit, the LPF to use seems to be "C" which is currently used for 40m and 30m (10.150 MHz highest). 60m 2nd harmonic will range from 10.6 to 10.8 MHz which may be a problem for that filter - it may not suppress that 2nd harmonic well enough.
I have the equipment to test the filter frequency response, but I'm afraid of the PCB hacking required to inject an isolated, calibrated RF signal just through the LPF. Just programming the tuning to cover the range can tell me something by measuring the SWR and power, but my sbitx v2 is untrustworthy on that point. I probably need to convert it to v3.

we do not have the space on the user interface for another band button. The 60M can be used with reduced power with the 3.5 MHz band. I havent tested it so far. I will test and incorporate, we are moving this to the list of desired features
