The Elad FDM-DUO  will Tx down to DC (well, 10kHz really),  0dBm  from a low power port and has its own internal soundcard so Tx level is always matched perfectly when using digi-modes.  You just need to add a PA.

It is certainly not a cheap rig, but is a lovely bit of kit as a modern SDR transceiver.   And of course can be locked to a 10MHz reference input.

The low power output will work up to 165MHz, so useful for 70 and 144MHz bands.   The Rx will work there, provided you bandpass filter out aliases.  Tx does not have alias problems as it uses a higher sampling rate than the Rx
