LimeSDR as a Amateur Radio Transciever

Here are a few more newbie questions.

Let’s say I’m interested in 10 meters waves (28 MHz). According to the picture in this discussion:

… on this frequency LimeSDR gives about 16 dBm output power on TX1. Can I use LNA4ALL on output to gain a signal (21 dB according to this table)?

It means that LimeSDR will be turn into 37 dBm (or 5 W) transceiver, right?

Also could you please recommend a software that can transmit and receive ham radio signals, preferably Linux compatible?
