Samir, Using the K3 as IF for connecting to XV-144 or other transverters should work just fine. I am using my K3 on 28 MHz to operate on 1296-MHz with a 1296/28 transverter. I ordered the 25w transverter set to drive with 1.0mw. It runs 5w with 0.25mw and full saturated output of 20w+ with 1.2mw. This is thru the KVX3A.
If you are concerned whether the K3 receiver will be adequate, there should be no concern since most transverters have conversion gain driving the IF with amplified signals. My Downeast Microwave transverter has 17-dB conversion gain; this means the noise figure of the transverter will dominate, improving the receive sensitivity by 8-dB to -148 dBm. In my case, a lower noise figure preamp is located at the antenna to further lower the system noise and improve minimum detectable signal (MDS) to -158 dBm (400-Hz bw).

I'm thinking to use K3 like IF to my XV-144. Now I'm using K2. K3 wasn't on market when this list created, http://lea.hamradio.si/~s53ww/xvrt/xvrt.htm, Table 4: IP3 values of different HF RIG's on 14 MHz and 28 MHz...
