The following pictures show results of the basic measurements. Gain of the amplifier reached abt. 35dB in the HF range, 33dB in 6m band. VSWR is excellent at the input, better than 1.5 at the output (thanks to attenuation used). I want to repeat again that impedance matching over the full measurement chain is one of the most important parameters to achieve the correct results during intermodulation measurements. Reverse isolation is not so high as in the first kit, but I thing it will be good enough for my purposes.
