The frontend works by multiplying the input current first by 1/wC them by gm then by wL. The result is gm*L/C. I have BF982 for testing. C=1.36pF=4pF=5.36pF, gm=25mS, L=2.63uH, transimpedance is 12.3kOhm. The frontend runs just fine, although when the signal is too strong, we get 2Vpp on the gate and the transistor distorts. That happens also in the old RX. The oscilloscope display is noisy, which is caused by the noise from the 12V linear supply. This noise doesn't disappear when the scope is switched to 5MHz, it's a LF noise. I will put some electrolytic and resistor to filter.
