The RF-Amplyfier Creator forgot to instal between Source and Gate pins of both MOSFET the 2pz. of 14Vz Zenner diode. So if you send,in input from transceiver, signal too much strong like 10w(voltage > 15Vpp) you could burn the pins gate. The jack for band change not work, the jack for PTT work; I recommend you to separate PTT transceiver signal to PTT transceiver RF Amplifyer using or two different switch, or one switch (two way) or one relay two ways. I attached similar scheme with two Zenner diode and where solder it. Other problem there is not.This Amplifier is compatible with: Recent RS-918, most SDR like blackBrick and other. IT'S VERY IMPORTANT INSTALL TWO 14V Zener Diode (9.1Vz + 4.7Vz) to not burn gate af monolithic mosfets.THE MAX MOSFET POLARIZATION IS 15V
