Hi,
Verify the total DC Current. I remember about 85-90 mA from my unit when set at 100 mW output when it was in FSK CW mode (now CW).
Is your RF cable OK and correct impedance (75 ohms can throw a curved ball if you are not careful)
Check DC volts on stages etc/ Mine is run on 5V.
On another topic
When I modified my 30m TX to CW as on the Hans Summers site. the CW back wave was only 13 dB down and added a 56 pF to ground from FET gate which improved it down to 33 dB or so. (Other bands might require experimenting.Drive RF was driving the FET into Class C.
