|After the first reviews , I've tried everything...|
even changing out components. I notice that audio is not as sensitive anymore,, tried changing out audio amp..
I also tried hooking up a small wire to C1 and I do get some CW signal.. but still not loud enough with standard earphones... have to use computer amplifier..
I rather stick to MFJ cub or other.
Don't ever plan on building this kit again..

after several weeks the Receive audio is not working as it should... have to hook up audio amp to jack to hear .....too bad this particular kit is nice looking.
I now declare that I will stick to MFJ-Cub

This is the second kit after finding out from the first one that burned out... what I found out was placing a spacer under the heat sink in the second kit solved the problem... make sure you solder the Transistor to the top circuit board first then the bottom then mount the screw through to the heatsink.
I also place a spacer under the crystals I've ordered, so it won't short out. . this kit comes with 7.023. so you might want to order some apart from this kit.
Other than that , take your time and pay attention to polarity on semiconductors and components.
