TROUBLESHOOTING GUIDE:

To put it as kindly as possible, the operations of Ramsey QRP transmitters
have been field-checked to such an extent that we can assure you that the only
cause of malfunction will be defective or incorrectly installed components.
If the transmitter does not work, the first step is to recheck ALL assembly steps
and the quality of all solder connections. In addition, check those too obvious
things we like to take for granted: cables and connectors, polarity of the DC
supply.
If the oscillator stage just does not work at all after thorough checking, it is
helpful to check your crystal(s) in a test oscillator or other transmitter.
Common trouble spots include:
Incorrect orientation of transistors
Incorrect installation of diodes
Incorrect selection of inductors
Incorrect selection of frequency-dependent capacitors
