Test Set-up and Procedure:
To test your transmitter, set up as shown in the following diagram. Make sure
the PC board is on a clean non-metallic surface and that the test area is free of
lead-clippings, hardware, and other conductive debris that could get under the
board and cause a short circuit. Before connecting the power supply, make sure
the transmitter power switch (SW1) is turned OFF (out position). The crystal
selector switch (SW2) should be set for Y1 (out position). No direct connection
should be made to your receiver during the initial test. However, your station
receiver should be turned on, placed in the CW mode, and tuned in to the
transmitter's approximate frequency . If any of the steps outlined below fail,
refer to the "In Case of Difficulty" section of the manual.
