Remote transmitter circuit diagram

This transmitter provides a far-field signal source for tuning Yagi and other beam antennas . Q1 is the Pience oscillator, which works in the main oscillation mode of the 7.06MHz crystal and can be used to measure the field strength of 14.12, 21.18, and 28.24MHz in the 20, 15, and 10m frequency bands. The antenna is two sections 1.5m long, connected to form a dipole. T1 is an Amidon skeleton T50-2 with 22 turns in the primary and 20 turns in the secondary with a center tap. T2 uses the same frame, with 22 primary circles and 5 secondary circles.
