I tuned my first 460 MHz band receiver using the 9th harmonic of the Marker Generator of a Heathkit TS4A Sweep Alignment Generator.
To stabilize the generator, I plugged it into a ferroresonant line regulation transformer and placed the generator under a blanket for two days first. I used the marker generator output control for the fine tuning as it loaded/unloaded the oscillator. I ran the output through an external switchable attenuator for level control. Took a long time to tune a receiver ... but got the job done. The receiver was a tubed type - from a Motorola T44A6 radio set. You got to start somewhere.
