but you have to join to download it. Amplitude modulated, HF test oscillator. Five fixed frequencies selected by switch: 262, 455, 465, 600, 1400 KHz. Two crystal sockets on the front panel for optional frequencies. Accuracy: + -0.5%. LF modulation: 400Hz at 30%. Available outputs: continuous HF, modulated HF and LF (by switching). Continuously adjustable output level. LF output level: 10V. HF output level: 0.1V. Title: Re: Heathkit TO-1 Test oscillator Post by: Chuck SWL on September 18, 2021, 03:20:53 PM Try this:
