Just hooked up an oscilloscope to my HF antenna feed line and it looks like I'm getting a large ~1 MHz signal from the antenna before being filtered in the transceiver to receive 14.074 MHz.

Als Antwort auf Bo Morgan • • •The image shows a digital oscilloscope screen displaying a waveform. The oscilloscope is a RIGOL TD model, as indicated by the text at the top of the screen. The waveform is a blue, sinusoidal pattern, oscillating around a zero voltage line, which is marked at the center of the screen. The vertical axis is labeled with voltage values, and the horizontal axis is labeled with time values. The voltage scale at the bottom of the screen shows a range of 20.00 mV per division, and the time scale shows a range of 1.000 µs per division. The frequency of the waveform is indicated as 2.000 MHz. The screen also shows a cursor at the peak of the waveform, and the voltage at this point is displayed as 0.00V. The background of the screen is dark, with a grid of dots to help measure the waveform's amplitude and period.
