Hi Alan,I have measured the response of the S-meter of my R-75 at 60 kHz, using a W&G level generator and a Hatfield attenuator I had bought on eBay some time ago. At 60 kHz, you need a signal of -67 dBm to have an indication of S9 on the receiver. To bring it down to S3, I had to insert using the Hatfield attenuator 17 dB of attenuation. So much for the linearity of S-meters... So, for what this test is worth, apparently at my location Anthorn seems to be about 17 dB weaker than Rugby. The test is not much scientific, as I didn't take note in the past of the time of the day when I took the S9 reading, nor of its repeatability, but as a ballpark indication maybe it can say something. 73 Alberto I2PHD |
