beacon in dBm?<br>What is the level and frequency of the interference?<br></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:times new roman, new york, times, serif;background-color:transparent;font-style:normal;">Is the interference constant and always
present?</div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:times new roman, new york, times, serif;background-color:transparent;font-style:normal;">What happens if you gradually switch in more frontend attenuation in Hermes, say -10dB and -20dB?</div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:times new roman, new york, times, serif;background-color:transparent;font-style:normal;">Did you try connecting Hermes directly to your antenna without the Anan?<br></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:times new roman, new york, times, serif;background-color:transparent;font-style:normal;">Thanks,</div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:times new roman, new york, times, serif;background-color:transparent;font-style:normal;">Andrew</div>G4XZL<br><br><br><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new york,times,serif; background-color: transparent;

I end up with over 20 images of the beacon across the bottom<br>section of 50MHz. (50.0 - 30.350 is my window of interest)<br><br>Now I am a SDR novice so it may be something I am doing that is wrong but at<br>this point I have not made any alterations to the standard HERMES config but<br>have been
using the ANT3 input on the ANAN-10 PA board.<br><br>Can anyone on the reflector offer any advice on how to improve the strong<br>signal performance of HERMES on 50MHz?<br><br>Regards,<br><br>Peter Sumner, vk5pj<br></div></div></body></html>
