In view of this I have made a small change to the way I attenuate the input to the sound card to see if it helps with daytime detection. I have removed the RF attenuator at the antenna input & placed an adjustable resistive attenuator in the audio feed to the sound card input (BTW, the sound card is a simple USB dongle type & has no input gain control). I have adjusted the level to be similar to that with the antenna attenuator & monitor the daytime signals when they are present. This morning I had to re-boot the PC & restart the software so I am not sure how that will effect continuity with about 15 minutes monitoring missing due to Windows & Internet security updates. 73, Gary - G4WGT - IO83QP. ------=_NextPart_000_0076_01C9A883.81D48320 Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable

Hi Andy, LF,<= /font>

I have noticed that although I=20= can see the beacon using SpecLab the G3PLX software seems unable to detect the signal for SNR d= ata during the daytime.

In view of this I have made a s= mall change to the way I attenuate the input to the sound card to see if it helps with daytime detection.

I have removed the RF attenuato= r at the antenna input & placed an adjustable resistive attenuator in the audio f= eed to the sound card input (BTW, the sound card is a simple USB dongle type &am= p; has no input gain control). I have adjusted the level to be similar to that with the antenna attenuator & monitor the daytime signals when they are present.

This morning I had to re-boot t= he PC & restart the software so I am not sure how that will effect continuity with about 15 minutes monitoring missing due to Windows & Internet security u= pdates.

73,
