The first set of data was collected using the normal filter at DSS 15, and the second (XLCP) was collected using a new spare filter. The data aren't really LCP, the same signal is sent to XR and XL channels. 328/20:00:00 to 328/20:24:00 XR 328/20:26:00 to 328/20:38:00 XL Please let me know how the filter on the XL channel looks -- especially if it looks better than the other one. The antenna was at low elevation angles. Now that I think about it, it might be better to collect some noise without carrier for filter comparisons. I can do that after Thanksgiving. Thanks. Have a great Thanksgiving! -Trish -------------------------------------------------------------------------- From rsimpson Mon Nov 29 17:23 PST 1999 Received: (from rsimpson@localhost) by magellan.stanford.edu (8.9.3/8.9.3) id RAA20487; Mon, 29 Nov 1999 17:23:11 -0800 (PST) Date: Mon, 29 Nov 1999 17:23:11 -0800 (PST) From: Dick Simpson 723-3525 Message-Id: <199911300123.RAA20487@magellan.stanford.edu> To: trish@rodan.jpl.nasa.gov Subject: Re: Filter comparison Cc: rsimpson Content-Type: text Content-Length: 907 >Data were collected at DSS 15 for a comparison between filters.

The XL data look much worse. I'll FAX you the plots. >Now that I think about it, it might be better to collect some noise >without carrier for filter comparisons. I can do that after Thanksgiving. It's possible the peaks in the XL spectrum were somehow connected to the presence of the carrier. But, if everything else was the same, that means the filter is still worse because it doesn't respond well with a strong signal. -------------------------------------------------------------------------- From trish@rodan.jpl.nasa.gov Tue Nov 30 11:55 PST 1999 Received: from godzilla.jpl.nasa.gov (godzilla.jpl.nasa.gov [137.78.177.120]) by magellan.stanford.edu (8.9.3/8.9.3) with ESMTP id LAA07747 for ; Tue, 30 Nov 1999 11:55:26 -0800 (PST) Received: from 137.78.177.117 (trish-mac.jpl.nasa.gov [137.78.177.117]) by godzilla.jpl.nasa.gov (8.9.3/8.9.3) with SMTP id LAA00784 for ; Tue, 30 Nov 1999 11:56:10 -0800 (PST) Message-Id: <199911301956.LAA00784@godzilla.jpl.nasa.gov> Date: 30 Nov 99 11:55:31 -0800 From: Trish Priest Subject: RE: Filters To: "Dick Simpson 723-3525" X-Mailer: QuickMail Pro 1.5.4 (Mac) X-Priority: 3 Reply-To: Trish Priest MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset="US-Ascii" Content-Length: 1138 Status: RO Reply to: RE: Filters Dick Simpson 723-3525 wrote: > >>You will receive the usual notification for the DSS 15 pass on DOY 334. >>The first recording is XR and the second is XL (same signal different >>path).

I tried to get some data from DSS 25 and discovered that you can't do the same thing with that station. I didn't think that I sent you any notifications for those. Any XL from DSS 25 is garbage. -Trish
