RFI Suggestions
If your Observation is hampered by RFI, you could do the following:
Charactize the RFI - determine its frequency, bandwidth, nature
of emission (CW, burst, radar, etc).
Do you see it on the Hill-top monitoring plots ? See either
the print-outs in the control room or the On-line display
using ARTS rfi, or ANALYZ. You may take a look at the
anual statistics to see if this was ever seen by the
Monitoring system.
Look in our gripe data base to see if this was ever reported by
other observers.
Run a program called "search" to find if your RFI could be
harmonically related to any FCC registered spectrum user in PR.
Click the appropriate button in ARTS rfi, or simply run:
~rfiusr/search on the observatory's SUN network system.
If this search finds a possible installations that could be
causing the RFI, you may use the FARS data base on the PC
in Rey Velez'z office to get the name, telepones number
etc. Please pass any such info to the RFI group via the
Complaint/report form.
If you suspect that it is generated locally, you may use the
hand-held radio AR8000 to identify the equipment. A short
one-page manual for how to use the AR8000 is avaialble from
the telescope operator.
