- A while back I posted a question about the possibility
- of a local FM broadcast station causing desensitization
- of a Pro-2006 scanner following the installation of a
- Diamond discone roof top antenna. Several replies
- confirmed my suspicions based on the evidence of reception
- IMPROVING when a 10dB attenuator was placed in the
- antenna feed. I have since installed the Grove Scanner
- Filter which is a passive device that notches out
- several bands including <30Mhz, FM broadcast and TV
- broadcast. For those who requested I post the
- results of using the filter, I am pleased to report
- that the "desense" problem went away instantly. I was
- however, somewhat disappointed with the filter from Grove:
-
- 1. the backside of the one-page instructions was
- so poorly photocopied, it was illegible
- 2. the connector at one end of the filter had
- become unsoldered and had to be fixed
- 3. the instructions for adjusting the adjustable
- notch filter were not clear and the diagram
- did not match the circuit board layout
-
- Grove have served me well twice in the past and I
- hope this is not a trend.
-
- cheers,
- Peter
