"Bruce" wrote in message ... ... Now, if the receiver IS well shielded enough, if you can insert a switchable attenuator in the coax, you can reduce the signal strength significantly...and, FM receivers get very non-linear below about 20dB quieting, they quiet faster than the actual input. In otherwords, you could get 3-4 dB quieting change for 1dB of singal change. What this will do is make you antenna pattern SEEM narrower.... -Bruce Two things here. The "offset attenuator" gets you the equivalent to a shielded receiver without the shielding and very simple construction. There are designs on the web for "quieting meters" and I have even seen one design where the receiver s-meter signal was summed with the quieting signal resulting in one very large dynamic range signal strength indicator. 73, Steve, K,9.D;C'I |
