A 1 dB attenuator would have next to no effect. As it turns out, this is a 30dB attenuator
with 1W power handling. This is probably higher than the PSR600 global ATT (would need
to check specs). In any case you don't get the choice on a channel-channel basis with
an inline attenuator. So.. with 30dB I'm scratching my head as to why there is no effect on
weaker signals, or why it should work better than the internal one.

You're right...I goofed. Thats the wrong Ebay link. Mine was a 1 db attenuator. Not a 30 db. But as I said, the 1 db did the job for me. I'm not in a high overloaded area with strong transmitters nearby. The 1 db was just enough to cut the slight overload I would sometimes get, eliminating the need to activate the scanner's built-in ATT any more.
