Great bandscan Stephen. It never ceases to amaze me how strong the Santa Barbara GY stations come into San Diego County. ms

> As this radio has a dBµ meter and not a S-meter, I'm not sure how to specify those S# strengths. If I did, they'd be based (by ear) on the RST scale. S1 "faint barely perceptible" could be carrier up to program audible but isolating headphones in a quiet environment required. S4 "fair signal" would be easy armchair copy and sufficient to trip the seek/scan on a radio. S7 "strong signal" would be full-quieting (RF noise floor below receiver noise floor) and S9 "extremely strong" would be overloading the front end (severe blocking/desense - Tecsun DSP radio displaying 49/00 or 50/00 several channels off, or splatter - Sony SRF-M37W hearing signal just as loud 60-100+ kHz off). I don't recall the RST "S" scale having S+x dB, so anything over S9 would be distorting/clipping on-frequency like this: http://tinyurl.com/PL606-EC-KFMB-OvrLdDemo & http://tinyurl.com/PL380-760-KFMB-unID-20110101
> I'm guessing if I did specify the "standard" S# strengths, those clips of KFMB might be peaking at something like S9+140dB maybe? ;)
