Good luck using CB channel 9 for actual emergency communications. R.E.A.C.T. moved to GMRS long ago (and its a good thing too).
Channel 9 (27065) along with 26705, 26715, 26725 and sometimes 26735, are being used as "shootout" channels by very high power Puerto Rican stations (and others, I heard Miami and Barbados in there today). Several of the stations have also gone on 27025 (Channel 6) - the original Superbowl channel, and, at least from my listening location, completely locked the frequency down when they transmit. Which can't be easy considering 27025 usually has several kW++++ power level signals on it at once. I'm hearing a station on 26715 right now that is completely readable with the RF Gain control turned all the way down. Some of these guys can be heard WITHOUT AN ANTENNA CONNECTED. Stronger than the channel 6/27.025 guys.
Who needs propagation when you're transmitting at 30,000 watts?
I'd be interested to see what some of these signals look like on a waterfall display. Several signals that are ostensibly on 26705/26715 can be heard all over the band. A S9+20db signal on 26715 showing a S7 signal strength 40-50 kHz away from the center frequency. Makes me wonder how much power is actually being transmitted on channel vs. as splatter/harmonics.

27.020 and 27.025 on my Shortwave receiver have this continuous signal that blanks out Channel 6 AM, but it's strong on 27.020. Hope it's just a "birdie" and not an actual transmission.

hi there.
this is what those PR's stations look like on my waterfall. very strong signals yes.

The 26705/26715/26725 guys (their primary frequency seems to alternate between 26705 kHz and 26715 kHz). I've heard several references to "715" or "26.715 MHz" which matches up with freebanders referring to frequencies (out of band "channels") by 3 digit frequency IDs instead of channels. 26915 AM (which is another big "freebander" channel) is almost always referred to as "915" or "26.915".
Some of the signals I've heard on in the 26700 kHz to 26730 kHz range have been so badly overmodulated and distorted that they can be heard 100 kHz away. The same can be said about the guys on 27025 kHz (and sometimes also 27085 kHz [CB Channel 11], 27265 kHz [CB Channel 26] and 27285 kHz [CB Channel 28].
