26605 AM Spanish language

Tuning into 26605 AM on the Dominican Republic SDR, and hearing beeps and Tequila in between and OM speaking in Spanish.

26.605 MHz is another popular one for Latin America, especially Mexico but I've heard Dominican Republic on the "low band" channels (26515 to 26955 kHz / 26.515 to 26.955 MHz)...often you'll hear music and noise toys playing various recordings over each other. 

I remember seeing a video on YouTube a while back about a Mexican CB shop doing modifications for Cobra 29s and similar AM only rigs to give them 80 channel capability, channels 1-40 were the regular 40 CB channels, and channels 41-80 were the low band channels (skipping the "A" channels 26.545 MHz, 26.595 MHz, 26.645 MHz, 26.695 MHz and 26.745 MHz) and following the same out-of-order channel steps for channels 23, 23, 24 and 25 - so that the 80 channel rigs would "track" with export radios operating on the low band or "down one band". 

Latin American truckers are just as likely if not more likely to have the capability to transmit out of band as American truckers are, and let's not forget the Mexican taxi companies using out-of-band frequencies as their own land mobile radio service for taxicab dispatch! 

It is also possible that you've stumbled upon a local freeband channel, presuming that the nearby watering holes (26.565 MHz, 26.585 MHz, 26.705 MHz, etc.) were quiet but 26.605 MHz was active.

You could be right, I possibly might have stumbled upon a freeband channnel.. didn't hear them yesterday but maybe I will try later on

Certainly worth a try.  If CB is popular enough in the area of the Dominican Republic where the SDR is located then there's another reason for operators in that area to want "their own channel".  Would you be able to send me the link to the remote SDR you're using in a Private Message?  I'd be interested in tuning the 11 meter band on that receiver as well :D

I'm fascinated by all the different things the 25-30 MHz spectrum is used for and one of those is how in other countries there is extensive use of out-of-band frequencies for land mobile radio purposes by trucking companies, taxicab dispatchers (and taxis in general), logging/forestry and other purposes in places of a [more expensive] "proper" VHF/UHF land mobile or business radio system.   It's likely cheaper to set up a base station with a halfway decent antenna, install export radios in all your mobiles and pick a clear freeband frequency instead of going through the hassle of getting a license and setting up a VHF/UHF business radio system.  One of the original purposes of the CB service was a "poor man's business radio" and that's just what its used for in a lot of places.

I've tuned through the 11 meter region on European and Russian based SDRs and have noticed extensive use of frequencies between 27.405 and 28.000 MHz (especially in Russia) for taxicab communications in FM mode.  These systems are using CB channel like frequencies (27.775 MHz, 27.725 MHz, etc) so chances are they're using export rigs.  There's also the taxicab company somewhere in Mexico that uses 27.515 MHz AM and can be heard during band openings.  The 25.615-26.505 range (band A and band B on export radios) is filled with taxi dispatchers out of Latin America during band openings as well.
