11 meter / CB opening 6 August 2019
« on: August 07, 2019, 1032 UTC »
Recorded yesterday afternoon around 6:30pm local time (2230 UTC)

Lots of AM activity on in-band legal 40 CB channels on several online SDRs, and the usual freeband frequencies, 26.665 MHz, 26.685 MHz, 26.716 MHz, 26.735 MHz, 26.775 MHz, 26.785 MHz, 26.805 MHz, 26.815 MHz, 26.835 MHz, 26.885 MHz, 26.915 MHz, 26.925 MHz, 27.425 MHz LSB, 27.435 MHz LSB, 27.465 MHz LSB, 27.505 MHz AM, 27.525 MHz AM, 27.605 MHz LSB, 27.615 MHz AM, 27.665 AM, 27.745 MHz AM and 27.775 MHz AM.

In-band the usual suspects in AM mode: channel 6 (27.025 MHz), channel 11 (27.085 MHz), channel 12 (27.105 MHz), channel 15 (27.135 MHz), channel 19 (27.185 MHz), channel 20 (27.205 MHz), channel 22 (27.225 MHz), channel 26 (27.265 MHz), channel 28 (27.285 MHz), etc.  SSB DX on channel 37 (27.375 MHz LSB), channel 39 (27.395 MHz LSB), channel 40 (27.405 MHz LSB, with AM mixing in, of course)...and, naturally, channel 38 (27.385 MHz LSB) was very busy.

Locally there was a lot of activity on 11 meters...including channel 38 LSB booming in at points.  I got three videos, with three different radios!

Galaxy DX 959

CRE 8900 (aka DR-135CB)

Superstar 3900 (aka a dozen other names and models)

Note the activity on 27.435 MHz LSB, midwestern accents on 27.435 LSB and several other SSB frequencies/channels, including channel 38 LSB / 27.385 MHz LSB.  On the second video (the CRE 8900) I caught some CB operators using R/C channel 19A - 27.195 MHz - for AM voice communications.  Channel 19 was messy, which explains use of the +10 kHz switch.  27.195 is pretty popular.

I actually make a point of dropping the RF gain down while monitoring 27.025 AM on the Galaxy 959.  I had to adjust the RF gain on the CRE 8900 just a bit to reduce some of the background noise...sometimes that radio (itís an early production version) does better with the RF gain at 75% or 80% instead of 100%.  I was able to drop the RF gain all the way down and still hear the stations on channel 6.
