28 March 2016 sideband DX propagation conditions, heard unit 522 in Sacramento CA talking to other stations, took a bit of adjustment of the tone control on the Galaxy 959 in combination with the noise filter (clipper) circuit on the Diamond TS-750 external speaker to help cut out some of the high frequency background noise. Don't forget about the tone control on your radio. Higher-end radios have these for a reason, they, combined with a decent external speaker or headphones, can really help improve the readability of weak signals, especially in SSB mode. Unsettled band conditions early this afternoon, Stateside USA American calling channel 27.385 MHz LSB (CH 38 LSB) was dead but 39 was active. Several outband/freeband frequencies above channel 40 were active with signals from California, Texas, Mexico, Central and South America as well as the Caribbean areas. 27.455 MHz USB and its low band counterpart 26.555 MHz LSB were both active with Spanish language communications. 26.585 MHz AM was also coming in nicely.
Very little domestic English language traffic heard, save for channel 6 27.025 MHz AM of course. Locals heard on the usual channels, 4 (27.005 MHz AM), 14 (27.125 MHz AM), 22 (27.225 MHz AM) and 33 (27.335 MHz AM). Truckers heard on 7 (27.035 MHz AM), 19 (27.185 MHz AM) and 25 (27.245 MHz AM). It is likely that the signals heard on channels 7 and 25 were local, as the truckers were discussing picking up loads and talking to the guard shack. Channels 2, 7, 13, 15, 23, 25, 31 and 35 are often used for this in the Richmond, VA area. Trucking companies often use frequencies outside the legal CB band for two-way land mobile communications as supplementary frequencies to channels in the legal CB band. Logged frequencies include 25.835 AM, 25.875 AM, 26.055 AM, 26.105 AM, 26.285 AM, 26.305 AM, 26.735 AM, 26.795 AM, 26.805 AM, 26.885 AM, 26.925 AM, 26.935 AM, 26.945 AM, 26.955 AM, 27.505 AM, 27.535 AM, 27.575 AM, 27.585 AM, 27.605 AM, 27.615 AM, 27.635 AM, 27.655 AM, 27.705 AM, 27.815 AM, 27.855 AM, 27.885 AM, 27.905 AM, 27.915 AM and several others.
The "low channels" - that is, frequencies below CB channel 1 (26.965 MHz) are quite popular, not only with trucking companies, but also hunters (see also, hunters using VHF marine band), fishing fleets, taxi companies, poachers, and traffickers of various things (moonshine, cigarettes, drugs, etc)...anybody who is looking for a clear frequency. AM mode is popular in the Americas but FM is popular elsewhere. Russian taxis have been heard as low as 25.165 MHz FM and make heavy use of the lower bands to escape the QRM found above 27 MHz. The low channels are generally less active then the higher frequencies (27.4 to 28.0 MHz) and many radios marketed towards hunters specifically cover the lows. These include the Connex Deer Hunter, Connex Coyote Hunter, Superstar 121, Connex SS-121, the Superstar SS-3, Galaxy DX 29HP, 33, 44V, 55V, 55HP and several other budget AM/FM radios. The market is now seeing a flood of even cheaper Chinese export radios with full band coverage 25.615-30.105 out of the box. The Deer Hunter covers 120 channels, super low, low, and mid band (CB) - 26.065-26.505 MHz, 26.515-26.955 MHz and 26.965-27.405 MHz...giving users access to the regular CB band but also the mostly vacant lower channels. The Coyote Hunter offers 160 channels, ultra-low, super-low, low and mid band CB. 25.615-26.055, 26.065-26.505, 26.515-26.955 and 26.965-27.405. The band switch is even labelled A-B-C-D with D being the CB band on the Connex Coyote Hunter, and B-C-D on the Connex Deer Hunter. This matches up with the alphanumeric band + channel scheme common throughout most export radios...a sort of "redneck interoperability".
