About 27% of these are vacuum cavitation system, 10% are remote control, and 8% are rf equipment. increased transmitter power b. All frequencies are shown as megahertz. I was ONE that this happened to. This frequency band, which began to be used in the 50's, enabled American truckers to break the monotony of long distances and to get help when they broke down; hence, the spirit of solidarity this means of communication has always tried to transmit. There are several exceptions to this "gentleman's rule" however. If you are operating on other bands, be sure to check the appropriate band plan before transmitting. Before writing my AnyTone smart CB radio review, here's something worth noting. It is therefore necessary to determine this length when designing the dipole antenna.

Below that is a broadcast auxiliary service band, the 11 meter shortwave band, and the 12-meter amateur band. An external frequency counter can be easily added using the built-in port. Below are approximations of "normal" operating RTTY sub-bands world-wide. I use heavy activity on the 11 meter "freeband" as an indicator of 10 meter (and VHF low band) openings. This shows how widespread interest is for SHTF communications. The cross-band repeat function works by using using a dual band mobile or base radio to retransmit on one frequency band a signal received on another frequency band, and vice versa. In the same way that the wavelength of a signal is the speed of light divided by the frequency for free space, the same is also true in any other medium. **Previously compared in parallel with a Bird 43 watt meter and quite accurate. 11 meter frequencies. Additionally it has a remote kill option to remotely terminate the cross band repeat. Citizens Band (CB) radio dates back to the 1940s. I understand that 10 meters and 11 meters are two different frequency bands. Good ground wave contacts were virtually impossible at times. One solution is to choose a length of wire that offers neither a particularly high or low impedance on any of the bands you wish to operate on. Once you complete the clip and test cycle the resonant frequency should be near center band and you should have an SWR curve that has equal readings at both band ends and a somewhat lower reading in the center.
