You have many more frequencies to use on the high-frequency (HF) bands, as shown in the following table. 5:1 and increases to 5:1 ant the high frequency end of that same band. I use heavy activity on the 11 meter "freeband" as an indicator of 10 meter (and VHF low band) openings. The cross-band repeat function; you’ve probably seen that feature listed in the operation manual as a function of your dual band mobile radio, or saw it as a feature in a VHF/UHF amateur radio advertisement. Soon, if you haven’t done so already, you’ll be thinking about upgrading. It is also a map showing the current location of the auroral ovals, the sunrise/sunset terminator and the regions of the world where the sun is 12 degrees below the horizon (which estimates the gray-line corridor where HF propagation is usually enhanced). These are PDF documents, available in color or grayscale presentations. a QSO) between the TX and RX sites. If you "hog" the calling frequency you will prevent others from making calls or hearing more distant stations that may appear on the. When the band is open, even know I can hear traffic every 10 kHz up into 10 meters. In addition, some higher-end CB radios are equipped with single sideband, which is a. Williams OPP/FCC November 2002 1 Sm all bands have been enl rged sli htly for le ibility. 8GHz FPV system is increasing, we now have 9 bands of 72 channels available in some VTX and VRX. frequency/meters chart. Cushcraft achieved a major breakthrough in the development of an HF multiband vertical antenna that has been specifically designed for use with a tuner and amplifier. However, most of the frequencies in this range are outside the allowable range of radio frequencies. Skip navigation Sign in.
