All FLEX-8000 models also come standard with integrated GNSS (Global Navigation Satellite System) capability and a future integrated NTP time server. This ensures that all FLEX-8000 transceivers always remain on exactly the same frequency.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-50175 aligncenter\" src=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2024\/05\/Screenshot-2024-05-20-144341.jpg\" alt=\"\" width=\"526\" height=\"380\" \/><\/p>\n<p style=\"text-align: justify;\">The receivers are designed as direct scanning SDR receivers. They use a sampling rate of 122.8 MHz; the AD converter has a word width of 16 bits. This results in an excellent RMDR value of 115 dB (at a distance of 2 kHz). The visible result of this high-end digital technology is that the user has a spectrum width of up to 7 MHz, which is more than enough to observe several amateur radio bands simultaneously and direct their activities accordingly.<\/p>\n<p style=\"text-align: justify;\">The frequency range of the receiver extends from 30 kHz to 54 MHz, the transmitter is limited to the amateur radio bands.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The FLEX-8400 is based on the architecture of the famous FLEX-6400, but has a central processing unit approximately 4 times more efficient and an FPGA twice as powerful.
