If you want to receive a 100MHz channel , you should use a local oscillator frequency of 100-10.7MHz=89.3MHz. Then you will down-convert the frequencies of 100MHz and 89.3-10.7=78.6MHz to a 10.7MHz in...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
