VHF/UHf

摘要

These days the Internet plays an essential role in the compilation of the 'VHF/UHF' column. Norman Fitch describes the sources he uses to bring us the latest VHF/UHF news every month. The Internet plays an essential part in the compilation of 'VHF/UHF' each month and long gone are the days when almost all the contributions came by the post or 'snail mail' as we now call it. So, as there are few activity reports this month, I thought it appropriate to review some of the data that are available on the Internet. There are four main sources of information. 1) Your e-mails. 2) The official websites of organisations like the NASA, the RSGB, the ARRL and so on. 3) Your personal websites and 4) The websites of the thousands of special interest groups such as contest operators, satellite, repeater users and researchers.
