Welcome to UHF-Satcom.com



The number one Internet resource for satellite and spacecraft downlink frequencies and information.



On this site you will mostly find satellite and spacecraft related information concerning various RF downlinks from VHF to Ka band (up to about 40GHz), along with ideas and techniques for receiving or detecting these signals.



Use the menus above to select your area of interest. Frequency lists are contained under the satellite reception topic and will help you to identify signals you may have detected. If you have found anything which is not listed in our database please email it in and it will be added.



This site was originally started back in the late 90's by Ivan HA5TS (RiP) and Paul M0EYT to consolidate satcom monitoring related information into a single place. If you need real-time answers to questions, please join our #hearsat IRC channel details of which can be found below.
