QFH antenna for weather satellite band - This article describes how to make a quadrifilar helix (QFH) antenna easily, from inexpensive materials: uPVC plumbing pipe and RG-58U co-axial cable

A 16 Turn S-Band Helix - This design represents the smallest practical antenna for Oscar-13 mode-S. Perfect beacon reception at all times is possible, and acceptable SSB even at 43,000 km range.

13 cm Helix Antenna  ^pop - Here is the design of a 2.4 GHz antenna that is ideal for amateur satellite communications. This antenna is easy to assemble because the design itself tolerates inaccuracies in the construction without really affecting performance.

Handi-Tenna portable satellite antenna - Here is a high-performance hand-held beam antenna that is easy to build and guaranteed to improve your downlink from the LEO satellites over ANY rubber duck or mobile whip

Psk31 - PSK31 is a digital communications mode which is intended for live keyboard-to-keyboard conversations, similar to radioteletype. Its data rate is 31.25 bauds (about 50 word-per-minute), and its narrow bandwidth (approximately 60 Hz at -26 dB) reduces its susceptibility to noise.

G4ILO Receiving weather satellites - If you are interested in the environment, the weather and other natural phenomena then there is something magical about being able to see pictures of the earth from space just as it is right this minute. One way you can do this is by receiving images from weather satellites.

NASA - Science@NASA J-Track Spacecraft - The official NASA tool for orbital tracking of the International Space Station and the Space Shuttle is available through Human Space Flight's Orbital Tracking web page. Shuttle and Station tracking will be removed from J-Track in the near future, but many uncrewed satellites will still be available for tracking

Low cost frequency stabilisation - The Icom IC-746 is quite a popular HF/VHF multimode transceiver which has one shortcoming in its standard configuration when used to operate modes requiring good medium-term frequency stability.
