A 13cm down converter by PA4DAN
To receive ATV signals in the 13cm band I designed a down converter.
I intended to use a LO-frequency of 3.36 GHz, but after trying some oscillator designs I found out that oscillating is much harder at 3 GHz than at 1 GHz. So I changed my plans and build a 1360 MHz oscillator.

A 2.3GHz to 432MHz receiver converter by DL5NEG
It is a very small receiver converter that can be plugged to the backside of the battery powered portable transceiver FT817 from Yaesu. It runs on the batterys of the transceiver (no changes to the transceiver necessary).

An S-Band to 70cm Receive Converter for Phase 3D by GØMRF
A recent survey of satellite users world-wide revealed that only 3 percent were active on mode S. With the re-entry of Oscar 13, we will have now sadly seen the end of a mode S transponder that has given years of reliable service ...
