The DSP-10 is an amateur-radio, software-defined 2-meter transceiver that can be built at home. It operates not only on SSB, FM and CW, but also on four Weak-Signal modes. Features are tailored to operation on VHF, UHF and Microwave frequencies. By W7PUA

This tutorial will set out the design stages required to design a theoretical microwave amplifier

Transverter for 70MHz, a project by G3XBM

Microwave parts for ham radio and experimenters.

This is a prototype of the WA4DSY 56KB RF modem. It is intended for use on amateur packet radio networks. The modem generates RF in the 28 to 30 mhz range and requires and linear transverter to convert the signal to a UHF or microwave ham band

70 MHz transverter, 4m band, by G3XBM

Amateur Radio organization specializing in VHF, UHF, and microwave communications.

Operates fast-scan FM-television in the 1.3, 2.3 and 10.3 GHz bands

Using old FM microwave equipment to operate the amateur radio 24 GHz band by EA4EOZ

A 70 MHz QRP transverter project

An article on amplitude modulation (AM) operation on VHF bands.

The 8m ISM band, a unique frequency range between 10m and 6m, holds potential for amateur radio enthusiasts, yet it remains largely unallocated. This spectrum offers fertile ground for research and self-training. The author's experience with low-power transmissions and WSPR testing highlights the band's capabilities and the need for a narrow, speech-free amateur allocation to encourage experimentation. Discover the world of 8m ISM radio exploration and its future possibilities.
