70 MHz Transverter

This band is not allocated in OE (yet?), therefore with some good luck only I succeeded to get a 70MHz transverter from Microwave Modules of Liverpool. This producer was well-known in the 1980s for their amplifiers and transverters. Many of these are still working, and appear on the second-hand market. These were constructed inside a compact Eddystone diecast box with either BNC or SO239 sockets for RF interconnections and a 5-pin locking DIN connector for DC and switching connections.  Manual

Models were produced for use with 144MHz transceivers as well as HF transceivers using a 28MHz IF interconnections and a 5-pin locking DIN connector for DC and switching connections. Models were produced for use with 144MHz transceivers as well as HF transceivers using a 28MHz IF. They have been proved to be quite robust units over the years with many proving useful for both portable and home station use. They produce around 10W output and are suitable for all-mode operation.
The input power required to drive these units is around 0.3 Watts: they were originally supplied with an external 15dB power attenuator, which dropped the output power from a 10W transceiver to a suitable level.
Microwave Modules produced some new models in the mid-1990s, which are reputed to have a much better performance than the originals.
