144 & 432 MHz High IIP3 PA3BIY LNAs
When I first saw the article in , I was very impressed with the data and quality of the construction
222 Mhz Transverter for the FT-817
The transverter can be configured to work with the Flex-1500 SDR and other transceivers with transverter ports
50Mhz high gain antenna and masthead preamplifier
An efficient antenna system is a prerequisite for more successful six metre operationv
A Motor Drive for your Variometer
Everyone who has set up a low frequency base loaded antenna is aware of the very narrow bandwidth of the antenna system, and the seemingly constant need to retune the antenna
