https://stream.echo6.co/videos/watch/a252d4fc-b93f-4dcc-bf67-46b589e079cb A contact with John VK2ASU using a homebrew 'Knobless Wonder' 7.160 MHz SSB direct conversion transceiver. The furthest known contact between two 'Knobless Wonders'. Readability was better than sounds through the camera. Both transceivers used a BD139 as the final transistor, putting out approx 1 - 2 watts. More details on the rig are at vk3ye dot com.
