In this solution, we move closer to integrating the PC's audio functions into the HPSDR transceiver. This system design uses the newly available Ozy-Mini from NT-Electronics, by Gerd - DJ8AY, which has no CW key/keyer inputs. It also explores the issue of audio latency using the low latency ASIO audio drivers and VAC, Virtual Audio Cables. Packaging has improved but there is no room left over for RF amplifiers or band pass filters, so this rig will need an external amplifier such as the Tokyo Hy-Power HL-45B to be complete.
EMC
There was a concern over using an unproven power supply in this new case and also with receiver noise pick up with such compact packaging. So far it looks like the power supply and other noise pickup is acceptable with the use of many clamp-on RF filters. The greatest reductions were noted by adding the devices to the USB2 and Pennelope to antenna switch cables.
Motherboard
This system uses the new Intel Atom 330 dual core CPU, but this time we selected a new non-Intel MotherBoard with BlueTooth.
