Since the first post on the OpenRadio project Mark has been moving ahead and leaps and bounds. In just a few late nights work he has assembled and tested the radio, managed to receive off air signals, and even tested the PSK31 transmitter! Fine business Mark.
Hooked it up to a real antenna tonight:
That’s me decoding actual 20m PSK31 signals!
Signal path is:
Antenna —RF—-> OpenRadio SDR —-IQ–>|Laptop|—-IQ—> Spectravue
(IQ Demod) —SSB—> fldigi
Mark managed to build the radio in 1-2 hours, including taking plenty of photos to document assembly and aid others. Now not everyone will have Mark’s radio assembly skills. However even allowing for a learning curve and a few coffee breaks we are on track for a one-day (say 6 hour) mini-conf assembly time.
A working prototype verifies the hardware design, so we are now getting ready to re-spin the PCB and start putting the kits together.
In other news Edwin from Dragino has added the OpenRadio kit to his store. We estimate the kits will be available for shipping in December. Kim, Mark and I, are still deciding if we will bring a bunch of kits to LCA, or have delegates pre-order them from Dragino. More on that shortly.
