This mode turned out to be even simpler to implement on anĪrduino than CW, and the project gets me one step closer to my goal of havingĪn open-source, multimode digital interface for HF that can be run completelyįrom battery, and does not require a PC with a soundcard. Project, so I thought I would try another digital mode - this time, This approach worked quite well for the CW modem Squeeze out of a microcontroller such as the Atmel AVR, upon which the Arduino Have successfully used small low-power computers for modes such as BPSK31 andĬW, so I have been working to see how much digital mode functionality I can Where a simple text-to-mode interface would be more than sufficient.

Is indeed impressive, it is a bit over the top for casual or portable operating, While the DSP capabilities of these packages Unfortunately, the modern sound-card-mode software requires ever-increasingĬPU power to run accepably. Receiver, without one more watt of power consumed! That would give me nearly three S-units of improvement at the other guy's Much rather run the computer and interfaces "on QRP," and then haveĤ00W of input to my transmitter, giving me a 200W signal on the air.

I see no reason to run 5W or less from the transmitter, when the PC used forĭigital modes or logging burns 400W or more, even when idling. Power I have into the transmitter, or into the longevity of operation.

If I ever found myself operating with a power budget, I would rather put the

Their idea of optimizing the power budget of a radio station. Patient enough to do QRP at the moment, but I am taking some inspiration from The guys who fly gliders, the QRP community continues to master the art ofĭoing more with less, and I admire their accomplishments. To be honest, I think the idea of HF QRP is very interesting.
