Re: Arduino Shield Kit for WSPR: Timekeeping questions

Hi Ryan
No reason not to do it this way... it all depends on the accuracy of the real time clock. If the timebase is a TCXO then it could run the U3S in WSPR mode for weeks or months.?

I am building the arduino shield kit for use as a WSPR transmitter, and I have a question about timekeeping. Now clearly, the GPS kit is great and preferred for many reasons. In addition to providing time and location it also provides frequency drift correction. But what if one doesn't actually care about those things, and only wants the?time to be accurate. There are several methods of adding a RTC to the arduino- is there any reason one of these clocks would not provide enough stability to run WSPR for weeks or months on end??
And yes I know all the arguments about not reinventing the wheel, but I can't help that reinventing the wheel is partly where I derive my joy :p
