Initial Power On Test

"aa4rh"
 

After a year and a half I am finally starting construction of my 30 meter QRSS beacon. Right away I came up with a question. I installed the Atmel microcontroller and C12, attached a set of headphones, and powered the unit up. I hear my call sign one time and then a very slow series of tones separated by long periods of silence. My call sign is never repeated. If I disconnect and reconnect power, the same sequence starts all over again.

This is not what I expected. I thought that during the test my call sign would be repeated continuously, which is what I thought QRSS is all about.

My question: When the circuit is complete and the speed is set to 3 second dots, or slower, does the microcontroller have enough "smarts" to recognize that it should send my call sign repeatedly?

I don't want to continue with the construction until I'm sure that the microcontroller is working properly.

Thanks for any replies,

Richard,

This is completely normal behavour. First power up sends your callsign at 12 wpm...after that at QRSS speeds. The slow tones are morse, 3 second dots or longer.?

RIP Dennis Richie, I'm sure you will still be cutting code somewhere out there in the universe. You gave the world "C" and taught me a lot.

If you listen long enough Richard, (I haven't timed it) your call will be sent at 12 wpm again. The sequence repeats every 10 minutes or so.

I've tested two with the same results. W4GFA and mine, WT4C.

Thanks guys! That answers my question. I should have figured that out on my own.

I ordered new NP0 capacitors from Digi-Key and when they arrive I'll be able to finish up. In the meantime I'll be winding the inductors and further populating the board. Actual on-air testing may take a while since I live in an apartment for now. A balcony antenna may be a possibilty.

Regards,

Richard
