Re: uBit's First Words "Birdies"


 

Mike, I would suggest that You first try the opriginal i.e. Raduino to see where the birdies come from and then start experimenting.

Got volume control hooked up this morning.? Used RG174 to top of the pot and wiper.
With a couple of feet of wire for an ant.? I fired it up.
I get lots of "Birdies" singing everywhere.? I can detect the Tuning noise from the past.? But very slight, volume full up.
I just heard a guy at 7.185.? Donald Duck sounding.? I could not clear him up.? Must be running big power and ant.? I am in a concrete walled house.? AM radios don't like it here!? BitX never hear any station in here.
Huge Birdie at 7.120,?? Big!
I have the Mega Pro running on the new RaduinoXP.?? It has all the good supply filtering.? I do have to drop the resistor value into the 7805 Regulator.? I used 47 ohm, OK on Nano board but the Mega Pro draws more, the regulator is near drop out.
So what a folks saying about Birdies?
I may separate the Mega XP board temporarily and shield it with a zip lock bag and al foil?
Maybe I am hearing it?
