Re: Hum on new build
Hello Curt KB5JO,
I seated the chip in the socket before I soldered the audio jack to
the PCB, and all the pins are seated properly, no rolled pins. I did
not remove the chip completely, just enough to see that the pins are
inserted okay. It is a tight fit with the audio jack soldered in. I'm
afraid I might roll a pin trying to get it back in, if I remove it
I will mess around with the kit to see if I can discover anything. I
was mainly curious to know if that hum was normal or not.
I have also hooked it up to a pair of old powered computer speakers
that have an annoying 60 cycle hum when they are plugged in, but the
distinctive background hum is still noticeable when the Cricket 40 is
turned on. Interesting, eh?
