Re: Bitx40 very loud, high-pitched, low frequency noise


Thank you so much for your help Woody! I'll try to get my hand on a small ceramic cap and let you know if this resolved the problem. I'll also try to salvage the ferrite sleeve from an old cable. I'll also try to power the bitx using 8 AA batteries as a constant DC source to check if the problem is even related to the power supply. Hopefully 8 AA batteries will allow for at least a couple of minutes of RX operation.
