I’m not so sure about that. The various devices are only connected to one other object. Think of this picture: A is connect to B, and B is connected to C. So, you want to bond A to B.. and don’t care about the connection to C, since it needs only be connected to B and not C. And the same

Re: [Elecraft] KIO3B Audio Spec

Hi, Here is the spectrum out of the USB codec with a -73dBm carrier from the XG3: http://ab2tc.com/new_k3s_usb.png The K3S setting is USB with a passband of 300 to 2400Hz. I left the LINE OUT level set to the factory setting (10), and set the recording level with the Windows mixer (Win7).

Re: [Elecraft] KIO3B Audio Spec

Hi again, BTW, some people have been complaining about 60Hz hum in the audio. I zoomed in one the low end: http://ab2tc.com/k3s_usb_lows.png There is absolutely no sign of 60, 120 or 180Hz in this spectrum. I have also listened to the signal with good headphones and hear no trace of hum.

Re: [Elecraft] KIO3B Audio Spec

In Knut's plot with the 1 kHz peak, the 2nd harmonic and 3rd harmonic are clearly visible. In the one with the low end, I agree, no 60 Hz, 120 Hz or 180 Hz is seen. I measured my K3S with the radio connected to the computer via the USB port. No 60 Hz, 120 Hz or 180 Hz signal observed. I

Re: [Elecraft] KIO3B Audio Spec

You'll get hum if your computer and K3 chassis aren't at the same ground potential. For many, it may be preferable to use the rear panel Line Out, which is transformer isolated. 73, Barry N1EU On Thu, Dec 31, 2015 at 2:15 PM, ab2tc wrote: > Hi again, > > BTW, some people have

Re: [Elecraft] KIO3B Audio Spec

Bob and all, Bonding to a common point may not cure hum and buzz. Follow the advice of Jim Brown K9YC and bond from equipment to equipment - following the path of the shields on unbalanced audio cables and RF coax. In other words, bond from the computer to the K3 (or from the computer to any

Re: [Elecraft] KIO3B Audio Spec

Hi Bob, Yes, the harmonics are visible but down a comfortable more than 70dB below the fundamental. There is still a little bit of junk around 3900Hz (it was there on the analog line out, too). AB2TC - Knut PS. Is a schematic forthcoming any time soon? This is the first radio I have owned

Or simply make sure the radio and computer cases are connected with an adequate bond. Why would anybody choose not to? On 12/31/2015 1:29 PM, Barry N1EU wrote: You'll get hum if your computer and K3 chassis aren't at the same ground potential. For many, it may be preferable to use the rear

Re: [Elecraft] KIO3B Audio Spec

Yes, this is correct. I have all of my station equipment bonded to the common point on the station power supply. And I do not use any "ground" to the outside world from my 2nd floor station. Works just great, all bands 160M - 23 cm, any power level to legal limit, any mode. 73 Bob, K4TAX

Re: [Elecraft] KIO3B Audio Spec

Don et al: Well Jim and I are at 100% opposite positions on this point. Bonding from equipment to equipment is a series circuit in which the voltage divides across each value of R. Thus none of the equipment will be at zero potential. By using a bond conductor from each piece of equipment

Re: [Elecraft] KIO3B Audio Spec

Zero potential is not necessarily the criteria that is to be achieved. The important point is that adjacent pieces of equipment be at the *same* potential, whether that be at zero or 100 volts potential. OK, that is an extreme example, but the point is that there should be a low resistance

Re: [Elecraft] KIO3B Audio Spec

For those of us that have external interfaces like microHam DigiKeyers the possibility of eliminating a box and the hydra cable of connections to the K3 is certainly motivation enough for the KIO3B upgrade. I am curious though how the audio performance of the KIO3B compares with other
