The term ground has always been used to refer to the common tie point in a circuit. For example the shape on the schematic with the three little horizontal lines is referred to as a ground symbol. But that has caused no end of confusion. Contrary to widely-held belief, in 99% of cases it is

Re: [Elecraft] P3 Beta software Bug?

2014-04-25 Thread Alan Bloom
One change in the beta firmware is to make the width of the transmit cursor in Data A mode equal to 2.7 kHz. The reason is that in Data A mode there is no way for the firmware to know what the actual bandwidth is - it can be whatever is coming out the PC's sound card. So rather than assume

Yes, the I/Q signal from the KX3 goes through an analog buffer directly into a two-channel analog to digital converter. All processing is then done digitally by the DSP. Correcting the frequency response is a simple matter of multiplying the frequency points by the correct number before they

The P3 reads the K3 preamp and attenuator settings and adjusts its gain accordingly for accurate amplitude display. The K3 can be set to either take ATT/PRE into account to keep the S meter reading the same, or not, depending on the SMTR MD menu setting. If set to NOR, that can be one reason
