[Elecraft] [Bulk] Re: KX3 Internal soundcard

[David Anderson]

The KX3 with PX3  is my primary shack transceiver which is dedicated to 2m DXing.

(I use an external transverter). 

As I need to be able to switch between Data (WSJT)and SSB/CW frequently and didn't want to be constantly plugging and unplugging mic and speaker leads here is what I did:

For the receive audio I used a Behringer HA400 4 channel stereo headphone amplifier which feeds stereo headset, powered stereo speakers and soundcard. Problem solved. I can leave the KX3 audio gain at a fixed level and control individual levels on the headphone amplifier. I can monitor receive audio while on Data etc.

For transmit audio I built a switch box which has a switch to change from Soundcard (Data) or Microphone ( switching audio and PTT) . I also have a switch to choose either headset boom microphone or another desk (or hand) microphone. I have a footswitch for PTT when using the headset boom mic.  It was half a day's work to make this neat plastic box with a couple of switches and 3.5mm sockets. 

A nice feature of having a mic/soundcard switchbox  is that when in Mic position there is no possibility that when I boot up the computer that the PTT of the transceiver gets pulsed on and off.

It would have been great is there had been extra switching and sockets for doing this in the KX3, but I realise that it is a portable radio and there have to be some compromises to make it so. I am just amazed what Elecraft have been able to squeeze into it.

However, I won't ever buy another transceiver that doesn't have a dedicated Data jack, even if it does say Elecraft on the front.  I find it a pain to be constantly unplugging cables and inserting new ones each time I change modes.  I'm afraid of wearing out the 3.5mm jacks on the KX3 with all the inserting in and removing of plugs.  I know I can use Y-adapters, but that only adds to the considerable mess hanging off the side of my KX3.
