Re: [Elecraft] What's best Soundcard Interface for KX3

George, check that Data is set to DATA A. (Change it using the VFO B knob). Also widen the filter passband when in DATA mode and it should work. Also make sure that you have DATA A set to USB and not LSB ( Hold ALT to change it from one to the other). There are advantages in DATA rather than

To be clear, the SLUSB VOX is the weak point if it is used for PTT. It is not reliable... this has little to do with the radio of any brand. Rick PS Congrats on the 160M VK0EK QSO, I know what an effort that was, I saw your call on DXA3 just after. On 4/10/2016 10:58 PM, Jim Brown wrote:

Re: [Elecraft] What's best Soundcard Interface for KX3

Bob, While your decode level is admirable, using the SLUSB VOX to trigger the PTT is less than reliable. You will be FAR better off using a CAT command (or RTS/DTS) for PTT. However on my K3, I do set the tx volume to max on the sound card driver, the TX knob to noon, THEN adjust the ALC

Re: [Elecraft] What's best Soundcard Interface for KX3

George, So use the 1st option until you can get the plugs and jacks to construct the adapter. For VOX, just set VOX on - hold the button just to the lower left of the VFO A knob. It is a per-mode setting. Are you using the correct DATA sub-mode? There are 4 and you should be using DATA

Re: [Elecraft] What's best Soundcard Interface for KX3

George, Not sure how to set up VOX using an internal sound card. For use with my SignaLink USB, I simply adjusted the output level of the sound card until it properly keyed the transmitter. Also Chapter 6 in the Elect KX-3 manual covers VOX setup. See page 66. I am also using USB rather

Re: [Elecraft] What's best Soundcard Interface for KX3

George, That is great. -24 dB is good for a built in sound card. By the way what version of JT65 are you using? Note that your transmit signal level is usually critical for JT65 and JT9. Also, I always use VOX to key the transmitter. 73, Bob Nobis - N7RJN n7...@nobis.net > On Apr 10,

Re: [Elecraft] What's best Soundcard Interface for KX3

George, You are making progress, receive is good - only a little more to go to handle the transmit situation. The cause is because the ring contact on the microphone jack is PTT, and the unused channel (right) of the soundcard has a sufficiently low impedance (resistance) to trigger the

Re: [Elecraft] What's best Soundcard Interface for KX3

The IQ outputs are for displaying the received spectrum on a pan adapter like the PX3 or other spectrum display software like NaP3 through the sound card in the computer. The audio output at the headphone jack is for feeding audio to digital mode software like FLDigi or MixW to work modes like

Re: [Elecraft] What's best Soundcard Interface for KX3

John, That is mixing apples and oranges. The RX I/Q is a quadrature output that can be used as input to a panadapter software application or to the PX3. Yes, it requires stereo for those applications. They can display up to a 200 kHz slice of the band (if the bandwidth of the soundcard is

Re: [Elecraft] What's best Soundcard Interface for KX3

On the topic of sound cards, I was wondering what the advantages are to using the IQ output of the KX3 as opposed to feeding the headphone jack into the input of the soundcard? I believe the IQ output requires stereo input to work, but what are the advantages? I have seen on this list quite a

Re: [Elecraft] What's best Soundcard Interface for KX3

George, Many laptops do not have a good quality built-in sound cards. Their performance for very weak signals typically is not as good as using an external sound card. You might want to test your internal PC sound card before you go to Brazil. If your internal sound card is able to

Re: [Elecraft] What's best Soundcard Interface for KX3

George, You laptop may have only a mono input for the mic/line-in, but for digital modes, only one channel is used, so it should work - just be sure to turn off sounds from your OS so those are not transmitted on the air. A simple and inexpensive USB soundcard can eliminate the problem of

Re: [Elecraft] What's best Soundcard Interface for KX3

My whole KX3 station, antenna wire and all, fits in an ammo can. The Creative Labs SB X-Fi Go! fits in just fine along with a couple of 3.5mm m-m cables. The X-Fi is a small USB dongle, about the size of a flash drive. It's a good compromise between size and performance, and it isn't

Re: [Elecraft] What's best Soundcard Interface for KX3

George, You may not need any interface at all. You may be able to use the internal soundcard in your computer. If you do that, turn off sounds generated by your computer OS. The other alternative is an inexpensive external soundcard. Use VOX to transmit instead of PTT. It simplifies the

Re: [Elecraft] What's best Soundcard Interface for KX3

For portable operations with my KX3, I use the SignaLink USB, mainly because of its small size. There are better performing sound cards, but for compactness and ease of use the SignaLink works for me when I travel. 73, Bob Nobis - N7RJN n7...@nobis.net > On Apr 10, 2016, at 09:41,
