There are two parts to this: the correct sideband, and the correct frequency. On the K3/K3S, CW is on lower sideband, and CW-REV is on upper sideband. On bands where you use LSB for SSB, switching to CW will still be on the correct sideband, but on bands where you use USB for SSB, you will

Re: [Elecraft] K3 5 pole vs 8 pole filters - attenuation in the passband

My solution for this is to configure the K3 to switch the 250 Hz roofing filter in at 350 Hz. A DSP filter of 250 Hz is a bit narrow, but with a 350 Hz DSP setting and the 250 Hz roofing filter, I still get good copy. That being said, most of the time I operate RTTY with a 500 Hz roofing

Re: [Elecraft] K3 - AFSK anamoly? No replies, try again

Don, as described that was NOT the opposite sideband. On the video the stronger signal was at 14091.883 kHz on the dial. That is the frequency of the mark tone; the space tone would have been at 14091.713 kHz. The pitch in use was 915 Hz mark, so the suppressed carrier frequency would be

Re: [Elecraft] K3 KIO3B - FSK - stereo

Most media players use the default device. In addition to Windows sounds, you wouldn't want sound clips from your Internet browser playing through the radio codec, to pick an example. Another reason might be that if the K3S or K3+KIO3B is turned off or disconnected from the computer, the

Re: [Elecraft] K3 KIO3B - FSK - stereo

Here is something to check: Right-click the speaker icon in the Task Bar and select Recording devices. In the Sound window select the USB Audio Codec and click on Properties. In the Properties window click on the Advanced tab and check the Default Format. If it is set to 1 channel, ... change

Re: [Elecraft] Using K3 with HRD

The PC speaker is connected to the PC's internal sound card. For data modes you said you are using the USB codec in the KIO3B, which is not connected to the PC speaker. Try using a speaker connected to the K3's SPKR output (or the internal speaker) to monitor the audio instead. You can adjust

Re: [Elecraft] K3S and RTTY Contesting with N1MM+/MMTTY

There is some confusion evident in your post on the roles of the connections between the radio and the computer. There are three separate connections needed for operation in data modes (possibly four in FSK). The first of these connections is for rig control from N1MM+. On a K3, this is the

Re: [Elecraft] K3S Computer Audio Question with Sub RX installed

Fldigi versions since 3.22.06 have the capability of decoding from either the left or the right channel of a sound card. You can use a command-line argument to tell fldigi which configuration files to use You would run two instances of fldigi with different configuration files, one configured

Re: [Elecraft] KY Command

On January 7, NR4C posted a function key message file for N1MM+ that used KY commands to send FSK RTTY without requiring any FSK keying interface connected to the K3/K3S AUX port. While the basic idea (<04> used to terminate transmissions) is good, unfortunately there is an error in this file.

Re: [Elecraft] VOX / PTT combination on k3

Once you have enabled VOX, you are stuck with whatever delay it imposes. In effect, the VOX and PTT functions are in a logical OR relationship - if either one of them wants the rig to be in transmit, it will be in transmit. In your current setup you could disable computer PTT control entirely

Re: [Elecraft] Disappearing Line Out Audio for Sub Rx

I am wondering why you would want to use Diversity mode in RTTY, and how you would actually make use of it. Diversity mode works by feeding two slightly different signals into a single brain that is programmed from birth to cope with two such inputs (two ears) and synthesize them into a

Re: [Elecraft] [K3] Recent post about n1mm macros to send FSK without fancy hardware

In N1MM+, use the macro {CAT1ASC KY text;} to send "text". Spaces and ; are significant - see the N1MM+ on-line documentation and the K3/KX3 Programmer's Manual. You can insert N1MM substitution macros like #, * and ! as long as the total length of the text to be sent stays below 24
