Re: [Elecraft] K3 ACL setting for PSK31
Haines - To amplify on my previous email - I will assume your 400hz filter occupies slot 5 and the 2.8khz filter occupies slot 3. In the CONFIG menu, select FLx BW, where "x" will be a number 1 through 5. *Select filter slot 3 by pressing the "3" button on the keypad. *Be sure the BW (bandwidth) is set to 2.80. *Select filter slot 5 by pressing the "5" button on the keypad. *Be sure the BW setting is 0.40 Using VFO B knob, change the menu selection to FLx ON, where "x' should be 5. If not, press the "5" keypad button. *Cycle through all the mode settings with the "mode up" (or "mode down") button, and be sure that "YES" appears for CW and DATA, and "NO" appears for all other modes. *Change the filter selection to the 2.80khz filter by pressing the "3" keypad button. *Cycle through all the mode settings as before. "YES" should appear for all modes. "YES/NO" is selected with VFO A. Using VFO B, select the FLTX MD menu item, where "MD" will be "SB", "CW", "AM", or "FM". (Data mode uses the SB setting) *Cycle through all the modes as before. Be sure filter 3 is selected for SB and CW modes, and AM and FM are unassigned (they require special filters for transmitting) This selects the filter used for transmitting. That should do it. Indeed, I can increase the width by adjusting the DSP BW width, but only to a small degree. As for the filters, I installed the 2.8 kHz and 400 Hz filters, and apparently assigned the 400 Hz to data modes. But as I indicated in my other message, I'm having trouble switching the data mode to use the narrower filter to see if that makes the waterfall the right width. Put the radio in TX TEST mode and hit the software TX button to send audio to the K3. Now adjust using the MIC gain control (sets the line in level) for 3-4 bars ALC. If you are not getting any ALC reading your soundcard output may be set too low. Try increasing that and try again. I have good success with the soundcard output set to about 20%. Here I'm stumped. My directions for setting ALC in general are different than setting it for DATA and nothing for DATA speaks of putting the K3 in to TUNE mode. When I do hold the TUNE button to enter TX TEST mode, my display shows that I'm set for about 20 Watts and that I'm using FL2 (the 400 Hz) filter, but now the mode on the display has changed to CW. If I exit TUNE, I'm jumped back to DATA mode. While in CW, the ALC reads 7 bars, which is too much for DATA. The TX TEST mode allows settings to be made without generating a signal. You can make the setting while transmitting, you just need to identify. My mode does not change when I press "TEST" for 2 seconds - put the K3 back in Data A mode if that happens. Your lack of output can result from several factors: *Sound Card Output setting too low *Line In gain setting on the K3 too low *Faulty filter setup, which we corrected above *Faulty cable connecting sound card to K3 When I do software TUNE in my fldigi, while in the K3 DATA mode, there's nothing registered on the ALC scale. Be sure you are in DATA A mode. Press "AFX" (DATA MD) for 2 seconds, then select DATA A with VFO B. DATA mode will not accept sound card input. Good luck - let me know.

Re: [Elecraft] K3 ACL setting for PSK31
Haines, To adjust the audio gain, you set the K3 into TX TEST mode (hold the MODE^ button), not TUNE. TX TEST allows you to adjust the transmit controls without actually transmitting RF. Check to be certain your soundcard is actually producing audio - check the soundcard controls in your computer as well as the input gain control in the K3. Turn the MONitor volume up and you should hear the tones in the K3 speaker. Be certain the K3 MIC SEL menu item is set for the input that you actually have the audio plugged into (LINE IN, Front panel mic jack, or Rear panel mic jack). The K3 TUNE button places the K3 into CW transmit state and emits RF at the level preset in the menu. It is entirely different than TX TEST. On your filter problem - read the manual again and be certain your filters are set up correctly. You must select the 2.7/2.8 kHz filter for data transmit. On receive you may use any roofing filter and DSP combination that you choose. The waterfall will only show those signals that pass through to the audio, so even if you have the 2.7/2.8 roofing filter selected if your DSP filtering (width/shift or Hi-Cut/Lo-Cut knobs) is set for a narrow passband, that is all that will show up on the waterfall display. I like my DSP filtering set for a 400 Hz width with a center frequency of 1.50 kHz, so I tune near the desired signal with the VFO knob and then click on it in the waterfall display to tune precisely - YMMV, If you desire something different, you may set the values you prefer, the K3 allows you to do that. 73, Don W3FPR Haines Brown wrote: ---snip--- Here I'm stumped.

I don't know why you're having trouble selecting it though. But that's sure to be the reason you aren't seeing any output, as your audio signal may not be coinciding with the filter passband. It's fine to have the narrow filter selected as well. Then you can select it on receive using the width control. The wide filter will always be used on transmit. You should not be using the TUNE button on the K3 front panel to adjust the drive level. As you have discovered, it puts you into CW, key down mode, so you can twiddle the controls on an external ATU. You should use the Tune option in your sound card software, Fldigi. That should put the rig into transmit and send a pure sine wave. You can then adjust the line input level until you get a steady 4 bars on the meter. If you don't get anything then either the SSB filter isn't assigned, or you haven't selected LINE IN for the input, or there is something wrong with your computer to K3 audio connection. I take the point about the Linux version of the updater not being as up to date as the Windows version. But I don't think there is anything that prevents it from being used to upload the latest firmware. The reason you aren't seeing 2.57 (or now 2.58) is because that is a beta firmware not a release version. To get it you have to follow the instructions on the website to manually download it to a folder on your computer, and then point the updater at that folder. - Julian, G4ILO.

Re: [Elecraft] K3 ACL setting for PSK31
It was my impression, based on two sources, that for PSK31, it was best to use the 400Hz filter (FL2 in my case), not the 2.8kHz (FL1 in my case) filter. Was I wrong? You must use either a 2.7 or 2.8khz filter for transmitting all modes except AM and FM, which require separate filters. The bandwidth displayed on your waterfall is discretionary - I like a display of 2.5khz or more so I do not miss any signals. If a very strong signal is controlling the AGC, I try to get it outside the pasband by changing frequency. But to check, I went to change to the 2.8 KHz filter for the data mode, and so while in data mode, went to the config menu. and changed FL2: ON to NO, with the aim of then setting FL1 ON to YES. However, the configuration menu does not have FL1, so wasn't able to test whether my problem is that I should be using the 2.8 kHz filter. You need to see which filter slots are occupied in your K3. The recommendation is to put the narrowest filter in slot 1, building up to widest filters in slot 5. Slots can be left unoccupied and do not have to be used consecutively. You can turn ON any number of filters for receiving, but only one filter for transmitting. The latter must be the 2.7 or 2.8khz filter, and you designate it by its filter slot number. You should activate all filters for CW and data mode reception; all filters of 1.8khz or wider for LSB, USB, and AM reception. Others will differ on this suggestion. No, but I assumed that the installation utility might be designed for the operating system, and its development for Linux was slower than for Windows. I don't think the Linux firmware loader has a filter assignment tab. This makes it easier to set up the filters. So you will do it in the CONFIG menu on the radio. It will load all firmware versions into the K3. When I run the k3util utility and click Copy New Files from Elecraft Server, the new files are downloaded to the ~/Elecraft/K3_Firmware directory. However, the downloaded files are the MCU 2.46 that came with my K3, not the newest firmware, MCU 2.57. Version 2.46 is the latest "released" firmware, and so is the latest version directly accessible by the firmware utlity. Versions since that one are "beta" software, still under test but usually fully operational. Features get added first to the "beta" versions, and then subsequently are blessed as "officially released". To find the "beta" software you need to set your internet browser as specified on the Elecraft website's download page. It can not be downloaded by the firmware loader.
