Re: [Elecraft] [K3] autotuner for K3 with AL-811 amp (KAT500 or other) / random wire antenna
Same thing here except my doublet is a stealthy Extended Double Zepp cut for 80 meters (340' long). Works on all bands (6 countries on 160; 200+ countries on the other bands)... 100' of 450 ohm line, 4:1 common mode choke, some coax and the K line is happy. I just wish the oaks were taller, 30' above dirt just isn't enough height.

John, Don's suggestion is for sure the way to go. My K3, KPA500, and KAT500 sit next to each other on my desk. I run about ten feet of RG-8 to the outside where I have my 4:1 balun, and then 110 feet of 450-ohm ladder line to my doublet at the other end of my property.

Re: [Elecraft] [K2] C22 has no effect
Thanks for setting me straight, Don and Mike. I think have the hang of it now...calibration is much better now - though I still may want to refine it a bit. Though, I didn't seem to be able to make the N6KR method work on WWV at 20 MHz - couldn't get a frequency match.

Re: [Elecraft] PA HOT
Ed, The most common reason for CAL TPA going to 255 is that the K2 was powered on when the heatsink temperature was below 0 degC. Since the DAC values do not go negative, in the 8 bit world, the next number lower than zero is 255. 73, Don W3FPR On 11/6/2014 4:14 PM, Eddy via Elecraft wrote: I've seen this error before.

Re: [Elecraft] [K2] C22 has no effect
Steve, C22 has no effect on the received frequency or the beat note during normal operation. The setting for C22 is only used during a run of CAL PLL and CAL FIL when the frequencies (actually equivalent DAC values) are stored in EEPROM. Once that has been accomplished, the 4 MHz reference oscillator serves only as the clock for the MCU and for that function, the exact frequency is not important. If you want to do a calibration run on your K2, I suggest you review the K2 Dial Calibration article on my website www.w3fpr.com. 73, Don W3FPR On 11/6/2014 3:50 PM, Steve Kavanagh wrote: I just acquired a second hand K2 (my second one) and upon going thru the operation in detail I noticed that it was somewhat off frequency.

At HF, there will be little loss in that 15' run. 73, Don W3FPR On 11/6/2014 11:47 AM, John Shadle wrote: Hi all, I've been enjoying using an AL-811 to help bust the pile-ups with my long wire antenna and Dentron Super Tuner Plus (manual tuner), but would really like to add a QRO autotuner to the mix.

Re: [Elecraft] Sub Band Speakers on 15M Band
Irwin, Do you have the Main tuned to 20 meters and the SubRX tuned to 15 meters? If so, the 20 meter Low Pass Filter is selected and will cut the 15 meter signal to almost nothing. The same thing can happen on other band combinations. To avoid that problem, either set the SubRX to a band lower than the MainRX. Or, use the AUX antenna input for the SubRX (that avoids the LPF). 73, Don W3FPR On 11/6/2014 11:29 AM, KD3TB wrote: With the K3 in Split mode and Sub turned on, on 20 Meters I can hear the Main and sub band in separate headset speakers, but cannot on 15 Meters Is there a Config/Menu function that has to be set by band? __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K2 receiver sensitivity on 12 and 10 Meters
Matt and all, While that is good info, be aware that the referenced application note which suggests reducing the value of Control Board R1 is applicable only to K2s below SN 3000. There is a pot at R1 for the AGC Threshold level on all K2s SN 3000 and above. You can adjust the AGC Threshold lower than the suggested 3.8 volts, but as you lower it, the values for CAL S LO and CAL S HI become more and more erratic. I suggest keeping the voltage at CB U2 pin 5 to 6.5 volts or higher - a minimum of 2.7 volts is normally sufficient. 73, Don W3FPR On 11/6/2014 12:31 PM, Matt VK2RQ wrote: There is an application note on the Elecraft website dealing with increasing the K2 sensitivity, although as the article mentions, there are trade offs: http://www.elecraft.com/Apps/RX_Gain_application_note.htm 73, Matt VK2RQ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Sub Band Speakers on 15M Band
Hi Irwin, The answer to your question is no but I think you're on the right track. There are several items that are band selectable that could affect the audio output of your SUB RX on 15 meters. The most likely of these is your antenna selection. If you accidentally selected ANT 2 or AUX RX for your SUB RX on 15 meters and if you don't have anything connected to those inputs then you would indeed hear no audio on your right channel speaker when on 15 meters. 73, Mike K2MK KD3TB wrote > With the K3 in Split mode and Sub turned on, on 20 Meters I can hear the > Main and sub band in separate headset speakers, but cannot on 15 Meters > > Is there a Config/Menu function that has to be set by band? > > Thanks, > > Irwin - KD3TB > > > > __ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto: > Elecraft@.qth > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to > lists+1215531472858-365791@.nabble -- View this message in context: http://elecraft.365791.n2.nabble.com/Sub-Band-Speakers-on-15M-Band-tp7594437p7594442.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Most likely the name of the port is /dev/ttyUSB0 as that has been standard convention for some time. Case matters in file names. If you are typing the name correctly, then all I can think of is that your username may not be a member of the 'dialout' group. You can easily check this in a terminal by typing the 'groups' command. There are various ways to do add your username to the 'dialout' group, as I recall, both Mint and Ubunutu offer a graphical program to manage your user's group membership. > When i unplug the KXUSB from the USB port on either Linux box and plug > it into my Mac, all is well.

I don't know about OS/X, but I recall that Windows will automatically make the device available to a non-privileged user. The Linux distributions are a bit more careful about security in this regard which sometimes seems like a bit of undue paranoia. 73, Nate -- "The optimist proclaims that we live in the best of all possible worlds.

Re: [Elecraft] K2 receiver sensitivity on 12 and 10 Meters
Here are some other ideas: I wonder if switching off the AGC makes much difference? If so, maybe it is kicking in too early, and you may need to look at setting the threshold (I think there are procedures in the K2 manual for this). You said peaking the band pass filter didn't help much (I guess you did this in the right order, as described in the manual?) What about the IF filter L34 adjustment? That could affect overall gain. Although not really related to sensitivity, while you are running alignment procedures, may as well go the whole way and check the setup of the crystal filter with spectrogram. It may be interesting to measure the sensitivity to see if there may be a problem. The following webpage may be a useful reference: http://www.cliftonlaboratories.com/k2_rx_sensitivity.htm When I built my K2, I used the measurement procedure in the XG3 signal generator manual to measure the sensitivity as a sanity check to see if I'd built it properly. The result came out somewhere in the ballpark of the figure published in Rob Sherwood's receiver performance list. http://www.sherweng.com/table.html There is an application note on the Elecraft website dealing with increasing the K2 sensitivity, although as the article mentions, there are trade offs: http://www.elecraft.com/Apps/RX_Gain_application_note.htm 73, Matt VK2RQ > On 7 Nov 2014, at 12:27 am, Hans J Rasmusen OZ7BQ wrote: > > Dear Don and Matt,Thank you for your comments.

Re: [Elecraft] [K3] Programmable/assignable Split Key?
Hi Jim, The SPLIT command can be sent using the macro FTx; or SWH13; FT1 turns SPLIT on FT0 turns SPLIT off SWH13 toggles SPLIT from off to on or from on to off If you do not have the DVR module in your K3 you can assign the M1 through M4 buttons (both tap and hold) as macro senders. In this way you are not limited to the PF1 and PF2 buttons. I use M2 through M4 to send SPLIT and SUB RX commands to the K3. And of course if you have a PC logging program running you should be able to set up macros from your PC keyboard. I have two macros that I use on my PC keyboard while running WriteLog that cause actions to occur on both my K3 and P3. One macro uses the F12 button and the other macro uses the * button on the numeric keypad. 73, Mike K2MK *** [Elecraft] [K3] Programmable/assignable Split Key? Jim Miller Wed, 05 Nov 2014 15:40:21 -0800 At one time there was mention of making the Split (Hold A>B) key assignable to a macro.

Re: [Elecraft] K2 receiver sensitivity on 12 and 10 Meters
Dear Don and Matt,Thank you for your comments. I know that being able to hear the antenna noise, should indicate that the sensitivity is OK.Measuring the noise level on the K2 speaker output indicate that the noise level incease 4 to 6 dB on 10 Meters, but barely on 12 M when the antenna is connected. The difference is just audible, and the general RX signal level is lower than on other bands.Peaking the filter does not improve the RX. TX produce full output on both bands. 73 OZ7BQ Hans Jørgen Den 0:44 torsdag den 6. november 2014 skrev Don Wilhelm : Hans, I would suggest you try re-peaking the K2 bandpass filters using Transmit.
