[Elecraft] Win4K3Suite mic interface question
I just purchased Win4K3Suite for my KX3. I would like to setup the spectrum scope, but until I can get my main pc out of storage as we wait for our new house to be completed, I am stuck with a Lenovo Thinkpad that has a combination headphone microphone plug jack. I understand that I need a separate stereo usb sound interface that I can connect my RX/IQ port on the KX3 to the laptop computer's mic input. I would appreciate any suggestions that would help me get the correct usb interface.

Re: [Elecraft] P3 SVGA interference -
Does the RFI go away if you remove the antenna connection to your radio?

[Elecraft] P3: Feature request
Hi there Elecraft programmers, Feature request here... Would it be possible to add a user controllable switch in the P3 setup for the Transmit monitor, which allows the numeric SWR and POWER reading to be held, as opposed to being removed at termination of transmit?

[Elecraft] Elecraft CW Net Announcement
Good Evening, “What’s that?!”, my visual cortex rapidly scanned its card catalog seeking a best fit solution. Another part of my brain was trying to decide flight or fight while further processing power was devoted to wondering why there was a bush where none had been before. Then the bush’s tail flicked and a black tailed deer resolved the confusion. In her winter coloration she was popping in and out of focus with the background. Since I had made no sound she kept munching the leaves of the low lying bramble. Brambles are a nasty vine covered with fine spines which always trip me if I am not walking like there is a foot of snow on the ground. If you aren’t wearing leather gloves those spines sink into your skin and irritate for a week. She was efficiently nipping the leaves off from along its length without noticing them. I would not have put my snout nearly as close to the spiny stem. She ate only a few feet from me for about fifteen minutes while I sat at my computer reading the morning news. The sun is active. There are a few rapidly growing spots and the solar flux has risen to 78. There may be propagation available for us to use. Woo hoo! It has been a while. Now to test this hypothesis. Please join us tomorrow on: 14050 kHz at 2300z Sunday (3 PM PST Sunday) 7045 kHz at 0100z Monday (5 PM PST Sunday) 73, Kevin.

Re: [Elecraft] KPA1500 ATU - ability to handle more than two antennas
Wayne, Thanks for the response. I waited to respond until the KPA1500 manual was published to see if there were any PF1/PF2 functions out of the box. What I'd like to see first is much less fancy than interacting with external relay-based antenna switching like you mentioned. How about initially providing a second set of ATU segment memories to allow a /manual/ external switch? The amp can't know or control which antenna is selected but it would be very handy to have a PF function key the operator could use to toggle between ATU segment set one and two, for example, when the manual antenna switch position is changed. I envision it like this: ANT1 \ Manual Switch \--: Antenna 1 (Manually select ATU logical segment set 1 with PF1 tap) \--: Antenna 2 (Manually select ATU logical segment set 2 with PF1 hold) ANT2 \ Manual Switch \--: Antenna 3 (Manually select ATU logical segment set 1 with PF1 tap) \--: Antenna 4 (Manually select ATU logical segment set 2 with PF1 hold) Just a manual logical segment set change in support of manual external antenna switching. Is that do-able? I imagine I'm not alone in the use of manual antenna switches and needing to accommodate more than two antennas without the ATU experiencing a high-SWR-triggered re-tune hunt each time an external switch selects a different antenna.

Re: [Elecraft] P3 SVGA interference -
Mike, You didn't mention if you had a large monitor connected but consider that the noise you "see" may come from it or a TV your have connected. Do you see the pattern on the P3 also? Watch the P3 screen and turn the large monitor off and see if the signal disappears. Many of them do make a lot of electrical "noise" - particularly the screen light source and very particularly plasma displays.

Thus your numbers of 200 Hz to 2900 Hz is 2.7 kHz, otherwise about the 6 dB points on the filter. I did not go into the ESSB mode and perform any measurements. These were done in DATA mode, thus negating TX EQ and Speech Processing. I also did similar measurement with TX ALC OFF and in USB mode and in USB with TX EQ set to 0 dB at all frequencies and well below any ALC action. While I'm always reluctant to measure and report transmit frequency response of a SSB transmit path, namely because many users not understanding what takes place, thus would exclaim "that's horrible frequency response" while in fact just the opposite is true in that it makes for darn good sounding audio. To answer your question, referring to the Elecraft manual and the Fred Cady book, I find no way to "adjust" the transmit frequency response other than via the TX EQ.

[Elecraft] LCD "+" Icon on in CW Mode
The "+" icon is on in the Mode portion of the LCD window in CW mode on one of my K3s. It is off in SSB mode. What does that mean and how do I turn it off? Page 36 of the manual indicates it is only on when ESSB is selected. 73, Ken, K6LA / VY2TT __ 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] K3s transmit bandwidth adjustment?
Based on my measurements the transmit frequency response is limited by the 2.7 kHz SSB filter. It is reasonably flat thus +/-3 dB from 400 Hz to about 2500 Hz. My next measurement points were 300 Hz {-6 dB} on the low end and 3000 Hz {-6 dB} on the high end or 2700 Hz. Thus your numbers of 200 Hz to 2900 Hz is 2.7 kHz, otherwise about the 6 dB points on the filter. I did not go into the ESSB mode and perform any measurements. These were done in DATA mode, thus negating TX EQ and Speech Processing. I also did similar measurement with TX ALC OFF and in USB mode and in USB with TX EQ set to 0 dB at all frequencies and well below any ALC action. While I'm always reluctant to measure and report transmit frequency response of a SSB transmit path, namely because many users not understanding what takes place, thus would exclaim "that's horrible frequency response" while in fact just the opposite is true in that it makes for darn good sounding audio. To answer your question, referring to the Elecraft manual and the Fred Cady book, I find no way to "adjust" the transmit frequency response other than via the TX EQ. On that point, I will emphatically state "it is always better to attenuate a frequency or range of frequencies as opposed to boost a frequency or range of frequencies". 73 Bob, K4TAX On 2/10/2018 12:04 PM, Michael Blake wrote: Using normal SSB with the stock 2.7kHz. wide crystal filter is there any way to adjust the lower and upper bandwidth frequency ranges other than the TX EQ?

[Elecraft] K3s transmit bandwidth adjustment?
Using normal SSB with the stock 2.7kHz. wide crystal filter is there any way to adjust the lower and upper bandwidth frequency ranges other than the TX EQ? For example how would I adjust so that my 2.7 kHz. bandwidth was from 200Hz. to 2900Hz.?

[Elecraft] KX2 firmware suggestion
While in CW mode, I typically listen with the filter wide open (2.8khz). Once I find a signal, I narrow the filter down (400hz) by tapping the AF knob after tapping the FIL button. Opening up the filter (back to search mode) requires lots of cranking on the AF knob (back to 2.8khz) after tapping the FIL button. Wouldn’t it be nice if tapping the AF knob while in filter adjust mode would return the filter bandwidth to it’s previous setting (toggle between wide and narrow). Maybe there’s a way to quickly switch the filter BW back and forth (wide-narrow-wide) without having to crank the AF knob that I’m not aware? If not, seems like it would be an easy firmware update. __ 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] New KAT500/KPA500 setup and utility software problems
IMHO Norton is one of the most insidious viruses of all time. Ditch it completely and run one of the free Microsoft offerings and possibly Malwarebytes. You will need to run the KPA500 Utility to update its firmware, change the start-up banner and set various menu items easily. You should read the KAT500 manual along with Fred Cady's book. They give you sensible frequency segments to 'train' the KAT500, which is done in Auto mode. Once you've stored tuning parameters (automatic) for each band and antenna, you should switch to Manual mode, then every time you use a particular frequency, the KAT500 will tune to the nearest segment and settle down within milliseconds. 73, Alan.

Issues I am having: 1) KAT500 makes quite a racket whenever keying up. It seems to settle down, but as soon as I speak, it freaks out again. He has two antennas...a hex beam on ant 1 and a G5RV on ant 2. The KAT500 seems to behave the same on both. 2) He is running Norton on his PC. Norton allowed me to download the KAT500 utility, but not the KPA500 utility. It automatically deletes it. What's up with that? Thanks for any assistance. I tried to contact Elecraft support, but I guess I was too close to closing.
