Re: [Elecraft] K3 Configuration Question
I use the K3 Freq. Memory Editor sw to program up to 99 memories with specific freq./modes for quick switching. This is loaded via the RS232 port into the K3. Then all I do to change bands/modes is to press MV and rotate VFO-A to select memories 00-99. I have them grouped for favorite freq. in each band and mode: e.g. 51=14.020/CW, 52=14.070/DATA, 53=14.205/USB, 54=14.292/USB, 55=14.345/USB, and 56=15.000/AM ...etc. There are enough memories for me to add favorite 6m, 2m, and 1296 freq./mode memories. The last two bands require that the KV3A is set up using the XVn configuration settings (but that is another subject). 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-800*w, 432-100w, 1296-testing*, 3400-winter?

[Elecraft] K3 Configuration Question
I have K3 #2808 that I purchased used about 6 months ago. This week, I added the KAT3 antenna tuner and the 400 and 250 Hz 8-pole filters. All I can say is WOW!!! Now for my questionIs there a way to make the frequency follow the mode per band (or has this been discussed already and I missed it)? For instance, if I was on 14.228 on USB and changed to CW where I was last at 14.005, is there a way to make it follow the mode for that band? Then if I went to data where I was at 14.080, can it go to that point? Just curious if I missed something in the manual. Have a great Thanksgiving weekend everyone. I love my K3.

Re: [Elecraft] K3 Configuration Question
Larry, As far as I know there is no way to do it the way you asked, but there IS another way - by using the memories. If you use the Quick Memories, you can go to the last used frequency on any band - I set up my button 1 for 160 meters, 2 for 80, 3 for 40m, 4 for 20 m, 5 for 15 m, 6 for 10 m - then 7 thru 9 cover the WARC bands 30. 17, and 12 meters - lastly the 0 button covers 6 meters. You can define any button to any band, there is no reason to use the same selections that I have. Now the point is that once defined each button (press MV than the number button) can take you to any band - and it will remember the last used frequency (and mode) for both VFO A and VFO B. Now let's go one step further and also use the M1 through M4 buttons - I have M1 set for a frequency in the CW section of the band, M2 for the common DATA mode frequency, M3 for SSB, and M4 can be yet another frequency of your choosing. Once you are on any one band, these memory buttons can be used to skip from one place and mode quickly to another. Yes, there are also 90 more memories that can be used as well. And you can use macros to recall the memories if you want to get more exotic than just the normal K3 buttons - in fact you can also do the frequency, mode, (and most any other changes) through the use of macros - see the K3 Utility help file for examples. There are many ways to accomplish your end goal, just pick the one(s) that appeal to you the most and use them - even though it may not work like my last radio, the K3 provides the capability, it is just a matter of getting used to doing it the way the K3 accomplishes that goal. The K3 user interface has been scrubbed first by a focus group mainly of contesters and DXers, and has been further changed by the votes of the Firmware Field Test group, and even further refined by comments of other users offered on the reflector. So the capability is in the K3, and if you want to lobby (pleasantly) for your particular thought on how it should work, you are certainly invited to post to the reflector and see if you can find support for your idea - if there is enough, Wayne, Lyle and Eric are likely to make some changes if that is possible. 73, Don W3FPR On 11/26/2010 12:16 PM, Larry Boekeloo wrote: I have K3 #2808 that I purchased used about 6 months ago.

Re: [Elecraft] K3 Configuration Question
Larry, I think you can accomplish what you want by using the per-band quick memories as described on page 16 of the Owner's manual. Memories M 1 – M 4 are per-band quick memories. For example, you might set up M 1 for each band’s CW segment, M 2 for the SSB segment, etc. As an example, I have mine set so that M1 is CW, M2 SSB, M3 PSK and M4 RTTY.

[Elecraft] K3 configuration question
I would really appreciate help on getting the HRD DM780 interfaced with my K3. I have a EMU 0202 sound card and decoding CW from the radio is fine. I would like to get some help in getting the DM780 to send CW via the K3. I am sure I have missed something real basic. - Dan AB3EN -- View this message in context: http://n2.nabble.com/K3-configuration-question-tp3353305p3353305.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
[Elecraft] K3 configuration question
Hello elecrafters, i ordered a K3 with the additional KBPF3 module for general Coverage. Do i need the additional AM Filter for listening to AM radiostations? or ist this AM Filter only neccessary for AM TX? Thanks for your configuration support.

Re: [Elecraft] K3 configuration question
You need it if you want to listen to an AM stations full bandwidth. You'll not hear the entire transmitted signal without it. You'll be able to hear talk stations or something like that just fine but for listening to music you'd probably find it lacking. Hopefully this helps you in making your decision.

Re: [Elecraft] K3 configuration question
I had the same thought when ordering my K3, but I chose the FM filter instead of the AM filter. That will give me sufficient bandwidth for good quality AM RX as well as FM TX/RX. It's more likely that I'll use FM TX on 10m or 6m than AM anywhere. 73 -- Joe KB8AP On Sep 20, 2008, at 2:38 AM, Brett Howard wrote: You need it if you want to listen to an AM stations full bandwidth.

Fortunately, if you're not using FM transmit, it is possible to lie to the firmware and tell it FL1 is 6 KHz. While you can do this, I suggest you not do so. Here's why. The K3 uses a DSP IF at 15 kHz. The roofing filter is the primary means of suppressing the 15 kHz image on transmit and receive. In wideband modes (ESSB, AM and FM), this is especially true. The wider bandwidth of the 13 kHz FM filter results in poorer suppression of the image. In the FM sub-bands, it is suppressed well within the definition of good engineering practice. Further, FM is not considered to be a weak-signal mode. SSB is often a weak signal mode, and ESSB and AM operations are typically within the image offset of potential weak signal operations. Thus, if you transmit in other than an FM sub-band using the FM filter, you risk interfering with nearby weak signal operation. We are studying the use of the FM filter for such purposes, but we have not yet completed our characterization of the use of the FM filter for non-FM use. When we do, and if the image suppression is sufficient to allow you to be a good neighbor when running your K3 to drive a legal limit amplifier such that the transmit image is in a nearby weak-signal area, we'll directly support its use in the K3 firmware. Until then, please consider the potential interference you may cause if you use the FM filter in this manner. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 configuration question
The K3 uses a DSP IF at 15 kHz. The roofing filter is the primary means of suppressing the 15 kHz image on transmit and receive. In wideband modes (ESSB, AM and FM), this is especially true. Let's see ... with a 15 KHz DSP IF, the image would be 30 KHz minus the modulating frequency (for AM) from the center of the transmit (roofing) filter. Based on the specifications of Inrad's 8 and 9 MHz AM filters (8 pole) and their 7 MHz (6 pole) front end filters (15 and 20 KHz wide at -1 dB), the FM filter's shape factor should be in the 1.6 to 1.8 range and the -60 dB bandwidth between 20 and 25 KHz. Unless the filter or circuit layout has a major problem, the response should down at least 90 dB at +/- 15 KHz. With AM (worst case), assuming the carrier is centered in the filter and a highest modulating frequency of 4 KHz (K3 limit for ESSB), the image sideband is 26 KHz from the center of the (transmit) IF filter - well into the filter stopband. With an ultimate rejection of only 90 dB 25 KHz away from the center of the filter, the transmitted image from a 1500 Watt (peak) amplifier will be 1.5 microwatts peak for an ESSB signal, 0.75 microwatts for the carrier of an AM signal or 0.375 microwatts for the sideband of an AM signal. 90 dB of image rejection is more than 30 dB better than the 5th order IMD from most amateur 1500 watt amplifiers and 40 dB better than the K3's own 9th order IMD performance (ARRL measurements). 73, ...
