Wayne or Lyle - whichever one of you is awake after the flood of emails
you have been working through - Will the new K3 be able to TX on the Alaska emergency frequency of 5167.5 kHz? This is close to the 60 meter band, but not a "ham band" frequency. This channel is authorized to hams in or near Alaska for use during emergencies, and contacts between hams and non-hams (for example, the police or a commercial HF user) are authorized when the situation calls for it. The authorization is for SSB (USB) only, 150 watts max output. Also, this was touched on, but I would like a bit of clarification - One of my favorite ways to operate CW during a contest or DX pileup is to use both the main receiver and the sub-receiver in my Yaesu Mark 5 set to the same frequency but with different filter bandwidths, for example 400 Hz on the main and 500 Hz on the sub, which gives a quasi-stereo effect to the sound. When using a stereo headset, the different bandwidths make the signals seem to have a spatial differentiation that really helps sort out the pile. The only fly in the ointment is that on the Mark 5, you have to hold down a front-panel button to get the VFOs to track, which creates sort of a pain where I sit. Having the ability to have the 2 VFOs track automatically would be a big help. Otherwise, congratulations. My K2 works just FB, but the panel is a bit small. Maybe I can think about replacing one or even both of my Mark 5s. Anyone out there want to buy a fully loaded Mark 5? <grin> regards - - Jim, KL7CC _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

With the KBPF3 I should think it would be no problem, technically. > Also, this was touched on, but I would like a bit of clarification - One > of my favorite ways to operate CW during a contest or DX pileup is to > use both the main receiver and the sub-receiver in my Yaesu Mark 5 set > to the same frequency but with different filter bandwidths, for example > 400 Hz on the main and 500 Hz on the sub, which gives a quasi-stereo > effect to the sound.

Another feature the K3 possesses is "dual passband" or perhaps "context filtering." This lets you set a wider bandwidth at some dB down *and* a narrower bandwidth filter at the same time. So you could, for example, dial in a 1 kHz wide filter and set it 10 or 20 dB down and a narrow 200 Hz filter centered on your preferred pitch. You can thus hear the signal you want with emphasis, while still retaining some context of the activity nearby. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Toby;
The phase noise of the K3 is significantly less than the K2. One of our main design goals was to improve the local oscillator design of the K3 without adding significant cost to the radio. After much design work and experimental tests, we were able to find a unique design that did this. The TCXO option has no effect on phase noise, only on the long term frequency stability of the radio. -John KI6WX > > YAQ: What are the phase noise figures like?

Dear OMs/YLs:
I thought you might be interested in my spatial CW reception project. See: http://www.metaphoria.us/hamradio/ham_radio.htm It's the second link down.

Congratulations to all concerned for adding the K3 to the Elecraft stable.
Now I know what Wayne has been up to at 4 am! Looking forward to seeing the "numbers". 73, Geoff GM4ESD John, KI6WX wrote: > The phase noise of the K3 is significantly less than the K2.

Bob,
If it is working with the new power supply and antenna, why do you need further comments? - *Congratulations* on your success. The original antenna may have been out of range of the tuner's capability - you didn't specify the before and after antenna parameters or situation, so all I can do is guess about it. 73, Don W3FPR Bob P wrote: > > I have a problem I think I solved, but would like a few comments. > > I installed a new K1 2 Band Board and all things went smooth till I > tried to send with ATU > > First it would send on 40 meters, then at 80 I got a short chirp and a > low buzz intread of 800 Hz sound > > So I found a bigger power supply ( 2a vs my old .400 millia) and also > changed the antenna and all things are find. > > Life is Short, Learn Morse Code and have fun. > > Bob in Ohio, KC8IPQ > > _______________________________________________ > Elecraft mailing list > Post to: [hidden email] > You must be a subscriber to post to the list. > Subscriber Info (Addr.

Thom,
I'm sorry I missed this one. We've been overwhelmed by email the past few days. Lyle and I have been tag-teaming, covering most of the bases, we hope! > On another list, some users who have both Drake equipment and K2's > have been discussing the relative merits of the Drake NoiseBlankers > versus the K2 NB. The K3 noise blanker is a completely new design. It is being tested on a wide variety of noise sources. While it's impossible to say exactly how it would compare to other blankers on every noise type, I can assure you it's a significant enhancement. We studied several different design approaches before starting the KNB3, including the Drake circuit. In addition, the K3 includes DSP-based both noise blanking and noise reduction features that can mitigate noise problems I.F. blankers can't touch, no matter how sophisticated. > > There have also been discussions relative to passband tuning. The K3 includes passband tuning. It's designed to take maximum advantage of its large number of crystal roofing filters and I.F. DSP, in combination. There are two sets of controls: SHIFT/WIDTH, and HICUT/LOCUT. Tapping a single button switches between the two. An optimized DSP graphic on the LCD sits just above the knobs, and shows you at a glance whether the passband has been shifted or narrowed as a result of using these controls. The most appropriate roofing filter is selected automatically as these controls are rotated. If you have one of our [pending] variable-passband crystal roofing filters installed, then the 1st I.F. bandwidth (crystal filter) will closely track the 2nd I.F. bandwidth (DSP). This is far superior to receivers that have only wide roofing filters and try to do the whole job at the DSP, as well as receivers that simply shift one filter against another at two different IFs. Feel free to email me directly with further questions on this topic. 73, Wayne N6KR --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Thom,
I've mentioned the future variable passband filters several times, including in the very first posting. Not sure when they'll be available. Probably sometime after first shipments. In any case, you're right -- if you like this idea, then reserve at least one crystal filter slot for it. 73, Wayne N6KR On May 1, 2007, at 8:59 AM, W2AGN wrote: > wayne burdick wrote: > > >> The most appropriate roofing filter is selected automatically as >> these controls are rotated.

Up to three of the filters can be variable-bandwidth. These filters
have an additional 4-pin connector for bandwidth control. We have plans for at least two different types. 73, Wayne N6KR On May 1, 2007, at 9:59 AM, Toby Deinhardt wrote: > Yep - but only two of the five per RX can be variable if I have > understood correctly. --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
