Some DX operators (the ones I like) go through a pileup in one direction, moving up or down a discrete amount each time. Then they either 'snap back' to the other end of the pileup, or tune back the way they came. This is the best case, because if you are thinking you can predict where to call accurately -- and only a small percentage of callers are thinking! Others hop around between two general areas. You can imagine them flipping back and forth each time. If you detect this, it can be helpful. Some operators pretty much listen in one spot, plus or minus a few hundred Hz. for a long time. Pretty soon everyone learns where this is! Sometimes a guy will just randomly pick someone to answer with no discernible pattern. This can be frustrating. You really do need two receivers to spot the pattern. It can be hard when the DX is working stations that you can't hear.

Frank - W6NEK - Original Message - From: The Smiths To: elecraft@mailman.qth.net Sent: Tuesday, February 03, 2009 8:54 PM Subject: [Elecraft] ECO for SPOT Control I would like to suggest an upgrade for the SPOT control function. As you know, the SPOT function changes the Main VFO's frequency to Beat Frequency a CW signal. This function is wonderful when used to tune in a received signal within the CWT area. However, if after sending a CQ, and having someone answer you, you hit the SPOT control, you once again move your Main VFO off frequency. This risks the other party answering your CQ from being able to find you once again. My suggestion would be to allow for the SPOT button to function as a RIT only control when the RIT button is engaged. If the RIT button is NOT engaged, then the Main VFO would move as normal. OR if the XIT button is engaged, then the SPOT function would also work as it does currently. Having the SPOT work as a RIT control when the RIT button is engaged, would make it MUCH easier for a user (contester etc..) to send a CQ, wait for an answer, then align the K3 to the answering parties BFO frequency, without moving the Main VFO frequency. Thus, Making the RIT knob a secondary tool for finding people too off center to capture in the CWT area. I would love to see some feedback on this new feature, and ask that it gets implemented in the software if enough people agree with me. If you don't understand, or need further explanation please let me know.

Fortunately, I was able to replace the Power Pole plastic shells without disassembling the K3. It required: 1) removing both the positive and negative shells using a small tool to lift the metal connector blades inside, 2) mating a new pair of connector, 3) scraping off a small protusion on the positive connector to allow the assembly to fit in the rear panel opening, and 4) sliding the assembly over the connector blades. Perhaps this will help if someone else encounters this problem. Chuck, AE4CW Chuck and others, I have found that when you want larger cabling like #8 and above, the auto supply store is the best place to get flexible cables.

I use a MFJ tuner between my Rig and Amp because the Old Bard told me to. Actually my setup is different than what I just described, but I'm simplifying this for the question at hand. [ What I really do is K3 - Small MFJ Tuner - SB200 - Big MFJ Tuner - Dipole ] I don't know why the Old Bard told you to do that. It makes no sense to me. First of all take the small MFJ tuner out of the line and connect the K3 directly to the SB200. The tuner in the K3 will do the job of the small MFJ tuner. No sense adding tuner loss between the Amp and the rig. I suspect the Old Bard told you that because the input of the SB200 is not 50 ohms. More about that later... On the watt meter of the (small) MFJ Tuner, the indication is I have a non favorable SWR, more reflected power than had I put the KAT3 in bypass and manually tuned the MFJ Tuner to a favorable SWR (1.0 to 1.2 or so). This indicates that the SB200 input is not 50 ohms. You may have some troubles with the SB200 input, but you should be able to adjust that. Look at the SB200 manual and see if it has input matching adjustments. You certainly don't need two tuners for the SB200 input! So, can someone explain in basic terms what's happening when I use Auto mode on the KAT3 and see favorable SWR on the KAT3 (via K3 display) but do not see favorable SWR on the MFJ tuner? Here's what is going on. In the configuration you have now, you are correcting the mismatch between the small tuner and the K3. When you remove the small tuner you will be seeing the input of the large tuner (If you have the amp turned off or in standby.) When you use a tuner on an antenna, you don't change the antenna, you change what the rig sees at the feed end of the coax. I have an amplifier and large tuner. Here is what I do when using an antenna that doesn't have a good match. 1. Put the K3 in tune (hold the XMIT button). Adjust the large tuner connected to the output of the Amplifier for the lowest SWR. You want the amp turned off or in standby at this point. 2. Turn off the tune on the K3. 3. Make sure the power setting on the K3 is set below the normal drive power of the Amp. 4. Turn the amp on or take it out of standby. Hold the XMIT button in on the K3 and adjust the amplifier's tune and load according to the manual that came with it. Your K3 tune level should be about 15 or 20 watts or something below the full output drive of the amp. Turn off the K3 tune. 5. If, and only if you saw a high SWR on the K3 meter, tap the ATU Tune button and tune the K3 to the input of the amp. 6. Hold your CW key or what ever your using to send input power to the amp and adjust the amp tune and load for the output you want from it. Now you're good to go :o) 73, Tom, N5GE http://www.n5ge.com http://www.swotrc.net [snip] ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] OT Tuner Basics
On Thu, 15 Jan 2009 11:20:37 -0800 (PST), you wrote: I may have led this question astray.. I hope this wraps it. [snip] Yes, I do that too. In my station, I put the analyzer so that I can select a transmitter of K3, YaeKenCom, or Analyzer. This way the coax path is nearly identical between the analyzer down to ant. vs. the rig down to ant. Not identical but close enough that when the time comes to put the key down my match is pretty close and I trim it up on the big tuner (amp to antenna). Then when I select analyzer, I read the R/Z/SWR values off the analyzer as I do my darndest to match with the manual conventional tuner between the amp and antenna (big MFJ tuner). Then when I got it setup, I switch Tx back to K3, and use the AUTO tune function of the K3's ATu to polish up and away I go with nearly full PEP power that I can get. In all instances that I use the K3/ATU, the tuner between the K3 and Amp is in bypass. In all instances that I do not use the K3/ATU then the tuner between the other rig and the amp is NOT in bypass. In all instances the big-tuner between the Amp and Antenna is NOT in bypass. Now you're good to go :o) I think so, thanks! Great! If you tune the input coils in the amp as Jan suggests you may even be able to bypass the K3 tuner also.

[Elecraft] KRC2
Having never used a device like the KRC2 I'd like to ask a question about antenna relay boxes and coaxial relays. 1. Is the KRC2 compatable with the common relay switches sold by Ameritron, Etc.? 2. Is it possible to use it with coaxil relays for VHF and UHF antenna switching?

Re: [Elecraft] K3 1.0 KHz filter for CW - Needed?
On Mon, 12 Jan 2009 08:37:21 -0700, you wrote: I recently added this filter to my K3 to go with the 2.7 KHz and 500 Hz filters it already has. These are roofing filters so there is a question of whether or not they're needed - or even if they make a difference you can hear. I've spent time tuning the bands (mostly 40) with my filter width set to 1.1 KHz and 1.0 KHz, listening to the difference as the crystal filter is engaged. Is it needed? I'd usually no. Does it make a difference? Most definitely! I greatly prefer to operate with the 1.0 KHz filter engaged. I can keep my DSP bandwidth wider while still rejecting noise from 2 KHz away. The overall level of grunge in the receiver goes down when the crystal filter kicks in. I used to run with the DSP set to about 700 Hz to get the overall sound I wanted. With the crystal filter, I can open the DSP to 1000 Hz and get the same or more rejection of signals several KHz away. - Keith N1AS - - K3 711 - With the selectivity the K3 has the 1k filter opens up just enough to allow you not to miss weak stations while moving the vfo up and down the band. That's what I use it for. Tom, N5GE ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
