Re: [Elecraft] Problems with knobs
My K3 is serial #5102 purchased in January 2011. My VFO B knob has just cracked: it's spontaneously developed ugly linear fissures across the face of the knob. The cracks begin nowhere near the screw hole. There are two cracks. The rig has spent its life in an internal room with no UV exposure. I emailed Elecraft and the response was perfect, as usual: a replacement knob was in the mail less than a day after I'd made email contact with the parts department. This is the first/only report of a cracked VFO knob. Such things happen - that's the nature of matter and entropy. What's important to me is the great response from Elecraft. That's why I buy from them. Thanks Richard & Co.

Re: [Elecraft] P3 - Power up glitches with K3
Hi Phil, It does take several seconds for the K3 to initialize the P3 at power up but if some parameters are not getting initialized it must be a hardware problem with the serial interface. It sounds like you have already confirmed that the locking screws on both ends of the serial cable are tight. If you have a spare cable you might try that. Another possibility is a bad KIO3 board in the K3. Some units have a marginal negative power supply that can affect signal integrity. If you can borrow another K3, you could temporarily substitute it to tell if the problem is with the K3 or P3. I would contact Elecraft support to see what they recommend. k3supp...@elecraft.com Alan N1AL On Fri, 2011-12-23 at 17:40 -0800, Phil Westover wrote: > I've got a P3 connected to my K3 with all the proper connections. > > K3 info: > s/n 1206 > Firmware: MCU 4.36, DSP 2.73, Flash Parameters 1.14 > P3 info: > s/n 1490 > Firmware: 1.09 > > When I first hooked up the P3 a few months ago, I set the jumpers (and > connected a power cable) to power it up from the K3.

[Elecraft] P3 - Power up glitches with K3
I've got a P3 connected to my K3 with all the proper connections.

At that time, I got immediate connection and immediate "talking" between the P3 and the K3. Frequency and filter width showed up correctly immediately at power up. After a couple of months, it appears to not immediately 'talk' with the K3 upon power up. Sometimes no frequency nor filter bandwidth are displayed. Sometimes frequency is displayed, but no filter bandwidth. Sometimes the bandwidth shows up and is shifted off the right. In all cases, I can manually power down the P3 and toggle it back up, and all those things eventually show up properly. Sometimes it takes several on-off toggles (5 or more). In one instance, it didn't come up after several toggles, then about 10 minutes later they started talking correctly. Cables are tightly attached. There is no movement to the rigs during use.

[Elecraft] KPA500 Running Hot?
When I operated the OL-OK RTTY DX contest, I ran the KPA at 300 Watts output. The fan would generally go up three steps when I was running 'em, and the temperature got into the 60's. The fan was a little loud, but tolerable with earphones on. But today, I had occasion to need the amp to complete a QSO with a DX station on 20. I ran 150 Watts output and my transmissions were no more than 3 minutes long. Yet, every time I was transmitting a minute or so, the fan would kick in, and it stepped up three or four times by the time I was finsished. Now THAT was loud! Plus, the top rear of the amp was quite warm. Exhaust from the fan was warm, too! I didn't have the presence of mind to check the temperature today. Any ideas? Has anybody else had this experience?

[Elecraft] K3 MCU 4.47 Merry Christmas to me!
So I go to have a holiday lunch with a bunch of hams, and I sit across from fellow K3'r Paul, NF8J. We are a talking away, and I mention something about my remote base, and Paul tells me (I've been off this reflector for a while), that the K3 can now work with the RemoteRig. I was a little puzzled, as I use the RemoteRig with my K3, driving the home unit with my home computer and a copy of TRX. Nope Paul sez, there was something on the reflector. So I come home, and read up on firmware 4.47. Well, let's update both K3's, the one at home and the one at the remote base. Update the RemoteRig firmware at both ends, and then make up a simple rs-232 null-modem cable. Well, look at this. No mouse mouse dragging. Turn this knob, and the remote site K3 totally obeys. *This Is Way Cool!* Wayne, Eric et al, thank you for the Christmas Present. Now, the only problem is with K8AJ wanting to use it. Hmmm. 73 to all, de tom bosscher K8TB p.s., Eric and Wayne, I would LOVE to be able to buy just a front panel with a simple rs-232 interface, so I can use the remote base while K8AJ uses the local K3. Or the other way around if she wants to. :) __ 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
Re: [Elecraft] K3 + LP100A + Dummy Load
Just a comment on dummy loads: I do a lot of ham radio work at VHF and higher (up to 10-GHz), so making good power measurements involves having a good 50-ohm termination (load). For most of my testing I have several coaxial loads: A 25w Termaline (Bird) is used a lot in the shack as it tests Z=51 + j0 on my MFJ-269B antenna analyzer and shows zero reflected on a Bird43 power meter. Some of the other loads show 52 or even 54 ohms on the MFJ, and not quite resistive (I marked all them so I would know). In all cases resistance measurement with an ohmmeter agrees with the R parameter in the complex impedance equation. I even have a 500w Sierra termination (door stop load) which has a integral power meter, but it is not exactly 50-ohms and the meter is not in agreement with the Bird43, so I use it as a safe load for high power but not for high accuracy measurements. I have seen coax loads shift way off 50-ohms due to overheating from too much or too long a transmission. I bought some of the Cadsoft 100w surface-mount attenuators to use in a 900-MHz amplifier to permit driving with 10w exciter. They were in the $12 range from Mouser. One can make very fine 50-ohm loads using them on a proper heat sink at a fraction of the cost of coaxial loads. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?

Re: [Elecraft] Impact of this mod: K3 I.F. Output Buffer GainModification???
The P3 is usable without the mod but it increases the sensitivity of the P3 display. On the low bands you probably won't notice any difference but if you do much 10 or 6 meter operating you probably want to make sure the modification has been done. I'm not sure of the serial number of the changeover, but the web site says "RF board Rev H3 and later" have the new resistor value.

Re: [Elecraft] Impact of this mod: K3 I.F. Output Buffer GainModification???
The app note says that the mod is incorporated into all new K3's since September 2009. Without it, the P3 (or other panadapters) should still function, but some weak signals may be undetectable due to the noise floor of the IF being below that of the panadapter. ~iain / N6ML On Fri, Dec 23, 2011 at 10:22 AM, Mike wrote: > I'd be interested in knowing also. > > 73, Mike NF4L > > On 12/23/2011 12:15 PM, Matt Zilmer wrote: >> The main value is bringing the IF output up to a level that is usable >> by the P3. >> >> I thought that the mod was in all K3's after s/n 3600-something or >> other, but there are probably experts around (or Elecraft crew) that >> know the exact cut-in s/n or date. >> >> 73, >> matt W6NIA >> >> On Fri, 23 Dec 2011 09:05:22 -0800 (PST), you wrote: >> >>> Can someone explain the real world value of making this modification?

Re: [Elecraft] K3 Mic input rear panel
Hello Pete, The rear panel mic jack is a stereo (T-R-S) jack with the mono mic signal on the tip. The ring is not connected. It is an unbalanced input and accepts balanced or unbalanced dynamic mics but only unbalanced electret condenser mics. When RL.X bias is on, it supplies 8 volts. You can glean most of this by perusing the schematics. You can also see a summary of all the KIO3 connections in the chapter 7 sampler for the KE7X K3 book. Have a look at www.ke7x.com.

Re: [Elecraft] KAT2 only intermittently recognized by the K2

Re: [Elecraft] Problems with knobs
What happened with the old knobs is that the material was not fully cured, and they would shrink. So slowly it was like severely over-tightening the knobs.

Re: [Elecraft] K2 - Fuses ...A Cautionary Tale
I took a Sharpie that had laying on my workbench, and "changed the color" of the aux power connector both on the board and the wiring harness, which is what the manual suggests, IIRC. No, it doesn't prevent one from swapping them, but is a visual indication which one goes where. One still has to take their time when working on a $1000 piece of equipment.

Just one other caution, if I may. Before dabbling inside any piece of equipment where a current can possibly flow, remove any rings from your fingers and remove your wristwatch and any other conductive material. If they happen to be on the hand in your pocket, so be it, but don't forget that if something happens, you may react without thinking and put that left hand into service.

Re: [Elecraft] No 6m on KPA500
Sounds like the KPA500 Pin11 inhibit input is low on 6-meters. If you are using the Elecraft 6-meter preamp and switching it on automatically using this pin on the K3 accessory port, then you are also disabling the amplifier on that band. Pin11 needs to stay high.

Re: [Elecraft] Reference Oscillator Calibration
Hi Don, I'm awaiting the arrival of the G5RV from True Talk. It has a lot of good reviews over at eham. I'm not sure where I'll put it, though. I was thinking of the attic, but 50 ft is longer than my 25 ft attic. I'm also considering one of the tak-tenna (taktenna.com) setups. This is another with good eham reviews and looks relatively simple to set up on the roof of the house. I know the antenna is as important as the transceiver, and I'm hoping for a more elaborate setup eventually, but right now I'd be happy with a basic operational level. I'm trying to figure out how to set up the grounding. Also, the wiring in the house wasn't done by professionals. The receptacle tester shows a number of outlets having a ground/neutral reversed error. Some check out ok and others don't even have the ground connection on the receptacle. Hopefully I won't have to rewire the whole house. As always, any suggestions are welcome. Merry Christmas to you, too!
