Re: [Elecraft] KAT500 tuning help
Hi, I have also noticed that manual tuning is not memorized withe the memorize button. I have generally obtained 1.3:1 or less using AUTO so I haven't played with it a lot. I do have some problems at the high end of 15m where the raw SWR is just over 12:1. AB2TC - Knut RobertG wrote I've got the K3, KPA500, and have just installed a factory-built KAT500. Some glitches/questions about tuning the KAT500. I have found that, using the utility program, I can manually tune to a much lower indicated SWR than the unit can in AUTO. Anyone else found this to be so? More importantly, when I do tune to a low SWR on a band, click on MEMORIZE, shift bands and come back, the values in the utility program don't return to what I just told the KAT to memorize. In other words, the system is not remembering my manual tuning values when I switch bands. Any comments/guidance much appreciated. ...robert -- Robert G.

Re: [Elecraft] auto tuners
To protect the rig the Ham must drop the power output to a safe level before initiating a KAT500 Tune operation, just as one would do to adjust a manual tuner. The difference is that the Ham doesn't have to manually turn knobs on the KAT500 to find the best match. The SWR the rig sees varies widely while the KAT500 is tuning. Some rigs even require manually retuning the transmitter or amplifier output before allowing the KAT500 to tune. The procedure for doing this safely is described on page 13 of the KAT500 manual. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of bill ny9h Sent: Sunday, December 16, 2012 7:36 AM To: elecraft@mailman.qth.net Subject: [Elecraft] auto tuners while we are fortunate to have a K3 which auto drops power for tuning what about rigs that tune at higher power or full power... what does the rig's output see at the input to the tuner when the tuner is clunking/clanking along relays switching C L components ??? 50 ohms...??

Re: [Elecraft] K144XV vs XV144
Not a comment on the K144XV vs XV144, but one about running eme. Use of a low-noise figure preamp is not optional for eme, so transverter sensitivity is less important an issue, though its nice if it is low. I use a DEMI 144-28 transverter with 0.8 dB NF (unmeasured) and 17-dB conversion gain. With my 0.1 dB NF preamp (26-dB gain) this produces a S4 noise floor in the K3 on 28-MHz (a bit too much gain). This will result in impacting large signal handling but I have no issues for that on 2m since the nearest active 2m eme station is in BC about 1300km away. Use of an external preamp is encouraged on 2m and higher freq if one is into working CW/SSB/digital long-range, weak-signal contacts. You can't work em if you can't hear me! My 2m-eme receiving system MDS= -153 dBm. (-172 dBm with antenna gain). K3 diversity receiving makes eme a real joy! Best Wished for the Holidays! Ed - KL7UW we will be attending Dayton this year!

Re: [Elecraft] auto tuners
That's right Chuck. But, as Bill observed, SWR swings while the KAT500 is tuning could endanger components in some non-Elecraft rigs driving it at that power. If a tender QRO amp that cannot handle a large mismatch at its output were to feed high power (100 watts) into the KAT500 it could suffer a failure since the KAT500 will refuse to switch to protect itself from damage. The amp will see whatever SWR is present. So it's important for someone operating a non-Elecraft amplifier, or barefoot rig for that matter, to know how to configure it for safe tuning, whether they are using a KAT500 or any other tuner. 73, Ron AC7AC -Original Message- Seems like I read it, the KAT500, was good up to 100 watts for tuning.

Re: [Elecraft] 12 meter band on K3
Don, Were you really tuned to 12 meters? or somewhere else? There is the possibility that you have a problem with your K2. I have not listened to 12 meters, but if I understand you correctly, you listened to 12 meters with the K2, the K3 and some other radio - and 2 out of 3 did not hear the signals. That causes me to wonder if you were really listening to 12 meters on the K2. One check you can make is to use the internal frequency counter probe and see what the frequency at TP1 (the VFO output) is when tuned to 12 meters - then add 4913 kHz and you should have to actual operating frequency. There is one more check to make to see if you are really hearing 12 meters - run the K3 (tuned to 12 meters) into a dummy load, then connect a short antenna to the K2, placing that antenna near the dummy load. You should be able to hear the K3 signal on the K2. 73, Don W3FPR On 12/16/2012 12:11 PM, haircut...@verizon.net wrote: This morning I was listening to different bands on my K2.

[Elecraft] K3 Filters (again???!!) - Many Thanks
Hi, Many thanks to all who responded to my query about which filters to purchase for WJST modes. The replies were varied and all were based on sound argument - ie what worked best for that particular operator. The consensus of opinion boiled down to just get the basic filter, see how you get on and if necessary get others as and when needed. What was interesting was that of all who expressed an opinion said go for the kit instead of buying it completed which makes a lot of sense both financially and to learn a little about how the rig worked. I tried to answer all who contacted me but my server refused to send on my reply to Jim KG0KP who I would like to thank via this medium.

[Elecraft] KPA500 Firmware Update and USB-Serial Cable ?
Gang, OK, I was going to update the firmware with the latest (1.18 I think) version for the KPA500 and realized that I did not have a PC USB to KPA500 Serial (DB9) cable for this. My first question: was one supposed to come with the KPA500? If so, I will need to look around better. If not, I am wondering how I missed ordering that. Second question: is the USB to Serial cable needed by the KPA500 the same as used with the K3.

Re: [Elecraft] Possible firmware regression related to ACC2 IO / PTT=LO
No intentional change was made to this, Mark. Please try activating the PTT=LO function of ACC2 manually, by shorting the signal to ground. If that works correctly, but it doesn't work from your 590's keyline, then I'd suspect the connection. 73, Wayne N6KR On Dec 14, 2012, at 9:05 PM, K7MJG wrote: Hello, In my setup, I use the KX3 as a receiver (only) and a TS-590s as a 100 watt transmitter.

This has worked well for me so far. When the 590 is keyed up, the KX3 goes into transmit (with the TX light illuminated) and the receiver is shut off. However, recently, (probably with the latest 1.30 firmware release), I see something strange and certainly dangerous to my KX3. When I key up the 590 (a quick dit with 5 watts - the minimum), the KX3 TX light goes on, but I can see what I am transmitting (CW) on my CW Skimmer screen! I can tune the 590 to other frequencies and CW skimmer follows the 590's TX frequency. This tells me that the KX3 is actually receiving what I'm transmitting with the 590 even though the TX light is on and the RX should be disabled. Note that the KX3's S-meter is not deflected (no apparent signal). Can someone (possibly one of the firmware engineers at Elecraft) tell me if a recent behavioral change was made to the ACC2 PTT controls?

Bob, To receive VLF you will need a VLF converter. The IF connection on the K3 is only an output, so the converter will connect to one of the antenna inputs to the K3. If it is to be receive only, you could connect to the RX antenna input or to the ANT1 or ANT2 connections of the KAT3, or to the RX port of the KXV3. If the external device is to transmit as well as receive, you can connect it to one of the KAT3 antenna jacks, or if it is capable of 1 mW IF transmit levels, connect it to the same IF connectors as used for the VHF/UHF transverters. 73, Don W3FPR On 12/16/2012 6:31 PM, KD7YZ Bob wrote: Howdy K3' people: Here's another one I am trying to solve.

Re: [Elecraft] K3 Filters (again???!!) - Many Thanks
Peter, The K3 filters are quite easy to install later - *unless* you have the KRX3 installed. If you are considering the subRX as part of your order, then I suggest you do not install the subRX until you have gotten a handle on the filters that you will want. Install those filters and then install the KRX3. The reason is entirely physical - the K3 main RX filters are beneath the KRX3, so that assembly must be removed to add additional filters to the main K3 RX. 73, Don W3FPR On 12/16/2012 4:41 PM, PETER HUTCHISON wrote: Hi, Many thanks to all who responded to my query about which filters to purchase for WJST modes.

Re: [Elecraft] KPA500 Firmware Update and USB-Serial Cable ?
For the short term, you can use the same cable you use for installing K3 firmware, just move it over to the KPA500. A standard serial cable, either USB to Serial or 9-pin to a real RS-232 port is required, just the same requirement as your K3. I don't believe one came with the KPA500 unless you specifically ordered it. We have been sending a USB to Serial Adapter with our devices that have 3.5mm connectors (KX3, XG3, KAT500), but the more generic K3 and KPA500 don't come with a cable. At least that's my recollection. I use a four-port Gearmo USB to Serial adapter that uses the FTDI chip set. I use one port (COM2) for my P3/K3, another (COM3) for a KPA500, another (COM4) with an Elecraft KXSER cable for a KAT500 and the last COM5 with another KXSER cable for the KX3 or XG3, I have to choose between these. I use COM1 for an LP-100A. http://www.amazon.com/FT4232HL-Professional-Retention-Certified-Microsoft/d p/B004ETDC8K/ref=sr_1_2?ie=UTF8qid=1355703302sr=8-2keywords=4-port+usb+to +serial+adapter The KXSER cable has a 9-pin D shell on one end and a 3.5mm plug on the other. I able to use N1MM's logger and one serial port for CW keying and PTT, using the RTS/DTR lines of the same serial port used for P3 / K3 rig control. There are certainly other options. This one works for me. I may eventually get another one for COM6-COM9. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Phil Hystad Sent: Sunday, December 16, 2012 2:54 PM To: elecraft@mailman.qth.net List Subject: [Elecraft] KPA500 Firmware Update and USB-Serial Cable ?

Re: [Elecraft] Possible firmware regression related to ACC2 IO / PTT=LO
Wayne, Thank you for taking the time to reply on a weekend. I'm not an EE, so I could have flubbed this test, but here is what I did: With ACC2 IO PTT=LO, KX3 power output set to 0.0W, and CW Skimmer monitoring the RX I/Q from the KX3, I plugged a brand new plug into the end of the short ACC2 cable supplied with the 'KX3-PCKT Cable Set' (no connection to the 590), then shorted the tip to the sleeve. The KX3 TX light came on as expected. I keyed up a short dit on the 590 at five watts (into a dummy load, for the record) and was able to see the dit show up on the CW Skimmer screen at the 590 TX frequency. Curiously, when I went to the KX3 right after reading your post, I could not immediately recreate the behavior. With no intentional change to the setup, it started happening again, which is when I did the experiment above. Let me know how you'd like me to proceed.

Re: [Elecraft] Possible firmware regression related to ACC2 IO / PTT=LO
Mark, When the KX3 is placed in transmit mode, it doesn't disable its RX I/Q outputs. These come directly from the receive mixer. Since the KX3's local oscillator is still active in transmit mode, too, a really strong signal (one that gets around the T/R switch) could still give you a strong enough response at the I/Q outputs to be decoded. It might vary with relative positions of the equipment, cables, etc. You should be able to prevent the decode by putting the KX3 into SPLIT mode, with VFO B moved well out of the target band. This way the LO would be shifted in transmit mode so that any decode would be out of the range of Skimmer. For example if you're on 20 meters, set VFO B to well below the band edge, say 13.8 MHz. Let me know if this works. 73, Wayne N6KR On Dec 16, 2012, at 5:13 PM, K7MJG wrote: Wayne, Thank you for taking the time to reply on a weekend.

Re: [Elecraft] K3 with SDR-IQ and external antenna for SDR-IQ?
Don tapped out: To receive VLF you will need a VLF converter. Well, that would be neat if Elecraft made one ... would integrate nicely. Then, since all I want to do is RX, I'd be isolated and not worry about frying the SDR-IQ. However, that's not the case, so I have to run an antenna straight into the SDR-IQ, and I have already done this twice. The first time, I was handily listening down at 17KHz with just the antenna to the SDR-IQ. Second time I was also xmit on the K3 and tuning the 450 ladder line. The SDR took a hit, I fear. Thus, I want to switch the SDR-IQ's antenna input OFF whatever existing external antenna she has WHEN I hit xmit on the K3. Call it a precaution. Won't have anything to do with xmit on the K3 nor Rx. Just the fact I want to externally close a relay that puts the SDR-IQ into 50-ohm lad when K3 xmit. This is essentially what we do with some high-end Pre-amps for EME. I was hoping somebody in the list had already solved the mechanics. The IF connection on the K3 is only an output, so the converter will connect to one of the antenna inputs to the K3. If it is to be receive only, you could connect to the RX antenna input or to the ANT1 or ANT2 connections of the KAT3, or to the RX port of the KXV3.

Far too many CBers are dedicated, consumate law-breakers, and that's been true ever since they were first given access to the 27 MHz band. So I strongly support FCC measures to make it harder for that group of outlaws to get access to equipment their licenses don't allow them to have. Admittedly, it was stupid to open an ionospheric-skip band to a supposedly line-of-sight service, but to call it a political problem is to blame a homeowner for leaving his door unlocked when vandals steal from him.

Re: [Elecraft] K3 Filters (again???!!) - Many Thanks
True Don, Without the second receiver it is pretty much a nothing to do the install. I have the second receiver too and have added filters twice since it was installed. The second time, the 2 meter internal module was also installed. Yes, it is not as simple as without additional pieces in the way but can be done and I didn't see it as anything other than a bit of a pain to have to remove and reinstall them.

If you are considering the subRX as part of your order, then I suggest you do not install the subRX until you have gotten a handle on the filters that you will want. Install those filters and then install the KRX3. The reason is entirely physical - the K3 main RX filters are beneath the KRX3, so that assembly must be removed to add additional filters to the main K3 RX. 73, Don W3FPR On 12/16/2012 4:41 PM, PETER HUTCHISON wrote: Hi, Many thanks to all who responded to my query about which filters to purchase for WJST modes.

In the USA, Hams have never had the privilege of operating radios in other services using their Ham license. For decades I carried a First Class Radiotelephone License (now a General Radio Operator's License) to operate standard broadcast and other transmitters, and I carry a Global Marine Distress Safety System license to operate the radios used at sea in addition to a Global Marine Distress Safety System Maintainer's license to repair those radios. Whatever you think of the CB service in the USA the FCC requirements for the equipment are entirely different from that of the Amateur Radio Service. 73, Ron AC7AC __ 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

As such, the FCC felt that if the new users can make communications in that mess, it's all theirs. The first CB users were rather law-abiding -- that went downhill in the mid-1960s. During the 1960s it was very common to hear such signals sweeping through the band. The main reason that we don't hear them today is that they were usually using unfiltered DC, and rich in harmonics. The third harmonic fell in the aviation bands, and caused harmful interference. The FCC had a very extensive effort to close down such devices - in fact, they were the only devices that an FCC enforcement agent could order closed down on the spot with no notice or hearing. The sweep was due to heat sealers (think waterbed mattresses) changing frequency as the material - the dielectric in a capacitor so to speak - changing as it heated up. Those devices were required to be used in shielded rooms or at other frequencies, usually the ISM microwave bands. So much for that history lesson - I was there. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon __ 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] Possible firmware regression related to ACC2 IO / PTT=LO
Wayne, Thanks for the great operating tip and for the explanation of the data path. Split works very well and keeps the CW Skimmer output pristine. For my own peace of mind - Can I assume, then, that it is safe to transmit 100 watts into a transmit antenna approximately 20 feet from the KX3's separate receiving antenna, and that as long as the KX3's PTT is activated and the KX3's TX light is illuminated, I'm not doing damage to my KX3? Incidentally, I'm very much looking forward to the KXPA100 and will be one of the first in line to order it once it is announced.

These come directly from the receive mixer. Since the KX3's local oscillator is still active in transmit mode, too, a really strong signal (one that gets around the T/R switch) could still give you a strong enough response at the I/Q outputs to be decoded. It might vary with relative positions of the equipment, cables, etc. You should be able to prevent the decode by putting the KX3 into SPLIT mode, with VFO B moved well out of the target band. This way the LO would be shifted in transmit mode so that any decode would be out of the range of Skimmer. For example if you're on 20 meters, set VFO B to well below the band edge, say 13.8 MHz. Let me know if this works. 73, Wayne N6KR On Dec 16, 2012, at 5:13 PM, K7MJG wrote: Wayne, Thank you for taking the time to reply on a weekend. I'm not an EE, so I could have flubbed this test, but here is what I did: With ACC2 IO PTT=LO, KX3 power output set to 0.0W, and CW Skimmer monitoring the RX I/Q from the KX3, I plugged a brand new plug into the end of the short ACC2 cable supplied with the 'KX3-PCKT Cable Set' (no connection to the 590), then shorted the tip to the sleeve. The KX3 TX light came on as expected. I keyed up a short dit on the 590 at five watts (into a dummy load, for the record) and was able to see the dit show up on the CW Skimmer screen at the 590 TX frequency. Curiously, when I went to the KX3 right after reading your post, I could not immediately recreate the behavior. With no intentional change to the setup, it started happening again, which is when I did the experiment above. Let me know how you'd like me to proceed.

Re: [Elecraft] K3 with SDR-IQ and external antenna for SDR-IQ?
KD7YZ Bob: Not difficult to do with the K3. Connect to the KEY OUT connector with wiring to the ground side of a 12v coax relay with a 50-ohm term on the NO coax connection. Connect the SDR-IQ to the relay common coax connection and antenna to the NC coax connection. The K3 will cause the coax relay to switch the SDR-IQ into the load when the K3 transmits. The SDR-IQ has to be on a separate antenna from what the K3 is connected, to ensure no RF goes to the SDR-IQ. If you already are using the KEY OUT for controlling something else then a NPN transistor is needed to isolate the relay coil from the other device. The NPN will invert the logic so you may need another transistor stage to maintain the same logic. Alternately you can make an logic isolator with two diodes such that current from the relay does not flow to the other device but only thru the K3 KEY ckt. (sounds more complicated than it is). 73, Ed - KL7UW __ 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
