Re: [Elecraft] Shipping of KX2's
And with the K3 in 2007 the order placed in May was ready to be shipped the following January 2008. But the 2nd RX wasn't installed and was still not available, so I took delivery of the complete ordered radio nearly one year after ordering. In the mean time I had the privilege of getting acquainted with the K3 at VP6DX. As stated; the wait was worth it. 73 de Milt, N5IA -Original Message- From: Ray Sills Sent: Tuesday, June 07, 2016 7:34 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Shipping of KX2's Amen to that!

Re: [Elecraft] OT: CW Contest logging question
IMHO the power level report is relative only, similar to the year first licensed in SS. The main thing these ops are trying to do is SHORTEN the amount of time it takes to send the exchange. IMHO, NN which indicates 99, which is REALLY close to 100, which is in the LP entry classification, is about the shortest power exchange you could use. It also very recognizable in QRN/weak signal conditions. When the send the traditional leader at 60+ WP, and then at somewhat less speed for the power exchange, the NN is very recognizable.

Re: [Elecraft] K3 Spur on 160??!!
Mike, From my remote station which was operated by KY7M in the contest, I noticed the same thing from the AC0C RBN box. However, in this case the QRG of KY7M was 1.820.6 and the other recorded transmission by AC0C was 1.864.7, a 44.4 kHz difference. Your noted difference was 25.4 kHz. Perhaps someone smarter than me can figure it out.

For example, if you have the 2.8 KHz filter installed in RX1, but the 2.7 KHz filter in RX2, you will probably experience this (as I recall). If you can, try selecting a bandwidth while in SSB mode where both receivers will be using the same roofing filters (if they are installed), and see if the frequency shift suddenly disappears. I am not absolutely certain of the above, but I seem to remember that was what I experienced before I upgraded to the the new synthesizers many months ago. 73, Dale WA8SRA __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] (no subject)
I used my Eico 720 (1960 through 1965) in both positions once I 'graduated' from the Novice class in 1961. I had three crystals on 40 Meters which tripled to 15 Meters that were used in the CW bands. I constructed the Knight Kit VFO for use in the 'phone bands together with the Eico 730 plate modulator. The 6146 final produced a great 65 Watts of plate modulated AM transmissions. Memories!!!

Re: [Elecraft] Field Day tips
I concur with all of the tips except the saying “Don’t waste your time with SSB
on FD”.
And I will add that anytime you go above Class 2A there should be at least ONE
SSB station. You will note the quantity of SSB Q's by one SSB station vs. the
two CW stations in the listing below. All the ops, both modes, were high
level, very capable at their mode. The CW ops included high level contesters
N2IC, WB0O, NI5L and N5IA.
The case can be made that the SSB station performed at a higher level than the
CW stations. This is all with solar powered 5 Watt level transmissions.
The following is a listing of the stats for the national record set by the
Eastern Arizona Amateur Radio Society (EAARS) operation from 2005. This record
held for 8 years until broken by a New Mexico group this past year ('13).

The last detailed QSO/mode/band I can find is from the West
Valley Amateur Radio Association's in 2011. We were 7A (battery
QRP). We had 3 HF CW stations, 3 HF SSB stations, an HF digital
station, a GOTA station, a satellite station, and a VHF station.
While our prime goal for field day is to have fun, we have fun
by erecting the best antennas we can, trying to get as many
people on the air as possible, and ending with a good score. We
set the all-time record for 7A that year and have set a number
of other records for various numbers of transmitters in other years.

Note that while most of our points came from CW, significant
number of points come from phone and digital. As you get into
the larger number of transmitters, QRP digital and phone become
an important part of the mix. QRP digital is always fun and
gives good scores. QRP SSB is fun with good antennas and propagation.

Re: [Elecraft] OT---Sorta A New Version of Charlie on The MTAFrom Our Kingston Trio Days
My recently shipped Elecraft part arrived via USPS in three days time, from California to New Mexico, via who knows where. The United States Postal Service is a federal government agency. The authority for the creation of the Post Office is found in the U.S. Constitution at Article I, Section 8, which says, in part: The Congress shall have power to lay and collect taxes, duties, imposts and excises, to pay the debts and provide for the common defense and general welfare of the United States; but all duties, imposts and excises shall be uniform throughout the United States… To establish post offices and post roads; Yes, it’s in the same clause that allows Congress to tax us and to raise an army and a navy. US Postal Service workers are FEDERAL employees. The US Congress writes the rules, postal regulations and laws controlling the Post Office. a postal crime including graffiti on a post office wallis a FEDERAL CRIME. The U.S. Postal Service is, by law, an independent establishment of the executive branch. The agency doesn't normally use tax dollars for operations, except when it needs a loan to cover all the unfunded debt, it must, by Congressional act, get that loan from the US Treasury. The USPS CANNOT borrow money from a private lender. The Postal Service has been borrowing billions of dollars from taxpayers in recent years to make up shortfalls caused by declining mail volumes and a 2006 congressional mandate to prefund retirement health care benefits. If I destroy a mailbox, it is a federal offense. If I attack a mail person, it is a federal offense. If I rob a mail truck, it is a federal offense. And if your Elecraft part does not arrive in time, and does a 3-times-around tour of the good ol' USA, it is NOT a federal offense. 73, and enjoy the upcoming Sabbath day where there has NOT been any USPS mail delivery since 1912. de Milt, N5IA -Original Message- From: Scott Manthe Sent: Saturday, April 26, 2014 8:58 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] OT---Sorta A New Version of Charlie on The MTAFrom Our Kingston Trio Days Our tax dollars don't support the USPS. 73, Scott, N9AA - No virus found in this message.

Everything with a grain of salt. As in all Ham operations, it is LOCATION, LOCATION, LOCATION. The the station, and 3rd, the operators. And oh yeah; propagation.

See the 2005 score line at http://www.eaars.org/fd7qpstats.pdf and photos at http://www.eaars.org/05fieldday.html SSB was an integral part of the operation with one K2. That position made 822 Qs.

The PA3 and sub-receiver are sitting here but not built/installed yet. Everything seems to work fine - completed the TX gain calibration successfully, and the filter setup too, of course. However, I’m puzzled by the how the S-meter is behaving. It seems to be inversely proportional to the RF gain. With the RF gain all the way CCW, all segments of the S-meter are lit. With the RF gain at 12 o’clock, half of the segments are lit. Changing bands has no apparent effect on the S-meter reading, and it’s rare that any but the strongest stations has any effect on the meter. And, with the RF gain fully CW, a few segments are lit (depending upon the noise level in the band). This seems backwards to me, but this is my first HF rig, so maybe it’s supposed to behave this way? Maybe I have some config setting messed up? Thanks in advance for any light you can shed on this!

Re: [Elecraft] K3 RemoteRig
Jim and Iain, IMHO the cure for perfect control of the keying speed is to use a Winkeyer for your paddle connection and then connect the Winkeyer to pins 4 8 of the I/O RJ-45 jack on the rear of the RRC Control unit. Make the proper I/O and Keyer settings in the RRC Control setup and you're there. As I understand the manner of transferring keying from your RRC Control to the RRC Remote such that the vagaries of your Internet connection does NOT affect the keying of the Remote K3, the direct control and transfer of data has to be changed. The result is absolutely perfect keying on the Remote K3 so long as your Internet connection is NOT losing packets. It truly is a superb application. Having to give up the internal keyer capabilities of the K3, and the resultant display, is a very minor negative vs the truly remote operation that the Remote Rigs provide. This is, as said above, IMHO. Just a satisfied, new, short time user, and YMMV.

I can't tell the K3/0 to use the front panel mike and high bias, because the remote K3 follows every menu change I make at the local k3/0. I feel pretty dumb, but what is the answer.

Re: [Elecraft] OT: 2m beam orientation
When you travel our direction (winter time for you snowbirds) you are invited to utilize a very active 2-Meter repeater system known as the EAARS Network. Go to http://www.eaars.com/eaarsnetwork.html for information and map locations of the various nodes. 2 Meters is very alive and well in the southwest US.

Re: [Elecraft] Hello from K3 Owner
Doug, The individual QSO Parties are great to pick up contacts with the various states, and also the more rare counties in those states. From your list, the New Mexico QSO Party is this coming Saturday. Three weeks from this weekend is the 7th District QSO Party with your needed states of Idaho, Montana and Nevada being out in force on all bands along with all the rest of the 7th District states. And that same weekend the New England QSO Party will also be running so you will have the chance at many Maine stations. So nearly half your needed states will be out in force and LOOKING for contacts with guys like you within the next 25 days. Go to the web pages for each of those QSO Parties to read the rules for the exchanges, etc. For a look at how we do it for the 7QP, go to http://www.ws7n.net/7QP/new/PicPage.asp?content=2012_7QP and click on the K7EAR tab. Note the K3 radios in the CW Bus photo. Also see http://www.ws7n.net/7QP/new/PicPage.asp?content=7QPFOTOS_2009 73, and good luck with the quest. Congrats on getting back into the hobby.

With the help of some friends, I moved quickly. In March 2013, I aquired K3 #7232. I sold my ICOM 706MKII and a triathlon bike to get the rig. The K3 arrived in time for WPX SSB and I made close to 200 contacts in less than 19 hrs. I worked 45 countries. WOW! I've been really amazed how well 5 watts does with my OCF Dipoles. I am working DX and getting 55-59 reports consistantly. I have erected an set of Buckmaster OCF dipoles which I have put together with a WX0B Stack Match at my QTH. I have also put up delta loops for 40, 20, and 15m. Check QRZ for the info. I am getting really good results. I had been keeping up on some of my basic opoerating skills up the last 3 years with my QRP buddies on the NA3DX Field Day Team. From 1996 to 2001, I was mostly SSB LP and HP. Now, I am working more CW because of the features of the K3 and will likely expand into RTTY and PSK after I get better at CW QSOs. I am amazed with how much CW is going on. It seem significantly more now than prior to 2001. In January/February, I uploaded my prior 1998-2001 contest logs and in LOTW and got 70 countries confirmed imediately. I have chased down WPX 300 and DXCC is in the queue for approval with over 120 confirmed via LOTW and QSLs.I have worked 80+ countries since January, all QRP. I am looking for help to get WAS completed. I am looking for anyone using LOTW from the following states: Hawaii Idaho Louisiana Maine Montana Nevada New Mexico North Dakota Oklahoma South Dakota Tennessee West Virginia I work 6:30 am to 3:00 pm M-F with my day job, then coach HS track until 7pm EDT. Weekends I am more flexible. If you would be interested, send me an email at d...@ellmore.net and we can try to setup a schedule.

Re: [Elecraft] KPA-500 110 or 220?
-Original Message- From: Richard Fjeld Sent: Monday, August 06, 2012 9:53 AM To: elecraft posting Subject: [Elecraft] KPA-500 110 or 220? I have read that an Electric Meter (wattage meter) will run up the bill more if the load is not balanced across the two feeders in the meter. By running things on 220 Volts when possible, it may help to balance the load and the meter becomes more efficient for the consumer. YMMV Richard Fjeld, N0CE --- NOT TRUE! The kWh (kiloWatt hour = energy consumed [thousands of Watts] over a period of time [an hour]) meters are NOT designed in that manner. And, your Public Utility Commission (PUC) would NOT approve them for use if they were design defective in that manner. PUCs require periodic testing of ALL kWh meters to assure they are registering power consumed, within the State specified range (typically +- 1.5%), for loading across a single leg (120 V) or across both legs (240 V). In the past (and where they are still used) the electro-mechanical kWh meter typically would slowly slow down over time due to wear on the disc jewels and spindle, or due to dust affecting those same points. Most meters found out of tolerance are running SLOWER; an advantage to the consumer. But, the percentage of kWh meters found out of tolerance during routine testing is very small (less than 1 percent). And that 'out of tolerance' value typically is less than 2 percent. The electro-mechanical kWh meter is truly a marvel. It is a highly accurate, long lived instrument which operates in a relatively hostile environment for years without requiring maintenance. Today's electronic kWh meters overcome the wear/dust problem as there are no moving parts. However, change of component values over time may cause similar problems; either under registering or over registering. So, periodic testing of kWh meters is still mandatory. The main advantage of electronic meters is the capability of including remote reading, load monitoring, etc., which all contribute to a more efficient, accurate (no manual meter reading person) and less costly operation.

Re: [Elecraft] two k3's on the same band
Matt, The multi-op NI5T operation in the CQ 160 contests at the N5BG station are done in the manner you are inquiring about. We run THREE K3s, one running and two SP on Topband, all three transmitting with full 1.5 kW output power. Granted, we exclusively use Beverage antennas for receiving, and the Beverage field is at some distance from the TX antenna. We copy stations with the SP positions to within a few kHz of the CQing position. Many times we operate in full duplex on the same freq, with one of the SP positions listening on the CQ frequency in a different direction than the CQ position is listening. This allows us to listen in multiple directions with the Beverages. We do not and have never had any problem doing this with the K3s or with the lineup of FT-1000 MPs we previously used. Never a single instance of receiver damage while operating in this manner the past ~13 years. The KEY to successful in-band duplex operation is ISOLATION, either by polarity or physical antenna separation, or both. YMMV, and good luck with your trial. 73 de Milt, N5IA -Original Message- From: Matt Murphy Sent: Wednesday, March 21, 2012 12:24 PM To: Elecraft Reflector Subject: [Elecraft] two k3's on the same band Just wondering if anyone has any experience using two K3's on the same band (for example, one for running, one for mults in a multi-op single transmitter scenario).

Re: [Elecraft] Curiosity Only, somewhat off topic.
David, The standard residential service in the US of A is 120/240 Volts AC. It is provided by the center tapped secondary winding of the utility transformer. The center tap is grounded and becomes a Neutral such that in the home you have two 120 VAC legs, one from each of two ends of the secondary winding. The two legs are 180 degrees out of phase to each other, and separately are used with the grounded neutral to provide the 120 VAC service. For larger appliances such as stoves, ovens, hot water heaters, clothes dryers and Amateur Amplifiers, the current is sourced by connecting to both 120 VAC legs, resulting in 240 VAC being delivered to the appliance. No additional step-up transformer is required. There is no free lunch. The laws of physics cannot be changed. It is just a different scheme of power delivery which allows a grounded neutral to be carried to each small appliance or lighting fixture. I hope that helps a bit with your understanding.

Re: [Elecraft] AC Pole Interference
Poor connection in hot line clamps used for taps off a main line or for equipment connections, etc. are notorious for causing RF noise as well as creating fires and shock hazards in situations like Tom mentions. Hot line clamps are used where it is not cost effective to install disconnect switches. The older hot line clamps did not have spring loading, and in time, with wind vibration, the clamps had a tendency to loosen. Three things have been done to mitigate this problem of burning a tensioned conductor in two. 1. Hot line clamps now have spring loading. 2. Hot line clamps typically have a dab of oxide inhibitor in the mouth of the clamp as it comes from the factory. 3. Most utilities crimp install a Saddle loop on the conductor, and then connect the hot line clamp to the saddle. Then, if the hot line clamp connection fails it only burns the saddle loop, and not the tensioned conductor.

Re: [Elecraft] barefoot K3 in ARRL CW
K-3s ROCK. Doing a single band 40 Meter effort here in New Mexico. First night yielded more than 500 Qs and 91 DXCC entities. Outstanding performance. With some luck with mults from EU and AF I may make DXCC in one weekend. One BA station gave me a report of 5W. He sent an E-mail to me saying he is using an FT-817.

[Elecraft] Second RX and KBPF3
This past weekend I installed the 2nd RX in K-3 serial # 2922. As part of that installation I installed the KBPF3 board in the 2nd RX. The 2nd RX appears to be performing OK. All of the setup went OK with the exception of the KBPF3. When the K-3 is turned on I get ERR BP2. The Manual indicates the Problem is No response from KBPF3 option shift registers. The Manual indicates the only cure for this error is to *De-install KBPF3 on RF board. I am a bit confused with the suggested Troubleshooting steps.

[Elecraft] Stew Perry is a Great CW Event
And another tidbit to remember, .IF.. you really want to operate the most time possible and spice things up. The maximum operating time is 14 hours for a single entry. In most locales there is some good operating time outside of the 14 core hours. Here in SW NM near the Mexican border, sun-up is now at ~7:20 AM. Sundown is a few minutes before 5 PM. The folks at the more northern latitudes have a lot more good time in darkness. My core operating is done in the 14 hours between 5 PM and 7 AM when I use my personal station callsign at QRP levels. From 1500 Z (8 AM local) starting time Saturday morning I will operate for an hour or so at QRO with a club callsign. I will start again at 3 PM local (2200 Z) and operate 2 more hours of QRO. I will follow up on Sunday morning at 1600 Z (when the QRP operation ceases) for a final hour of QRO. This allows me to operate ~4 hours of QRO with the club callsign and the full 14 hours at QRP with my callsign. I make entries with both callsigns. This is not only legal according to the Boring ARC club rules for the contest, but is also highly encouraged by the Stew Perry organizers. If you don't have a club callsign available, borrow one from a friend. As the old DoubleMint gum commercial said, Double Your Pleasure, Double Your Fun. As long as you use two different callsigns you can operate with each one as a QRP, LP or QRO entry. You can also break up your time as you see fit, so long as there is no more than 14 hours with either callsign.

The exchange is your grid (like on 6M), and the score for each QSO depends on the distance between your grid and the other station's grid, as well as his power and your power. So you get more points for running low power and QRP, and you get more points for working low power and QRP stations. This is a great opportunity to exercise you K2 or K3 at any power level and have a good time. Even if you don't have a dedicated 160M antenna, with a decent antenna tuner, you can load up almost any random wire against whatever you can use for a ground or counterpoise.

Re: [Elecraft] OT: Pin migration in Type N connectors
Dave, That type you describe is non-captive, as the center pin is not an integral part of the connector body. The crimp on pin, and snap into shell type still leave some margin of error. If the tech gets the center conductor too long, there is a possibility of the braid portion not being inserted enough to get proper crimping action with the ferrule. Additionally, the longer center conductor and pin allows a space to be created between the foam dielectric and the dielectric between the center pin and the connector body. This MAY cause problems. YMMV, but if any install step or calculation which has to be performed by a tech can be eliminated, the percentages of correct connections goes up. Mis dos centavos.

Re: [Elecraft] Very Efficient Ear Buds
Same here yesterday when I particpated in a Show and Tell for Explorer Scouts at a camporee on top of a 10,000 Ft. mountain in AZ. We really had to search to get a couple of signals who were of strength and clarity to conduct an open air demonstration of HF communication. A K3 sitting on the hood of my Suburban running directly connected to the battery for power, and connected to a 20 Meter dipole in the clear, strung between two fir trees, found VERY few signals on SSB and CW. The group of ~35 scouts and leaders found it exciting to communicate directly via the ether with a station in eastern CO and OH (a 3-way). Some of the scouts were intrigued with the CW demo, and tried their fingers on the iambic paddles while listening to the dits and dahs on the K3 monitor. Hopefully we set the hook in a couple of them. This mountain is named Heliograph Peak, and was used in the 1880's by the US Calvary for relay communications via Heliographs between forts down on the desert floor. Hence the name Heliograph Peak. To demonstrate the method of communications from 130 years ago, we used mirrors to flash to pre-arranged parties in the City of Safford, AZ, 7,000' below and 20 miles away from us. This mountain top is also a modern communications site and we gave them a tour of the towers, buildings and electronic equipment. We showed them amateur VHF and UHF repeaters, IRLP, remote controlled base stations and APRS systems that our club has operating at this location. All in all a great day with a fine group of youth and their leaders. Just needed more signals on 20 Meters.

Re: [Elecraft] OT: Transformer oil in DL's
And I have to totally agree with Ken. I have the same experience. Career 40+ years in power distribution. If you really want the rest of the story, do a search on Google or other search engine for Death of Humas by PCB Polychlorinated Biphenyl's. I don't think you will find anything. Feeding hundreds of times a normal dose of PCB to laboratory rats or a LONG time period showed the following: Quote Polychlorinated biphenyls (PCBs) are among the most widespread and persistent pollutants in the global environment. Coplanar and noncoplanar PCBs have been shown to cause congener-specific apoptosis mediated neurotoxicity in rats. Very few, if any, such studies have been reported on human renal cell toxicity. The authors report here caspase-dependent or caspase-independent renal toxicity, as measured by apoptotic death induced by PCBs, depending on the planarity of congeners PCB-77 (coplanar) and PCB-153 (noncoplanar) in human kidney cells (HK2) in vitro. The authors have combined morphological and biological techniques to discover the relevance of apoptosis in renal proximal tubule cell death induced by these two PCB congeners. Treatment with both PCB congeners caused accelerated apoptosis in a time- and concentration-dependent manner. Based on our findings using human kidney (HK2) cells, there was more apoptosis-mediated loss of cell viability by non-ortho-substituted PCB-77 when compared to PCB-153. A significant increase of caspase-3 expression through immunoblot studies showed the involvement of apoptosis by PCB-77 compared to none by PCB-153. The broad-spectrum caspase inhibitor z-VAD-fmk showed increased cell death when treated by PCB-153, but not by PCB-77, confirming that caspase inhibitor induced a switch in the mode of cell death. It is reasonable to assume that apoptotic cell death in the renal proximal tubule cells treated by PCBs may have both caspase-dependent and caspase-independent pathways. They don't quote the amount of TIME and the CONCENTRATION. I cannot find record of, and have never heard of, a human being suffering death or even sickness due to normal exposure to fluids containing PCBs. However, by the Stockholm Convention worldwide (2001) and the US Congress in the USA (1979), billions of dollars have been spent testing, labeling, replacing and buring or destroying power distribution equipment which were contaminated with but a few PPM of PCB in the dielectric fluids. The capacitors, transformers and oil which were removed from the distribution system which I worked for are now buried deep inside a rock mountain in Nevada at a great expense. And the fluids which replaced the PCB fluids cost a whole lot more and were less effective (less dielectric strength). Do your own research and draw your own conclusions regarding PCBs.

[Elecraft] K-3, N1MM, MK2R+ setup assistance requested
Esteemed Reflectees; I have historically done my SO2R operating with a pair of FT1KMPs and a home brew black box constructed from the directions in the NA manual. I used NA as the logging program. It all worked VERY well. Recently I have upgraded the primary contest radios to Elecraft K-3s, and the logging computer to one which does not have com ports on it. I have also started using N1MM as a Windows base logging program. So, nearly the whole combination is new. I have been unable to get my black box to work with N1MM and and USB to serial adaptors. The reason for this message request is for someone out there to assist me so I don't have to totally reinvent the wheel with my new acquisition. I have taken the plunge and purchased one of the MicroHam MK2R+ devices. I have set it up as near to the instructions in the MK2R+ manual and the N1MM manual that I can discern. I find both manuals not totally in tune with the other's requirements and I am sure somewhere I have checked a box that shouldn't be or failed to check a box that should be checked. I have the radios talking to N1MM and I have both TX and RX audio passing through the MK2R+ box. What I have not been able to make work is the PTT and the audio codec recordings for SSB. I have not yet tried to set up CW or RTTY. So, after all that explanation, is there someone(s) out there who might have this combo playing that could give me some direction of what to look for that is causing the lack of PTT response and how to make the audio codec recordings play. I am using the Heil Pro headset. Ideally, I would like to call someone on the telephone who has this combo working and go over the setup step by step until the problem is discovered. Anyone out there fit the description? If so, reply to me directly with your contact info and availability timing. Thanks in advance for any assistance.

Re: [Elecraft] RX Test (long)
H I suppose I am in the category where my hearing is impaired. At least my wife informs me near daily that such is the case. I was the oldest of the 13 operators blessed with 7 early production K-3s to perform a task nearly identical to that described by David. The two youngest operators (one just recently married at that time) as well as the majority of the VP6DX DX-pedition crew are among the elite of current contesters. Thirteen opertors taking care of SEVEN operating positions 24/7 for nearly 17 days; non-stop, day and night, three modes, Topband through 10 Meters, on an uninhabitated atoll with generator power was the task. The results speak for themselves; both for the operators and the equipment employed. I did not and have not ever heard any of the other 12 operators mention anything about the perceived noise problem. Suffice it to say that apparently the noise does exist for some small percentage of K-3 users with very acute hearing. BUT, my point is that there was NOT a problem with this problem for the very wide range of age and capabilities of the VP6DX team. Likewise, I have never perceived such an annoyance or distraction with my personal K-3, or other K-3's that I have operated. There is a difference of some subtle manner re the transceiver RX sound that I had been used to with the name brand and model radios I had used for the previous 13-14 years. But it certainly is not detrimental; in fact I can say that it is advantageous to ME. That is my observation and report, and MHO. Happy New Year to all.

Re: [Elecraft] K3 :: NO RF out of HPA
Ian, Thanks for the reply. Yes, the PA is turned on in CONFIG. Another clue is when TUNE is invoked, the output power does not track the power setting. For example, with the power out set to 12 Watts, the actual power out in the TUNE position is 3.2 Watts. Then, if I turn the power set upward at the 13 Watt level, the relay cuts in the PA. The power out indicator immediately goes to the 13 Watt indication and will follow up to the 100 Watt level. But during this excursion there is actually NO Power Out. No one else replied with any ideas, so I suppose this is a brand new situation. At this point I will open the radio up and see if I can find any loose connections to the PA.

Re: [Elecraft] K3 Power supply
- Original Message - From: Merv Schweigert k...@flex.com I started to try and find the problem and using another receiver I find the Astron SS-30 is generating all sorts of noise. I have used this supply for some time and have not noticed the noise before. Merv, For weight considerations, the SS-30 supplies were selected for the Ducie Island expedition this past year. This problem you mention, or a very similar one, was evident during the VP6DX expedition from the time that Robin started making tests while underway on the Braveheart from ZL to FO. We added extra filtering internally. We grounded extensively. We cleaned the case cover screw holes both on the main chassis and on the cover to improve bonding to the cover. We were never able to make them clean. All supplies performed in the exact same manner. We were float charging small batteries to keep the K-3s and the ancillary equipment running while the gensets were being refueled and having oil changed. The extra capacitance of the battery helped with the DC filtering but most of the stuff was of a frequency that the battery and other filtering could not remove. And we couldn't keep it inside the case. The fact remains that the harmonics of the switcher were a very real problem for us, especially on the lower frequency bands. The most annoying situation was the harmonic signal moving around, slowly up and down the band such that we could not avoid it at times when we were in the middle of a tough one on 160 and were trying to dig it out of the noise floor. We had to wait until the birdie slowly slithered on by or many times I just reached and turned the SS-30 off during a difficult contact. 73 de Milt, N5IA __ 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

All receivers generate internal noise in their amplifiers. The goal is to make sure this internal noise does not compete with the received signal so the only thing that limits the ability to hear weak signals is the unavoidable atmospheric or antenna noise. Of course, the amount of antenna noise you hear depends upon the filter bandwidth used. Narrower bandwidths admit less noise. That's why narrow band modes (e.g. CW, PSK31, etc.) get through when wider bandwidth modes won't. In order to keep very strong off-frequency signals from overloading the amplifier stages in the receiver, the ideal receiver has as little gain as possible before the filters that set the selectivity. But any noise generated in the very first stages of a receiver (mixer, etc.) gets amplified along with the signal and appears in the speaker or phones. On lower frequencies (up to about 10 MHz) the antenna noise in the quietest locations is still relatively high. That allows a receiver for those frequencies to be designed for best dynamic range (minimum gain ahead of the filters) and still the antenna noise will dominate, even at the narrowest filter setting. So the ability to hear weak signals it limited solely by the antenna noise and not by the receiver's internal noise. On the higher frequencies, the atmospheric (antenna) noise drops dramatically. Depending upon the noise in one's location, somewhere between 10 and 20 MHz the noise generated internally in most receivers designed for optimum dynamic range on the lower frequencies will start to compete with the antenna noise. The K3 (and K2) are no exceptions. The answer is to add more gain near the antenna using a low-noise preamplifier that boosts the signal and antenna noise levels up above the receiver's internal noise. That's why the K3 (and K2) have built-in preamplifiers that can be switched in on the higher frequencies. Low noise refers to the fact that the preamplifier has low enough internal noise that it won't compete with signals down at the level of the antenna noise. In general, the quieter (lower noise) the preamplifier is, the more susceptible to overload it becomes. And you don't want more gain than necessary ahead of the receiver's filters. Every dB of gain added reduces the dynamic range by bringing all signals and noise up nearer the clipping point of the subsequent amplifier stages in the receiver. That's why the preamplifiers are switchable. Smart ops turn them off on the lower frequencies where they aren't needed. Indeed, that's why there's an attenuator. Under extreme conditions, attenuating all the signals - wanted and unwanted alike - provides greater dynamic range and better performance, as long as the antenna noise is still greater than that generated internally in the receiver. That's a very common situation on the 160, 80 and sometimes the 40 meter Ham bands for many Hams. It depends upon their antenna and the level of the antenna noise. The built in preamplifier in the K3 does a great job on frequencies up to 30 MHz or so but it's marginal for best weak-signal reception in many locations on 6 meters. That's why the PR6 was added. It's optimized for best 6 meter weak-signal reception under most circumstances by providing enough gain to bring the very low antenna noise and signals on 6 meters up above the internal receiver noise. Ron AC7AC -Original Message- Hi... The following request for information is not specific to the K3 (or even to Elecraft). Please craft your response to be generic. Despite being an active ham/contester for over 40 continuous years (but not being an ee), I just do not understand how a preamp works. It is not a smart device, so how does it know to amplify the signal and not the noise? I first used a preamp way back when (1960's) when I was a teenager...it was an Ameco job. It was more fun than useful, because I could give out big S meter reports. Later, when listening in the noise became more important to my style of operation, I never could notice a difference between putting the preamp on and just turning up the volume (many rigs with built-in preamps too). Sometimes, turning up the AF gain worked better

I also did my first contest with my new K3; the first since operating with the team of K3s at VP6DX. I also used separate RX antennas and the diversity feature. Lots of fun. I also worked 160 SB. BUT Berni, I don't see your callsign in my log. I heard lots of stations and country/zone mults that I didn't work. I need more elements on the TX antenna. Hi, hi!! Still, a somewhat casual outing from the Southwest corner of New Mexico yielded 214 Qs, 57 DX and 21 Zones for a claimed score of 38,064. I'll be looking for all of you in the ARRL 160 this next weekend.
