Re: [Elecraft] Newsletter suggestion
I have Mac mail set to strip all incoming images and other junk as well. However, I also have a button available to download the stuff, so if I want to see it before trashing a message I can. I haven’t used Pegasus for years. Maybe it offers the same user controlled option in some form?

[Elecraft] Newsletter suggestion
My email software (Pegasus) strips many different kinds of images, this is part of its way of keeping viruses out of the computer & one of the reasons I keep using it after 25 years. It does this with most bulk email like Kim Komando & best Buy for example. It does this with the monthly Elecraft newsletter as well. All I see are gray squares where the photo was formatted in the email. Most bulk emails coming in like this have a link to view the email on the web (usually at the top, sometimes at the bottom of the message) & if not, the gray squares have a clickable link where it takes you to the article in question. In this month's newsletter there were some things to see on the K4 but the photos did not come with a clickable link so I can't see the info. My suggestion is to have a web page of the newsletter available and that link attached to each email. 2nd best would be to have photos with clickable links. 73, Gary KA1J __ 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] KPA1500 RFI on 12m
Except for my 6M yagi, all of my antennas are non-resonant antennas.
My favorite is the 256 ft center fed wire {resonant at 1.825 MHz} with
a balanced feed. The balanced feed runs from the feed-point on the
antenna all the way to the hybrid Guanella 4:1 balun that sits on the
shelf just above the KAT500. The coax jumper from the balun to the
KAT500 is about 12" in length. Thus the balanced line comes in all the
way to the operating position. This configuration will work all
bands, 160M - 6M with ease. And there are NO RFI issues with the KPA500
and the KAT-500 at 500 watts.
I find most hams cut an antenna length by formula, leave a few inches to
trim, and then trim for best SWR. This does not make a resonant
antenna. A resonant antenna is resonant depending on its electrical
length based on frequency. SWR and Impedance should be addressed by
means than trimming the length. Height above ground affects impedance.

worked them of 24 of 37 slots and was on Clublog's stats number 20 in NA.
I'm pretty sure that I never have the commanding signal in a pileup.
BTW, I use a K3S without a second RX and I don't have a separate RX
antenna for 160, things everybody knows you must have to work DX.
IMHO, knowing how to use the hardware you have is more important than
having more hardware.

[Elecraft] P3 abnormal shut off problem
Hi. My P3 has started turning off a few seconds to a minute after I turn on my K3/P3 or when I then try to turn my P3 back on. I was watching and saw no error message like low voltage. Watching also the voltmeter on my K3 and stayed at 14.5 to 14.7 volts. dropped power supply to 14 volts and it still shut down. Did a tune and voltage was 12.8 then back to 14 then afterwards it shut off. Is my power supply not holding up properly? Will dig out a spare power supply next. 73, tom w7sua __ 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] K3 problem (vfoB knob problem)
The A and B knob each have identical encoders that use plug-in boards to the front panel PCB. Chances are that the encoder isn't connected anymore (got loose). Opening up the front panel should tell. Note that the A and B encoder are identical so you can swap them for testing. Note that assembly of the front panel is quite fussy with distance rings, etc. You are well advised to keep notes of how the front panel was assembled when you take it apart. It also makes sense to have the assembler's manual at hand. Recent adventures with swapping parts on an older K3 learned that the B encoder sits in a little deeper with the new VFO-B knob. As a result, in my case, the solder pins were touching (scratching) the front panel PCB. I fixed this by cutting the jumper pins flush and putting in some isolation, just to be sure. I don't expect any broken parts, but some disassembly required. When you disassemble / re-assemble, be GENTLE with the volume knobs, they are known to split on older serial numbers.

[Elecraft] K2 for sale
I have a 'brand-new' K2, with the SSB option, for sale, serial number 5507. Why 'brand-new'? I explain - I finished building the K2 about four years ago. All went well and the radio tested perfect except I could not get an exact alignment on 40 meters. I spoke to Don Wilhelm and he suggested I send it back to the factory for a checkout. I did and the problem turned out to be a faulty component, which Elecraft replaced. As long as the radio was at the factory I requested, received, and paid for a complete checkout and alignment of the K2. Unfortunately, during the three weeks the radio was at the factory I had a medical issue that prevented me from participating in the hobby that I loved since I was first licensed in 1951. So the radio sat on a shelf in a closet, as it does to this day. I never liked winding toriods so I had ALL the toriods and transformers professionaly wound. My actual cost of the K2 kit, with the SSB option, all taxes and shipping costs, the professionaly wound toriods, as well as the cost of the inspection and alignment by Elecraft was greater than $1200. I am asking $1000 for this carefully built, factory aligned and certified 'brand-new' K2.

Re: [Elecraft] KPA1500 RFI on 12m
I use a C3 up at 80 feet it works quite well. I have not really spent a lot of time on 12m, really no activity here to make it worthwhile but on 17m it works rather well despite not being a particularly good match. I fixed that by measuring the actual impedance at the end of my feeder then adding a foot or so of feeder and cutting a shorted stub to create a good match. In my case it's very close to perfect but anything less than 1.5:1 I would consider excellent. An antenna analyser and 5 minutes with the excellent SimSmith program can do wonders for your matching worries. Properly sorted at just the right point on the feeder with an antenna switch a tee piece and a few stubs you could probably get a good match on a bunch of bands though I suspect the losses might be a bit high if you try 40m, eek! The C3 on 17m certainly has directivity albeit 180 degree from the regular 20-15-10 antenna.

Re: [Elecraft] KPA1500 RFI on 12m
What is a big deal is using the KPA1500 on 60m unless you're using a dummy load or paper clip for an antenna. "The 60 meter band has special restrictions including the restriction of radiated power relative to the gain of a half-wavelength dipole antenna which is 100 watts PEP." We need to keep 60m, not loose it due to abusing its power limit. The KPA1500 tuner can achieve solutions beyond VSWR's of 3:1, but only if running reduced power. See page 18 of the Rev B manual for the VSWR vs. power curve. 73, Bill, K8TE KPA1500 S/N 116 -- Sent from: http://elecraft.365791.n2.nabble.com/ __ 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] KPA1500 RFI on 12m
"Not a big deal but there is something weird with the SWR detection in the KPA1500 which allows it to take the amp tuner out of bypass. " It also seems possible that the tuning solution change is triggered by "high SWR threshold". Read the Programming Reference information for commands ^HS; and ^STA; for more info. If this is the cause then setting ^HS0; may help. You will need to use the Utility to inspect and change the values. Sometimes we will accept less than ideal antennas when chasing DX and sometimes we get lucky.

Re: [Elecraft] KPA1500 RFI on 12m
In the KPA1500 utility I have the tuner bypassed for the whole 60 meter band. The tuner’s logic is detecting a high SWR and overriding the bypass selection. This happens at 30 watts forward power. The answer is to turn off the amp when on 60 and just use the radio’s tuner.
