Re: [Elecraft] QRP and contesting
That is pretty impressive. When I was first a ham, one of the locals was W7QYA, Flo, a school teacher not far away. I had managed to crank my speed up to 40 (with some struggle) but she said that was painfully slow for her. Her nominal speed was 65 wpm. I have yet to get much above 40.

[Elecraft] Good Natured Contesting Advice
>"When answering a CQ, send ONLY your call, and never repeat anything that the other station copied correctly. For example, if he sent your call correctly when he responded to you, don't repeat your call when sending your exchange." As I read the rules of the contest, sending your call is *required* as part of the exchange. >"And when you're the caller, never send the other station's call unless there's confusion about who's working who." Yes, I read that in the QST write-up, but. Sending the other station's call confirms that you have copied his call correctly. 73, Charlie, N0TT __ 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

Paul... Not really much to the radio setup. Your transmitted deviation is very important on 2 meters and so is the incoming volume level going to your soundcard. Unless you have an amp or a gateway station really near, that 3 watts may not be enough to make it. What soundcard are you using?

Re: [Elecraft] QRP and contesting
Funny story Last Field Day my son and a friend of his went camping with our group. Neither of them are CW operators (yet), but they did know the alphabet. They borrowed a MCU-controlled code-practice generator from another op and were competing to see who could copy single letters at the fastest rate. When they got stuck at around 20 WPM, I said, "how fast does that thing go?" It apparently would go much, much higher, into Morse nosebleed range. Just for fun, I asked them to set it up to generate random English text at 45 WPM. I decoded enough of it to convince them that this code speed was in my head-copy range. Then they started bumping it up another 5 WPM at a time--a challenge! I was in some sort of zone that day. Maybe it was the sunshine; maybe the idyllic sound of blue jays; maybe the 4-pack of White Claw I'd scored at the liquor store. In the end I managed to copy several words at 70 WPM.

Re: [Elecraft] Good Natured Contesting Advice
OK, here is a bit of view from the little pistol side. I made 135 contacts from a low EFHW antenna and 99W. I'm not loud. I'm a CW novice. I hear OK and send OK at 23 wpm. I practice and can hear simple exchanges up to about 30 wpm. I struggle with callsigns and complex words and phrases. I search and pounce by listening 2, 3, 4 or more times till I'm confident I have an exchange. Then I let N1MM+ and WinKey USB send my call and when appropriate send my exchange. I had a number of loud strong stations call over me, some while I sent my exchange, and some running ops abandoned me and took the loud station. OK. Wipe that one. Try again here or elsewhere, turn the big knob. Part of the game. 9⁸ Sometimes I was asked for a repeat with a question mark. I sent all again. Sometimes I heard noise or QRM/QRN and nothing specific and so I sent my entire exchange. If I hear a specific item, I sent that by hand. When I screwed up my hand sending I let N1MM+ send (not necessary often). One loud op sent "Dupe" so I checked and I had nothing similar in N1MM+. I moved on, but the next time I searched that band I got another DUPE. I sent NIL and got DUPE. We did that 2 or more times as I rotated through the bands until I memorized his call. The advice I hear in my clubs and here is work first worry later. But dupe checking works both ways, NIL means not in log and for whatever reason no dupe and he maùy lose penalty points and likely saved little time. None of this is an excuse to play in a big contest when you are not ready to play reasonably well. A contester's goal is to send and recieve as accurately and quickly as possible to accumulate the most points possible, understanding that too fast is slow, and too slow is not winning. I listened to a straight key op sending CQ SS at some 10 wpm high in the band on Saturday. I chose not to call because I'm terrible at slow code and it would not have been fun. If it had been later on Sunday I might have called. I wondered how many takers the op got? SS CW does not seem a good place for slow straight key, but it may have been an older op with a 30s-40s check. Dunno. Nothing wrong for trying, but expectations should be low.

Re: [Elecraft] Notice regarding K3S current-sense resistor power rating
Wayne,I do not have a K3S but how many firms have this type of contact between Chief Engineer and customer. Well done.73 Doug EI2CNSent from my Galaxy Original message From: Wayne Burdick Date: 10/11/2022 02:18 (GMT+00:00) To: Elecraft Reflector Subject: [Elecraft] Notice regarding K3S current-sense resistor power rating It has come to our attention that a 50 milliohm resistor used for sensing current drain on the K3S RF board is, at least on paper, underrated for the application. The resistor is R36, used in the low-current path that supplies 12 V to everything except the KPA3 100 W PA module.NOTE: On the K3, a leaded 2 watt resistor was used. On the K4, a surface-mount 2 watt resistor was used.So this issue only affects the K3S, which has a 1/2 watt resistor at this location. This was an oversight.According to our lead repair technician, only one RF-R36 has ever had to be replaced during service, and it was in fact stressed because of a short on the board. The infrequency of failure is probably due to the conservative power rating of the 1/2 W resistor. I would not expect adverse effects under typical operating conditions. The way you would know that the resistor had been damaged is if the indicated non-100 W PA current drain had gone up unexpectedly, or had exceeded the allowed range, resulting in a HI CUR warning either in RX or TX mode. Normally a basic K3S with no options will have an RX-mode current drain in the range of ~1.0 A, while the ATU and sub-RX options can bump this up to ~1.5 A. On key-down, the indicated current can be as high as several amps. The only way to definitively verify a damaged resistor, if there's no HI CUR warning, would be to place an accurate external ammeter in series.Even though we expect instances of damaged current-sense resistors to be very few, we will send a leaded, 2 watt substitute resistor to any K3S owner on request, at no charge.If you would prefer to have us remove the SMD resistor and replace it with the leaded one, you may send your K3S back to the factory. There will be only shipping charges (no charge for parts or labor).73,WayneN6KR__Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:elecr...@mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.htmlMessage delivered to turnb...@net1.ie __ 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
