Re: [Elecraft] KPA100 recommended max power for digital modes?
Well-protected is not quite the same thing as continuous service or maximum linearity. The KX3 is fine at 10-12W for CW or SSB, but people generally run it at 3-5W for FM or digital modes. Of course, when you need the juice, you need it, regardless of mode. wunder K6WRU On Feb 21, 2014, at 11:04 PM, Jim Brown j...@audiosystemsgroup.com wrote: On 2/21/2014 7:43 PM, WA7SPY wrote: I was looking at the operating manual online and did not see any recommended power setting for operating the amp with digital modes. Elecraft output stages are very well protected. In general, I feel comfortable running them balls to the wall with keydown modes, with all the lights lit. With well matched antennas, I run keydown modes at full power. If the output stage gets warm, the fan will run faster, and if that isn't enough, the rig will back off the drive. Remember that the WSJT modes are weak signal modes, NOT low power modes. There is a big difference. We may get lots of distance per watt and be happy with QRP for easy paths, but for the most difficult paths (EME, transcontinental 160M), great digital ops pile on the watts and use their best antennas. I do a lot of QRP, but I also know when to turn on the big amp. :) 73, Jim K9YC __ 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 -- Walter Underwood wun...@wunderwood.org __ 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

[Elecraft] Multiband end-fed dipole with KX1
Hi gang, I would like to find a 40/30/20 meter end-fed dipole I can run with my KX1 and its tuner. (I'm not crazy about linked dipoles for a number of reasons.)

On 2/21/2014 7:43 PM, WA7SPY wrote: What is the recommended max power setting for the amp using PSK31 with a KX3? In the K3, the limiting factor in some digital modes (notably PSK) is not thermal capability of the radio or amplifier, it is linearity. The linearity limit depends on the particular digital mode in use, and it may also vary depending on the mode used in the radio. For PSK31 and its higher-speed brethren, using the radio's DATA A mode, power settings no higher than half the maximum power rating of the transmitter should be used. This will ensure that the maximum instantaneous peaks of the transmitted signal are not clipped (in PSK these peaks can be up to twice as high as the average transmitted power). I can't speak from personal experience for the KX3, but given the similarity in the way the transmitter power is controlled, I would expect it to be the same as the K3. Using the KXPA100, keeping the power setting below 50 watts should avoid non-linearity. 73, Rich VE3KI __ 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] Multiband end-fed dipole with KX1
Paul, I run an EARCHI Matchbox with 44 feet of wire. It is resonant on 20m (no tuner) and the SWR is below 3.5:1 for the frequencies between 7 MHz and 25 MHz so you can tune 40-12m. I have no problem tuning it with my KX3 ATU. I am not sure the KX1 ATU will handle it but I am thinking it does. The EARCHI matchbox is good up to 100 watts - so it is both versatile and robust. I have gone to this antenna instead of the PAR 40-20-10. It also tunes 30m and has been my go to antenna for 30m for a long time at my QTH. It cost $35 to build with a kit from EARCHI and takes about 10 minutes.

Re: [Elecraft] (no subject)
I would recommend the Amp first for two reasons. One, you need the power. 10 watts is enough to make a lot of contacts, but it will leave you disappointed a lot of times when you will want to make the contact. A lot has been said for QRP and if you want a challenge it will certainly give you one, but you will find that people will avoid rag chews because they can' get solid copy and you will miss many contacts because the other party can't copy you. The second reason is that the amplifier is deeper into the K3 than the tuner and the assembly is easier with the amp first. The tuner is located at the corner of a K3 and is easy to add later. But both are great additions, particularly if you are not using an external high power amp and if you can afford the expense I recommend both of them as soon as possible.

Re: [Elecraft] KPA100 recommended max power for digital modes?
I don't think that Elecraft recommends any particular power. The amplifier will put out full power with acceptable distortion, but the lower quality receivers of others will easily overload and if you use more than a few watts it will prevent the use of the pass band by your neighbors and you will not be popular with them. They will tell you as they all want to be in the same SSB pass band so that they can see everybody at one time. Elecraft can't do anything about the quality of their competitors receivers.

[Elecraft] KAT-500 behavior under firmware 1.58
Greetings, Here is a little feedback on the new KAT-500 firmware. I installed version 1.58 last night and was using my 160m capacitance hat vertical antenna and observed what I think is strange behavior. First, I admit my 160m cap. hat vertical is not an optimal antenna. Previous versions of the firmware however, produced acceptable matches. Version 1.54 was a little better by introducing the finer step search. The version 1.58 firmware however produces worse results in my case. The tuning passes, the clickity-clack search, is clearly different on 160m. The KAT-500 now finds no good match in auto mode. I place the KAT-500 in manual mode and using the utility software set previously used capacitance and inductance values. Now the KAT-500 goes sometimes into bypass mode (I have no KPA-500), drops setting values with an audible click, and some times when I checked the utility it has gone far away in capacitance and inductance values without a clickty-clack tuning cycle. My K3 used to be able to produce nearly full power with its super ALC method of power control. According to my Palstar PM2000A power meter, not so much anymore, as it behaves now like traditional power fold back on 160m. It appears something is interacting.

Re: [Elecraft] Multiband end-fed dipole with KX1
Good Day Paul, My first rig was a KX1 and I ran an end-fed wire (34' as I recall) with three counterpoises. It worked on 20, 30, and 40 quite well. It wouldn't load on 80, but I made QSOs with it anyway. A year or so later I bought a KX3 and ran the same antenna with good results. Then about 6 months ago, I bought the EARCHI EFHW. I'm using the suggested setup--30' wire to the matchbox with 25' of coax.The KX3 loves it and it loads 6 though 80 FB--160 not so well. The only drawback is the counterpoise. Just for grins I took out the trusty KX1 and tried it on the EARCHI, The AT didn't like it. SWL was 2.0 where with it was 1.0--1.3 consistently with the simple wire-counterpoise setup. So, maybe I need to lengthen the wire as another poster noted. Just FYI see http://www.sotabeams.co.uk/efhw/ for a discussion of EFHW. 72 John K4ARQ On Sat, Feb 22, 2014 at 5:59 AM, PGSchreier pgschre...@swissonline.chwrote: Hi gang, I would like to find a 40/30/20 meter end-fed dipole I can run with my KX1 and its tuner.

I have had just the opposite results with v 1.58 My amp is an AL-811, I run it at about 300-400w on 160m My 160m antenna is a 7' tall HiQ screwdriver antenna (also with a top hat) @ 20' with 16 radials each 13' long on my apartment roof. With no tuner my SWR on 160m ranges from 2.0:1 to 4.5:1 With v1.54 I was unable to run the KAT500 in Auto it would tune just fine and then while talking it would randomly fold back and start a search for an elusive low swr point With v1.58 I am able to find a stable resonant point yes at first there was a major 'clackity-clack' search, which resulted in a point 'close' to resonant. But if I immediately taped the [TUNE] button again, there is a much quieter, shorter search, that resulted in a stable tuning point in AUTO. I can then enjoy my 2 hr morning ragchew with out any retuning. The next morning when I tune up there may be a brief quiet retune, but that is caused by the different overnight moisture changes on the roof. Once that initial retune takes place it's once again stable. ymmv On 2/22/2014 8:10 AM, DeYoung James wrote: Greetings, Here is a little feedback on the new KAT-500 firmware.

Re: [Elecraft] Multiband end-fed dipole with KX1
I have a home brew 40/30/20 end fed half wave vertical I've used for several years with my K1. 33 ft long and supported with a MFJ fiberglass pole, it has a loading coil 6 ft from each end. 20 m with the coil shorted, 30 m with a tap selected and 40 m with the entire coil in the circuit. You have to haul the antenna down to change bands but that's easy with the MFJ pole. The tuner is a tuned tank with a 6 turn link tapped on every turn. The coil and link are wound on a 1 in. toroid. It will tune the antenna to 1:1 SWR on all 3 bands. It will handle about 15 watts before it starts to arc. :-) I can put together the details if interested. 72, Brian, K0DTJ On Feb 22, 2014, at 2:59, PGSchreier pgschre...@swissonline.ch wrote: Hi gang, I would like to find a 40/30/20 meter end-fed dipole I can run with my KX1 and its tuner.

Re: [Elecraft] KPA100 recommended max power for digital modes?
For PSK-31, you really want to run the minimal amount of power necessary. Remember that the entire PSK-31 subband fits in your receiver filters -- you don't tune the VFO at all. If you transmit a strong signal, and propagation is good, I'll be able to work you, but when my receiver AGC cuts in all the rest of the PSK-31 stations on the band will go away. If I happened to be working one of those other stations, my QSO is over. As a rule of thumb, you don't want to exceed half the output power, unless the amp is rated for 100% key down. Monitor the temperature. 50 watts is a lot of power on PSK-31. 73 -- Lynn On 2/21/2014 7:43 PM, WA7SPY wrote: I just ordered a KPA100 with the auto tuner for my KX3.

[Elecraft] (no subject)
Good points: JT-65 is 100% duty cycle unlike CW or SSB that are much lower duty cycle. The issue is dissipation power in your finals. I run JT-65 with 1300w and theoretically the 8877 can dissipate 1500w so I am fine (the caveat is the 8877 needs very good air cooling). With no air the 8877 quickly fails with only filament voltage applied (5v-11a). QRP on 2m eme is generally considered anything under 600w or less than two yagis. That is a very weak signal when transmitted half-million miles roundtrip to the Moon. I have made JT-65 eme contacts using four 10-element yagis and only 150w...definitely QRP. Likewise, I can run 20m psk at 12w out of the native K3/10 into a triband yagi with good results. But the dissipation area in the KX3 is so small I would lower this to 3w. The Elecraft radios will quickly tell you if you are exceeding their abilities! On the other hand I over-built my 300w PA by adding a fan to it can be run to the wall at max power. 73, Ed - KL7UW From: Jim Brown j...@audiosystemsgroup.com To: elecraft@mailman.qth.net Subject: Re: [Elecraft] KPA100 recommended max power for digital modes?

Elecraft output stages are very well protected. In general, I feel comfortable running them balls to the wall with keydown modes, with all the lights lit. With well matched antennas, I run keydown modes at full power. If the output stage gets warm, the fan will run faster, and if that isn't enough, the rig will back off the drive. Remember that the WSJT modes are weak signal modes, NOT low power modes. There is a big difference. We may get lots of distance per watt and be happy with QRP for easy paths, but for the most difficult paths (EME, transcontinental 160M), great digital ops pile on the watts and use their best antennas. I do a lot of QRP, but I also know when to turn on the big amp. :) 73, Jim K9YC 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.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
[Elecraft] [W2] W2 on 630m band?
The specs for the W2 only go down as far as the bottom of the 160m band. From the schematic it would appear that the only thing on the Low Power Sensor that might limit it would be the input sensing transformers. Will the unit work down on 630m with out loss of accuracy?

I have used this set-up several times at various hotels... last time just the day before but in different city. (Sunny San Diego first of week, Drizzly Portland, OR now... Wish some of the rain would head further south into Reno for drought relief!! I have MINIMUM of S10 to sometimes S30 noise level - and any time I do get some type of voice it is all pretty garbled. Checked mode, LSB/USB - all connections several times, same on different bands... and when I checked WWV on 5 I could hear what I think was local AM station a bit clearer! Just trying things I reloaded a saved config file, even tried EEINT and reloaded again - no change whatsoever. Well, sun came out late this afternoon.. and one can see more than 100 yards...and across the freeway stands 3 large towers!!! Maybe this was overloading far beyond what the KX3 ATU can handle? as I read somewhere it has broadcast filters built into the ATU.

Re: [Elecraft] Multiband end-fed dipole with KX1
I have had success using an End-fedz multi-band antenna for 40 and 20. The same concept would work to add 30 meters as well. The End-fedz uses a stub to achieve resonance on 20 and the full length for 40. Another stub for 30 should work just fine. They are made and sold by PAR Electronics http://www.parelectronics.com/end-fedz.php I use on regularly on 17 meters and its performance is indistinguishable from a dipole. PAR Electronics also sells a 3 band model for 40, 20 10. They are well made and reasonably priced. I bought a bunch of big toroids and I intend to see if I can make some that will handle the output from the KPA500. That will be a summer project. Of course, you can build you own for peanuts if you have a suitable toroid and some wire. 73, Doug -- K0DXV On 2/22/2014 10:09 AM, Jim Brown wrote: On 2/22/2014 2:59 AM, PGSchreier wrote: I would like to find a 40/30/20 meter end-fed dipole I can run with my KX1 and its tuner.

Re: [Elecraft] KPA100 recommended max power for digital modes?
Hi Glenn, I started using PSK31 many, many years ago, when it was first introduced by a ham in the UK. It was made very clear to operators that minimum power should always be used for a QSO. It was suggested that more than 10 watts was excessive. As mentioned in one of the other replies, many transmissions can fall within the receiver passband when using this mode. If you, or anyone else uses much higher power, that strongest signal will take over the passband on most receivers, spoiling other QSOs that are going on at the time. I have noticed over the past five years or more there has been a steady increase in the power being used by thoughtless or unknowing operators. As a result of this power creep, I have drifted away from a mode that I once thoroughly enjoyed. With your KX3, you should not normally need an amp to use PSK31.

When I revealed my power level, many ops asked why I was running only that much power. So the push for higher power has been going on since shortly after the beginning of PSK31.

Re: [Elecraft] KPA100 recommended max power for digital modes?
When I went back to New Hampshire last Christmas, I decided that the trip would be a rag chew trip. Since the only radio I had was the Small Wonder Labs PSK-20 -- The K3 is too big to carry and I don't yet have a KX3 -- it had to be rag chewing on 20M PSK. I found a number of people to chat with and had a good time on the radio. I have a few thoughts on how to encourage rag chewing. Since people are used to the 5NN QRZ type of interchange, start chatting early in the QSO. I use macros for the boiler plate -- name, QTH, and call signs and use the keyboard for everything else. I'm lucky that after 40+ years as a computer programmer, I can type quite rapidly. Don't worry about typing slowly however. Rag chewing isn't a contest or a DX pileup. In my first exchange after exchanging call signs, I try to give meaningful signal reports, I'll start with: Hi OM, you are 569 569 569 and then run my QTH macro. If the other OP has already sent a name I'll use it in place of OM. Later in the QSO, if the other OP has already described the station, I'll try to include something about his station when I describe mine. By then we should be ready to branch out and talk about ARES/RACES, contesting, DX, WX, family, Christmas dinner -- anything that might come up. It doesn't always work, but then just move on and do/answer another CQ. As to being overpowered by strong stations, the K3 with a 250 Hz filter works wonders. However, for me, the real problem stations have been local running well under 50 watts. When you're in the target of a beam 1/4 mile away, it doesn't take much power to overload the A/D converter driving the computer. The PSK-20 doesn't have any narrow filters like the K3 does, but in New Hampshire there aren't any close by PSK operators either. I rarely see any New England stations on my waterfall. (20 meters is that way. I had a devil of a time working Nevada from the Los Gatos too.) Now there are times and places for rag chewing. Contests, DX pileups, and rare opening aren't them. At times when it is appropriate, try to encourage it.

Re: [Elecraft] [K3] - Digital Modes Interface - Working Split
Joel, Since you mention using RUMped I assume you are using a Mac. On the Mac if you run cocoaModem in the wide RTTY mode you don't need to run more than one iteration of the software to copy both the DX station and the pile up. If you have the second receiver you can tell cocoaModem to use one of the waterfalls for the Left channel and the pile up in the Right channel. Works like a champ and has helped me more than a few times to find the last worked station and decide my transmit strategy from there. With this set up stereo input to the sound card is mandatory and one of the several reasons I don't have a Signal Link.

There is plenty of reason to be able to decode both the dx station and the callers. It is necessary to locate the QRG of the station currently working the DX in the pileup. The K3 with a sub-receiver makes it easy. I use N1MM set up with MMTTY under the C/ and another MMTTY set up under /Program Files. Each iteration of MMTTY can be set to it's own audio channel, i.e., left or right, under optionsset upmisc. Also, if you have a decent audio card in your computer, you don't need any interface, just a couple of 3.5 mm stereo patch cords plus a PPT connection (serial cable or USB adapter-Elecraft's works great) for full functioning two frequency RTTY. You can also work one digital format while monitoring another, for example working JT65/9 while monitoring RTTY activity. 73 Dave, K2YG __ 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 __ 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] KPA100 recommended max power for digital modes?
Thank you for all the replies they were very informative. In my original post I stated KPA100. It should have been KXPA100 my bad on my part. Most of you figured out what I meant. I agree about the hi and bye PSK31 QSO's these days. That being said I will say I have had some really nice rag chew QSO's lately on PSK31. I typically start turning my power down during a QSO to see how low I can go and still have a good copy. I do have my KX3 connected to a Hard Rock 50, 50 watt amplifier. I run the Hard Rock at 20 watts or less on PSK31. In regard to the KXPA100 my original question was to find out what the max output power would be safe to go to without causing damage to the amp. If I am correct the answer is the amp will protect itself and automatically throttle itself back if the temp to the finals gets too hot. Now in regard to the KX3 without the amp 2-3 watts is recommended for PSK31. What does 2 -3 watts driving the KXPA100 equate to for output power from the amp. I will be using the Elecraft cable set to integrate the amp. So from what I have read that means the PA menu is selected to on on the KX3. That means the power control on the KX3 is re-indexed. So does that mean it is safe to run in the 20-30 watt range with the amp without over driving the KX3 for PSK31?
