Re: [Elecraft] KX3 Amp
I don't have the amp but would very much enjoy hearing comments from all those that do have them. I might add I do have other amps and a KPA500 as well but using it with an Icom radio for mostly 6m. 73, Fred/N0AZZ K3 Ser # 6730--KX3 # 5210--K2/100 # 6470-KAT100 P3/SVGA--KAT500--W2 Amps Elecraft KPA500 HF/6m--Alpha's 9500 HF--87A HF--Mirage B-5030-G 300+w--(2) B-5016-G's 165w 2m -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of KF5TEU Sent: Monday, December 30, 2013 10:25 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] KX3 Amp Just FYI, I got the Elecraft 100W amp in two or three weeks ago.

Re: [Elecraft] KX3 Amp
With all the banter about KX3's and amp's, on batteries for Emergency use. Please remember, that battery makers specify the AH figure, for a typical C/20 rate, (1/20th the nominal AH current value.) Some may quote it at C/10, check the data sheets for the battery of interest, they will often have example of typical discharge voltage curves, for various discharge rates too. That can be *Very* enlightening! Without going into specifics, 20A from a 7AH battery may on the face of it give you some 20 minutes operating (7 / 20 * 60) but in practice you'd be lucky to get even near half that of actual Practical Use of your amp'. Probably no more than 5 mins TX time at most before it all starts to collapse. The charge/discharge efficiency of SLA (and most other batteries) falls like a stone with high discharge currents, also, also the voltage is lower at high currents as the battery nears empty, but many high current loads (Amp's etc) don't work well (if at all) at those lower voltages, so in practice you get even less usable run time.. Try your intended battery with something else that is a similar load, while monitoring the voltage... For Lithium family cell's, they (should) have a monitor circuit that will simply cut off the load to prevent over discharge (and resulting thermal instability) leaving you totally dead in the water as it were. As others have said, if you don't already have the needed techniques, opt for some narrow band mode (the built in PSK31 if your CW is not good enough?) to get a message out if needed via as resonant as you can get it antenna.. Even 3W of that can be reliably decoded many 100's of miles away, on the right frequencies. Don't forget the counterpoise if using a wire. However, farmers fences can make good grounds, also antennas at times! :) (Avoid Electric fences of course!!!) A repeated short distress message (SOS or PanPan Medico?) including an international grid reference, sent on one of the QRP frequencies, I suspect would possibly result in some action, but I wouldnt garrantee it on HAM bands sadly.. Remember too, what is said somewhere in all mobile phone handbooks that I have ever seen (that no one ever reads) this device uses radio signals, that are by their nature unreliable, you should therefore not rely on this or other radio service for emergency call's. But what do most people cite for their ownership of a mobile 'phone? Use in an emergency! If you **NEED** such comm's, perhaps a satellite 'phone is more appropriate, and even they are not without issues. Or carry an EPIRB with you if you're hiking well away from anywhere. Activate one of them, even on land, and all heck will come your way in very short order!. Even a sat'phone and EPIRB are lighter and smaller to carry than a KX3, amp and battery... But best of all, tell people you trust more or less where you are going, and your planned route + intended return date/time, and whatever late tollerance figure you think, just in case of delays. Then, if you don't appear, or contact them from elsewhere by any means, they can call the cavelry out. Of course, if your plans change on the fly get a message back to them, to that effect... Enjoy the outdoors, but stay safe. If you have known medical issues (type one Diabeties for example) talk to your doctor before planning any extended trip out into the sticks, just in case. Given the choice, I'd prefer to ensure I can cary/find enough water food, also perhaps a simple bivoac shelter kit for any significant hike out, also any needed indiginous venom antidotes etc, than carrying any Ham Radio gear I think.

Re: [Elecraft] KX3 Amp
Which brings us full circle as to what is it you are trying to accomplish? The ham with a KX3 and a chuck of wire will do (OK) on a hill top or by the ocean-side. This works very well for the week end warriors etc. Add a solar panel and the duration goes way up. Add a resonant antenna not needing a ground and you gain again. Add a small amp and suitable battery with upgraded solar panel and you go up again. Add an RV with internal batteries, and the night goes on. Anyone keeping score?? Pick you battle and you will always be ahead. If you try to win the war with entry level, you lose. I personally pick my battles carefully and watch my allotted budget, I win.

However, if what you want is the ability to get a signal out at marginal propagation conditions, then a 50 watt amp if used frugally can get a stronger signal out. Several amps fall into this category with about a 9 dB gain in signal strength from 5 watts - and pulling about 7-10 amps of drain on the battery on TX - Tokyo HiPower HL45B, HFPacker, and Hardrock50. The latter 2 you have to build yourself. The Hardrock is only available used if someone is willing to part with theirs. Only about 100 of the Hardrocks have been built. Sales are on hold pending FCC certification. The Elecraft amp can also be tuned down for less power out and can be tuned to 100w if needed. You do have to carry enough battery to sustain the anticipated TX time. You will be surprised at how effective 5 or 10 watts can be and effort is probably better directed at effective antenna systems. 100w into a dummy load th at radiates (my way of describing a poor antenna) is a poor substitute for 10 watts into a resonant wire. Up high and in the clear is always better. I have always had better luck with wire in the clear than verticals on a picnic table in terms of reach.

Far better to LEARN how antennas work, learn CW if you don't already know it, and carry the wire and other light weight antenna accessories required to make reliable contacts with stuff you CAN carry. Putting some numbers to it, a 100W Elecraft rig requires 20A to transmit. A 7Ah battery will give you 20 minutes of transmitting time at 100W, but it will give you more than two HOURS at 5W. 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 __ 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] KX3 Amp
Much appreciated. This is what I found on these amps – Yes, I bought the dang Italian Amp because that is the ONLY one I could actually get BUT if anyone has the TEnTec (418 I think, 100 amp, DC powered , portable , new model )and wants to sell it (working as new, no glitches , decent price ).. let me know. TX - Tokyo HiPower HL45B – anything over 5 amps can blow the caps in this unit so some have put attenuators between the KX3 and amp HFPacker – won’t be available in time Hardrock50 – also not available immediately so I can test Ten- Tec – found new 100W model, looks perfect – once again – VAPORWARE – just like the KPA100 – much hype, much talk about availability , much “we’re just trying to get it perfect” – Nothing available and no real idea when it will be KPA100 – I think I’ve seen a unicorn but I’ve never seen a KPA100 that I can buy. Last December it was “ just a few more tweaks, parts in house, ready soon, blah, blah , blah “. OK, I want it perfect too but nobody can vouch for it , try it or buy it based on a promise. This is exactly what I want – in theory. In “theory” by the time I get back from my trip I’ll have bagged a lion , a zebra , several large plains game species , a huge WoBo and a gorgeous , young South African gold mining heiress who wants me to handle all the profits from her multi-billion buck empire.

Re: [Elecraft] KX3 Amp
Thanks. Just to try it I bought an HLA on Amazon, with fans. I have the built in optional Elecraft tuner, some other 100W autotuners and a few antennas that just might be resonant at the right freq:, 10M during the day, 40 and 80 later on. Hopefully we just chat on the 2M until over 20-30 miles out and base has a big antenna (beam they tell me) to pick us up when farther out (we hope). I'll add a fan switch and a temp. sensor from a PC unit I have. Fans burn juice so I will keep them off unless needed. I really want the Elecraft KPA100 but I also want a guaranteed trophy without doing a canned hunt. Which is more likely to happen by end of July I wonder?

HLA 300 (and probably 150) have RF sensing PTT and automatic band switching. They also have decent IMD is not driven to full output power. HLA 300 is about 25-30 db IMD when driven to 150-200 watts (5-7watt input) and cost under 500 USD.

The HF Packer is not a 50w amp. It's about 45w at 160m, and then steadily less as you go up in frequency (40w for 80m, 35w for 40-20m, 30w for 17/15m, 25w for 12m and about 20w for 10m). It doesn't support 6m. These numbers come directly from a graph in the HF Packer manual. John AC0ZG On 6/30/2013 10:18 PM, Ariel Jacala wrote: Hands down the KXPA100. It isn't out yet - shipping in August but offers the greatest flexibility with a tuner and portability. The Hardrock is ~$260. It is only available to members of the Yahoo group right now. It is 160-6m and generates a solid 50w from 160-10, less on 6m. I own a Hardrock and it was a difficult build but Jim Veatch helped me out a lot - WA2EUJ. No tuner though so you will have to invest in a ZL100 or equivalent. The Elecraft tuner is faster and tunes a wider range. Size wise is only slightly smaller than the Elecraft 4 1/8 wide and tall by 7 deep. The TenTec is a larger amp - $800 plus a 100w tuner. The THP HL45B is a solid performer at about $450 from HRO. Again you need an outboard tuner. You have to manually switch bands. If you don't it will go on standby - a self protective feature. I played with a THP for a while and it works well. You can get one used - not easy - for about $250-$300. There are the RM Italy variants - beware do no t overdrive - IMD artifacts - HL300B is the model - only drive to 100W - I have no experience with this amp. These are not certified by the FCC. Some people have had great luck with the Juma 100w amp and some on the reflector may have owned one or built one. The Jumas can be programmed to band switch with the rig. Again - it needs an external 100w tuner. So here are your choices: Juma 100w - no tuner - band switches with rig automatic - FCC certified Hardrock 50w - no tuner - manual switching - not FCC certified TenTec - 100w - no tuner - band switching with rig automatic HFPacker - 50w - manual swiching KXPA100 - 100w - tuner - automatic band switching - FCC certified THP HL45B - 45w - no tuner - manual switching (except for FT817) - FCC certified THP HL100B - 10w - no tuner - manual switching - not FCC certified RM Italy HL150 - 150w - no tuner - manual switching? not FCC certified RM Italy HL300B = 300w - no tuner - manual switching? not FCC cerified Antennas Too many to list Personal favorites - G0GSF- multiband dipole - 4 bands are OK w/o a tuner, EFHW - cut to 45 ft with EARCI matchbox KX3 tuner will match 80-10m Ariel NY4G Sent from my iPad On Jun 30, 2013, at 11:39 PM, KF5TEU [hidden email] wrote: While all these posts have good advice for a bc trip , I really just want the KX3 amplifier.

Re: [Elecraft] KX3 Amp
There are a lot of emergency situations that benefit from two-way communication. PLBs are great for sinking ships, but not so good for distinguishing between a wildfire and a medical emergency. I've dealt with a few emergencies in the backcountry. On one trip, we had both a wildfire and two medical situations. You can draw your own conclusions about heading into the backcountry with me. :-) Hey, I wrote a long blog post about that: http://wunderwood.org/most_casual_observer/2011/10/emergency_communication_in_the.html wunder K6WRU On Jun 30, 2013, at 5:32 PM, Ariel Jacala wrote: Well, in that framework - I would have to agree that the PLB is better .

Re: [Elecraft] KX3 Amp
I like Walter's paper and risk management approach and also with the philosophy of needing 2 way communication to manage logistics. Personally, IMHO, the Satelite phone rental is probably the most effective way. I personally don't travel more than 10 miles from the trail head so I have gotten by with HT/GPS/APRS and a small HF rig. I also carry a standalone GPS for trail maneuvering. A coiled up twin lead J-pole is quite effective and can be configured for 2m or 11 meters. When I was on Pisgah Mt in NC, I had no problem hitting the repeater on Caesars Head in SC, which gave me an effective range of 100 mile radius with that J pole strung up on a tree and the TX on the HT at 5w. Preparation and redundancy is key - even backups for backups. He who does not have a backup plan better be really lucky. Waiting patiently for the Elecraft 2m module.

Re: [Elecraft] KX3 Amp
PLBs actually aren't legal for sinking ships (or crashing airplanes), there is a different category of device for that. Personal Locator Beacons are meant to do one simple task: summon help in an emergency. Calling someone to tell them you're at a different trailhead is not an emergency. If I'm off in the backcountry, I'd suggest that a medical emergency and risk of being overrun by a wildfire aren't that different. If you want to report a wildfire that isn't threatening you, that isn't an emergency, and if it takes you a bit to get an antenna up, and find someone to relay a message, then by all means pull out your KX3 and a random bit of wire and tell someone. A satphone (according to your post) is about $120 for a given outing. A PLB is about $250 for five to seven years. It's good to have more than one tool in your toolbox. -- Lynn On 6/30/2013 5:41 PM, Walter Underwood wrote: There are a lot of emergency situations that benefit from two-way communication.

Re: [Elecraft] KX3 Amp
For Maritime you want an EPIRB (Emergency Position Indicating Radio Beacon). Contacts the emergency network via satellite with the vessel's identification and location and then provides a 400 MHz beacon for rescuers to RDF right to you. They activate automatically when coming in contact with salt water in case no one has time to activate it in an emergency. I'm surprised that the news reports about the sailboat missing between New Zealand and Australia has not mentioned one. They've been standard for over 20 years. A blue water sailor without one is as bizarre as not having a life jacket on board. I will use 100 watts for emergency communications (on land) wherever I have a motor vehicle to power the rig. Otherwise, after 60+ years on the air, I cannot imagine a scenario where an SOS on CW or MAYDAY on SSB won't bring up a reply on some band at any hour of the day running 5 or 10 watts. Indeed, the big issue is getting a response from halfway around the world when one wants a call to local emergency services! 73 Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Lynn W.

Nothing lke real time phone to keep a trip safe and productive. 2M would be nice but we have seceral small HT's for that.

You can draw your own conclusions about heading into the backcountry with me. :-) Hey, I wrote a long blog post about that: http://wunderwood.org/most_casual_observer/2011/10/emergency_communication_in_the.html wunder K6WRU On Jun 30, 2013, at 5:32 PM, Ariel Jacala wrote: Well, in that framework - I would have to agree that the PLB is better .

The Personal Locator Beacon frequency is monitored by two sets of satellites -- a constellation of low-earth-orbit satellites that can determine location, and a few geostationary satellites that see a wide area of the planet, looking straight down at the surface of the earth. The latter can read the GPS on the PLB. The signal goes straight to search and rescue folks, and the beacons are registered so they know exactly who they're going to be looking for.

Re: [Elecraft] KX3 Amp
I appreciate the low power is better for longer advice but..this is for that crucial 5 min. of comm. when low power just doesn't work. We have several 13500 MaH/5A power packs that combine for 20 plus amps and weigh about 1lb. each. We also have the vehicle batteries , aircraft batteries and 2 field solar 1KW ( I think, not mine ) chargers with built in Li,ion batteries. I hope it's just 5 min. at 5W 3 times a day for 4 weeks but...JIC , the 10db could be a real life saver. So , I have the PLB , the sat. phone and the GPS.

Re: [Elecraft] KX3 Amp
Hands down the KXPA100. It isn't out yet - shipping in August but offers the greatest flexibility with a tuner and portability. The Hardrock is ~$260. It is only available to members of the Yahoo group right now. It is 160-6m and generates a solid 50w from 160-10, less on 6m. I own a Hardrock and it was a difficult build but Jim Veatch helped me out a lot - WA2EUJ. No tuner though so you will have to invest in a ZL100 or equivalent. The Elecraft tuner is faster and tunes a wider range. Size wise is only slightly smaller than the Elecraft 4 1/8 wide and tall by 7 deep. The TenTec is a larger amp - $800 plus a 100w tuner. The THP HL45B is a solid performer at about $450 from HRO. Again you need an outboard tuner. You have to manually switch bands. If you don't it will go on standby - a self protective feature. I played with a THP for a while and it works well. You can get one used - not easy - for about $250-$300. There are the RM Italy variants - beware do no t overdrive - IMD artifacts - HL300B is the model - only drive to 100W - I have no experience with this amp. These are not certified by the FCC. Some people have had great luck with the Juma 100w amp and some on the reflector may have owned one or built one. The Jumas can be programmed to band switch with the rig. Again - it needs an external 100w tuner. So here are your choices: Juma 100w - no tuner - band switches with rig automatic - FCC certified Hardrock 50w - no tuner - manual switching - not FCC certified TenTec - 100w - no tuner - band switching with rig automatic HFPacker - 50w - manual swiching KXPA100 - 100w - tuner - automatic band switching - FCC certified THP HL45B - 45w - no tuner - manual switching (except for FT817) - FCC certified THP HL100B - 10w - no tuner - manual switching - not FCC certified RM Italy HL150 - 150w - no tuner - manual switching? not FCC certified RM Italy HL300B = 300w - no tuner - manual switching? not FCC cerified Antennas Too many to list Personal favorites - G0GSF- multiband dipole - 4 bands are OK w/o a tuner, EFHW - cut to 45 ft with EARCI matchbox KX3 tuner will match 80-10m Ariel NY4G Sent from my iPad On Jun 30, 2013, at 11:39 PM, KF5TEU bha...@flexbrite.com wrote: While all these posts have good advice for a bc trip , I really just want the KX3 amplifier.

Re: [Elecraft] KX3 Amp
Hmm, reading all this and wondering (wanting) more clarification of what is meant by We are going out over 200 mi. from the nearest real town That would describe 75% or maybe 90% of Alaska. If this is a short-term camping trip or vacation it will be a bit different from living full-time (Off the grid). I know a little bit about both situations (serious backpacker in the Sierras in the 1970's; lived totally off the grid for ten years in near bush Alaska. I did have a dirt road but no electricity, phone, running water, etc. Three years of that I lived in a 8x10 foot wall tent. But I had a 1700w gas generator, 100AH marine battery, HF and 2m radios, battery TV and car stereo. I was 25 air miles (and 90 road miles) from a large city. I used my 2m radio to access a repeater with a phone patch or walked to a neighbor that had telephone. Nearest ambulance service was 50 two-lane mountain road miles away (took 1-hour response time after contact). Fire dept was also that far away. GPS had not been invented, yet. Marine rescue was via VHF channel-21. Loran-C was the standard navigation tool. Today, I would probably consider having both ham radio and an alternative (just in case). What I got would depend if this is a short trip or living full-time. People in bush AK often have satellite internet and TV, and/or sat-phone. The old days in AK HF ham radio was a major communication link (for everything). When living out in the bush one develops good neighbors and a lot of self-sufficiency (and being very careful). I lived alone so no one would likely come looking for a couple weeks or more. This is more so if a backcountry traveler. 73, Ed - KL7UW http://www.kl7uw.com dubus...@gmail.com Kits made by 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
Re: [Elecraft] KX3 Amp
One correction. The HF Packer is not a 50w amp. It's about 45w at 160m, and then steadily less as you go up in frequency (40w for 80m, 35w for 40-20m, 30w for 17/15m, 25w for 12m and about 20w for 10m). It doesn't support 6m. These numbers come directly from a graph in the HF Packer manual. John AC0ZG On 6/30/2013 10:18 PM, Ariel Jacala wrote: Hands down the KXPA100.

Anyway it seems that with 5 W drive and output power of below 200W, HLA 300 Plus can be used on all the bands quite successfully. I have also modified the amp to work from PTT signal only, and disabled RF VOX in it. RF band sensing remained intact. 73, Igor UA9CDC - Original Message - From: Geoffrey Mackenzie-Kennedy lx...@pt.lu To: Igor Sokolov ua9...@gmail.com Cc: Elecraft Discussion List elecraft@mailman.qth.net Sent: Tuesday, March 26, 2013 8:59 PM Subject: Re: [Elecraft] KX3 Amp Hello Igor, If you want to measure (with useful accuracy) the level of the IMD products generated by your KX3 and HLA 300 Plus, all that you would need in addition to your TS590 is a Two Tone (AF) Generator, an AF Spectrum Analyser and your computer.

[Elecraft] KX3 Amp
Hi All, To echo Jim Brown's cautionary statement about IMD with the RM Italy HLA series amps, there is some good info on Tom Rausch's (W8JI) website concerning the HLA-150. That amp will run up to 150 watts or so, but according to some testing that Rausch did, if you go much over 100 watts, the IMD gets pretty marginal! Presumably the HLA-300 have some similar optimal point below it's maximum capability. Apparently this is not at all uncommon, particularly with 12 V. amps. Even the K3 loses some of it's IMD quality if you go over 100 watts, which you can do somewhat.

Re: [Elecraft] KX3 Amp
Guys, I run my KX3 as IF on 2m FM running either 3w for 25w or 5w for 50w out of the 2m amplifier. I have not noticed the KX3 getting overly hot, even though FM is key down continuous carrier. But I would be careful at full power. I can run 270w with 12w input on 20m. With 5w input I get 130w (note the values in the table on the website are overrated due to a measurement error - the K3 outputs 12w and not 15w). This using my CCI model EB27A amplifier rated for 300w with 20w drive. http://www.kl7uw.com/HF-300PA.htm I have found most amps will provide usable though lower output if underdriven. The KXPA100 may be capable of something like 60w with 5w drive? Gain often is a bit higher as lower levels of drive. 73, Ed - KL7UW - Date: Sun, 24 Mar 2013 19:11:33 +1000 From: Gary Gregory vk1zzg...@gmail.com To: Fred Smith m...@mo-net.com Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] KX3 Amp Not sure 11W drive is good for normal rag chewing with the KX3.

Giff, That was fast. The 100 Watter from Elecraft that matches your new toy should be out soon. If you can't wait, Tentec has anew one out that got good review in QST and they said it plays nice with the KX3. However, I'm waiting for Elecraft amp for my KX3. 73 from Fla., Barry K3NDM - Original Message - From: Giff Hammar lt;gham...@sv-phoenix.comgt; To: elecraft@mailman.qth.net Sent: Fri, 22 Mar 2013 12:20:50 - (UTC) Subject: [Elecraft] KX3 Amp I've been having a blast playing with my new KX3 for the past couple of weeks and am now looking forward to adding a 100W amp.

[Elecraft] KX3 Amp
I bought a KX3 a bit over a week ago and have had a blast playing with it. Now it's time to start thinking about an amp. I know the one designed for it is supposed to be out by July, but I was wondering what people are using now and whether or not they would recommend them to others (I know that's a loaded question). 73, Giff / K1GAH __ 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] KX3 Amp
I believe the Elecraft gang are hard at work on the KXPA100 for the KX3 (kinda think it will be ready for Dayton -?). This amp will work with any 5-10w radio, including the K3/10. I build one of the CCI kits; the EB27A which provides 270w on 20m with 12w from either the KX3 or K3. I have used it several times checking into the Elecraft SSB Net. http://www.kl7uw.com/HF-300PA.htm I am starting on the AN762 kit (5w/140w) and will have it at Dayton, if anyone is interested. 73, Ed - KL7UW Date: Fri, 22 Mar 2013 13:35:22 +0100 From: Brian Lodahl OZ2BRN oz2...@post.cybercity.dk To: elecraft@mailman.qth.net Subject: Re: [Elecraft] KX3 Amp Message-ID: 514c500a.1020...@post.cybercity.dk Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi Giff K1GAH, I am in progress of building my own amp according to the Motorola EB-104 application note; www.ab4oj.com/dl/eb104.pdf 5-10W in, about 600W out depending on your DC supply, all-transistor-amp using four MRF-150 power FET's.

Re: [Elecraft] KX3 Amp
I've been using a Tokyo High Power HL-45B and have been satisfied enough with it. It's only 50 watts and it doesn't do automatic band switching with the KX3 but the price point is well below where the Elecraft amp will likely be announced.

Re: [Elecraft] KX3 Amp
I have been using my KX3 for a few months now, and never needed an amp. Nine out of ten times, if I hear someone, they can hear me (CW). Actually, even with my K1 at 6W, I never felt the need. For SSB, I can see how it would help, but for CW, it's a waste of money.

Don sr. --WA2TPU -- Thanks Don, that's amazing! Personally, I'd rather use the money I would use to buy an amp to get more QRP kits. I plan on building a KX1, just for fun (already built a K1 K2), and just secured a Weber MTR which I should receive this week.. A few Watts is indeed enough for CW. I have been tempted to get an amp, but then thinking about it, I realized it wouldn't make much difference. I couldn't take it out camping without having to carry a big battery anyway; not practical. And I would have to change my antenna, power supply and probably a couple other things to accommodate the extra power. Just to warm up the air around. No Thanks. Sometimes I turn my KX3 power down, just out of curiosity, and it has worked down to 100mW! Faint but readable, 830 miles distance. Usually, anything at or above 1W goes through. I had Russia on 5W using my homebrew magnetic loop (21ft perimeter) inside the house! It wasn't even oriented the right way. I think anyone who needs an amp actually needs a better antenna... (I use a PAR End-Fed). So, I'm going to skip the KX3 Amp and get the auto tuner, charger and 2m module..

I tried it today with a cable from KX3 ACC2 to the T/R input on the Juma amp. Yes it did key the amp, but when connected there was an appreciable receive loss on the KX3.

[Elecraft] [KX3 amp] 100/50
Hello Rick, May be a bit off-topic here. I have no idea of how KPA500 sales volume compared with other competitors. My choice of KPA500 is due to its ability of being portable and I don't need full 1kw in my apartment operation condition. My original intention is to get a SPE-1ka expert where is only slightly less than US$4000 here in VR2. I consider SPE-1Ka is very value for money in my prospective (or in terms of $/watt) and also fulfill the ability to be portable. However, I am using hamstick in a high rise apartment so that it is no way to operate full 1kw. Therefore, I drop idea of SPE-1ka. Bearing in mind, the total cost of Elecraft amplifier should be KPA500 + KAT500. For similar reason, I sold my Icom ICPW-1 which was a strong work horse. The sales proceed of my PW1 will be very much enough for me to buy any 500w linear amplifier. The strengthen of JPY does give hard hit to Japanese manufacturer. In terms of US$, street price of ICPW1 has been increased from US$3,900 to US$5,000 solely due to the rise of JPY. Bearing in mind, ICPW1 delivers full 1kw RTTY. Business culture of US and Japanese is different. Both cultures have its own successful history depending on when and where. In the early days of my business school in the universities, Just-in-time (no stock of spare parts) was given high regard. Toyota has been a succesful example of Just-in-time. However, after the tsunami last year, most Japanese manufacturers exactly died on the hands of Just-in-time. Hong Kong is some how a link between western and eastern culture. We are hugely influenced by the British in terms of western ideas and at the same time have our own eastern values. We are lucky enough to learn the good / bad of both cultures. The composition of my radio shack fully reflect this. I have the big ICOMs as station radios. K3 is for portable and QRV to outline islands - the smallest radio with true dual receivers. The forthcoming KX3 will be used as a man pack radio. Lastly, I have a US$30 Chinese H/T for casual use. Under digital mode, NUE-PSK modem is my choice for PSK31. SCS pactor 3 modem is for airmail and winlink.

Re: [Elecraft] [KX3 amp] 100/50
I don't understand. With the K3/KPA500 there is no knob on the KPA500 but if you want to change the power level you just turn the power knob on the K3. The K3 can remember that level the next time you return to that band if you wish. A power knob on the KPA500 would be redundant and superfluous. If the KX3 and its amplifier are set up similarly, and I suspect they will be, then there is no need for the control. And anyway, putting that control on the amp would constrain where you could place the amp in order to use the power control. Does your issue arise because you want to use the amp with something other than a KX3 and that other rig has no easy way to control its output power?

Wayne, I like the idea; albeit for different reasons. I began operating QRP on all my rigs for 4 special reasons My Hamlets - my four children that are all licensed and formed their own club WK1RK. In fact, my youngest son is now studying for an Extra upgrade (and he is 12 and the Net Control for their VOIP net). I never run more than 20w HF or VHF because most of my antennas are close enough that any higher would be problematic. In the Van as well. I would love a switch or jumper on the amp to set a max power. Will the Amp be linear or simply a flat fixed output? If the Later, then a three position switch of 20w, 50w, 100w would be useful as well in the long run. Those are three power settings that actually are steps up. I was not sure about this until I saw the post from JA but agree (even if for different reasons). A switch would be best for me as I could flip the switch based upon whether I have the kids with me or not.

A switch would be best for me as I could flip the switch based upon whether I have the kids with me or not. As the AMP is a but down the road I hope this is something worth considering and is early enough to be considered in the developement.

I believe that will be the only 100w amp for qrp rigs with filtered output so it should be popular with other rigs as well. 73 Mike R Sent from my spy ring Amateur/Ham Radio KE5GBC HF Echolink __ __ 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 __ 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 - Web mail provided by NuNet, Inc.

Re: [Elecraft] [KX3 amp] 100/50
*FW switchable might work better? Would hate to have to run around back of the motorhome to crank the power up...especially if I am moving art the time...could be problematical?

I never run more than 20w HF or VHF because most of my antennas are close enough that any higher would be problematic. In the Van as well. I would love a switch or jumper on the amp to set a max power. Will the Amp be linear or simply a flat fixed output?
