Re: [Elecraft] [K2] MAB - anyone picking this up?
I'd just noticed the MAB on the LA3ZA modifications page and was doing initial research, although my feeling is that the component sourcing costs are going to be too high to justify, especially if one has to buy the extender and pay customs clearance fees on it as well as multiple lots of international shipping (Mouser is OK if one can bulk up the order with other things that only they can supply, as they have special arrangements to pay UK taxes up front). I don't have the capabilities for cutting up the boards and I'm not sure if I could sell them on anyway (also there may also be consequences of becoming a manufacturer in terms of legal responsibilities). However, I did have a look at the ExpressPCB site and I noted: 1) they advise against cutting up four layer boards because of the risk of shorting power and ground planes. That suggests yields from the separation process could be low. 2) they do do large runs much more cheaply, so creating industry standard CAD files may not be necessary. 3) it is difficult to understand why the setup costs are so high and I wonder why they can't give a discount on re-orders from the same CAD file. -- David Woolley Owner K2 06123 On 27/05/14 19:42, Dave KW4M wrote: Each panel contains three MAB boards. So the cost per MAB board would be $11.98. I used a shear to cut out the individual boards. I believe Tom used a band saw. If there was sufficient demand it would make sense to convert the layout to use industry-standard Gerbers and place a larger order from a regular board house. The cost would then be very low. __ 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] Elecraft's linux utilities - somewhat OT, or maybe not
Sorry, but I'm not the least bit interested in building the starting system for my car or understanding the workings of my car in order to be able to start and drive it. It is a tool not a project for me. Ditto computers. The tool shouldn't get in the way of its use. Look at how many people are struggling with canned operating systems. Imagine saddling hem with LUNIX. Not going to happen. I also suspect the 2% of LUNIX users will shrink with time. I applaud those of you who manage to do anything in LUNIX. I also applaud those who can speak foreign languages. 73 de Brian/K3KO On 5/27/2014 11:32 PM, Doug Person via Elecraft wrote: He didn't know me but I knew him.

I couldn't even tell it to reboot. I had hit the power switch and restart it. Windows, regardless of the version, still has lots and lots of problems. It really is very unstable. It has gotten better, but has a LONG way to go to catch up to OS/X for example - which exemplifies Stable. Apple really does have a higher focus on stability and ease of use than Microsoft. Windows 8 is the biggest disaster Microsoft has ever managed to pull off. Makes Vista look like a success story. Windows 9 is due out the end of next year. Your guess is as good as mine what their plans are. Linux is a work of art produced by thousands of programmers across decades. It belongs to no one and everyone. When I use it, which is often, I feel a sense of pride that we, the elders, the senior of the most senior programmers, as a worldwide movement brought this incredible thing to life. It continues to grow and mature. Its vastly better than it was 10 years ago. Nothing is perfect. Driver problems are just as bad on Windows. If you got a printer to work on Windows - consider yourself lucky. There are now about 5 categories of drivers for Windows. You guess if your printer is supplied with the right driver for your version of Windows. To me linux is easy compared to Windows. I can find everything. There are no hidden databases of configuration information. And I'm not constantly assaulted by programs installing other programs that eventually clog up memory to the point where booting takes 10 minutes. Its my opinion that linux is the OS that every ham should learn and love. Its consistent and compatible with the spirit of ham radio. The do-it-yourself, build-your-own mentality that makes the hobby what it is. Linux is not hard and with a little patience it does everything that's important. Consider that Android is linux and that OS/X, for all its glory, is based on just another open source unix derivative. The unix-based OS base is winning and Windows is losing.

Re: [Elecraft] Elecraft's linux utilities - somewhat OT, or maybe not
Since you followed up to my post, Bill, I will clarify that I was only speaking from the developer's perspective on simple for compiling on the common 64 bit AMD/Intel platform and i386 (i486, i586, i686) platform. That said, the two pieces of software I develop do not rely on the differences between the 32 and 64 bit architectures and therefore are an easy recompile. Unless someone wishes to step up as a beta tester for either project, I do not expect people to be compiling their packages even though I put a lot of work into cleaning up Hamlib's build system a couple of years ago and it about as easy as it could get. For that the distributions provide their own package managers that will install precompiled software and take care to assure that all dependencies are correctly installed and managed. There is very little DLL hell on a supported Linux distribution as shared library dependencies are carefully managed, at least on Debian and its derivatives (Ubuntu, Mepis, Siduction, etc.). Things like USB-serial devices are a pain as they are not consistently named across system restarts and some under-the-hood work is necessary to overcome that and a persistent port name can be presented to user software on Linux systems. I've had Windows do the same thing by naming an adapter COM5 one time and COM8 the next and something else some other time so that complaint is a wash. OTOH, the Linux kernel includes drivers for both Prolific and FTDI devices which are very stable for each chipset, so it's a matter of plugging the USB-serial adapter in, figuring out the port name, and away you go. No searching for drivers of questionable quality in the dark corners of the Web for some knock-off adapter. Recall also that while most will agree the K3 is a high performance radio, there are enough complaints about the UI that some that would be interested stay away and buy competing products. Some hold their nose and put up with the K3's UI because of the performance, and still others have no issue with the UI and simply use it as they've learned (I fall in the last camp). In many respects Linux UIs share the same response. Modern systems are complex and perceived user simplicity is a result of someone else dealing with the complexity beforehand and elsewhere. 73, Nate N0NB -- The optimist proclaims that we live in the best of all possible worlds.

Re: [Elecraft] Problems with erratic USB/serial connection
Hi all! After seeing all the potential issues with various USB-to-SERIAL converters i decided to go a different route: picked up this Gearmo 4-port dongle on Amazon for $48. It uses an FTDI chipset and a single USB port gives me 4 DB9 RS232 ports. It also seems to keep the COM port numbering constant. Oh, and i'm using it on my MacBook Pro, running Windows 7 (32bit) in Parallels. Works famously so far (been a few months now). Hooked it up via the LP-Bridge program, and now i can turn the radio off (K3) without HRD crashing. I'm only using 2 COM ports right now: one for the LP-Bridge/K3 and another for this ERC rotor ad--on card that i just assembled last weekend. Brought my ancient CDE HAM IV control box into the 21st century. Anyways, this Gearmo dongle seems like a really good alternative for Macs and PCs that don't have native RS232 ports.

Re: [Elecraft] Problems with erratic USB/serial connection
Stan Nice find. The 4 porter is the way to go for that price. I've used those, moxa's and lantronix devices for as well. Nothing Prolific anymore. For my remote base, I have a $100 used 4 port Lantronix serial over ip device that has been rock solid for 3 years now. Even though it is in the same building, the ability to not have serial issues on a remote base is so key. As you found out, you can search on Amazon (both US and Canada) for FTDI and find a number of great devices. StarTech is another good vender.

Re: [Elecraft] [K2] MAB - anyone picking this up?
The project is at that awkward point where more than a few prototypes are desired but likely not enough to enable a reasonably priced production run. Ideally someone with resources beyond mine would want to pick it up at some point if the numbers are there to justify it. ExpressPCB's advice against cutting four layer boards was noted and considered. To reduce the possibility of shorts, the internal plane layers were designed to have voids in the areas where cuts are to be made. In my estimation, electrical shorts due to cutting the boards is not an issue. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-MAB-anyone-picking-this-up-tp7589489p7589611.html Sent from the Elecraft mailing list archive at 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] Learning Morse Code [OT]
Here are some of my resources I used for learning starting in January of 2014. A lot of it was already mentioned. First note: Spend 25% of your time practicing sending code. It helps you associate sound sequences with characters. Code oscillators are good for this. You can also use your rig in test mode to practice. CW_player and FLDigi can decode CW from a a PC mic. Second note: practice every day for at least 20 minutes, don't skip days. Third note: get on the air as soon as you can. Even if you cannot copy perfectly. Send QRS or AGN or ? if you didn't get something. My preferred software was cw_player to get started and FLDigi once I was primarily playing text files. Here are some good tips:http://www.skccgroup.com/member_services/beginners_corner/ skccgroup is an excelent resource. --- Getting started: (random characters and text players) CW Player: http://www.f6dqm.fr/software.htm Just Learn Morse Codehttp://www.justlearnmorsecode.com/ g4fon Koch trainer:http://www.g4fon.net/CW%20Trainer.htm Learn CW Online:http://lcwo.net/ FLDigi is harder to set up, but probably the cleanest CW sender of text:(most of the other software will send CW from text files also)http://www.w1hkj.com/download.html --- Additional resources: Text files for a player: (this has character groups and words for those groups - get the zipped collection file)http://nfarl.org/sigCW/cwIntro.html Morse code podcast at 5WPM:http://aa9pw.com/category/morse-code/podcast-morse-code/He also has some good online resources:http://aa9pw.com/morsecode/ Nice collection of text to put into one of the CW players:http://www.k7qo.net/answers.zip He also has MP3 files but I preferred to play the files through a player at the speed I wanted.http://www.k7qo.net/ ARRL has on air code and MP3 files: (BTW: ARRL uses FLDigi to send their code)You can also get the answer file and send it through your preferred cw player at the speed you want)http://www.arrl.org/code-transmissionshttp://www.arrl.org/code-practice-files Longer texts for players, it also has MP3's that slowly increase in speed:http://www.skccgroup.com/member_services/learning_center/ After you get to about 5-7wpm you can use Morse runner (10wpm minimum) to practice copying call signs in a simulated contest:http://www.dxatlas.com/morserunner/ Another speed trainer I haven't used yet is:http://www.rufzxp.net/ Hope that helps. 73 - Tom - wa4ta __ 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

[Elecraft] K3 Resistance Checks
OK, I'm at the point where I've completed the construction prior to the initial power on and have a little question on the resistance between U12 and ground. My value is 3.5k ohm. The manual states that some K3s may be only slightly greater than 500 ohms implying that I might expect a value in that area. Clearly 3.5k is much greater. Am I good to go or is my value incorrect? Thanks! 73 de John, 9H5G __ 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

[Elecraft] Computers in the Stone Age
One of the interesting pieces of that history, from a retail consumer user's (layman's) point of view, is that the Apple II (I owned a II+ in the late 1970s) used MS-DOS as its operating system before Apple developed its own. As I recall, the OS was not resident in the early hardware - to use it you first loaded DOS in through a 5 floppy, then used another 5 floppy for data. (My memory is imperfect, but I believe that was correct.) The original IBM PC also had 5 floppy drives. One was for the App (such as WordStar) and the other for the data files. The 3 disk was a much later development, and a great leap forward. The IBM PC, which I bought in 1982 plus or minus a couple of years, cost me $5,000 in the dollars of the day. The most significant development, which some folks today don't remember or never knew, is that e-mail and the Internet began as separate systems. E-mail used ordinary phone lines in its earliest days. I remember well sitting in airport boarding lounges with a set of alligator clips and a screwdriver which I used to remove the cap from the modular telephone jacks so I could dial up other members of our e-mail network. I don't recall the year, but I do remember that when e-mail was merged with the Internet the whole world changed. The idea of controlling my radio equipment with my computer in the 70s never occurred to me . . . . Do I have that history right?

Re: [Elecraft] Computers in the Stone Age
Computers in the Stone Age: I wonder what Fred Flintstone's computer looked like? :=) The IBM PC, which I bought in 1982 plus or minus a couple of years, cost me $5,000 in the dollars of the day. It's interesting that the latest, greatest, bleeding-edge PC always seems to cost about $4000-$5000. Then a year later you can buy the same thing for $1000. And a couple years after that it goes on the scrap heap because it no longer has enough memory / hard disc space / processor speed to run current software.

As I recall, the OS was not resident in the early hardware - to use it you first loaded DOS in through a 5 floppy, then used another 5 floppy for data. (My memory is imperfect, but I believe that was correct.) The original IBM PC also had 5 floppy drives. One was for the App (such as WordStar) and the other for the data files. The 3 disk was a much later development, and a great leap forward. The IBM PC, which I bought in 1982 plus or minus a couple of years, cost me $5,000 in the dollars of the day. The most significant development, which some folks today don't remember or never knew, is that e-mail and the Internet began as separate systems. E-mail used ordinary phone lines in its earliest days. I remember well sitting in airport boarding lounges with a set of alligator clips and a screwdriver which I used to remove the cap from the modular telephone jacks so I could dial up other members of our e-mail network. I don't recall the year, but I do remember that when e-mail was merged with the Internet the whole world changed. The idea of controlling my radio equipment with my computer in the 70s never occurred to me . . . . Do I have that history right?

Re: [Elecraft] Computers in the Stone Age
My first computer was a Sol-20 (1977), with an 8080 and 16K of RAM. There was a skeletal OS in ROM, but you could load a bigger OS and/or Basic from cassette. Later, I got floppy drives and North Star Basic, and still later 8 floppies and the CP/M OS. I wrote a machine-language driver to relocate North Star Basic and link it to CP/M -- the state of the art for a couple of months. I also made some hardware I/O gadgets with spring lever-switches, and a space battle game to go with them. When you hit your target, it rang the bell on the printer. The power of that machine was way, way less than what's in a dishwasher now.

[Elecraft] KX3 Travel Power Supply
I got a Sola SCP30 S12B-DN power supply on Ebay bid $24 on $30 ask and won it with free shipping. I cut off an extension cord and wired that into the AC and put a pigtail with powerpoles and in-line fuse on the DC side. Gives out 11.85V (rated 12V/2.5A). Hooked it up to the KX3 and I could get 10W out with voltage dropping to no lower than 11.5V. Best thing is that it seems to be very quiet, no difference between shack PS, shack battery backup, or KX3 internal batteries watching the S meter on HDSDR. I had hoped that I could adjust the output to be able to charge the internal batteries, but it seems to be potted and sealed. Nice unit, made in Germany, weighs a bit over ½ lb. 73, Keith, N4KDJ __ 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] Computers in the Stone Age
Ted I would argue e-mail and the Internet still are and always have been separate systems. One is a network and the other an application. It is well known that e-mail systems were around a long time before the Internet became common. There was a system called Fidonet that used all kinds of networks including satellite and packet radio as well as dial up for linking. I think most will agree that UNIX with native networking and e-mail apps really enabled the Internet and e-mail as we know it today. Add a browser app and you had the web. 73, Fred, AE6QL The most significant development, which some folks today don't remember or never knew, is that e-mail and the Internet began as separate systems.

Bill, In a similar way, I'm often asked why I spend so much effort with radio equipment, antennas, sunspots, etc. in such a cellphone and Internet dominated world. The reasons are many. None are simple to explain. I started dabbling with Linux 20 years ago because it gave me the opportunity to run the equivalent of Unix on low-cost, non-proprietary hardware (a PC) that I already had in my possession. I had previous experience with Unix, recognized it as a very serious and powerful OS, and wanted to learn more about it. At the same time, I saw Microsoft products as being very poor in quality and being targeted toward individuals who knew very little about computers and (even worse) didn't want to know anything about computers. I wasn't one of those people. Slackware was my Linux distribution of choice in 1994, and it still remains so today. I find many of the flashy all singing / all dancing Linux distributions difficult to use when doing anything out of the ordinary because they often try to think for the user (in their effort to make things easy), and more often than not, get things wrong in the process. To me, these distributions aim for a Microsoft-like audience (individuals who know very little about computers and want to stay that way). Having computer experience that dates back to the late 1970s, maybe you find yourself in a similar situation for a similar set of reasons. I also think that the growing do-it-yourself, build-your-own (Linux) mentality that Doug (K0DXV) pointed out is also what Elecraft is all about as well, so it should come as no surprise that many Linux fans are Elecraft fans, too. 73, de John, KD2BD -- Visit John on the Web at: http://www.qsl.net/kd2bd/ __ 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

In the intervening years I had spent some time tuning the hand bands and would listen a while to some morse code that felt comfortable to me or that was just on the upper edge of my ability to copy. When it came time to work on the code to get my ticket I found I was able to copy code above 10wpm. The casual listening to code helped me get better even though I never once sat down and said I'm going to practice listening to code. Regular practice listening will help but don't underestimate the value of just listening at times. Tune in to some morse and listen to it will doing some other chores around the house. You will be more relaxed when you aren't forcing yourself to sit and actively practice. Another way to get better at faster code is to listen to code during contests and try and pick out what you can of the call signs. Contest code is usually very fast and it really forces you to focus on the sound of code and not count dits and dahs. -- Cheers!

Re: [Elecraft] Computers in the Stone Age
Don't forget how revolutionary the Commodore VIC-20 was with all of 3.2 K of RAM. We (Microlog) made a plug in called the AIR-1 for the VIC that allowed CW RTTY communications. I wrote a complete production test program in BASIC that required no other test equipment but plugging in the AIR-1 and running the tape loaded test program. It checked the CW copy, aligned the AFSK generator and verified CW PTT keying, all in that 3.2 K of RAM with neat graphic indicators on the screen for the production testers. Needless to say I REALLY got fancy when I had all of that extra memory to play with on the later C-64. It was not the full 64K but LOTS more than the VIC. 73, Charlie k3ICH - Original Message - From: Kevin Cozens ke...@ve3syb.ca To: elecraft@mailman.qth.net Sent: Wednesday, May 28, 2014 2:19 PM Subject: Re: [Elecraft] Computers in the Stone Age Someone wrote: Desktop computers did not come into being until the advent of the IBM PC in the 1980s.

[Elecraft] OT: Learning the code
OK.. maybe not too far off-topic... since Elecraft rigs are very much CW oriented. But to those who get concerned or intimidated about learning the code... it's just not that hard. Different, but it can be done at -any- age. Youth only has an advantage in the respect that -everything- is new. Seniority has the benefit of knowing that you - can- do it, but it will take some practice. There are many on-line resources, but the key is to simply listen to the sounds of the characters. And start with a short list. Do the Dit letter characters... E I S H ... then the Dahs: T M O.. and you have the basis of a lot of common words: IT IS THE TIME TO TEST... for example, just with 7 characters. Maybe you can add 5 and 0 (zero).. Another school of thought is to do the lesser used characters first: Z, J, Q... but I don't think it matters. And then add one new character each day. If you have the ability to learn a new word in your spoken vocabulary, then you certainly have the ability to learn morse code. It's really not any more complex. Every spoken word has a beginning, and an end, and when you hear it spoken, you have to wait until the word is finished before you understand fully what the word is. Your brain buffers the incoming sound, and then when you decode the sounds, then instantly, you know the word. Sure, context and experience help you decode things more quickly. It is exactly the same with a morse character. And the more you use it (practice), the easier it becomes. 73 de Ray K2ULR __ 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] OT: Learning the code
I'd recommend starting at a character speed that doesn't sound slow enough to easily count the dits and dahs. For me that was 25wpm or a bit faster. Then it sounds like a pattern rather than separate dits and dahs. Then space the characters far enough apart to give you a fighting chance at recognition but not so far as to be able to repeat the character mentally in your head. It is a bit frustrating at times but you will make progress faster this way. It's basically Farnsworth but made intentionally too fast to count. Use the random characters rather than the dit characters. Practice often. 73 Jim ab3cv On Wed, May 28, 2014 at 4:30 PM, Josh Fiden j...@voodoolab.com wrote: I would advise against ordering it this way. That's how I learned when studying for the novice exam.

Re: [Elecraft] Computers in the Stone Age
Besides the relay-based Mark 1, the first electronic computer I programmed was a Univac 1. Its memory consisted of 100 10-foot long acoustic delay lines, each capable of storing 10 characters - don't remember what the encoding was. You could walk into the main frame. Electronics was vacuum tubes. The tape drives used strings and pulleys to tension the tape. Later IBM drives used vacuum lines, very sophisticated. All these drives would skip blocks of data, so you had to store sequence numbers with the data so you could check that a block was not dropped. The IBM 650 had drum storage - no RAM. The programmer had to know at which arc of rotation the drum was to optimize the code. The first removable cartridge disk drives had 7 megabyte capacity. We tried to use something called an IBM Datacell - RCA had a similar called Race - with cut pieces of tape stored in cans. 400 megabytes of storage, but it was never put in production. We have it nice now! Just put 256 gig of DDS memory in an Intel NUC. Very nice indeed.

Re: [Elecraft] Computers in the Stone Age
Gates and Allen actually did write that software. After seeing what the pair had written in their dorm room, Dr Roberts invited them down to the MITS facility in New Mexico to improve the software for his product. They did so, then eventually moved back up to home - Bellevue, WA to continue the effort. This same software was ported to the favorite processors (mainly Z80, 8080 and 6502, although there may have been a 6800 version) and showed up in many systems, including the Apple, TRS-80, OSI C1P (still have mine) and many others. My first recollection of the Microsoft name comes from a Dr Dobbs article back in 1975 or 76. Microsoft purchased the beginnings of MS-DOS from Seattle Softworks for the IBM effort. My first computer? A home-brew 6502 system started in late 1976, proposed as an article for QST, but not accepted. We had to sneak computer product reviews into QST at that time since the prevailing attitude was that they had little to do with ham radio (reference my review of the Processor Technology VDM-1 in March 1977 QST, among others). That attitude changed within a year. My 6502 system saw its first attempt at contest logging in ARRL November SS 1977, but a severe RFI problem caused the effort to be abandoned. Boy have things come a long way since.

Re: [Elecraft] OT: Learning the code
NO ! Start with the long characters FIRST. We (at Microlog) developed an automatic Morse Trainer for ( an unnamed guvmint agency ) where we simply automated their technique. The first four characters they taught, if my memory is correct, were L, P, Q C. The last ones to learn on the list were E, I, T, M The logic is such that when first learning the code, if you hear a figure 1, you will change your mind four times.is it E, A, W, J, or finally the figure 1. This method teaches you to learn the sound of each character rather than what it looks like printed as dots dashes. Proof of the pudding.my son passed his Novice code test after just two weeks of 20 min per night starting from scratch (NO Morse ability at all to start.). And yes, the characters were send at 15 WPM rate with enough space to equal 5 WPM. Curiously, when asked to send, he would snap out the letters at around 12 to 15 WPM on a hand key because that's how he heard them. 73, Charlie k3ICH __ 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

He asked what it was; I told him; he asked if I had any more Tequila. I said, Yes, why? He said: Then you don't have a problem. Just make another drink.

Re: [Elecraft] Computers in the Stone Age
No your history is not correct. The apple II was available by at least '78 using apple DOS. A few years later MSDOS was created out of desperation by MS when IBM ( for the upcoming IBM PC) wouldn't buy their languages ( MS' only product) unless it came with an operating system, something MS didn't produce. Gates wad able to buy a barely legal clone of CP/M, the most popular op system at the time, and they produced it for IBM as PCDOS. They then marketed it for themselves as MSDOS.

As I recall, the OS was not resident in the early hardware - to use it you first loaded DOS in through a 5 floppy, then used another 5 floppy for data. (My memory is imperfect, but I believe that was correct.) The original IBM PC also had 5 floppy drives. One was for the App (such as WordStar) and the other for the data files. The 3 disk was a much later development, and a great leap forward. The IBM PC, which I bought in 1982 plus or minus a couple of years, cost me $5,000 in the dollars of the day. The most significant development, which some folks today don't remember or never knew, is that e-mail and the Internet began as separate systems. E-mail used ordinary phone lines in its earliest days. I remember well sitting in airport boarding lounges with a set of alligator clips and a screwdriver which I used to remove the cap from the modular telephone jacks so I could dial up other members of our e-mail network. I don't recall the year, but I do remember that when e-mail was merged with the Internet the whole world changed. The idea of controlling my radio equipment with my computer in the 70s never occurred to me . . . . Do I have that history right?

As the owner of a consulting firm that placed some Apple IIs doing some difficult, at that time, interfacing to main frames we welcomed the appearance of the IBM PC when it came on the scene. We had the second IBM PC in Birmingham and after a couple of days of evaluation recompiled our software and the rest was history. 73s Jim, W4ATK On 5/27/2014 9:31 PM, Don Wilhelm wrote: And those computers Tom Watson was speaking of took a large controlled environment room just for the various pieces. It was certainly not a desktop computer. Desktop computers did not come into being until the advent of the IBM PC in the 1980s. I bought my daughter a new IBM PC with 2 floppy drives and 64k of ram for her to use in her college classes. It was later upgraded with a 5 MB hard drive which replaced one of the floppy drives (3.5 inch floppys). We have come a long way since that time. That system cost $2500 at the time, now I can buy a computer with a LOT more capability for less than $300. 73, Don W3FPR On 5/27/2014 9:43 PM, Fred Jensen wrote: At sometime in the 50's, the President of IBM is alleged to have said, The worldwide market for computers is probably about twelve.

Re: [Elecraft] OT: Learning the code
On 5/28/2014 3:03 PM, Ray Sills, K2ULR, wrote: snip If you have the ability to learn a new word in your spoken vocabulary, then you certainly have the ability to learn morse code. It's really not any more complex. Every spoken word has a beginning, and an end, and when you hear it spoken, you have to wait until the word is finished before you understand fully what the word is. Your brain buffers the incoming sound, and then when you decode the sounds, then instantly, you know the word. Sure, context and experience help you decode things more quickly. It is exactly the same with a morse character. And the more you use it (practice), the easier it becomes. Ray has this exactly correct and this fits perfectly with my earlier comment about actually getting on the air and making some QSOs. Becoming proficient at Morse is very much like learning a second language. You can buy all of the learning aids like Rosetta Stone and you will learn the basics. But to become proficient in a second language nothing beats having an actual conversation. Morse is no different; having actual QSOs or conversations teaches you the nuances and you become comfortable with mistakes and errors in sending and receiving. Just like an actual conversation. I have a friend who is proficient in many languages. He actually spent a summer in Holland because he wanted to learn Dutch. He was able to become conversant in a couple of weeks. Once you have the basic letter sounds down, put away the microphone and for yourself to make a certain number of QSOs each day. Also, don't focus too much on what speed you send and receive. Speed will increase with proficiency. That's why the CW Ops Morse Academy is so successful.

Re: [Elecraft] Computers in the Stone Age
Finally, some sanity in this thread! I had colorFORTH on a TRS-80 Color Computer (chiclets keyboard). Wrote a RTTY send/receive program during evenings in the hotel over a 3 day weekend exhibiting at a motorcycle show in Cincinnati as a way to learn FORTH.
