[Elecraft] goodbye
I don't have a K3 and I will not order one until it is a stable product and on-the-shelf for immediate delivery. My homebrew 10 MHz CW transceiver, EA12, IC-735 and K2 are working fine. .. just got my list password, that I didn't chose myself, that's for sure.

Re: [Elecraft] simple iambic paddle
On Thursday 24 April 2008 12:39:01 pm Brian Lloyd wrote: Does anyone have a design for a very simple iambic key that can be made with simple materials and hand tools? I made one when I built The Ultimate Keyer Mk2 by G3RVM in the February 1980 issue of Radio Communication. I used two thin strips of copper clad board. Mine was double sided but singe sided is all that's needed. I sawed a small diecast box to get two nice right angle brackets and screwed them on the base of the main diecast box where I had the electronics. The PCB strips came out the front of the box separated about half an inch. I used stick-on rubber feet as the thumb abd finger contacts. For the switch contacts, I drilled quarter inch staggered holes in the PCBs and using the other two corners of the cut box, mounted them outside the PCBs with a long screw going through each PCB hole. So the mounts for the screws are both outside the strips. The PCB strips were nicely springy and I adjusted the screws to a very fine touch. I bought a Bencher paddle soon afterwards. I have no idea why I dismantled my own paddles; I remember their being just as good as the Bencher.

[Elecraft] my first SMD soldering
Recently I bought a Hakko 936 soldering station and several T-1 fine conical bits. My first SMD soldering is a 28 pin SOIC chip to a PDIP adapter PCB so that I can experiment with a CS8427 in a breadboard. The CS8427 is a digital sound s/pdif AES3 transceiver, which I'm using as a general purpose filter for optical and coaxial digital sound. The 28 pin SOIC is a comfortable size for me to start. I soldered it well, no bridges, using an Optivisor and a T-1 bit. The soldering isn't a work of art but is fully functional. I look forward to building the njqrp.org DDS-60 kit that I've had pending, though the AD9851's legs are a lot smaller and closer set than those of the CS8427. Thankyou Tom for posting the bit numbers with their uses. Ian, G4ICV, AB2GR, K2 #4962 -- ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

It runs on many wireless routers, not only Linksys. The two serial ports are supported as /dev/ttyS0 and /dev/ttyS1. I was disappointed to find that my WRT54G is version 5 and has only half the flash and ram that versions 1 to 4 have, and consequently is minimally supported by OpenWRT. So I replaced it with a WRT54GL, Linksys's acknowledgment that there are tinkerers in the world who want the original flash and ram back, at a higher price of course. There is a serial over Bluetooth standard. All that's needed is Simon's HRD to invent, or use a serial over Wifi and connect our serial enabled radios to a router's serial port. With the router's firmware open source and clever people so minded, operating the radio over the network isn't so distant a dream. Then there's Tentec's Omni VII, an already network enabled transceiver with an Ethernet connection, easily added to a consumer network.

Yes indeed. My Eddystone EA12 receiver that I bought from Tom Roberts, G3YTO (SK 1985) is a dual conversion with a tunable first IF from 1.1 Mc/s to 1.7 Mc/s and crystal controlled converters changing the bands to the tunable IF. The second IF is 100 kc/s with a slot filter and continuously variable selectivity: this is accomplished by varying, mechanically the coupling between the coils - it's like flying by the seat .. rather than by wire. At the narrow end of the filter, a 100 kc/s crystal kicks in and I can feel the switch that does it. With up to volts input to the linear ECC189 to the ECH81 first mixer, I think modern radios are building ever more complex sandcastles rather than pyramids.

Unlike the K2, it was open-loop, but better than the unadjusted IC-735.

[Elecraft] Custom K2?
 Although none of us (AFAIK) are allowed access to the control firmware source, its action is well specified and effectively forms an Application Programming Interface.  It would be possible to put the K2 into a bigger box, remove the front panel and wire up a custom microcontroller to all the buttons, knobs, rotary encoder and LED signal strength meter - the API.  The new controller would interface to a new much larger panel with, e.g., an analogue meter, simulating double key pressings with a single button, such as one marked AGC Off, and many other more convenient features that the K2 can't do because of limited and already crowded panel area, and the necessity to keep the cost to that of a marketable product.  Putting the current rotary encoder on the new panel, it might be possible to add variable speed tuning by having the new controller read the encoder and feed varying speed signals to the K2 encoder interface. Being more adventurous, it might be possible to implement IF shift by simultaneously operating the BFO setting and the tuning encoder. Being extravagant, a full colour display could replace the K2's LCD and one of those great old mechanical dials could be used. A larger speaker, internal power supply, - the K2 could be turned into a large base station with all kinds of new features.  With the K2 control API, the new panel would be largely limited only by the implementor's imagination. If the Elecraft list members colaberated and shared the source code of the new microcontroller, this would open up a new dimension in customizing a K2. I see Andy, N8MX has gone a little way towards such a project: he has separated the display and put the K2 in a mounting on his bike in the first old picture gallery.

Re: [Elecraft] OT: 50 years
I became interested in Amateur Radio, 1975 when a friend showed me his single transistor, FM 'transmitter'. Later I learned it was just an unbuffered Colpitts oscillator, about five turns of copper in the coil and a something picofarad capacitor and the 300 ohm twin aerial as part of the tuned circuit, modulated by a tape deck line output on the base of the BD235 transistor. When I discovered Amateur Radio, the literature of the day said that KA+3 callsigns were American military stationed in Japan. Earning my G4ICV in 1979, I learned quickly that those KA callsigns, most of them, were novices in the 21.1 to 21.2 MHz band. I have 'Worked All States' CW as G4ICV, and probably half of my QSL cards are from novices in that segment - a few of them joyously declaring in CW and on the cards that I was their first DX. What a forlorn band that is now.

An important point about RS-232, COM ports, /dev/cuad0, /dev/ttyS0 .. whatever, is that the serial data timing can be very accurately known: the time taken for a micro to load to the data registers and send the data can be used in real time control. At 115200 bits per second, a byte takes less than 100 microseconds to propagate. Midi is such a real time control and it uses the very modest speed, by today's standard, 31250 bps. USB can't guarantee such timing accuracy for control purposes - witness the mess with USB midi equipment that had 80 milliseconds delay before hearing a sound - fine if a printer doesn't start in that time but completely useless for real time music multitracking. A klutz was required, such as Steinberg's ASIO. Even so, USB still can't compete with a 23 year old standard at 31250 bps for real time midi. There is no USB on my Kurzweil PC2R. Present are midi in, out and thru, analog and 24 bit digital sound out: it's professional equipment.

Re: [Elecraft] Ideas - new Elecraft Products
CW only, optimized, completely analogue, airspaced variable capacitor tuned, quality mechanical reduction (not planetary), mono-band, single conversion, preferably Top Band first, transceiver. I'm working on it myself - bought twelve 15x12 double sided copper clad boards at $4.25 per board for the rest of my lifetime needs. TUF-3 mixers soon, or maybe I should use a 6JH8 beam deflection mixer hybrid like the Practical Wireless 'Epson' in September 1974 by G4AR (SK). The K2 is good, but typically too digital nowadays.

Re: [Elecraft] K2 build - Control board Resistor SIPs not marked right.
On Monday 20 March 2006 15:01, Darwin, Keith wrote: I'm trying very hard to avoid any rework. Rework means I have to take the board to work and I don't want to do that. I believe by being careful I should be able to avoid any rework during the process. We'll see... Keith, I built my K2 in June last year. The most important step in my opinion is to do a full inventory, at the same time partitioning components that look similar to separate marked locations. I used two cheap drawer sets with around a hundred drawers. I marked the drawer number in the inventory pages of the manual for every item. There are many reasons for doing this. Identifying parts is easier, e.g., there may be three capacitors of the same value, and two that are similar looking but different. Identifying them and separating them is easy at this stage when some items can be identified by a process of elimination. An obvious advantage is that missing parts will be discovered and a quick delivery from Elecraft won't hold up progress. My K2 kit did not have the fiber washers used in mounting the output transistors or speaker. Having completed a full inventory in this way, every part has already been identified once and placed so that it can be retrieved with a low chance of fetching the wrong part. On fetching it to solder it in, I checked it a second time. And I made a third check with the soldering iron in my hand. I had one missing hearbeat when the construction notes referred to parts already installed, and I had not installed them. I had this awful fealing of having installed the display or a large IC that would need to be removed to install something I had missed. Luckily it was not critical. My error was that two pages had stuck together and I had skipped two pages. If I build another K2, I will make sure that turning pages results in the correct sequential page number. I'm sure triple checking every component was a key to my not needing to rework anything.

Re: [Elecraft] Simple-minded SPAM filters vs. list participation
On Wednesday 15 March 2006 15:29, Mike Morrow wrote: Please...if you are requesting help, don't insult me by expecting me to jump through these idiotic processes that say, in effect, that your time is more valuable than mine. Mike, You have a 'Reply To' in your postings' headers that directs a reply to your email address rather than the list address, as do many people here. It can be a problem if the responder doesn't notice this, especially if the email address is an autoresponder. I use a white list email filter on my local computer and no 'catch all' mailboxes at my domains. It's much easier to teach filters to recognize good email than try to identify spam. All messages are directed to the spam box and land there unless the filter sees them as good. For elecraft related email, I look for two header lines. If 'X-Original-To' contains [EMAIL PROTECTED], the email goes to my elecraft list box. If not, and [Elecraft] is on the 'To' line, someone has written to me directly and it is directed to my elecraft private reply box. If someone writes to me directly without some key, such as [Elecraft] on the 'To' line, or my name on the 'To' line, (spammers collect only email addresses) it lands in the spam box. I look at everything in the spam box and if I see something good, I add it to the filters. I use more robust methods, filtering on 'Return-Path' or others that are not easily forged, for sites that are frequently forged by scammers and spammers. I won't fill in web forms to contact anyone. I have registered with sites that are free, but only to purchase online. If I have to register to look at a file, even if registering is free, I go without it or look somewhere else.

[Elecraft] power output of K2
I haven't been too happy with the power output of my K2, but I didn't know if my vintage 1979 Heathkit power meter is reading low. Today, I used an oscilloscope and measured 70.4 Volts peak to peak at 1.817 MHz into a 50 ohm dummy load with the meter indicating just under 10 Watts. I trust the calibration of the 'scope more than the meter. That 70.4 Volts peak to peak is 12.4 Watts; my Heathkit meter is reading low.
