Starting in the late 1960s I was one of the FCC code examiners in San Francisco. One day an "old timer" coast station operator came up for the Radiotelegraph First Class code test - 25 wpm - where a "mill" could be used. He said that he wanted "the First" before he retired. He set it up, and just before I started the tape he asked whether it was OK to smoke during the test. In those days, no problem. He put on the "cans" and said "start the tape". He reached into his pocket, took out a cigarette. Then he reached into another pocket, and pulled out a book of matches, lit the cigarette, put the extinguished match in an ashtray, dropped the matchbook on the floor, bent down to pick it up, put it back in his pocket, sat back for a few seconds, and then started typing like a madman about halfway into the 5 minute tape - perfect copy.

Re: [Elecraft] Iambic Keying (WAS: Straight key first?)
For the commercial and military ops, it was all traffic handling and if you did not have a written copy, you didn't copy it. It is pretty hard to head copy a very long message if it is five letter code groups or in a language that you are not fluent. For that matter, it would be pretty hard to head copy and then write a full minute with no errors to pass the FCC code test. Head copy is pretty much a ham radio thing.

Re: [Elecraft] Iambic Keying (WAS: Straight key first?)
The M/G is only slightly lighter (800 lbs) than the TBL (900 lbs) and is located on the main deck cabin just forward of the crew quarters and about75 ft aft of the radio room. The TCE M/G is in the same compartment and only weighs about 150 lbs. I think of these 200 watt and 125 watt behemouths every time someone complains about the light weight of the K3. This refers to the USS Stewart, DE238. The TBL on the Cavalla was removed and replaced with a Collins URC-32 SSB 500 watt transceiver during a Cold War retrofit.

Re: [Elecraft] OT: My "other" hand sending
I used paddles just like I use a bug; with my arm lying on the table and rolling my wrist and hand from side to side. Sort of hard to do that "reaching over the top", Hi! But I learned both a bug and paddles right handed in spite of being a southpaw so it was never an issue. Of course, back when bugs were very common it was considered very bad manners to use someone else's bug. We took our own with us, both commercial and Ham operators. Everyone had a straight key, and most bugs were equipped with a little paddle on the end of its cord that had two flat copper contacts separated by an insulator. You slipped that between the frame and the hot strip going to the contact on the straight key and you were ready to send.

Re: [Elecraft] Iambic Keying (WAS: Straight key first?)
Or you could do what I did: shatter my right wrist in so many places they had to pin it together. For eight weeks I was in a cast that held my hand immobile; thus necessitating my entry into the world of left handedness. I learned to do every thing with my left hand, most especially how to write. Made me ambidextrous in many of the things I do. I could even throw a baseball with my non-dominant hand. Could not throw it fast but I could hit the target. This accident interrupted my entry into amateur radio for many years. The theory was simple but my right hand would not send CW. By the time I thought to try my left hand other interested had taken over. Oh well, it would have been nice to have gotten my ticket in 1966 or so. I was learning how to send on a bug at the same time. The point being I can still write with my left hand if necessary but I have found it simple to send and write with the same hand. There is plenty of time as long as you copy in your head for a few seconds (words). Now to learn how to send left handed to ease the pain in my right wrist. 73, Kevin.

I don't think learning one helps you with the others. Hi I worked in Commercial CW communications at the tail-end of the era in the 50's and early 60's. At one point while in the Arctic we communicated with 2 stations in the south, Winnipeg and Ottawa. Between the 2 stations there would be 8 to 10 different operators. I could tell immediately who was on shift by the sound of the 'fist'. Almost all of the operators used a bug (each carried his in it's own case ... like professional pool players). A new man was immediately recognized ... and the usual response was to speed up hi. Personal communications was frowned upon. However on a night shift there would be a lot of banter ... (you would think we had QSK hi) You had to be careful though .. in those days we actually had Radio Monitoring Stations. It was possible to actually get a ticket for illegal traffic hi hi. The person giving the citation had to be a CW op as well and vy mean. I agree that certain kinds of "swing" with faster dots than dashes makes copying easier. Perfect CW ... as generated by a computer I find becomes harder to copy once the speed goes up beyond 20 WPM. I like an electronic keyer setup to simulate a bug (old habits I guess) with electronic dits and manual dashes. I can use a squeeze type setup ... but find I have to shift to the bug style in order to be more comfortable and to get into the 'swing' of things hi. As far as the straight key I don't know of anyone who continued to use one once they moved out of Radio School. Strange thing though in Radio School all CW reception was recorded with pencil and paper. The really good ops made the transition to the typewriter ... since all messages must be as received ... es not paraphrased hi hi. As mentioned my experience is at the tail end of the era. Some of the old hands (really old hands) talked about how they were sometime forbidden to use a bug as communications was considered to be more accurate with a straight key. Most of these experiences were railroad telegraphers and marine operators . The transmitter we used in the Arctic was a 300 watt Collins with full AM modulation. It was strictly forbidden to use AM. Although I recall using it on a few occasions hi hi. (where did the microphone come from ?) Sorry for rambling on. I was very fortunate to have learned CW and how to type (in a girls class in High School). I don't know one CW op with Alzheimers hi hi It is great for the grey matter. 73 Jim, VE3CI __ 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] Tech Writing - reading the manual
There has been a substantial evolutionary change in documentation and
support in technology, one that has put manuals in a much different
relationship to the user than they had a decade ago.
Some tech products come with no manual (e.g. iPhones). There are big hairy
software extravaganzas that come with no manual (e.g. Photoshop). These
products are not necessarily rejected by users. A manual is one way to get
info to the user, but there are other ways: menu captions, tool tips,
on-line help, context-sensitive help files, and (most importantly) a design
that is laid out so that the user can sometimes guess what to do.
Many products get support through user forums and/or books written by
independent third parties ("VBA Programming for the Total Nitwit"). The K3
enjoys excellent support from both of these sources. When a manufacturer
gets a lot of complaints that people can't understand how to work his
product, he can't hide behind the assertion that his clientele are all
dolts; they probably own other tech products that they can work just fine.
If a program or gadget is hard to understand, it will sell poorly and
acquire a bad reputation; and the converse is true too. The burden is not on
the reader or user. It's on the maker of the product.

[Elecraft] Tech Writing - reading the manual
Hello Joe, Your observation is correct. While many hams blame the manual of whatever radio is poorly written, they in fact simply do not border to read the manual. There is even a test about 'how quick you can operate a radio without reading the manual'. English is not my native language and radio is not my profession. The only way for me to learn radio technology is mostly via reading the manuals thoroughly. Manuals of radio gears are now becoming my toilet readers (excuse for my indecent words!). I have the habit of reading the manuals many times. I ordered the KE7X K3 user guide. No doubt, it is well written and worth the money. However, if one can thoroughly read all the related manuals produced by Elecraft (or even email exchanges in this reflector), he actually doesn't quite need this user guide. I do not have a single intention to damage the sales of the KE7X user guide but just simply express what I feel after reading it.

Re: [Elecraft] Writing
It's not just "tech" writing, but writing in general. I made a (very good) living as a writer (6 books published, many articles in print) since 1977. And, the world has changed so much since then. Plus, it's pervasive. I can't begin to tell you how many CEOs never get past the "executive summary" in a whitepaper. After so many years of working at all levels in the corporate world, I'm convinced that a large number of CEOs have attention deficit disorder (ADD), and I'm serious! The young folks, nowadays, get their news from streaming video media. At some point, reading will become a lost art. Perhaps it already has. I'm 64, working full time, and at last count I read 66 books since a year ago, May. Maybe I'm just old fashioned :-). 73, Rob K6RB __ 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] TX Inhibit options
Roger, Just to be sure before writing you, I tested my K3 by pressing the XMIT key and the K3 goes immediately into Tx-mode but unless there is modulation in SSB/DATA or the CW key is pressed there is no RF output. If I press and hold so that the K3 goes into TUNE then RF is immediately output on 28-MHz. But in no way does my 144-MHz transverter transmit before the INHIBIT line allows it. Transmitting 1.5mw into the transverter without switching the transverter into Tx-mode does no harm and no 144-MHz RF is output. This is using the INHIB function on the K3 being enabled in the proper time by the sequencer that I use. I enable the INHIB function by use of the BAND-0 line (you might come up with a different way) so that INHIB only functions when I am on 144-MHz and above. See: http://www.kl7uw.com/TX-INHIBIT.htm As you can see from the diagram I key the radio with my TX2 relay in my sequencer which defeats the INHIB on the K3 by grounding pin-7 of the ACC jack. You do have to set up for the K3 to be in Inhibit by setting CONFIG: Tx INH to either in HI=Inh or LO=inh. I use HI=Inh. --- Message: 12 Date: Wed, 29 Jun 2011 02:36:29 -0700 (PDT) From: Roger Banks Subject: [Elecraft] TX Inhibit options To: elecraft@mailman.qth.net Message-ID: <1309340189529-6528265.p...@n2.nabble.com> Content-Type: text/plain; charset=us-ascii Hi All. I am using a K3 with internal 144 transverter module. On 2m I use a sequencer for TX/RX as I use a PA and a LNA at the masthead. The rig TX is triggered by the sequencer by using the PTT In line. The sequencer ensures the rig is switched after the LNA. The sequencer is triggered either by a foot switch or by the signalink Data line. The problem I have is that there is a HUGE risk (and I have done it) of inadvertantly using the manual TX button on the front of the K3. If this is done the rig goes to TX and teh sequencer is bypassed - thus blowing the LNA.. ouch. This issue is compounded by the fact that on all other bands I need conventional operation of the ring as there is obviously no problem with sequencers elsewhere and you get used to using eiher ptt or the tx button. Question then - is there a way of disabling/inhibiting the TX button/ mic socket ptt on the rig just on 2m so that on 2m you can only instigate TX via the back panel PTT in line? Help appreciated!

Wayne, congratulations! It did not take you long to find the secret. I still listen to W1AW code practice from time to time and I have only been licensed since 1956. It always pays to listen to well sent code from time to time along with the hodge podge of good and not so good code you hear on the air.

Absolutely Mel.

[Elecraft] TX Inhibit options
I have broken the PTT line in the mike to operate the sequencer input (also have an external toggle switch to operate the sequencer as well.) The sequencer then operates the K3 PTT. This has worked very well on several different IF radios over the years. The K3 PTT line on the front panel mike connector of the K3 is unused. This has worked very well EXCEPT on 6m when I run the amp on SSB. When the mike connector is connected, RF gets back into the K3 and it has a low freq power oscillation. The watt meter looks like a flag waving! If I back off the power on the amp to 100w or less (K3/10 with external PA) I all is fine, so I just run it at reduced power for SSB. On WSJT I run with the mike connector disconnected and all is fine at any power level. (rear panel audio to/from the sound card) This RF feedback issue causes the power to fluctuate at a low freq and is not the typical RF garbage often heard on the bands. The problem comes and goes and I have tried clamp on ferrite beads on EVERYTHING without a good fix. The sequencer/K3 PTT line was originally twisted pair hookup wire, but is now a shielded cable with no change. Perhaps this is a "Pin 1" issue... I am guessing a ground loop of some kind. Goofy non the less. For more info http://www (dot) qth (dot) net/k0awu/K3System.html Good luck and 73 ...

I am using a K3 with internal 144 transverter module. On 2m I use a sequencer for TX/RX as I use a PA and a LNA at the masthead. The rig TX is triggered by the sequencer by using the PTT In line. The sequencer ensures the rig is switched after the LNA. The sequencer is triggered either by a foot switch or by the signalink Data line. The problem I have is that there is a HUGE risk (and I have done it) of inadvertantly using the manual TX button on the front of the K3. If this is done the rig goes to TX and teh sequencer is bypassed - thus blowing the LNA.. ouch. This issue is compounded by the fact that on all other bands I need conventional operation of the ring as there is obviously no problem with sequencers elsewhere and you get used to using eiher ptt or the tx button. Question then - is there a way of disabling/inhibiting the TX button/ mic socket ptt on the rig just on 2m so that on 2m you can only instigate TX via the back panel PTT in line? Help appreciated!

Re: [Elecraft] Iambic Keying (WAS: Straight key first?)
I find this thread a bit strange. There is little doubt in my mind that the best way to send a long message with minimum errors is to send a prepared file by computer with one on the digital modes. Better yet, send it by email over the Internet and skip ham radio all-together. For contesting, pre- prepared messages by F keys is really neat, fast and effective. It is easier to send good code by hand with less practice with an iambic keyer and a decent set of paddles. It can be done with a semi-automatic key (Bug) or a hand key (Straight Key) but it takes a bit more practice and perhaps skill from the operator. My personal selection is usually a Bug or Straight Key, but that implies only that I think it more fun and satisfying, not better. I would also like to make some QSOs with a TBL-6 transmitter and an RBB receiver. They weigh in excess of 2000 pounds more than my K3 and cost 5 or 10 times as much as my K3 without considering 1943 dollars versus 2007 dollars. This does not imply that the TBL-6/RBB is superior to the K3 or that I would like to use them in the next DX contest in lieu of my K3.

To make a "Q" you just hold the dash paddle and tap the dot paddle at any time during the second dash. Press the dash paddle and immediately tap the dot, and you get a "K". And so on. Very simple finger movements. Minimal timing demands on the operator. But it does take a little practice. And some operators aren't interested in doing that. That's fine, but it doesn't mean that Iambic keying isn't a *great* way to produce CW for those who enjoy it.

This would be better than figures for a stand-alone TCXO calibrated in a lab. My add to that would be that an individual K3 could be brought into line on a curve that would be a fourth of the K3's spec. My take is that without dissing someone for WHY they want it, it IS possible and just another aspect of excellence that only lacks firmware to become reality. The TCXO cal interpret firmware would then become a tool which the OWNERS could perfect, and in turn can move into future products, including a utility that takes a precision calibration routine and automatically maxes the frequency stability for a given unit. It could also become a cottage industry for someone who got really good at it to calibrate K3's for temperature stability. Why not? 73, Guy.

[Elecraft] Iambic Keying (WAS: Straight key first?)
I found Iambic keying wonderful to use. I stopped only because it *ruined* my fist for a bug, Hi! To make a "C" you just squeeze both paddles with the dash paddle closing slightly ahead of the dot. To make a "Q" you just hold the dash paddle and tap the dot paddle at any time during the second dash. Press the dash paddle and immediately tap the dot, and you get a "K". And so on. Very simple finger movements. Minimal timing demands on the operator. But it does take a little practice. And some operators aren't interested in doing that. That's fine, but it doesn't mean that Iambic keying isn't a *great* way to produce CW for those who enjoy it.

Presumably this is intended to allow you to have the KPA500 active on some bands, and inactive on others, selected by setting DIGOUT1 (per-band) on the K3.

Re: [Elecraft] Tech Writing
In the early 1960's I was pulled "off the bench" Lockheed Missiles and Space to write a manual and never looked back. I enjoyed 'looking over the shoulders' of engineers and scientists to document what they were doing rather than spending long hours alone designing something myself. The best writing always comes from personal experience so I've taken many important breaks from the keyboard, sometimes for years, to study and actually do the things I write about; field engineering, sales, marketing, management and more (even assembling a radio kit :-). That's made for a fascinating, varied and always challenging career for me. I'm grateful for all those wonderfully competent and creative people out there who don't have the time to write or who don't like to write. You've kept me very, very busy.

This was a 100-watt FD effort, but we ended up substituting the KX3 (at 5-10 W) for one of the "brand X" 100-W radios for most of the weekend.

[Elecraft] (no subject)
I agree. I learned morse with the straight key. One thing I found is that it helps to develop a sense of rhythm. It's like learning to play a musical instrument. I still use a straight key but, I also use paddles. The straight key helps to keep me from getting sloppy which helps to keep me from getting sloppy with the paddles. It also seems to have more energy or personality. I can usually tell when I'm copying computer generated code because, to me, it sounds lifeless. It's like talking with someone that has a monotone voice. I think now there is too much focus on speed and not enough on developing a good fist. As someone mentioned, the keyers in the K2 and K3 are great. But, it still comes down to the operator, in my opinion. The issue isn't "nostalgia" - it's technique and timing. Paddles cover a multitude of sins: as long as you're hitting the paddles somewere close to the right point you'll get nice even CW. With a straight key any technique or timing issues are immediately obvious. The "old timer" WWII radio ops that I've known (in particular my dad) always stressed mastering the straight key before ever trying to use paddles. And if you've heard those OTs on the air, a large percentage of them illustrate the wisdom of learning (and mastering) the straight key first. __ 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] K3 Front Panel Temps/freq drift
Guys, I'm curious what is the max front panel temp you're seeing after a period of operating with significant transmit time? Also what is the room temp at this value. The reason I ask has to do with the K3 Master Oscillator calibration procedure and later drift. A detailed set of measurements with a stock K3 indicates a good correlation of drift with front panel temperature. With the standard oscillator, measurements indicate that the K3 drifts about -1.2 Hz/C (.12ppm/C) degree at 10 MHz. Here a Rb 10MHz secondary frequency standard was used as well as a counter to measure how the audio tone changes vs time. This allows sub Hz changes to be observed. Normally one does the calibration receive only. In that case with an ambient temp of 24C here, the front panel temp rises 34 C after 90 minutes. I normally calibrate after such a warmup. If the front panel temp rises another 10C after periods of transmit, the frequency could be off by about -12 Hz at 10 MHz (-60 Hz at 50 MHz). Sure that's not a lot. But it says, perhaps one shouldn't knock themselves off trying to be super accurate with the calibration. There will be another couple or perhaps as much another 10 Hz (1ppm) error due to transmiter heat buildup. The actual amount can probably never be predicted. It is clear to me if one "needs" more accuracy, the high precision oscillator option and/or locking to an external reference would be needed. I'd love to look at the high stability oscillator drift as well. However, satisfying that curiosity for $100 isn't going to happen. Perhaps someone out there with the high stability oscillator could repeat the above measurements and report the results. 73 de Brian/K3KO - No virus found in this message.

I recall using gum wrappers taped to my fingers when I was a kid ( just fer fun). I still have one hooked up. I don't use it often, but I find difficulty using paddles under QRS conditions. Sadly, so many years of using paddles makes tickling a bug impossible anymore... yuck!

Re: [Elecraft] TX Inhibit options
Roger, You would add your own output that would stay low until the sequencer out for triggering the PTT on the rig is active. This output would also only inhibit the rig when on 2M (a requirement you mentioned), by monitoring the band data outputs of the radio. You would have to build this logic yourself, and add it to your sequencer. (probably not enough time before this weekend's VHF contest...) As I said, it would take some work. But what you are asking for is insurance against operator error. How much does it cost (in time and effort) to rebuild the LNA when you blow it? Or, you could just stay away from that TX button... ;-) 73, Bruce, N1RX > Thanks Bruce. > The sequencer is an SSB DCW2004 B. It does not seem to have a state-change > output from rx to tx.

Re: [Elecraft] TX Inhibit options
Seems to me this -could- be done, but would require some modifications to your sequencer system. Using the TX INH input (pin 7 or AUX connector on the K3, set TX INH to ON). You would need an output from your sequencer that stays low until TX permission is desired. This operation would be dependant on the band the K3 is on, so you would need to add logic to decode the Band0-3 outputs, and set CONFIG:KIO3 to TRN. Alternatively, you could use a KRC2 to access the auxbus data out to decode the TRN band. Again, added logic would activate the inhibit function only when 2M is selected, based on the output of the KRC2. This is all based on reading the signal descriptions in the K3 manual. I have not tried it. I am sure there are probably other ways to accomplish this. Good luck, Bruce, N1RX > Question then - is there a way of disabling/inhibiting the TX button/ mic > socket ptt on the rig just on 2m so that on 2m you can only instigate TX via > the back panel PTT in line? > Help appreciated! > Roger Banks > GW4WND __ 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

In late '09 I read the World of Ideas column in CQ by the late Dave Ingram, K4TWJ, wherein he introduced the W6AME Bushwhacker single lever paddle kit. His statement that many ops find single lever keying easier and more accurate than iambic intrigued me so I ordered one and received it on a snowy Christmas Eve just before our Christmas blizzard of '09 so I had plenty of time to play with it. Admittedly, operating one is deceptively simple yet takes a much different technique than iambic paddles. I find my accuracy has improved but still has a long way to go! http://www.americanmorse.com/bushwhacker.htm It is a well-made unit, very precise, and offers a wide range of adjustment. I've had several straight keys from various no-name cheapies to a J-38. Last August I picked up a tarnished key on a black krinkle finish base. It looked neat and felt good so I paid the asking price and found out later that it is a Nye Speed-X key. I cleaned the nickel parts with NEVR-DULL and it looks great on the desk and is much easier to use than any previous key. I bought the matching base from Morse Express which makes for a nice key that is not too high off the desk top. 73, de Nate N0NB >> -- "The optimist proclaims that we live in the best of all possible worlds.

[Elecraft] KPA3 100 Watt Amp
I've just installed the KPA3 in my K3. The installation went superb and the Transmitter Calibration Gain worked fine. However, I'm able to get 100 watts out on 20 meter through 6 meter but 30, 40, 80, and 160 all come up short. Each measures about 80 watts, via the K3 internal measure under the "Tune" setting into a 50 ohm dummy load. I don't have an external wattmeter to double check. Is this normal operation? If not, any thoughts? I have to say that I'm simply delighted with my K3. Originally purchased in 2008, I've been able to confirm 135 countries at the 5/10 watt level into verticals. Upgraded over those three years with ATU, Roofing Filters, P3, and now the KPA3 --- not to mention several firmware updates. This rig can't be beat! Thanks for any insight you can offer.

This would eliminate the waste of all that power in the dummy load, and provide a cleaner output, as the K3 LPA board (12w amp) is not used, I believe.

Re: [Elecraft] KPA500 AUX Cable Keying (DIGOUT1)
I'd like some confirmation of this. I can see in the KPA500 manual (rev A, page 16) that pin 11 of the AUX connector is INHIBIT#. That's fine. Pin 11 on the K3 AUX connector is DIGOUT1, OK. However, also in the KPA500 manual (page 17), the wiring for a cable between the K3 and the KPA500 does not use pin 11. I have constructed my K3-KPA500 AUX cable according to this table, in anticipation of receiving my KPA500 kit later this summer. If this table is correct, I cannot see how DIGOUT1 affects the KPA500. If in fact, It does inhibit the KPA500 (auto-magically, without being connected), does this mean that DIGOUT1 can no longer be used to control the PR6 preamp, when a KPA500 is connected to a K3? Somewhat confused in NH, Bruce, N1RX > Make sure that DIGOUT1 is turned OFF from the K3. Turning it on disables the KPA. Note that this is a per-band function, so it needs to > be turned off for each band you wish to use the KPA500. > Jack Brindle, W6FB __ 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] Straight key first?
I like the keyer in the K3. Long ago, my straight key was all I had. For a while I used a "bug," but keeping it adjusted was a nuisance. As soon as Heath came out with their keyer, I built one and loved it. My own experience is that it becomes very hard to copy fast CW if the sender is careless about all aspects of sending, including letter and word spaces. LIke Ed, I too learned code from an Instructograph, and it taught me what properly-sent code should sound like. I am perfectly willing for the keyer in the rig to clean up my sending a little, and although I seldom stray much above 25 wpm anymore, I do like the sound of clean CW. Somewhere amongst my souvenirs I have an ARRL 35 wpm certificate, and I used a keyboard for a long time, since my typing speed is in excess of 100 wpm. I liked the keyboard buffer...it was a little like running PSK...load it up and then sit back and relax. Nowdays, my 78-year old body would not send very good CW with a straight key, and I agree with those who pegged the straight key as "nostalgia." For me it is a matter of practicality.
