Re: [Elecraft] K3 keying AFSK?
Can you decode RTTY signals? If not, get that working as a first step. Is the soundcard device selected in HRD the same one that is connected to the K3 Line-In and Line Out jacks? The soundcard LINE OUT (or SPKR) should connect to the K3 LINE IN. Do you have the computer soundcard output level sliders set to 75% or greater? Set the MIC SEL in the K3 menu to LINEIN. Adjust the K3 "MIC LEVEL" (actually the Line-in level) so you have 4 bars solid with the 5th bar flashing on the ALC meter. Turn on VOX and it should transmit. 73, Don W3FPR On 6/19/2016 10:00 PM, Richard Vincent wrote: I recently purchased a new to me K3 which I am in the learning curve.

Re: [Elecraft] K3 keying AFSK?
Richard, What do you have set as the keying method in DM-780? I use it extensively and have never had an issue. I believe I have it set to use HRD keying, which does not require the use of vox for keying. Hope this helps. 73 de, Ian, KM4IK On Jun 19, 2016 10:02 PM, "Richard Vincent" wrote: > I recently purchased a new to me K3 which I am in the learning curve.

Re: [Elecraft] K3 Keying external Amps
Hi Richard, If both amplifiers use transistor switching, you may be able to simply connect the two in parallel and use the K3 to activate whatever amp is turned on. I am sure there must be better ways to do it, but simple often has a lot going for it.I have the key out of my K3 connected to a TE SYSTEMS 0552G amp for 6m and a Mierage B1016 amp for 2m.

Re: [Elecraft] K3 keying the KPA-500 & transverter
Hi Toby, if my memory serves me right (digged into the schematics about 7-8 month' ago when I had a problem with one of the key-out jacks) this will never work as both key-out pins share the same circuitry. It's just different "final" switching transistors (and thus different loads possible) that distinguish both. A solution around this could be the band specific PTT solution of WW2R/G4FRE (http://g4fre.com/K3_PTT_sw.htm) or something similar. The key is to use DIGOUT0 or DIGOUT1 to control external switching. It can be configured per band. 73 & gl, Olli - DH8BQA - Original Message - From: To: Sent: Monday, April 11, 2011 10:33 AM Subject: [Elecraft] K3 keying the KPA-500 & transverter > Hi, > > I plan on using my K3 with the KPA-500 and my Kuhne 144 MHz transverter. > > I would like to use the ACC (pin 10) Key-Out for the KPA-500 and the > RCA/Phono Key-Out jack for the transverter.

Re: [Elecraft] K3 keying an amplifier
Or a composite video A/B switch. I have been using a Radio Shack composite/S-Video one in two out Stereo audio and video switch to delegate amplifier key lines, footswitch and Paddles between my primary K3 and my secondary TS570 for a few years now. The S-Video lines switch the paddles between each radio's Microkeyer, while the video and audio RCA cables switch the footswitch send to the Microkeyers and the key lines from the rigs to the amplifier. Snazzy thing, a sloping front panel in silver and gray plastic with big rectangular hard to miss delegation buttons that came with custom labels. I even have a spare set of RCA jacks that might be pressed into service for something else, like big fat red "this radio is enabled" LED lamps... Well, maybe not :) Cost a total of I think $4.

Re: [Elecraft] K3 keying an amplifier
>I don't think the diode isolation will work in this case. > > Scott K9MA If the Icom used an amp key line from an NPN transistor with an open collector and a high value (e.g., 10K) pull-up resistor to a positive supply rail, then all one needs is a steering diode added to the Icom key line configured with the cathode to the junction of the Icom's collector and pull-up resistor. The diode's anode points to the Alpha 9500. The K3 with its MOSFET output simply parallels the 9500 key line. It doesn't care. If the Icom is unpowered or powered, a Schottky steering diode will isolate the pull-up resistor while still allowing the driving transistor's junction to pull low enough to ground. An unbiased or unpowered NPN open-collector switching transistor should not pull to ground potential if the rig is powered down. The only remaining obstacle is that when the Icom is powered down, the Alpha 9500 key line would see 10K resistance through the pull-up resistor to the power supply positive rail. Powered down, that rail may be close to ground potential. So, whether a steering diode alone will work is really a matter of: (1) the value of the pull-up resistor; and (2) whether the Alpha 9500's key line circuitry is sensitive to high-impedance switching. No problem if the Alpha uses a photo-transistor on the input key line, for example. But if say a pair of both pull-up and pull-down resistors are used ahead of a CMOS gate, then the value of the resistors need to be known. If a steering diode still doesn't work, then a separate switching transistor can be used, using an open-collector without a pull-up resistor -- or a MOSFET without a pull up on the drain.

Re: [Elecraft] K3 keying an amplifier
Fred, I run a Kenwood TS-590S and the K3 with my Tokyo Hy Power HL-1.2Kfx amp. I take the keying and ALC lines from both rigs and connect them to an LDG ALK-2 switch (2 port switch) and then connect a set of "common" keying and ALC lines from the LDG to the amp.

In that case, a Schottky steering diode can be used on the Icom key line. A 1N914 or 1N400X series may be fine but I've seen instances where the higher diode junction voltage prevents the line from going low enough to circuit ground potential. Not sure how sensitive the Alpha 9500 is to that effect. I agree with Scott that the K3 should be fine with its open-drain on the MOSFET switch. I don't see this issue very often on the amp key line -- I do see it often when trying to use a single CW keyer, feeding multiple transceiver's in parallel, due to the use of pull-up resistors on the paddle key line. Again, Schottky steering diodes used for isolation at the input to each transceiver's CW key line solves the problem.

Re: [Elecraft] K3 keying an amplifier
You might have a problem when only one rig is powered up, with the unpowered one pulling down the key/control line. The K3 is OK, as both outputs are open drain/collector.

Re: [Elecraft] K3 keying at turn-on
Ken, This sounds like your K3 is configured for DTR keying. Go to the CONFIG menu and look for the PTT-KEY parameter. If it is set for DTR keying, then when the computer boots, its BIOS raises the DTR line a few times which keys the radio. Unless you are normally keying your radio this way, you should set the menu parameter to OFF OFF. I find it easier to turn it off between contests than to remember to go into test mode or unplug the cable every time I boot the computer.

Re: [Elecraft] K3 keying at turn-on
<> That's probably because no one ever said there was an RF pulse. :-) It just pulls the TX line that runs out to the amplifier low.

<< It is not normal behavior for my K3. The red tx light comes on for a split second but there is no amp keying or RF output. 73 Art>> Art, Mine has always closed the amplifier relay control line upon power up during the period after the power switch is pushed "on" and the display illuminates. The K3's red TX light is **not** on during that time. it does it any mode, and any VOX or PTT setting. Make sure yours doesn't do the same thing. I think this would mainly be a problem if someone power the amp and radio up at the same time, or powers the amp slightly before the radio is turned on. While my amps are immune to step-start damage, some systems can be damaged if the relay line is pulled low during the amplifier's power-up step-start sequence. This damage is a step-start design shortfall aggravated by an unusual power up behavior. It's more annoying to me, since it can't damage the amps I have, but it does make me look carefully at meters to be sure it isn't transmitting.

If this is an issue at your station, locate the CONFIG:CW WGHT menu entry and tap '4', changing VOX NOR to AUTO OFF. This will make CW VOX default to OFF when the K3 is turned on.

The problem is, when the radio boots up, the amplifier relay control line is pulled low during the very early part of the power up. This happens in any mode with any VOX setting. The situation this creates is if an external power amp with step-start is connected, some amplifiers go into quiescent current (TX relay closure) when the radio is powering up. This false triggering of the PA relay can cause an amplifier inrush circuit to be damaged. For example the Drake L4B would would try to draw about 500 additional watts through the step-start if the TX line was held low on amplifier power up if the radio is booting at the same time. Seeing all my TX indicators illuminate and hearing relays click when I power up the K3 is more of an annoyance to me, because my amplifers are designed to be in any keying state on power up without damage. On some amplifiers though, it can actually hurt components if they are held in TX mode while powering up. I think the burden of design fault is in the amplifier, there should be no relay line state that causes or allows damage on power up, but the radio boot behavior is a little annoying. It might be some I/O areas like the relay control just fault into a TX mode before the system is booted, and there may be no way around that. 73 Tom __ 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] K3 keying
Barry, Shortening of characters in QSK is a common issue in many transceivers though it seems less of a problem in the K3. What you should really use to combat it is 'Keying Compensation' which you will see in for example Winkey configuration settings and other external keyers; it lengthens each character by a fixed amount (x millisecs) and is independent of keying speed and is designed specifically for this problem. Think I'm right in saying the K3 internal keyer doesn't have this adjustment (yet?). When I checked my K3 on my 'scope the shortening in qsk looked pretty minimal but I find a setting of 3ms makes the (Winkey) keying feel 'sweeter' so that's what I use... 73 and look out for you this weekend at GW0GEI (M2) Stewart Rolfe, GW0ETF Barry Simpson wrote: > > No one has commented on the apparent shortening of the first dit as > illustrated in the QST review, Figure 1. > > > > My K3 keying does not have that issue as far as I can judge from listening > on a separate receiver. > > > > What is does have is a disparity between keying weighting between MOX > (either front panel switch or foot switch) and VOX/QSK. > > > > Compared with MOX which has characters about the same length as my other > rigs on my keyer's 50% weighting setting (ie it is about right) the > characters in VOX and QSK are shortened. > > > > I simply overcome it by altering my weighting to 58% and not using MOX.

Re: [Elecraft] K3: Keying SB-200
Ralph, If your SB-200 has not been modified, its relay voltage is negative, and THAT will cause problems. The HEXFET in the K3 will take up to 200 volts, but that must be a positive voltage. I would suggest adding a small relay in the SB-200 - rectifying the filament voltage at the transformer with a full wave rectifier and a capacitor should produce about 8 volts - a resistor could be added in series to reduce the voltage at the new relay to about 6 volts. YMMV, but that is the way I would do it. The original wire to the RELAY jack would go to a NO contact on the relay (other side of the contact to ground), and the side of the new relay not connected to the newly formed power source connects to the RELAY jack. That way everything is contained in the SB-200 and no need for external boxes or sources of relay power. 73, Don W3FPR Ralph Parker wrote: I'm just about to connect the KEY OUT to the SB-200 relay.

Here's a thread of discussion on Ultimatic keying for other Elecraft products: http://n2.nabble.com/Ultimatic-keying-in-KX1-K1--td447092.html I've used it in the K1EL keyer, which is done with an 8-pin chip that costs about $1, so I don't think it's that much effort. I'd rather like to try Ultimatic on my K3, but I'm unlikely to try ESSB. I don't think it's productive to criticize feature requests as not being useful.

Re: [Elecraft] K3 Keying - minority opinion?
Well said, Don! I am one of those who can only send [half]decent code with an Ultimatic-mode keyer. Here's another vote for including the Ultimatic keying mode to the list of K3's features. So Wayne, please, please, please, implement this mode as soon as you have the time to do so.

RE: [Elecraft] K3 Keying - minority opinion?
Wayne (and Gary) I hope you and Gary will reconsider adding Ultimatic/Single Lever Paddle support to the K3 internal keyer. I think that more than Don, Dave and myself would welcome that addition to the K3. The elegance of the K3, a rig that rivals and even surpasses many of the very high end radios, is diminished by the need to use an external keyer to use a mode that many find invaluable. Removing the need to add another piece of gear to the table top is not a minor inconvenience. The small size of the K3 seems to be an attempt to make it convenient for field/portable use and to then require another piece of gear to make it work seems to diminish its attempt to reach that goal.

RE: [Elecraft] K3 Keying
I got in the habit of using an external keyer before most rigs had internal keyers. As others have mentioned, external keyers are more flexible and quicker to set than internal keyers, so I continued to use an external keyer. When I first got into contesting in a serious way, I found that virtually all rigs with internal keyers had a conflict between internal and external keying. For example, on Yaesu rigs, the paddle and external keyer input use the same jack. The expectation is that if you use the internal keyer, a paddle will be connected to the jack. If you use an external keyer or PC, the hot lead will be connected to one of the two paddle inputs (usually tip), and the internal keyer will be turned off. You can parallel the paddle and external keyer or PC, but you can't use them together. If you have the internal keyer off, you can key with the external keyer or PC, but not with the paddle. If you have the internal keyer on, you can key with the paddle, but you get gibberish if you try to key from the external keyer or PC (which results in a keyer keying a keyer.) In the heat of a contest it's just not feasible to switch the internal keyer on and off when you want to use the paddle. Of course, the K3 has solved this problem by providing two separate inputs: one for the paddle and one for the key. Now I don't have to turn off the internal keyer to use an external keyer, and have the option of putting a second paddle on the K3 (I haven't done so.) There are other ways to solve the paddle problem in contests. Some contest programs support paddle input through the LPT port. That's one viable solution. The better solution is to use an external contest keyer. As others have mentioned, PC-generated CW isn't reliable on many computers due to Windows multitasking. An external keyer solves that problem, too. I use Writelog's W5XD+ keyer, which has paddle inputs and generates CW in response to commands from Writelog on the PC. It also does paddle, mic, PTT and audio switching for SO2R contesting. The keyer can also be used without Writelog running, though with limited functionality. There's a remote speed pot and L/R switch for selecting the rig. It's possible to build a switch to shift the paddle between the W5XD+ keyer and the rig (or two rigs, or three rigs...), but for me it's not worth the trouble. The W5XD+ keyer is adequate for my needs. 73, Dick WC1M > -Original Message- > From: David Cutter [mailto:[EMAIL PROTECTED] > Sent: Friday, September 05, 2008 1:11 PM > To: elecraft@mailman.qth.net > Subject: Re: [Elecraft] K3 Keying > > I would be interested to know why folks use external keyers in > preference to > the internal keyer. > > David > G3UNA > ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: RE: [Elecraft] K3 Keying
Craig D. Smith wrote: The internal K3 keyer works fine, but I also prefer external keyer(s) for various reasons. OK, the other side weighs in. Several years ago, I built a K1EL keyer [don't remember the model and not sure where the book is right now]. I included an interface to key the radio[s], and inputs from the computer, bug, hand key, and paddle. Worked great with my K2 and TS-850. I built the interface to key both positive and negative lines and actually used that once on someone else's rig on FD. My only complaints were: 1. K1EL keyer lets me send commands in Morse. Sounds great ... not so much so when you are trying to change something in the middle of the contest. 2. K1EL keyer gives me two choices for weight. One is just a bit too "crisp" when I record my signal off the air, and the other is way too much. I got my K3 and HexKey. I now still have the external keyer plugged into the KEY jack so my computer can key the radio and my bug and hand key work. I use the 4 memories on the external keyer for stuff that doesn't change much or at all ... my call, QRL?, general CQ, etc. I have never used the K3 memories. TR-Log handles the memories for contests. External keyer weighting is still just a tad "crisp" for me on the K3. HexKey runs the internal K3 keyer. I can set the weight at whatever I want, I've got it just a bit less "crisp" than the external keyer and it's the paddle I always grab. I can QRS instantly with the front panel knob if someone calls me slower than my CQ. I always thought standard Benchers [with the spring] were really good. Then I got the HexKey :-) My K2 keyer very occasionally will seem to "stutter." It's just discernible, and doesn't happen very often and isn't a problem, my sending isn't that well spaced anyway. I think every now and then the CPU has to do something more important than CW. Haven't noticed that at all on the K3 keyer. Just another opinion, I prefer the internal K3 keyer even though I have an external one too.

Re: [Elecraft] K3 Keying
I think your suggestion would work if I tied the two PTT ouputs (one from K3 and other from the microHam CW keyer) together, isolating them with diodes. Another option would be to have a second set of paddles connected to the K3, for barefoot operation of the K3. I don't see any advantages to doing any of this-- at least for CW operation. The PTT, lead-in and tail features are easily changed in the microHam Router software, in DXBase, and N1MM. I do understand that I would need to use the internal K3 keyer if I wanted to take advantage of its ability to translate Morse into Baudot. 73, Chuck NI0C - Original Message - From: "David Cutter" <[EMAIL PROTECTED]> To: "ni0c" <[EMAIL PROTECTED]>; Sent: Friday, September 05, 2008 1:06 PM Subject: Re: [Elecraft] K3 Keying > Would it still work for you if you used your paddle directly into the K3 > paddle input and pc into the key input, then the programs would still key > directly?

RE: [Elecraft] K3 Keying
The internal K3 keyer works fine, but I also prefer external keyer(s) for various reasons. I have both a WinKey USB and a LogiKey K-5 wired in parallel to the K3 key input. Most of my operating is CW contesting, and the WinKey generates great CW from the N1MM logging program. I have the LogiKey with its 6 memory buttons directly left of my keyboard, so it is pretty much just like an extension of the PF keys to call up one of those memories. I keep the LogiKey set to a lower speed than what I am using on the WinKey. That way, it makes slow speed fills of exchange elements quite convenient when signal levels/band conditions are difficult. I also program in some lesser-used items that I don't want to dedicate a keyboard PF key to. The downside of this, as Rich points out, is that you need to remember to hit ESC sometimes to avoid doubling with yourself. With my shack layout, the K3 is a much longer reach and the K3 memory buttons are in a cluttered panel area and in a vertical plane, making using them not very ergonomic - especially at 2 AM in a darkened shack. ...

I'm wondering if you would want to change the PTT, lead-in and > tail features on the fly, ie could these all be programmed in config? Running a standalone keyer in parallel with computer keying suffers from the disadvantage that input from the two sources is OR'ed, i.e. touching the paddle while the computer is sending CW results in unintelligible garble. One of the selling features of the WinKeyer for me was its integration of paddle and computer input. When the keyer is sending computer-generated CW, a touch of the paddle automatically interrupts computer-sent code and clears the input buffer. Thus, if you hit the wrong macro button in your software, you can start sending with the paddle instead and the PC-generated CW will stop instantly. This eliminates the need to first hit the ESC key on the computer and then switch to the paddle (or to PC keyboard CW). In fact, even if what I want to do is stop the computer output and then press the correct macro button on the keyboard, just touching the dit paddle still seems to be the easiest way for me to interrupt the output stream. Perhaps the K3 firmware will do this too, i.e. give priority to the paddle input over any of the other input sources: DTR on the serial interface, the straight key jack (which is often used for computer keying), or CW generated using the KY software command. I can't tell yet - I haven't found anything about this in the firmware release notes, and my own K3 arrived about two hours ago and is still just a collection of parts. Another feature of the WinKeyer has already been mentioned in this thread: the ability to configure it to add a constant keying compensation of a few msec to every element. Oh yes: will the K3's internal keyer autospace CW elements? That's a useful feature of many external keyers. 73, Rich VE3KI K3 #1595 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Windows always has priority and will interrupt cw keying when it needs to do something else; the result can be awful cw which can be embarrassing in a contest. Winkey takes the data from the pc as ascii (I think..) and generates it's own perfectly timed characters independantly of the computer with which to key the radio. A Microham keyer uses Winkey which also accepts paddle input - this means that the cw sent from your pc (eg from N1MM) will always be at the same speed and setup as that sent from the paddles, one speed knob controls both. I tend to use my Microham cw keyer all the time but admit the keyer in the K3 is excellent. 73, Stewart GW0ETF (K3 145) -- View this message in context: http://n2.nabble.com/K3-Keying-tp841765p841970.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 Keying
I use a Logikey K-3 external keyer because I find that it is just a little bit different than the internal keyer. I'm used to it and seem to make less mistakes with it so that't what I use. On the other hand when I had a K2 I found that the internal keyer was not nearly as good (for me) as the external keyer. With the K3 there is practically no difference at all (to me). I need all the help I can get. I'm old enough now that some days I have a little twitch in my hands. I would have no problem using the K3 internal keyer if my external keyer died or if I was away from my shack. 73, Roger, W1EM -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Cutter Sent: Friday, September 05, 2008 1:11 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Keying I would be interested to know why folks use external keyers in preference to the internal keyer.

Hi David: 1) More versatile CW generation features 2) More memories (in memory-type keyers) 3) More versatile CW memories (often) 4) Greater range of control These are my main reasons for using my Idiom Press CMOS Super Keyer (II/III/or IV) in deference to the K3's internal keyer.

Re: [Elecraft] K3 Keying
Would it still work for you if you used your paddle directly into the K3 paddle input and pc into the key input, then the programs would still key directly?

The WinKey is very versatile, allowing one to key the rigs from the computer keyboard, paddles, an external numeric keypad, or icons provided by the logging program. It also provides a programmable PTT signal with lead-in and tail delays for keying an amplifier. 73, Chuck Guenther NI0C K2/10 s/n 5853 K3 s/n 1061 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I modified my microHam CW Keyer to produce a buffered +5 VDC pulse for triggering a dual-trace scope. The most recent K3 firmware shows that the CW envelope rises ~ 13 ms after external contact closure. And more to the point, the RF envelope matches the duration of the external key closure when measuring from the beginning of the envelope rise to the trailing edge. This closely matches other radios, including many Ten Tec models, and precisely matches the envelope of my Icom 7700 and 7800 (with latest firmware). It's interesting that you use 3 ms of added external compensation as that is my value used on all three transceivers since their envelopes happen to perfectly match in duration. My personal preference would be to have all manufacturers match the envelope time to the contact closure referenced at the time the rise ramp completes, to the beginning of where the envelope begins to fall. If you think about it, the combined rise/fall comprises a full 10 ms in the K3. For that reason, compensation of 3-5 ms sounds less choppy to the ear and more closely matches that of the perfect 1:3 ratio generated by an electronic keyer. Since the required compensation is constant as a function of keying speed, the envelope only needs to be "pulse stretched" to one value, regardless of key speed.

Most good external keyers offer 'keying compensation' in msecs to offset this; my FT990 needed as much as 8ms extra on the characters to give a 1:1 dit ratio in qsk v semi break-in. Just done a quick 'scope check here using my Microham cw keyer and the results are 'inconclusive'. In qsk the space is actually slightly less if measured from the end of the fall to the start of the rise, but slightly more if the dit is measured across the 'top' ignoring the rise/fall time.

Re: [Elecraft] K3 Keying and NR No Effect Here
Thanks Stewart. I loaded the latest firmware this morning (I was using 2.20) but before I did that, I tried monitoring my transmitted signal on another receiver, on the same 80m frequency that I did the test with my UK friend yesterday morning. I cannot tell any difference to the keying between having the NR switched in and switched out. After loading 2.23, my signal sounded exactly the same on my other receiver and a report from a European station on 20m said the keying was "perfect" and there was no sign of any clicks. I now intend leaving well alone and am putting the experience down to one of the mysteries of life! 73 de Chris, G4BUE On 15 Aug 2008 at 2:04, GW0ETF wrote: > > > Don Ehrlich wrote: > > > > I just keyed my K3 with and without NR (all settings) while > looking at the > > keying waveform.

Re: [Elecraft] [K3] Keying software improvement suggestion (was: Logging programs and internal keyer)
Thanks again to all who responded on- and off-line to this subject. Two things I learned here: There are external keyers that provide superb support for high performance contest software, but also, great software can indeed produce great CW over serial or parallel ports without the extra hardware. The lower-performing programs don’t because they use loops, timers, or other task-dependent features to send the CW. One of my objectives is to minimize the number of cables and boxes on my desktop. If it could be made to work right, DTR/CTS keying would do the job. Here are the problems, though. First, it keys your radio when the computer reboots. This is a deal breaker for me. I’m too scatterbrained to remember to disable it when I’m not using it. Second, there’s no feedback from the radio to the software. When you touch a paddle or key, you want the software to stop sending. So two improvements are needed to make this work great: 1. An RS232 command to enable/disable DTR keying so that it’s enabled only when your contest program is running. 2. An auto-info response that sends an event to the computer when a key or paddle is touched. Then if we can get the software authors to implement it, and keep the internal keyer at the same speed as the software, I think this would work very neatly. Plug your key into the rig, the rig into the computer, and off you go. Thanks for listening!
