Hi Geoff I would think that the phase noise limitations of the K2's design would limit its appeal. I would be more interested in a K3-Junior Maybe this K3 junior would have a single receiver Inbuilt power supply 200 watts 50 volt or higher fets Layout like Yaesu FT950 VFD display - blue external TXCO input A real analog S-meter Front firing speaker A big 10 watt audio PA Amplifier tuning pulser(audio) 2 tone generator controls on the front panel Built in directional coupler for TX monitoring Optional control port for a DSP receiver like QS1R(or even a Elecraft version of the QSR1) A high performance tuner like the SGC230 SO2R interface built in for 2 X K3 JNR's USB interface Ability to select and key 2 amplifiers with different drive power levels In built dummy load NTIA specifications for the TX PA that can work into a 3:1 VSWR load Blue tooth headset support Anyway its a nice dream, however this radio would be the best selling radio in the world I would think. It would certainly make the new Hilberling look like very poor value for money I would buy 2 or even 4!

Re: [Elecraft] [K2] has the k2 a future?
The K2 is a very mature product, and I don't anticipate adding further internal modules to it. I've thought about a Li-Ion battery as a replacement for the present gel-cell, but it's still too expensive and is thus left as an exercise for the reader. The P3 should work with the K2, though less tightly integrated than with the K3. If that pans out, we'll post details later.

[Elecraft] KX1: Several Operating Questions
Hi, All, I have enjoying my new KX1. This radio is a real sleeper. I should have gotten one long ago. 1) Last night I tried to listen to a MARS net just above the 80 meter ham band. I found out that I could not get into USB mode on 80 meters, which was a big dissappointment. I could get into USB mode on 40, 30 and 20 meters. Is there a reason for this? 2) The recommended max voltage is 14 Volts. Is that before the diode or after it? The reason I ask is that my BAT function gives a reading of .4 of a Volt lower than the external battery voltage. I am using an external 3 cell LI-ion pack with great results, but want to try a 4 cell pack. However, I fear the Voltage would be too high for the rig. I would hate to put in a bunch of switchable diodes in series to limit the voltage when it may be possible to run with the higher voltage and put the power into the antenna itstead of heat. Any suggestions? 72, Steve, W2MY, AAR6CX __ 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] Re： [K2] has the k2 a future?
Hello Julian, Yes, I agree with you. Elecraft is very clever in segment the market to suit different market demand. Although I do not always clap my hands for K3, K2 is definitely the best choice for portable use. Upon replacing the Lead acid battery in the KBT2 with Li-Po cells, the K2 is now very light weight and can be operated for lng time. It is the greatest portable rig when compared with the others. In the past, I asked whether K2 was good for ARES. Now, I would say that it is good for QRP ARES operation. Just throw up a piece of wire of about 30 feet and press the tune bottom and let the KAT2 tune. After that, you are on air. Trouble free and no headache.

Re: [Elecraft] has the k2 a future?
I am not certain where that statement about phase noise comes from, nor if it is valid. The K2 comes in at -123 dBc (or -124 dBc) in the phase noise category. The transceiver comparison list at the Elecraft website does list phase noise as measured by ARRL and by Sherwood. I did a quick count - There are only 5 listings that have phase noise measurements better than the K2 (one was the K3), and 19 ranked worse than the K2. I don't have phase noise measurement capability here, so I must depend on the ARRL and Sherwood test data, but those measurements are well respected by most hams. The Sherwood list is more extensive, and lists LO noise. In the 27 transceivers at the top of the list, there were 16 better than the K2, 3 equal to it, and 8 listed worse - so IMHO, the K2 is a bit below average within the top 27 listings - not too shabby for a 10+ year old design. 73, Don W3FPR juergen piezo wrote: I would think that the phase noise limitations of the K2's design would limit its appeal. snip __ 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] IF Output Buffer Gain Mod
Before the recent change in the IF sample circuit, the transfer gain was around -15 to -17 dB. In other words, a signal input to the antenna will appear at the IF sample port about 15 dB below the input level. This assumes the K3's preamplifier is off and, of course, that the K3 is tuned to within a couple hundred KHz of the input test signal. My understanding of the modification (I have not made the change to my K3, but I have looked at the change in simulation) is that the transfer gain is now around -5 dB or so when measured into a 50 ohm termination. IF sample ports of commercial and military receivers tend to be of two types, and some receivers have both. If intended for panadapter use, the net transfer gain usually is around 0 dB, i.e., the output signal level at IF is approximately equal to the RF input signal level. The second type of IF output is used for external demodulation, and will often have considerable gain and is usually at a later IF stage and often will be behind the receiver's selective filtering. This type of IF sample is also usable to look at the signal envelope, but is close to worthless for wide band panadapter use. The K3, of course, has an IF sample of the first type. My Kenwood TS-940 has both, a panadapter usable high IF sample at 8850 KHz and the second type of IF output sample at 100 KHz. (These are from memory, so excuse me if I've made an error in the exact frequencies.) A typical oscilloscope will have a usable signal deflection at maximum gain in the range of a few millivolts per cm or graticule division. Let's say it's 5 mV/div, not an unusual value. An envelope deflection of 2 divisions (+/- 1 division) has a peak-to-peak voltage therefore of 10 mV, or an RMS value of 3.5 mV. If 50uV = S9, and if the net transfer gain of the K3 to the IF is -5 dB (it will probably be better than this since the oscilloscope has a high Z input) then it will require an input signal level of 42 dB over S9 to yield 2 divisions peak-to-peak deflection. Hence, it's not at all surprising that one will not see an envelope displayed when an oscilloscope is connected to the K3's IF sample port with normal antenna signal levels. Spectrum analyzers or panadapters, of course, are designed to be much more sensitive, responding to signal levels in the 1 uV range or less.

But I have not tested it. So your email triggered a curiosity to check it. Since the test gear is in the basement and the K3 is here in the shack, I thought of connecting my FT817 and listening to the IF output. The IF center frequency is 8.215 MHz more or less and so you can listen above the IF and below the IF to what stations are transmitting. The FT817 was chosen because it is highly portable and tunes to 8.215 MHz easily. You could do an A/B test on signal level. There were a lot of signals on 20m and so I had a lot to hear. If you put the K3 on say 14.350 MHz, for example, then a signal at 14.325 MHz is going to be 25 KHz above the 8.215 MHz IF or 8.240 MHz out of the IF output. This is because the IF signal is inverted and goes up in frequency as you go down, in this case down from14.350 MHz. The signals are going to be LSB for the same reason. You could tune for WWV at 10 MHz to have a stable signal for the before/after test. By the way, this is an odd and awkward way to add a sub receiver to the K3. Don, N0YE .I see about the the same on my new K3 that had the mod factory installed. I had expected to be able to look at IF noise with my oscilloscope like I do on my FT-101E but the level is too low and there's some pickup of other signals away from the IF so you need some gain and some selectivity ahead of the scope. I suppose I'll get an 8 MHz crystal for the 101 because I'm really curious about how well the K3 noise blanker works on different noises that I'm used to seeing on the 101. I did a bit of blanker experimenting last night and sent this note to a friend W5JAW, who is very experienced in blanker design, as I am. I'm accustomed to looking at the IF noise on my

have yet to inquire about that.
Anyway, here are the messages I use for this... theoretically this
should work for SO2R, but I haven't really tested that thoroughly (I
only have one K3 at home)...

The main benefit of this is that it avoids all of the hassles of
getting the audio routed through the computer working right and
sounding decent - instead you just plug your headset (or fav mic)
straight into the radio and go. Message recording is done with the
buttons on the radio. Listeners should be unable to distinguish
recorded vs live audio, other than by the repetition.
A possible down-side is that N1MM doesn't know when the playback of a
message ends - in fact it doesn't even know that a message is being
played. Things like repeating (or, worse, dueling) CQs could be a bit
tricky.
For something quick and easy, it works quite well...

Re: [Elecraft] K3 - KDVR
Brett,
As I see it the advantage is that you can send messages from the keyboard
(particularly useful if you have an SO2R setup with the radios spread
apart). Furthermore, you can integrate the message sending into the normal
message sending functionality, like message repeating and hitting ESC to
stop it. I do that with my logging program, CQPWIN, and find it's more
convenient than continually using the radio buttons. I do have to have the
program calibrate the length of each message first, to be able to do the
repeating properly. It works fine.

Re: [Elecraft] K3 - KDVR
For contesting, it is WAY more effective to be able to control the DVR
from N1MM than from the front panel of the K3. It's tiring and wastes a
lot of time to move your hand back and forth between the keyboard and
the rig multiple times for every contact. For example:
1. move hands to K3 to press M1 for CQ or M3 for thanks/73
2. move hands to keyboard to type callsign of next caller
3. move hands to K3 to press M2 for report; wait for acknowledgment and
report
4. move hands to keyboard to type report
5. repeat
Requests for repeats add additional motions.
When I bought my K3, I specifically did NOT buy the DVR because I didn't
think it could be controlled from the logger. Now that I know
differently I'm seriously considering buying one for the same reasons
described by N6ML below.

Re: [Elecraft] K3 - KDVR
By the way, I since found out that the RX; command is sent to the K3
on hitting Esc[ape] iff the COM port configuration has Radio PTT
via command checked. This has the nice effect of canceling DVR
playback on hitting Escape.

should work for SO2R, but I haven't really tested that thoroughly (I
only have one K3 at home)...
F1 CQ,{CATA1ASC K31;SWT21;}{CATA2ASC K31;SWT21;}
F2 Exch,{CATA1ASC K31;SWT31;}{CATA2ASC K31;SWT31;}
F3 Thanks!,{CATA1ASC K31;SWT35;}{CATA2ASC K31;SWT35;}
F4 {MYCALL},{CATA1ASC K31;SWT39;}{CATA2ASC K31;SWT39;}
The main benefit of this is that it avoids all of the hassles of
getting the audio routed through the computer working right and
sounding decent - instead you just plug your headset (or fav mic)
straight into the radio and go. Message recording is done with the
buttons on the radio. Listeners should be unable to distinguish
recorded vs live audio, other than by the repetition.
A possible down-side is that N1MM doesn't know when the playback of a
message ends - in fact it doesn't even know that a message is being
played. Things like repeating (or, worse, dueling) CQs could be a bit
tricky.
For something quick and easy, it works quite well...

[Elecraft] K1 question...
Hi y'all! I have noted that most of the posts in the elecraft reflector are about the K3. I hope this isn't out of line. I bought a K1 awhile back because it was billed as a great first-time builder's kit. As one of those first-time builders, I suppose I'd agree, but I've run into a few rather basic questions and I'm undoubtedly driving Gary up the wall with them. I'm a rank beginner on all things electronic I'm afraid. He's set me the task of building an RF probe (which I'm getting to) and told me to get a signal generator as well. I need to do the signal tracing the manual suggests (Appendix E, p5) and wanted to build the signal generator shown in schematic on that page. I have the KFL1-4 board with 17, 20, 30 and 40 meters and am only hearing signals on the 40 meter band. I thought I'd build the signal generator with a switch to change between crystals. I'm looking for some advice: I have one power supply (a Samlex SEC-1235M) and I guess I'll need another power source for the signal generator. As I looked at the Samlex site (http://www.universal-radio.com/CATALOG/hamps.html), I saw both linear and switching power supplies. Does it matter which kind I get? Any other suggestions for inexpensive options? I suppose I'll stop with one question for now. Thanks hams!

What makes this easier than just using the radio? Seems to me that
its just as easy to press M1 as F1... Also now that VOX can now stop
tx of a DVR message stopping it is as simple as pressing nearly any
button or beginning a transmission. Heck ESC would probably also work
if you initiated w/ M1 if it works when you press F1.

Hi Barry,
Yes, I was using the KDVR3 for voice keying - really I only used it
for my CQ(s). N1MM doesn't explicitly support use of the KDVR3, but it
does allow you to send arbitrary commands to the K3, so I use the
commands that emulate pressing the M1-M4 buttons. I was pleasantly
surprised yesterday when I instinctively hit the Escape key to
interrupt my CQ when I thought I heard someone calling, and it
actually worked! I'm really not sure why it works - there may be some
hidden magic that sends a stop command to the K3 on hitting Escape. I
have yet to inquire about that.

Re: [Elecraft] K1 question...
Hi Tom, Both varieties will produce the DC voltages you need (as would a few batteries). For your purposes, the differences between the two types may not matter. Linear power supplies use a conventional transformer to convert line voltage (117vac) to a lower voltage (typically 15-18vac), which is then rectified by diodes, filtered by capacitors and (usually) controlled by a voltage regulator to 13-14 volts DC. Unfortunately, as the current goes up, the size of the transformer (which usually contains an iron core) goes up as well; a 20 amp 12V linear power supply might weigh 15 lbs or more. Switching power supplies generate a high frequency AC voltage, which does away with the need for the heavy transformer. So switching supplies tend to be lighter than linear supplies for the given amount of current produced. The disadvantage is that the high frequency AC can, in poor designed/shielded supplies, generate hash that can be heard in your receiver. QST has tested a number of switching power supplies recently, you might check to see if the supplies you're considering have been evaluated. 73, Dave KQ3T Thomas R. Hauff wrote: Hi y'all!

Re: [Elecraft] K1 question...
Tom, Yes, K1 questions are welcome here - after all, it is an Elecraft reflector, not a K3 reflector. The relative newness and the popularity of the K3 does make the bulk of the traffic K3 related. For that reason, many on the reflector want us to remember to put K1, K2, K3, etc. in the subject line so their email sorters can deposit the posts into the appropriate folder. Switching the crystals on your signal generator is a good idea, although I have that generator wired up ugly style on a piece of copper clad board, and I used a strip of 3 'machine pin' sockets (like in a DIP socket) as a crystal socket, so I can plug in any variety of crystals for whatever band I need - easier than a dedicated switch IMHO. There is no reason that oscillator cannot be powered from a 9 volt battery, or a regulated 9 to 12 volt 'wall-wart' (most are *not* regulated) - it takes very little current - certainly less expensive than a separate power supply, and more portable. Since your current power supply has a 35 amp ICS, 30 amp Continuous rating, it has plenty of reserve current, you should be able to use that supply for the oscillator as well as the K1 - in fact that supply will easily run most 100 watt class transceivers. BTW - there is no reason the oscillator has to look 'pretty', it just has to work (and hold itself together during use). Many QRP friends and I build things of that nature in an Altoids tin - it can hold both the oscillator and the battery. Switching power supplies are lightweight, and many are excellent - but some do have RF emissions high enough to be bothersome in a ham station - check the ARRL reviews if you want data on any particular one (assuming they have reviewed that one). Normally linear supplies are noise-free, but transformers are heavy, so a high current supply may be quite weighty. I have an Astron RS-35A (rated 35 amps ICS) that powers everything in the hamshack and lives on the floor under the desk. If you are just beginning, you may want to get a DC power distribution system (I like the ones with Anderson Powerpole connectors - like the Rigrunners) rather than an additional power supply, you will likely be adding additional transceivers and accessories as time goes on, and one power supply can possibly serve them all if you can distribute the power. For your K1 problem - yes the strong oscillator signal will likely help you. The most common problem encountered in tuning the K1 is getting the pre-mixer bandpass filters aligned correctly. You must peak 30 meters before peaking 40 meters, and similarly, peak 17 (or 15) meters before peaking 20 meters. Failure to follow that sequence will cause all kinds of frustration. The trimmer capacitors will normally be set close to the center position - if you do not find a peak near the center setting, there is a problem to be found (like an extra turn on the toroids). When counting toroid turns, count the number of times the wire passes through the center - a straight wire through the center of a core is one turn, and a full wrap around the core is 2 turns. 73, Don W3FPR Thomas R.

Re: [Elecraft] K3 - KDVR
By the way, I since found out that the RX; command is sent to the
K3
on hitting Esc[ape] iff the COM port configuration has Radio PTT
via command checked. This has the nice effect of canceling DVR
playback on hitting Escape.
Thanks Iain. Works like a dream when I figured out that I simply need
to cut-n-paste the{CATA1ASC K31;SWT21;}{CATA2ASC K31;SWT21;} and
similar commands from your earlier message into N1MM's config SSB
messages option for the relevant message, in place of the wav\
stuff in there by default.
I guess we can trigger messages M5-M8 as well with the appropriate
commands? I'm thinking that, for a multi-single club effort in CQ WW
SSB, we might get the two main ops to record their messages in banks
1-4 and 5-8 respectively. Mind you, it's easy to re-record any
message on the K3, much easier than messing around with WAV files on
the PC.
Anyway, I think this feature might *finally* be enough for the K3 to
displace the FT1000's from the club!

[Elecraft] K3 - computer communications
I use Logic 8 as a logging program, and it has communicated fine over a serial port with my K3 (s/n 1826). Today a windstorm dropped a tree across a power line, and the power surged on and off several times before going off completely. The computer is a Dell laptop in a docking station. The computer is powered through a UPS. My K3 is powered by a stout Astron RS-35M linear supply (that is not on the UPS). I don't know if there is a causal agent at work, but now I have communications issues. If I turn the radio on and launch Logic 8, the computer and radio seem to communicate OK at first. Then after maybe 5 to 10 minutes, the computer puts up a message that the link has been lost and the communications stops (no frequency updating, etc.). If I close and reopen Logic 8, they communicate for a bit before the message comes back. Any suggestions?
