[Elecraft] K1EL's WK-USB keyer supports Ultimatic mode
I just built the new WK-USB keyer from K1EL. It can be use with a computer USB port, or in stand alone mode. It operates in Iambic A, B, Bug, or Ultimatic modes. I have not tried Ultimatic keying for 10 years, but was able to send OK with it after a few minutes of practice. I would think that either the Ultimatic mode with dual paddles or a single lever paddle with an iambic keyer would be equally easy to master. Now that I have learned iambic keying, I will stick with that mode myself. Hope this gives another option to anyone who finds iambic keying frustrating.

[Elecraft] N-Gen Output - Thanks
Hi Guys, Thank you very much for your illuminating assistance with N-Gen output. I think that I now understand the principles which I had forgotten after 40 years. Or, perhaps that was a question in the exam that I took a punt on not getting! It is amazing how the sins of our youth come back to haunt. My only excuse is that now that I am retired, I am getting back to refresh my understanding without the pressure of forthcoming examinations. 73 to all on the list.

RE: [Elecraft] Amp keying circuit K2
Hi All, Thanks for all the responses to this - much appreciated. I'm afraid it was a simple case of me not reading the instructions on the keying circuit. The FL-2100B pulls 20v on its keying input, whilst the circuit for the K2 is only designed for 5-12v !! This is clearly written on the instructions with the circuit, which I neglected to read. Does anyone have details of a simple circuit I can build, so I can use this with my FL-2100B ?? Again, many thanks for the all the replies !!

The amp keying circuit should work unless the output transistor is being forced into conduction from whatever voltage is being applied on its open collector - it should not be if the voltages applied are within a normal range. Without the amp connected, you can check the base voltage of the 2N transistor - it should be very close 0 volts during receive and about 0.7 volts (the emitter/base junction voltage for the 2N) during transmit. If those two conditions are not true, then you have something wrong with the keying circuit wiring. During receive, the 2N should be cutoff due to the low voltage at its base and should not conduct even with voltage applied to the collector. Be certain the resistance in the emitter path is quite low - a bit of resistance there could cause the output transistor to misbehave. If your problem still is not solved, try measuring the circuit output transistor voltages (to K2 ground) with the amp connected and the K2 in receive. The emitter should be zero volts, and the base should also be very low, while the collector should measure at the voltage applied externally from the amp. Be certain you have a good low resistance connection from the amp ground (terminal E) to the K2 ground and a good connection from the amps RY terminal to the keying circuit's output collector. If you find the conditions above are OK, you likely have a bad 2N. 73, Don W3FPR > -Original Message- > > Just a quick question.. > > I've just installed the parts in my basic K2 to externally key an > amp.

Re: [Elecraft] Re: [WriteLog] K2/XV with Writelog
We know that the K2 works with Writelog in all sorts of serial interfaces, including USB serial adapters. I would wonder if the PCI serial port is somehow expecting handshake signals which the K2 doesn't have (and presumably you do not have connected). If the port is looking for an input handshake that never occurs, it will tend not to work. You might look at the connector to see how RTS/CTS and DSR/ DTR are connected - they may need to be looped back for that card. Also check the serial port docs to see what it really needs. Good luck!

Re: [Elecraft] Rework Eliminator
Hi Bill, Welcome to the list! I added the Rework Eliminator boards to my K2, and I'm happy I did. I would recommend it to you for two reasons. First, you will spare yourself from reworking your K2 when you add the accessories. With the Rework Eliminators, to install an accessory board you just pull out the un-module and plug in the accessory board. Second, should you ever need to troubleshoot your K2, the Rework Eliminators make it very easy to discover whether the problem lies with an accessory board. Otherwise, should that happen you would be forced to rework your K2 just to do that simple troubleshooting step. The Rework Eliminator web site at http://www.unpcbs.com/ has all the documentation you will need to make an informed decision. The diagram at the very center of the User's Guide is very helpful for getting the basic idea. I agree with Don that you don't need the Upgrade Combo, which includes all the headers and standoffs and such which come with the accessory boards. Just get the "Missing PCB Parts" kits for the options you didn't buy. That will also save you a good fraction of the expense. If you do decide to go with the Rework Eliminators, make sure that you read the Companion Guide before you start building the K2. The Usual Disclaimer applies -- I have no financial connection to Ken and Gary other than being a satisfied customer. 73, - Rob W7GH K2 #5004 On Mon, 17 Jul 2006 15:03:47 -0700, Bill Carpenter <[EMAIL PROTECTED]> wrote: New to the list and I will be building the K2/100 with KSB2, K160RX, and K60XV soon.

RE: [Elecraft] Rework Eliminator
Bill, Since you will have the headers required for most of the options, you could get the boards and the on-board parts. The headers that you would not have are for the KAF2/KDSP2 and the KNB2, and you could order those headers (and the KNB2 standoff) separately. You will need a 2.7k resistor on the RF board for the KNB2 RF Board changes. The Rework Eliminator instructions will tell you how to proceed, but you will have most of the parts in the K2 option packages. I do not believe purchasing the entire kit with all headers and hardware would be wise if you have ordered the K2 options. 73, Don W3FPR > -Original Message- > > New to the list and I will be building the K2/100 with KSB2, K160RX, and > K60XV soon.

RE: [Elecraft] Re: [WriteLog] K2/XV with Writelog
Raj, It could be a timing problem created by the way your operating system handles the PCI card ports as opposed to its handling of the native com port. If you are using WinXP, something like that is entirely possible. Nothing in your KIO2 is broken. The K2 operates with no handshaking, so timing delays and latency caused by the operating system are the most likely sources of the problems. 73, Don W3FPR > -Original Message- > > Symptom: Freq polling shows wrong frequency and cycles through the bands > Rig: K2 with the KIO2 and 4 transvertes XV50 thru XV432 > Serial port: 4 port PCI card RocketPort > > Following Hank's suggetion, I tried the single COM1 that I have on the > motherboard.

Hmmm ... that might be backwards? I haven't kept up with the rules, but due to a scheduling error on my part, my Mom (the driver) and I arrived at the FCC in Los Angeles about 3 hrs early (I was almost 16) for the Extra exam. The examiner told me to fill out the app and take the 25 WPM 2nd telegraph code test. If I passed, I'd get credit for the 20 WPM Extra. I did pass (my teen friends and I were in a contest for top code speed and we were all: 1) The Nerds at school; and 2) at a bit over 30 WPM). I sat for the written, nothing to lose, and passed ... exactly. My Elmer got me a job as a relief op at a coastal marine station during my senior year in HS, which was maybe the most fun job I've ever had despite the fact that the OT's on my crew knocked the 16 yr old kid around a lot. My 2nd telegraph finally lapsed as I was finishing college. Maybe they've changed the morse requirements since then. The Marine Radio Historical Society in San Francisco has restored the old KPH site at Point Reyes and Bolinas CA. They recently applied for and received the license KSM, probably the first such license granted in maybe 20 years. On Saturdays, from about noon to 1600 pacific time, they run their traffic wheel on 6474 Kcs and handle a little traffic with mainly other historical ships. They'll sometimes activate KPH on 425 KCs during this time (and on Marconi Day), and often send press at about 20 WPM. MRHS also holds the call K6KPH, and when they're operating, they guard 7050 KCs and 14050 Kcs for calls and handle traffic for station visitors. They appreciate reception reports and will QSL on authentic Maritime Radio Telegram forms. Connection to Elecraft: I copy KSM on 6474 Kcs pretty well with my K2, and use the K2 as the 80m IF for my Palomar LF/VLF converter when listening on 425 and 500 Kcs. 73, Fred K6DGW Auburn CA CM98lw ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Amp keying circuit K2
David, No question is quick if you need to understand what is going on ! The amp keying circuit should work unless the output transistor is being forced into conduction from whatever voltage is being applied on its open collector - it should not be if the voltages applied are within a normal range. Without the amp connected, you can check the base voltage of the 2N transistor - it should be very close 0 volts during receive and about 0.7 volts (the emitter/base junction voltage for the 2N) during transmit. If those two conditions are not true, then you have something wrong with the keying circuit wiring. During receive, the 2N should be cutoff due to the low voltage at its base and should not conduct even with voltage applied to the collector. Be certain the resistance in the emitter path is quite low - a bit of resistance there could cause the output transistor to misbehave. If your problem still is not solved, try measuring the circuit output transistor voltages (to K2 ground) with the amp connected and the K2 in receive. The emitter should be zero volts, and the base should also be very low, while the collector should measure at the voltage applied externally from the amp. Be certain you have a good low resistance connection from the amp ground (terminal E) to the K2 ground and a good connection from the amps RY terminal to the keying circuit's output collector. If you find the conditions above are OK, you likely have a bad 2N. 73, Don W3FPR > -Original Message- > > Just a quick question.. > > I've just installed the parts in my basic K2 to externally key an > amp.

Re: [Elecraft] N-Gen Output
The N-gen produces noise power that is approximately 35 dB greater than that produced by a 50 ohm resistor. At room temperature a 50 ohm resistor produces a noise power of -174dBm per Hertz of bandwidth. So in a typical CW bandwidth of 500 Hz, the N-gen noise power output is approximately -174+10log(500)+35= -112 dBm or 0.56 microvolt.

RE: [Elecraft] N-Gen Output
Hi Stewart and Kevin Calculation for white noise are a bit tricky - here goes: The power output is specified as Excess Noise Ratio. This is how much more power the N-gen produces compared to a 50 ohm resistor at a temperature of 290 Kelvin. How much power that is depends on bandwidth. If you double the bandwidth, you get twice as much noise power. The equation is Pn=kTB. So, at 2300 Hz bandwidth, at 290 K, we get 1.38x10(-23)*2300*290=9.2x10(-18) watts out of a 50 ohm resistor. Since we're 35 dB above that, we've got a power out of 9.2x10(-18)x3162=2.9x10(-14) watts. Since this is a 50 ohm source, voltage output is only about 1.2 micro volts. Of course, this is in RMS. Now, the oscilloscope bandwidth is going to be much larger, let's say 50 MHz. So the noise bandwidth increase by 5000/2300, which in dB is 43 dB. So voltage will look higher on the scope, by the square root of that, or about 137 microvolts. Again, this is RMS, but not like for a sine wave. You should often see peak values up around 0.4 millivolts in a very random fashion. Might be a bit hard to catch unless you have a delayed sweep circuit and a fast sweep rate.

RE: [Elecraft] K2/XV with Writelog
Raj, That certainly sounds like a Writelog problem. If the K2 works properly with another program, then there is nothing wrong with the K2 interface or your connections - that leaves only the driving software and a small chance that the sequence of commands is creating an unexpected path somewhere in the K2 firmware. There are methods of polling that are known not to work properly for all combinations. As an example, the polling done by the N4PY rig control software causes problems if the KRC2ACC is incorporated into the setup - the N4PY software works FB without the KRC2ACC included, and works nicely with the KRC2 (only the 'ACC' versions gives problems). So far, Carl has not been willing to change his software to avoid the problem. 73, Don W3FPR > -Original Message- > > I tried to use my K2/KIO2/XV combination with Writelog for last > weekend's CQWW VHF competition and failed. > > I hooked up the K2 to a serial port and set it up on Writelog.

RE: [Elecraft] What should the power output of the K2 be?
Sam, There is no one single answer to your question because it depends on the particular meter's response and will differ from one meter to another. The K2 bargraph peaks will usually indicate the peak power more readily than a 'peak reading' analog power meter. The reason is that the bargraph responds rapidly while the analog meter has mechanical mass to move and will respond more slowly - 'damping factor' is the technical term. Most meters simply add an RC network to provide conversion from average to peak, but there are many dependencies on the accuracy of that conversion. To really determine the PEP level, the best instrument is a 'scope. Connect the 'scope (with a compensated 10X probe) across the load. Then transmit CW at the power level you wish to set the SSB PEP value at and note how far it deflects on the 'scope. Now transmit with SSB and make the peaks equal to the deflection level you observed with the CW signal. Once you have determined the real PEP value for a certain power level, you can connect your external power meter and see how far your voice deflects the meter with that power level. With CW, the Average Power and the Peak Envelope Power are equal, but with SSB, the average power will be considerably less than the PEP - how much less depends on the voice, the amount of copression, etc. In any case, a 5 watt CW signal will contain considerably more power than a 5 watt SSB signal. 73, Don W3FPR > -Original Message- . > > > This has always been a confusion factor for me. > So with an external meter, > running CW you should have it's scale set to peak or average? > > And if you use the same meter on SSB > and do the long 'hello' thing, > which setting gives you the more accurate > (in relation to setting the output to say 10w) reading for a contest? > > TIA > -- > GB & 73's > KA5OAI > Sam Morgan > ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The external meter is showing the average output, not the peak. This has always been a confusion factor for me.
