If your K2 serial number is 3000 or higher, that mod is already installed, and you do NOT have to do it. Notice that it refers to the REV A RF board. Rev B boards are used in K2s with a serial number of 3000 or more. Also if your K2 is serial number 3000 or more, when you get to page 59, you should not do the Control Board wiring changes shown there. Those changes have already been embedded on the REV B board.

Re: [Elecraft] k2 and kpa 100
Hello Don,
It does not matter to your Frenchman, my Englishman and far from being the one
you master!
I use google translation HI! To try to make me understand as well as possible
For mounting the KPA 100 I arrived on page 22, "initial test" everything is OK
But I have a doubt about "AF pad", ground.
The measure gives infinity is this correct?
For the modifications of the K2, I speak of this one:
K2 Modifications for use with the KPA100
June 12, 2002 Rev. A (applicable to all K2 Rev. A RF boards) - Wayne Burdick,
N6KR
The transceiver meets FCC spectral purity requirements on 10 meters, especially
When used at medium (11-50 watt) power levels. Not all K2s require these
changes, but as a precaution, we strongly recommend
Making them. If you have any questions, please feel free to contact me.
Need be removed to make these changes.
QRP K2, a parts kit is available for $ 15.00 plus shipping. Order P / N
E850093 (10M and VFO / ALC mod kit). You can write this order in the comments
section at the bottom of our regular order
Form, or contact sa...@elecraft.com. Scott or Gary in support (we're trying to
keep them focused
On their regular tech support duties.)
10 -12-meter band-pass filter that improves rejection of both the transmit and
the receiver.
NOTE: If you have already built your K2, be sure to re-align the 12M / 10M BPF
section after you complete this mod.
Part II is a modification to the VFO ALC circuit; It prevents a VFO buffer
(RF-U3) overdrive condition that may occur on some K2s when
Switching to 17 or 10 meters. VFO drives at U10.
Refer to the illustrations on the next page when locating components and making
these mods.

A), manual instructions (see page references below),
And RF board schematic (Appendix B).

Christophe,
If your K2 serial number is 3000 or greater, those modifications do not
have to be done at all, they are already present on the RF Board.
You do need to mount the headers at P3 and P6 and remove pin 4 from the
10 pin header at Control Board P4.
Those changes may be made at any time.
I am confused about your question of "first tests step 2 of the KPA100
with dialog and assembly in the K2" I think we have a language barrier.
Please restate with reference to the page number in the manual.
Assembly, Part 1 (page 12) comes before the "Initial Tests" (page 22)
and the PA transistors are not mounted.
Sorry, but my French is lacking. I spent 15 months in France with the
Army in 1963/4 but learned only enough words to buy what I needed or
order a meal.
73,
Don W3FPR

Re: [Elecraft] K2 - INFO 80 problem
hello juliano, I'll put the single 080 info Book of troubleshooting, if it can help you If you saw the message INFO 080, the I/O controller (IOC, RF-U1) or other auxBus device did not respond to messages from the main processor (MCU). Turn power OFF and back ON; if you hear some relays switching on power-up, the IOC may be OK, and the problem is likely to be with the AuxBus (081) If you do not hear any relays switching on power-up, your IOC (RF-U1) may be defective. Inspect U1 carefully to see if you have installed it backwards or if any pins are bent. Pull U1 out, check its pins, then re-install it, making sure all pins make good contact with the IC socket. Check the 4-MHz oscillator (075). Remove the bottom cover and verify that all pins of U1’s socket are soldered, as well as those of the 6V regulator (RF-U2), and U1’s 4 MHz oscillator (RF-Z5). With power ON, check all voltages associated with U1. You should see 6V at pins 1 and 20 at all times, even when the IOC is sleeping (not being accessed by the MCU).

All the SSB filters should be aligned - AND - in many (most) K2s built in the last several years, the suggested settings for the SSB filters other than the OP1 BFOs do not work well. That is because the varactors have changed (the type has not changed, but the capacity range has increased - blame the manufacturer!). The result of this varactor variation is that the filter width displayed by the K2 is usually much more narrow than the actual width (not true for the OP1 filter which has no varactors). I do not know of any way to easily find the actual width of the filter other than using an audio spectrum analyzer like Spectrogram. 73, Don W3FPR On 5/20/2013 1:25 PM, Ralf Wilhelm wrote: Hi, Christophe and Don, There is a point I don't understand: The K2 switches to VFO below rx frequency on 15 and above (main manual page 85) thus resulting in sideband inversion.

When using CW mode, the K2 transmit frequency will be offset from the receive frequency by the amount of the sidetone pitch setting you have in the menu. If you are in CW normal, transmit will be lower, in CW reverse, it will be higher. There is no offset for SSB or RTTY modes - the transmitted carrier (suppressed) frequency will be the same as the receive carrier frequency.

Moved radio up to bedroom this morning w/ dummy load, powered by an optima blue top deep cycle battery. Same results. Could tune in to CW signal using yaesu radio in basement. Ordered the optional VCOSHLDKT today anyway since the K2 will end up down by the power supply.

If so, isolate the K2 by moving it away from everything and see if the ripple goes away. If the problem disappears with the isolation, you can install the optional VCOSHLDKT which shields the VFO inductor. 73, Don W3FPR On 10/21/2012 11:04 PM, Calvin Jones wrote: Hello, First time posting to the list. Completed K2 #7239 today. Made a contact with a station on cw, 10 watts, 7.1065 mhz. He reported back that my CW signal had a very heavy ripple on the signal. I connected the output to a Oscilloscope and was able to see a ripple on the waveform when keying a solid carrier at a few watts. Also listened to my signal on another receiver and could hear a very bad modulated CW tone. This is a barebones K2 with no options installed at this point. Every measurement in the testing was all within specs and the alignment of the radio had no problems. Power output on all bands was OK. Thanks for any help in correcting this problem. __ 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 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 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
