Re: [Elecraft] replacement parts delay
Hi, I'm the owner of K2 #5346 and so far the customer service I have gotten from Elecraft and especially from Pam was fantastic. I've ordered quite a lot of thing and didn't yet have the time to do the full inventory (K2, KDSP2, KSB2, KPA100, KNB2, K160RX). I do an inventory before each major step and so far I couldn't find anything missing BUT I have seen that there is one broken core inside of KSB2. I feel quite bad requesting parts 5 time if I find anything else missing without having done a full inventory of my order especially as I live in Germany. What is your experience with that ? How often have you requested parts for one order ? Thanks for any answer !

RE: [Elecraft] SWR protection
Hein, You could do that by sending commands via the KIO2 interface to the K2 - but you would have to implement a microprocessor in your amplifier to accomplish that feat. See the KIO2 Programmers Reference document. The KPA100 accomplishes similar function, but communicates to the base K2 via the AUXBUS signals - problem is that the AUXBUS signalling is Elecraft proprietary information, so using that is problematic. There is no one signal that can be used to control the K2 power. I would think it easier to provide a switch in your amplifier to shunt the input power off to a dummy load or insert an attenuator - that way all the controls reside in the amplifier itself. 73, Don W3FPR > -Original Message- > > Hello eveybody, I often use my K2 with a homebrew PA and a > homebrew tuner, I can easily take the reflectionvoltage from the > foresaid antennatuner and I should like to use that voltage to > decrease the input from the K2 to the PA if the SWR should become > to high.

[Elecraft] K2?KAT2 mod idea
I'd like to get opinions from the group on this idea: My K2 has the KAT2 which means the original antenna jack is covered up and not used. I hate waste so I've been thinking how I could use it. Couldn't I install a SPDT switch or relay so I could select either the original jack without the tuner or select the KAT2 with it's two jacks? Of course what would be ideal would be a firmware mod so instead of ant 1/2, you get 1/2/3 and have a relay going between ant 2 and the original jack. Comments welcome.

RE: [Elecraft] K2?KAT2 mod idea
Ken, Don't do that - leave the original jack covered and just forget that it is there. If you use it with the KAT2 installed, the K2 will not properly control power output (it knows the KAT2 is installed and will be looking for the power output level to come from the wattmeter in the KAT2). There may also be other problems such as impedance concerns since the KAT2 input is connected in parallel with whatever you might connect to that jack. The boot is on there for a reason, if you defeat its purpose, 'all bets are off'. 73, Don W3FPR > -Original Message- > > I'd like to get opinions from the group on this idea: > > My K2 has the KAT2 which means the original antenna jack is > covered up and > not used.

[Elecraft] KPA100 SSB Distortion
Once again, I throw myself on the mercy of the wizards of K2. Just finished KPA100, did all of the sequential tests, got the right numbers, did the alignment routines, buttoned it up and now it works just like it did before - quite well until I enage the amplifier by going to 12 watts. Then voice becomes distorted - almost unworkable. I checked rf lead from rf board to amplifier and it looks ok. I used a possibly questionable wattmeter to do power callibration. If this callibration is off, will the impact be to help me set the bias wrong? I can borrow a known-to-be reliable wattmeter and redo the settings, but I suspect something more radical is wrong. Toroid leads? mine checked out when I built it and looked ok, but??? any ideas. 73 john ferguson KI4NGH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] SSB Power
I'm a little confused about measured transmitted power when in SSB vs CW. As an example, I have an XV50 Transverter that is adjusted to produce 20 watts RF out when using the K2 'tune' control. This output is adjusted by reading 20 watts on an external power meter. The power indicator LEDs are then adjusted to read 20 watts as well. When using SSB, however, the RF out is much, much lower, maxing out at 7-8 watts PEP on the external power meter. The indicator LEDs, however, indicate 10 - 20 watts of power. I'm not certain I know how to understand what it is I'm measuring. In my mind, I think much the 20 watts RF out of a CW signal is actually carrier and of not much use. When in SSB, I want to think that I can still put out the 20 watts, only now all concentrated in one sideband. Why does the power meter fail to show the 20 watts? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Your transverter should be configured to put 20 watts out when driven at either 5 watts or 1 mW, key down in CW mode, depending upon whether you have the K60XV interface installed in your K2 and are using the RF output at the antenna connector or the K60XV connection. When your K2 is in TUNE, the power is reduced and no longer controlled by the K2's automatic power controlling system. That's so you can tune up with an ATU and the K2 won't go nuts trying to adjust its power output as the SWR changes. If you set up your transverter for 20 watts output with the K2 in TUNE, you may overdrive it in normal operation. SSB has a very low duty cycle. That is, the average power output is far, far below the peaks. You can raise the average power a bit using the K2's speech compression, but its average is still well below the peak CW level. The very brief transient peaks in your voice will hit full 20 watts out and unless your Power meter is designed to register peak RF and not average RF (like most meters) it'll show a much, much lower RF AVERAGE output even though your voice peaks are hitting 20 watts. The LED display on the transverter (and K2's RF bargraph) show the actual output, so you'll see them both flicker on voice peaks.

See, I never turn 4913 off - I just put all the controls and filters to a default setting, stow the mic and paddles then turn the AF gain down all the way. It's an old habit So, I come back to the shack to find XFIL set to 1 yet the rx audio is very narrow. Cycling through the XFIL selections, returning to #1, restores the audio.

Re: [Elecraft] SSB Power
It depends on the wattmeter. If the wattmeter had a PEP or peak-hold mode, it would show the actual peak power. Many simple meters are affected by the duty cycle of the signal, especially analog ones where ballistics come into play. There are a number of meters on the market that show peak power. One you can build is my LP-100 project which is featured on the cover of the latest QEX. You can read more about it and the simpler LP-300 kit on my website... link below. They are both digital with peak-hold, but also have very fast pseudo-analog bargraph displays that track voice peaks.

RE: [Elecraft] SSB Power
Matt, I would surmise that you are being confused by your external wattmeter. The XV50 LEDs will flash on voice peaks, but if your wattmeter is showing you average power, its indication will be much less than the peak power. This 'confusion' leads many folks to overdrive their equipment on SSB. The K2 has a good indicator in the ALC LED display. If you see the ALC indicator lighted at all, you are driving to the proper peak power. This can be observed easily on an oscilloscope - first observe the amplitude of your power setting in CW, and then switch to SSB. If the voice peaks come up to the same amplitude as you observed for the CW signal, you are achieving that same level of PEP (peak envelope power). The average power will be considerably less than the PEP power for SSB. 73, Don W3FPR > -Original Message- > > I'm a little confused about measured transmitted power when in SSB vs > CW. > > As an example, I have an XV50 Transverter that is adjusted to produce > 20 watts RF out when using the K2 'tune' control.
