[Elecraft] CE labels, band limits - no thanks!
No problem, this is familiar to me - not the first time my name is mistaken to be for a YL - and most likely not the last time either (sigh!)... :-) 73 (Mr. Kristinn Andersen, TF3KX) Julian G4ILO wrote: >On Nov 17, 2007 12:06 PM, Ian White GM3SEK wrote: >> >> Kristinn has it exactly right.

[Elecraft] CE labels, band limits - no thanks!
I have been reading some of the concerns that European amateurs seem to have about the need for CE marking, band limits., etc. Regarding the CE issue I believe that radio amateurs, who need to pass tests for their license to operate, construct and modify their own equipment, should not be required to have a CE label on their equipment. Now, I don't know if this is the final word on the issue, but I checked out the following web page of the European bureaucracy: http://ec.europa.eu/enterprise/electr_equipment/emc/directiv/text2004_108.htm. There I found the following statement for Directive 2004/108/EC on EMC, which also addresses CE labelling: "This Directive shall not apply to... radio equipment used by radio amateurs within the meaning of the Radio Regulations adopted in the framework of the Constitution and Convention of the ITU [8], unless the equipment is available commercially. Kits of components to be assembled by radio amateurs and commercial equipment modified by and for the use of radio amateurs are not regarded as commercially available equipment." I think it is very important that we amateurs don't give in on this issue. Our privileges are hard earned through our testing and licensing process, they are actually recognized in international regulations, and if the officials who execute the laws don't know better, they need to be informed and put back on track. Regarding band limits, I think we should not be required to limit our equipment there, either. Nor should we by any means ask for such limitations ourselves! By the nature of our hobby we are trusted to build our radio oscillators, amplifiers and other equipment, which technically may be able to radiate all over the spectrum, but it is our responsibility - and we should live up to that responsibility - to make sure that our emissions are within the regulations in effect in our countries. When I get around to order my K3 I will definitely not want with any CE shackles or band limitations, beyond what the designers built into the rig. 73 - Kristinn, TF3KX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2/100 or K3/10?
I own neither yet, but I have an IC746 that serves me fine for now as a 100W base rig. In this situation I am leaning towards the K2/QRP as a next rig, for the reason of portability. An excellent transceiver with a battery pack, an antenna tuner and all, ready to take along on travels or put up wherever I go. Also a very good backup rig to use at home, and running into my Acom 1000 linear I would have some 200-400W output. Then I would wait a year or two to have the K3, after the first revisions have gone through. And sell my IC746 at the same time if I still get a decent price for it. I operate mostly CW and RTTY contesting. 73 - Kristinn, TF3KX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Internal K2/K3 S-meter resolution for computer recording?
Thanks, Lyle. So, to make sure I understand this, all of the measurments (dBV and AFV) are done at the same point, at an AF level that is independent of the AF gain control. Furthermore, by turning the AGC off I will have a relatively linear relationship between the RF input level at the antenna and this AF level that is measured. That would do it for me. Just to press this further, however - I presume the K2 is limited by only providing those 10 discrete steps of "signal strength"? I don't have a K2, but it has still some appeal in being more portable (built-in battery, low RX current, smaller) for field operation and measurement. Comments, anyone? 73 - Kristinn, TF3KX >* So, the question is: How much internal resolution of the S-meter reading do *>* we have in the K2 or K3 (or other Elecraft rigs, for that matter), that *>* could be read by a computer? * *You can go one better with the K3. It has an internal dBV output which is based on a true RMS voltmeter function. This will eventually be readable by software. So, you set things up, perform an "AFV" (AF voltage, not affected by the AF Gain control, fortunately) measurement to get your reference level, then switch to dBV and see it is around 0.0 (with some bobble due to noise, etc.) Now increase or decrease the Tx output of the thing you are measuring (or swing the beam, or...) and get the result in dBV referenced to the first measurement. As long as the S/N is reasonable, you can measure over a pretty wide range of signals. Of course, you'll want to have AGC off when you make this sort of measurement so the AGC compression doesn't affect the AF voltage. And, yes, since it is an AF voltmeter, you can use this to measure insertion loss of filters, effectiveness of notch, etc. Enjoy!

[Elecraft] Internal K2/K3 S-meter resolution for computer recording?
I would like to use the K2 or the K3 occasionally as a "field strength meter", for example take the rig a couple of km/miles away from my QTH and record the signal strength from my home station. This would be useful in antenna experiments. So, the question is: How much internal resolution of the S-meter reading do we have in the K2 or K3 (or other Elecraft rigs, for that matter), that could be read by a computer? For example, I have made calibration curves for my IC746, which gives me internal S-meter readings from 0 to 255, and I have made corresponding dB charts. It appears to me that the K2 gives only figures from 0 through 10 using the BG (Bargraph Read) command, which is too coarse for such measurements. Any further info on this - for the K2 or the K3? 73 - Kristinn, TF3KX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] An external PA with the K2?
Hi: I am considering obtaining a K2 and just posted a question regarding the most useful options for QRP. Now, when using the K2 at home, particularly for contesting, I may want to run the full 100W. Instead of integrating the 100W PA "permanently" into the rig, and not having it instantly available as a QRP rig, I would rather want to have the 100W amplifier external and simply plug the K2 up to it when I am using it as a home station. So, is the 100W PA available as an external unit? Any other suggestions? I am aware of other solid state amplifiers, such as the Ameritron units, but I feel that would be an overkill. Mounting the 100W PA from Elecraft into the EC2, or something similar (keeping the QSK, as well) would be a neat solution... 73 de Kristinn, TF3KX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Suggested options with K2? Portable/contesting/CW/RTTY
Hi: I am considering obtaining a K2. My primary operating modes are CW and RTTY. Furthermore, I envision I will be using the K2 a lot for portable operation (family/business travels), but also some for contesting (again, CW and RTTY). What options do you current owners feel most valuable and I should take with the rig? To keep things simple at this point, assume that I am only interested in QRP operation for the above. 73 de Kristinn, TF3KX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
