Re: [Elecraft] K2 with 144Mhz transverter - phase noise
Martin ,for the bad results of K2+Transverter probably both of them contributed. My first try with transverter+K2 was in Marconi CW contest (November 2004).Before that i used FT1KMP and Javornik transverter. Other stations told me, that i was very noisy over a whole 2m band while on TX. At that time i was using for TX IF input ,output from TX of 10W K2 reduced with power button and adequate attenuator to bring it down to 1mW needed for transverter input.It was a horrible choice i realised. Now i am using the 1mW signal directly after first bufer (like XV144 does) and still got to test the noise with carrier on and with unmodulated signal..hope it will be ok... Maybe for someone is strange that a bit of noise is heard, but in S5 and generaly in central Europe the density of crowded band is unbelivable (several Kw stations on hilltops almost touching ich other with antennas HI HI) so the clear TX and bullet-proof RX is extremly important for contesting.

Re: [Elecraft] suggestions for EQP practice
David, I replied to this once but didn't see it show up so if it shows up twice, I apologize. I would disagree with you on your suggestion. One of the things that makes contesting a little easier (sometimes) is that the exchanges are publishes, so you know what to expect next. How many times has someone in a contest sent the exchange out of order, and that's the way you copied it into your logger, then you had to go back and retype the affected fields to get it right? And if you're really cooking in a run, sometimes you might not even realize it until you [Enter] and get some message about the info you entered was incorrect. Since the exchange has been published, most people are going to be expecting the letter K as the first character in the rig portion of the exchange for most of their qso's. Changing that to a 2 followed by a slash, etc etc is just going to add confusion. Having to resend the exchange just one time is going to offset a lot of the time saved by not sending a K. And that's not even considering the folks who may not be on this reflector and never seeing your post. Having said all that, hope to see you on the air.

RE: [Elecraft] 4044# dead
Ian, It is difficult to say where the problem might be when all I really know is 'it is broken'. The best place to start is to determine what does work. Do you have voltages anywhere (check input and output of the regulators on the control board)? Are the voltage readings good (compare with the chart in the back of the K2 manual). If the menu works, enter CAL FCTR and use the counter probe to see if you have VFO and BFO oscillators running? Is their frequency correct? Continue with this process until you can narrow the field of potential places to look for the failure. 73, Don W3FPR -Original Message- Hi all, #4044 has died.

[Elecraft] The Spirit of this reflector
I know this is a bit long but it so represents the spirit of this reflector, I just had to pass it along. Enjoy. As one of Jeff's Elmers I know I walk a little taller after reading this. 73s Jim, W4ATK Find the Golden Thread in BARC By Jeff Drew, N4JDU There is a value to club membership that every new member needs to use. There is no charge, but the end results can not be measured. I have only been a ham for about a year but I have discovered from the Elmers ( i.e. senior hams) a sincere dedication to the future of ham radio and to us, he younger hams. I used to ask, why all this attention to younger hams? There is plenty of literature available to all of us, but nothing is better than actual one on one contact by an Elmer. We are fortunate to have in our club a large number of Elmers. I strongly recommend that any new ham find three or more Elmers to share the fine points of ham radio with you. I guarantee they will do it! Heres why: These hams have seen the effects of time on our hobby. Some good, some bad. They know that if we dont use it, we lose it! They realize that the bands associated with Amateur Radio are constantly being sought after by commercial endeavors. Currently, the attack is with access to broadband power lines (BPL). There are many such quests for our band space. My point is that the band allocation to ham radio is always politically un-stable. Technology plays an important factor here for both interests. The Elmers want to se the art form preserved. Their theory is that a certain perpetuation plan be put in place. Heres what I think it is: · Be available to young hams for questions and answers. · Help them in their particular interests. (I.e. Phone, Rtty, PSK, CW, Satellite, EME etc.) · Encourage new hams to explore the broad characteristics of the amateur radio. · Share your experience with new hams that want to learn. There may be more un-published directives from the Elmers, but I have seen their determination to preserve the hobby. From my point of view, they see the future of ham radio in us! It is up to us to put forth the effort to locate an Elmer to counsel us as we embark upon this vast sea of radio. Nothing could be a better resource than having the knowledge of an Elmer. It is the golden thread in our organization. Let s use it before we lose it! Think about how powerful we would all be if we each had an Elmer who passed on his experience with us! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] ECN/30 report
Someone once wisely suggested picking a non-cardinal frequency for the ECN - and I think I really need to heed that advice next week - so watch for an odd frequency (e.g. 10118.7) for the net next week. Running QRP-10W has it's disadvantages - especially when a DX station (TO7K/TO7C?) starts calling on top of your net, and then you try to QSY up and wind up in the middle of the DXers trying to call the DX. The net started off quite nicely with AI4BJ/Mark in KY (K2 #3862 - RST 579). Shortly after that, the DX station popped up. My first attempt to move involved a QSY up to 10115.5 - then I started hearing the DXers calling. Then I tried to announce another QSY to 10114.5. So, if you were looking for the net and having a tough time locating it, I finally ended up on 10114.5, and had no more check-ins after calling for about 10-15 minutes. I then decided to make the best of the evening, and tried calling CQ - and immediately was greeted by two replies. The stronger signal was W4ZLU/Bill in AL. We had a very solid path since I was 589 (and he was s9+10dB at 50W). Tuning around shortly after my contact, I did hear W4ATK (with N2KZ) mentioning that he had a K2 at 10W - coincidentally, on 10115 - so, I'm sorry if you were looking for the ECN. The YL/'pre-Master Control' here has given me the okay to play radio while she sleeps in Saturday morning - so I'm looking forward to working all of those Elecraft S/N's out there. 73, Daniel AA0NI Oklahoma City ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] amp keying question
Hello Dwight, The External PA Key jack does not source current to drive a relay; rather, it sinks current from the relay, so you essentially connect your relay between the +12 volt source and the External PA Key jack. So, if what you're asking, is how to connect an external relay with a 12 volt coil to the External PA Key jack on the KPA100, then... - If you're using a 12 volt power supply separate from the one powering either your K2 or or KPA100, be sure that the external power supply ground is also connected to the KPA100 ground. - Connect one lead of your relay to the (+) lead of your 12 volt supply through an in-line fuse holder, containing a 1/2 amp or 1 amp fuse. - Connect the other lead of your relay to the External PA Key jack center pin on the KPA100. - I'd recommend that you also place a diode such as a 1N4001 across the relay coil to suppress inverse EMF when the relay is de-engergized. This diode should be connected such that the cathode end of the diode (end with the band on it) is connected to the relay coil connection which goes to the (+) positive 12 volt line via the fuseholder, and the anode end of the diode (end *without* the band) should be connected to the end of the coil which you connected to the KPA100 External PA Key jack. (Do NOT reverse the connection of this diode; Q9 in the KPA100 will not be appreciative, although your in-line fuse will protect it) That should do it. When you transmit, your external relay will be energized, and you should be able to key your heathkit amplifier via the relay contacts. 73, Dale WA8SRA Dwight wrote: So, having tried and not succeeded, does anyone have a circuit suggestion to tie in with the External PA Key jack on the kpa100?

[Elecraft] Long wire connection
Hi Lee, Something that I have used in the pass was a PL259 fitted with a 6-32 (I think that was the size) brass threaded rod or a long screw with the head removed. Solder it to the center pin, close off the ground holes with tape and fill the body with epoxy. This leaves you with a threaded portion to attach any type of wire. You can either use a hose clamp or solder a wire to the end of the shell for ground. The only problem I can see is a lot of RF floating around in the shack. I think you'd be better off running coax of the shack to the long wire and attach your counterpoise at that junction. I'd still like to have a remote version of the KAT100 ala SGC... Good luck!

Re: [Elecraft] filter alignment question
W3FPR - Don Wilhelm wrote: If the tone pitch change is 20 Hz or less it is because of the quantizing error in the K2 and nothing can be done about it. The K2 firmware works to preserve the pitch no matter where the filters are set as long as the signal is anywhere within the filter passband. Well, something CAN be done about it, if you don't mind changing the filter bandwidth slightly. For example, suppose that you have set a filter to 400 Hz bandwidth and located the BFO so that the signal is centered in the filter, and suppose that the result is that the pitch of the centered signal comes out 10 Hz. high. Just change the bandwidth to 420 (or 380) Hz., readjust the BFO and let the K2's magic algorithm do its work. Chances are it will come out on pitch.

Re: [Elecraft] K1 KFL1-2 80m question C78/RFC8
Tom Juelich wrote: I am just wondering what for are C78 and RFC8 on the RF board? They are only supplied with the 80m kit. I don't remember what Gary Surrency at Elecraft said about the problems that were found on 80m that required these components. You could email him directly. I just went ahead and installed them in my early K1 (which did NOT have pads for C78 or holes for RFC8) when I built a board with 80m. Can anyone tell me the value of C78 and RFC8? C78 = 22 uF, RFC8 = 100 uH I think it would be best for Elecraft to supply these two components standard with the basic kit so that all K1s would have them. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] TNX FER..I/O construction
OK, I am cutting thru this I/O kit like butter. Should have it done in another hour.. I am very interested in what type of software is available. Of course like everybody else, I want the rig on the laptop for control and display. I am ultra interested in hidden menues or CPU instruction codes. Would it nice if the EEPROM could be converted to open code. Then compile it on visual basic. Get the k2 to do things It did not know it could do. My main idea would have an algorythm that accuratly controls the bfo. Also the ability to of shift certain other oscillator freqs and amp gains. With this one might be able to software emulate PBT or Vpbt, notch. Of course you could use a parametric mic equilizer. Everthin would go back to normal mode. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
