[Elecraft] Blown R58 relpaced, still no power out, does anyone have any hints?
Hi Guys, A few weeks ago I managed to induce a fault into my K2 by transmitting into no load when testing the top band option. I found that R58, the 180 ohm, half watt resitior at the far end of T4 had been damaged and had a value of 4 ohms. So I replaced it and reassembled the K2 and I still have no power out. Before I remove all of the options (ATU, Top Band and SB) and take it back to basics, which will take time will not have for a month or so, can anyone suggest other components I might check.everything else seemed ok including the PA Transistors.. Also, what is the purpose of R58? Sorry guys but i am just not as clever as the rest of you, I do software for a living, not electronics...but I am learning..

[Elecraft] OT Does anyone have a servicing manual for a weller DS 801
Hi Guys, I was given a Weller DS801 desoldering station a while back which has never worked but looks brand new. . It sucks fine (over here in the motherland this does not mean it is bad) but the tip does not come up to temperature. At a guess the element in the iron has gone or the thermoregulator inside the base unit is faulty..I wonder if any of you kind folk might have a servicing manual i might consult..ir some experience of the DS801. As this is off topic i wonder if you would reply off list 73 de Steve G0XAR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] PC BOARD DRILL BITS
Tom, You are dead right about the fragility of the bits. I was lucky enough to pick up a couple of boxes of bits at Dayton a few years back, 50 bits per box, $5 per box, the guy had loads, they were new too, guess I was lucky.

[Elecraft] KSB2 Missing parts
Hi, I have just checked my inventory for the KSB2 and seem to be short of all of the components for mounting on the front panel board, i.e. : - P1, c4-c8,q3,rp3,rbias and R13, It seems to me that the parts must all have been in 1 envelope and this was omitted from my kit. Before I contact Elecraft for replacements I wonder if someone could confirm this so I can check the shack to see if the envelope has been stolen by the underpants gnomes.

[Elecraft] Stupid Englishman confesses all
My only excuse is that my construction time is limited and it must have been 9 months or so since i soldered the missing parts on the control board and forgot to tick them off in the KSB2 manualas i am only 53 does this count as a senior moment?. Thanks to Don for pointing me in the right direction. When will I ever learn to follow instructions?

[Elecraft] OT K0BRA Active Antennas AMRAD
Greetings from England, I wonder if anyone can help me get access to the AMRAD Website. I am about to start building the K0BRA Active RX Antenna as featured in the Sept 2001 QST and I am interested in getting the documentation at : - www.amrad.org/projects/lf however Firefox and MS Explorer cannot get access, the former thinks I should be using HTTPS, the latter just shows a blank page. Of course if those fine and talented Engineers at Elecraft produced a kit for an active antenna I would not have to bother using the AMRAD design(Hint hint). In all seriousness with the number of SWLs and antenna restrictions around there could be a big market for just such a kit.I want mine to do some listening with what I am away on business trips...

Hi all It was a feindish trick...the URL in the QST article does not exist..This one however does https://www.amrad.org/projects/lf/ thanks for the help.

[Elecraft] Friedrichshafen
Hi all, It seems to me that a gathering at Friedrichshafen for us Elecrafters might be a good idea. I'll be attending with Jan G0BBL and Alan M0PUB and all of us have built K2s..we are staying in Lindau and hopefully will operate portable from Austria, Switzerland and Germany whilst we are therepossibly Maritime Mobile from the ferry to Switzerland...if Maritime is the right word... I have done two Dayton/FDIM trips..you will not be disappointed. Regards, Steve G0XAR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] k2, s/n 5171, alignment and test, part iii
Hi, Check the number of turns on the toroids for the 80 M band pass filter. I had a similar problem on 40 M because I had 1 turn too many on one of the toroids.

[Elecraft] K2 number 3354 lives
Hi Everybody, My K2 sn 3354 livesthank you to everyone on the reflector for helping me debug the couple of problems I have had along the way. If I may make a comment about Page 74 in the manual TX alignment - I found it curious that once the RX had been set up one has to repeat the same procedure for TX alignment. In my case when aligning the TX for 20 Meters the output power went haywire after I set C21 and C23 to their mid point settings and started adjusting L8 and L9. To cut a long story short I went back to the RX pre alignment stage and set C21 and C23, L8 and L9 for maximum signal strength. Then I returned to Tx Alignment without changing the settings...the tx power was stable at 2 watts...I then checked all of the other bands for tx power without altering the settings from Rx and all seems to be well...i.e 2 watts on the POWER control, 2 watts out...on the Motorola test set. So I do not intend to carry out any TX alignment...unless someone can explain why I should. BTW on all bands the MDS is in excess of the quoted -135DBm - assuming the calibration on the Motorola test set is good I get readable signals at -137 dBm. Lastly I would just like to thank everyone at Elecraft for such a fine kit. It has been really been a lot of fun building the K2 and I have learned a lot along the waythanks guysnow to start work on the option kitsThe K2 is in the shack tuned in to a contest on 40 meters...and coping very well...I wish my morse was up to it... 73 Steve G0XAR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] TX current on the Elecraft K2
Gentlefolk, I could do with some advice. I am at Page 72 in the K2 MANUAL aligning the TX for 40 Meters. At 5 watts output the current drain is supposed to be 1.3-1.6 amps. The book says if it is *much* higher than this, or the Voltage drops more that 1 Volt I may have a problem with the TX, load or PSU. The figures I get are: - Tx Off...13.8 Volts 200ma Tx on...13.1 Volts 2.16 amps 5 watts out according to the K2 internal meter, 6.1 watts out according to Motorola R200D comms analyserwhich contains the dummy load...the PSU is a large Palstar 30 ampere gizmo thus oodles of spare umph. Setting the power at 10 watts I get the following. Tx on 13.0 volts, - High Current warning then 2.44 amps 10 watts out according to the K2, 7.87 watts according to the R200D, the manual says if the current is *much* higher than 2 amps see troubleshooting. The R200D tells me the output frequency is very stable...and after a short warm up that the power out of the K2 is not fluctuating .and I am assuming that its dummy load is good...the interconnecting lead looks fine though it is rather (i.e. 10 meters) long.. And I am using a bnc to ntype adaptor at the R200D end. The K2 current meter tells me that after about 30 seconds the current is stable at the values I have quoted above... So the 64,000$ (£37,647) question is..do I have a problem or not...normally I would go through the trouble shooting stuff but the shack is as cold as heck at the moment and I have some other things to do..and M0PUB wants a sked when its finished and I have the ATU, Sideband and 160 meter options to build and the battery option and I want to get it all finished in time for the winter sports.

[Elecraft] Re: TX current on the Elecraft K2
Hi Worshipful members of the order of Elecraft, The awsome power (haha) of the list, in the shape of Don W3FPR pointed me in the right direction. My mistake was to wind L26 with 13 turns instead of 12. Now I have corrected my blunder we have : - 10 Watts, 13.1 volts and 2.36 amps - no overcurrent warning...RTFM as they say I shall assume all is well...now to pre align the rx for the other bands Kind regards Steve G0XAR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
