[Elecraft] Looking for KFL1-2 or KFL1-4 built or unbuilt
Hi to all the subscribers A good friend of mine bought recently an unbuilt K1 kit but unfortunately missing some relevant bits. The kit had the bare K1 enclosure and, unfortunately the band board module was missing. After doing the inventory, thr RF board and front panel board components were all there. I wonder if someone in this list might have a 2 or 4 bans board built or unbuilt surplus to his needs or even a bare pcb. Elecraft still supplies the components for 30, 40 and 80m bands. If someone would have an extra front panel, it would be perfect. I wonder if the Gerber files for the 2 and 4 bands pcbs are available or can be obtained somewhere. Thanks in advance for the replies. 72/73 de Vicenç, EA3ADV __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] OT/ Spare MPSW01
Hello to all the list First of all let me apologise for using some bandwidth on the reflector. Although this is not really an Elecraft topic in itself, I decided to post it because I thought it had to do with our common hobby. While troubleshooting a Ten Tec 1208 transverter last weekend, I found that the PA bias transistor Q14 was dead. It is a MPSW01. I was trying to find a pin to pin equivalent in order to avoid playing with the legs (not too much room to play on the PCB) and I was unable. I visited the 2 main electronic component shops in my area and unfortunately I was unable to find a replacement. I wonder if perhaps a member of this homebrewers list may have a spare MPSW01 in the junkbox and would be willing to part with it, or perhaps can advice where to buy a couple of them. I obviously would pay for the part and the mailing to Barcelona, Spain. (I guess that mailing cost will be even higher than the component itself). Many thanks in advance for your kind help and advice Best 72 de Vicens, EA3ADV K2 # 3279 and 4726 K1 # 1445 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Real DX in 40m
Dear all I am still a bit nervous and excited but I wanted to report good news to the list. A few minutes ago I worked VK6BN in Swan View running 4W out from my K2 an using just a simple OCF dipole (Fritzel FD3) which was hung on Sunday with the help of Santi, EA3CKX (K2 # 1724) and Quim, EA3AEK. The band was quite crowded but Alan answered immediately with QRP??. Excellent ears and skills by his side. Tonight I will for sure have a nice sleep.

[Elecraft] 2xK2 QRP QSO
Hello to all I am happy to be able to report that I managed to work W4FOA on 20m on the 5th of January. Although band conditions were not good we finally exchanged all the infos to fulfil the 2xK2 QRP QSO. Tony was running 5W into a 3 element Yagi while I was running 4W into a 8m vertical marine whip fed with 12m of heavy duty 300 Ohm ribbon to a 4.1 balun and Z11 atu. Thanks to the skills of Tony featuring really fine ears, my low signal was readable at his end.

[Elecraft] Another limited space antenna advice
Dear all After reading the last posts with different proposals to solve the antenna setup in a limited space scenario of one of the list members I decided to ask as well for advice. I am quite sure that I will get good ideas that perhaps will change my mind. The scenario and past experiences are as follows: Location: small village in the mountains (about 4000feet high) and with strong wind storms from time to time (a wind which is called right here tramuntana) Past experiences: I had to disassemble 2 consecutive vertical antennas (CC R7000 and R7) that were about to break (no possibility to guy them). The lower element was absolutely bent. With both verticals I enjoyed quite a lot of DX just running 2-3 watts (I only operate QRP)and nice chats on 40m with local stations although in my log there are a couple of 2xQRP contacts on that band with USA stations. Anyway, after disassembling the R7, I started to think about a feasible alternative to be able to operate from the weekend QTH in Pardines. My final thoughts that I would like to share with the list members asking for advice and recommendations are as follows. Imagine the roof of the small house as a trapezoidal shape (Top view).The lower side of the trapezoid measures 25,4 feet, the left side (almost vertical)about 15 feet, the right side (almost vertical as well)about 23,3 feet and finally the top side of this trapezoid sloping from the right to the left is about 25,6 feet. On the top left hand corner of the trapezoid there is a tower base with small tower element (just 5 feet high) which acts as a support for a rugged mast where in the past were settled the verticals. The path for the feedlines to the attic is just near the base of the tower. I have currently 2 RG-214 feedlines about 40 feet long. One is used with a 6m GP and the other one is free. Not too much room for other cables. After thinking for a while about alternatives I ended with 2 complementary antennas. On one hand a fiberglass vertical marine antenna about 26 feet able to stand the strong winds of the zone, with an automatic antenna tuner just at the base (I recently built an LDG QRP tuner inside a waterproof case). The main drawback would be that according to the situation of the house I would be able to arrange some radials only to the right of the radiator and with a maximum angle between them of around 120 degrees. Although I am not able to simulate the behaviour, I believe that this antenna would be useful to work with reasonable performance on 40, 30 and 20m, but the radiation angle above those bands would be really a compromise(??). The complementary antenna I thought about was an horizontal pseudo-rectangular loop with an overall length about 75 feet and about 9,8 feet above the roof. The horizontal loop would be fed on the top left corner with about 50 feet of 300 Ohm slotted ribbon to a Z-11 tuner in the shack. According to the literature I have been reading, it seems that the loop would be useful on 20 and above with probably low radiation angles on the upper bands (10,12 and 15). When analysing how to feed the vertical marine whip I thought about 2 other possibilities. The first one was to throw away the remote atu and just feed the vertical and radials with 300 Ohm ribbon. An intermediate solution would be to feed the vertical and radials with about 13-14 feet of 300 Ohm ribbon to the remote atu but inside the attic, just at the point where the feed lines enter the attic.(I would arrange another 50 Ohm feedline inside the attic). With this approach the outer RG-214 feedline would be free for another antenna. One of the main constraints is that the feedlines path to the attic is really narrow and I have still to check if the control cable for the remote ATU will fit and travel free inside the plastic tube going from outside to inside.(that is why I thought about the alternative of using 300 Ohm ribbon). I hope that the scenario will be clear and would appreciate any comments or suggestions that for sure will improve the proposed setup. I must apologise for being so long with the description and to be using such a huge bandwidth of a list devoted to our little gems (KX1, K1 and K2). I hope that my request will be helpful as well to others facing similar limited space constraints, but in order to avoid too much traffic regarding this matter on the list, I would appreciate your comments or suggestions off the list unless the list moderator feels that the information and feedback will be helpful to other list members. Many thanks in advance for your patience, kind cooperation and help.

[Elecraft] K2 #4990
Hello all Yesterday I started building my third K2. This one obviously not for me but for a friend who was very excited to own this little gem. I have just built the control board and front panel board and hope to undertake alignment and test part I this afternoon. Until now and like with the other K2s everything going flawless and with no troubles. I would like to finish this K2 just before my summer holidays to allow Xavier, EA3FTJ, to enjoy it as soon as possible. I am sure he will be delighted with it. K2 #4990 will have as options the KNB2 and KAF2 as far as Xavier is 100% CW. I adviced him to take only those options and try the basic K2 running 10 to 15W (in any case he would be able to upgrade to the K2/100 at any moment). I will let you know about the progress.

[Elecraft] K2 #4726 alive!!
Hi o all the list As expected, K2 #4726 passed alignment and test part III without troubles. As far as I operate 100% QRP I wound T4 for better efficiency at 5W (2:2 ratio). One of the first contacts on 40m was with Fred, EA5/DL4ZBY, who was also with a K2 running 10W to a G5RV antenna. I was running 4W to a compromise antenna (random vertical square loop around the front façade of the building feeding a 4:1 balun to a Z11 atu). I hope in a few weeks I will erect a 23' marine whip with a LDG QRP tuner in a waterproof case at the antenna base with a set of resonant radials. The fact is that I have no room for wire antennas and the vertical whip is a feasible alternative basically because of the strong winds in that area (I already had to disassemble a R7000 and R7 because they were absolutely bent by the strong wind storms). I hope also to be able to refurbish the antenna setup in my home QTH in Barcelona to be able to put strong QRP sigs with my 2 element delta loop (Lightning Bolt) from 10 to 20m and my 102' doublet dipole with open line feeders, 4:1 balun and again Z11 atu. I will probably try as well a windom FD3 (I do not have room for the FD4). Next weekend I will test and install the K2 accessories I built: KSB2, NB2 and AF2. I am planning as well to add the digital modes interface designed by Pauli, EA3BLQ. I guess that PSK31 is a suitable mode to operate in QRP.

[Elecraft] RV: K2 assembly page 52

In the current manual to build S/N 4726 it instructs to install 3 components on the bottom of the board (C91, RFC15 and C88). I remember that when I build S/N 3279 there were only 2 components, C91 and RFC15. As far as I understood from the information about the additions on the hardware side, those were mainly related to the CW shaping envelope and also the 2 diodes D40 and D41 to prevent RX overloading. I wonder if I should have to add the 68pF capacitor C88 to the bottom side of the board on my S/N 3279. Many thanks in advance for your reply AND 72 Vicens, EA3ADV P.S: Hope to perform alignment and test part II this evening. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 paint
Hi o all This morning I ordered the repair paint from Elecraft. I was not aware of this nice addition to the parts and mod kits page but thanks to Mick, M1MDG, I found the solution to my problem (I hope I will need it only for the light scratch on the bottom cover, Hi). I really believe that my mistake was as a result of the excitement to fire up the rig. Fortunately everything went well and K2 #4726 passed alignment and test part I with any trouble. I am just waiting for the weekend to go on building. I will let you know. What a big pleasure to fire the K2 for the first time. Lisa Jones at Elecraft was, as always, absolutely kind and helpful.

[Elecraft] K2 paint
Hello to the group Just a few minutes ago I finished alignment and test part I for my brand new K2 with S/N 4726. Everything went right first time with no trouble at all. When assembling the tilt stand to the bottom cover while I was doing pressure to set the second oval foot the screw slipped laterally and lightly scratched just near the foot. Although this is not a visible part I would like to have the whole rig in mint condition and that is why I would appreciate if someone could advice about where to get a bit of paint to repair this scratch. Perhaps it is a standard paint for automobile or airplane models and I am able to find it here in Barcelona. I am sorry about taking some bandwidth of the reflector and many thanks in advance for your advice. 72 de Vicens, EA3ADV K2 # 3279 K1 # 1445 Building K2 # 4726 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 S/N 3279 alive
Hi to all the list I am happy to let you know that K2 #3279 is up and running. Some of you may think what is absolutely true. I had the kit on my bench for quite a while with no time to build, but finally I found a gap during last Christmas holidays. I was delighted with this building experience and realising how step by step the rig was coming to life. I took my time and spent about 35 hours to build the basic K2 together with the NB2, SSB board and Audio filter board. Everything worked first time although I made two minor mistakes. I swapped R34 and R43 on the RF board (perhaps dyslexia??) but fortunately this error did not produce an undesirable effect on the rig. The second mistake I would like to point out because it was a bit more tricky in terms of solving the problem is that I swapped 2 resistor networks in the SSB board, namely RP5 and RP3, (in this case the fault was probably because of the excitement to have the whole thing working). Just in case someone else makes the same mistake, the effect of swapping those 2 resistor packs is that the power output in CW does not go over lets say 4 to 5 Watts with independence of the power setting with the power pot . I would advice everybody to double check values as Elecraft advices in the manual (and not get so excited as I was) because unsoldering a resistor pack is a tricky issue. I managed with solder wick and quite a lot of patience. Next step here will be adding the digital modes interface designed by Pauli, EA3BLQ. I have been in touch with him and hope to have it in a very short time. Another personal challenge is to include the K2 in the EA Amateur license which is not a simple matter due to the fact that Spanish laws are really very restrictive regarding some issues. For instance, one of the main topics is that a rig must only be able to transmit inside the band limits allowed by the law. I contacted Wayne, N6KR, asking for the possibility to programm an I/O controller with the EA band limits and he accepted. I would like to express how pleased I am with the support and assistance provided by all the Elecraft crew. All they are really focused on customers. This is at least my perception and feeling.
