Re: [Elecraft] Elecraft CW Net Report for June 6th, 2005
Morning Kevin, Was on at 0230Z or thereabouts and heard Tom N0SS for sure, RST 229 through very strong Russian SSB QRM off the back. The Russians were not amused by my CW, don't blame them, but fortunately I know one of them reasonably well (he runs 2kW into a 4 element 40m monobander at 30m plus up), so I might live. Other QRM also, and conditions to the USA not good at all. Sorry to report that no other ECN check-ins heard this time. 73, Geoff GM4ESD - Original Message - From: Kevin Rock [EMAIL PROTECTED] To: Elecraft elecraft@mailman.qth.net Sent: Monday, June 06, 2005 4:45 AM Subject: [Elecraft] Elecraft CW Net Report for June 6th, 2005 Good Evening Folks, Now that the ringing in my ears has cease somewhat it is time to make a few apologies.

[Elecraft] Low power on 20m using the KPA100 option
Dear all, last weekend I finished the KPA100 option, which is causing a little problem. Everything Is running well except power on 20m, where I just reach 50 Watts. The QRP output is not affected, so I am quite shure that the RF path to the antenna through the LPF is ok. Just to be shure I have checked all inductivities and capacities of the 20m filter. They are ok including the used core types of the inductivities. Somehow I am getting the impression, that on 20m the PA doesn't get sufficient driver Power. My signal reports on 20m have been ok, except the missing 50Watt. This issue drives me realy crasy, because everything else is working ufb. Any suggestions? vy 73 de Martin, DL6KMR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Re: KPA100 in EC2 question - any reverse steps?
My question is this. If I follow the KAP100 manual will I have to reverse any of the steps from this point on if I will be using the amp externally? Good advice on the reflector seems to be to build the amp, remove the current K2 top with the battery and AT etc and check out all amp functions as if the final product would be a K2/100. I have (this is from memory, so pls check): - installed an IC socket instead of the RS232 driver, and left the driver chip out. The KPA100 can't do any RS232 conversion in this config, and letting the chip out makes cabling a little easier. - Left out the speaker and replaced it with a piece of black plastic, again, no need, and I'm saving the LSP as I'm considering putting the LSP in front of the KAT/KPA box; the LED display isn't very informative and I'd like to see what sound I get with speaker in front. (Eric says won't be good and I haven't tried). - Not installed the DB9 connector on the KAT100. The KAT100/KPA100 box only needs one DB9 connector, the other connector enclosure hole is filled up with a blind panel. - The KAT100 gets it's AUXbus signalling from the flatcable between KPA100 and KAT100. Should you ever want to install the KPA100 in the K2 itself, then you can just socket the RS232 chip. The KAT100 is useless w/o KPA100 counterpart, but in my case I've *never* felt a need to transplant the KPA100; I don't even have the right shielding for it.

AW: [Elecraft] Low power on 20m using the KPA100 option
Hallo Vic,
Many thanks for the info. I thnink I am dealing with issue number 2).
By now I am quite shure that the driver part of KPA100 option is
draining power on 20/30m avoiding the last stage to reach full
Power.
I am going to ask Gary.

Martin

Re: [Elecraft] Finally managed QNI on ECN on 40m
Hi Rich: I heard you just fine here in Amarillo this evening. This was the first time I checked in also. I just finished a home brew 1/4 10m vertical this afternoon. The tuner in my 1000mp(running about 10 watts out) tuned it just fine on 40m. Tom was S9+10 but he said I had some QSB on my signal. Signals here were often pretty marginal... not only due to QSB but also due to some pretty severe QRN... nasty stuff... I apologize to ANYONE I might have missed... at times I could hear a signal I though might have been calling, but could never pull any intelligence out of the noise, and when I'd ask for a possible relay, I'd generally just hear more noise... sorry. Tom, what type of antenna are you running? You were very loud. Running a K2/100 at about 90W output into an inverted vee with the apex at 72', running N-S, so you were generally off the ends of the antenna. I wonder if 40m was going long early, hence my weak signal. Undoubtedly... happens just about every year this time G. 73, Tom ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] k2 s/n 4886, cap C45, page 65
I just looked at a K2 RF Board and it leads me to think you are trying to place C45 in the wrong spot - there are only 2 holes where C45 is to be inserted - the position is to the rear of the board from the 'C45' label and right next to the relay. Yes, spread the legs of the small capacitor to fit the hole spacing. That action is necessary for several of the capacitors in the bandpass filter area. 73, Don W3FPR -Original Message- Hi: Similar to cap C6 on page 57, do I install cap C45 in the outer two of the three holes?

[Elecraft] KX1 Question
I finished my KX1 and it seems to be operating just fine, but I've notice something I've not noticed on my K2, or on my ham receivers for that matter. If I insert a long random length wire into the KX1 I don't hear receive too many signals; advance or retarding the RF gain has little audible effect in the headphones. But, when I also attach a wire to the outside of the BNC connector and then to a ground, the receiver comes alive with signals. At first, I thought this had something to do with running the unit off batteries vice my Astron power supply - till I realized (by turning off the Astron but leaving the KX1 plugged into the power supply, which is grounded; then by disconnecting the PS but connecting a ground wire to the outside of the BNC connector), that its just having the unit attached to some kind of ground. So, does this sound normal or have I perhaps miswired something? (Must be a noncritical mistake if I did, cause every function on the KX1 seems to work FB.) Now to build the 30m module and the ATU ... Thanks! Paul, N6LQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] KX1 Question
Paul, This is normal. You need two wires for your antenna. If you have the antenna tuner option, you can use the Elecraft suggestion of the following: hook a 16, 24, or 33ft wire to the ground side for 20/30/40, and a 24-28ft wire to the center conductor. The Pomona BNC to binding post adapter makes this convenientthere is a part number in the manual. Then tie a hex nut to the hot wire and throw it in a tree and put the other wire on the ground. (You may get away with shorter wires for ground, but these are convenient sizes for putting in the air as well...putting both wires in a tree works, too.) Almost any wire will do, but Teflon-coated silver plated wire is often available from surplus places, and is excellent. Or try thewireman.com for other nice wire. 73, Leigh/WA5ZNU.
