[Elecraft] N-gen

I built the N-gen and the noise does not increase like it is supposed to. I re-heated the joints, checked for proper part placements but it still doesn't work properly--- until I hold my finger across R1 and R5 at the same time, then the noise increases. Anyone else run into this problem ? An

RE: [Elecraft] KPA100 - L15 Inductor

You are correct David. You should have checked off a step where you confirm that nothing is installed in the space on the PCB for L15. (See page 21 of the Rev. D manual, left column) Also it's listed again as a part that is not installed on page 41 just before you "button up" the amp. Wayne lef

I would be interested in seeing the pics. I purchased a couple of bead wire spools. It is a cool idea. I am planning on taking my K1 camping soon, and might give it a try. Pete > > From: "Edward R. Breneiser" <[EMAIL PROTECTED]> > Date: 2006/10/10 Tue PM 06:45:08 CDT > To: , <[EMAIL PROTECTED]>,

[Elecraft] WA3WSJ: Bead-Wire Antenna in the Field

Hello all, I hiked up to Pulpit Rock about a two-mile hike straight up the mountain for the PBMME. After setting up my KX1 and my Bead-Wire Antenna, I called CQ and WA8REI came back to me from MI! He gave me a 579 report and he was strong as well. I worked more stations after him including an IK2

RE: [Elecraft] KPA100 - L15 Inductor

David, Manual Rev D is the latest, and yes, if you look at page 21 and page 41 of the KPA100 manual, you should see that C82, L15 and R12 positions are not populated. You may have a use for that extra core someday, but 8 are sufficient in the KPA100 - you just got an extra one. 73, Don W3FPR

[Elecraft] KPA100 - L15 Inductor

Hi All, Just a quick query!! I'm putting together a KPA100, and want to just confirm that the outline for Inductor L15 on the circuit board should be left empty. I can't find any reference to L15 in the manual (Revision D), but when I've looked at the online manual to search for the part, it i

Don, Thanks very much for your reply. Of course it is working OK at present. I will make more careful notes of the symptoms next time it occurs and report back. Simon - Original Message - From: "Don Wilhelm" <[EMAIL PROTECTED]> To: "Simon & Liz Watts" <[EMAIL PROTECTED]>; Sent:

Re: [Elecraft] Icom 735 inquiry

Bob, I do not have any experience with an IC-735, but I did take on a IC-751 project a couple of years ago. Icom has a fairly good web site where you should be able to download docs, schematics, etc. Also, I called them and for 25 bucks, they sent me a copy of the entire 751 doc library, includi

Re: [Elecraft] Noise Blanker

I is my experience that the K2 Noise Blanker is quite effective on certain types of impulse noise, while of little help on others, i.e., it is quite dependent on the characteristics of the noise. For atmospheric noise, the noise reduction function of the KDSP2 works better than anything

Re: [Elecraft] Common mode current

If you're talking about common mode currents in a low gain receive antenna like a Pennant, K9AY loop, EWE, etc., common mode currents are of great concern because any signal picked up by the coax is very significant compared to the desired signal picked up by the antenna. Common mode currents are

RE: [Elecraft] Icom 735 inquiry

I had an IC735. On paper it sure looked like a great rig. In practice I found the sound of the rig to be irritating. Background noise was harsh and spiky for lack of a better word. Recovered audio left me wanting to turn the rig off. GC receive, which I though would be a great thing, turned ou

[Elecraft] 40M DX and DSP

I am very impressed with the K2 RCVR and DSP. I didn't really expect much DX on 40M but usually around 11:30 pm (0330 UTC) and around 7005 KHz lots of European stations from Russia, Bulgaria, Ukraine to France, Sweden, Germany. But last night I heard 9J2BO, Brian, in Zambia. No QSO but i

Re: [Elecraft] Noise Blanker

NB removes man-made noise, NOT atmospheric noise. Filters DO NOT remove man made noise. Nor do they remove atmospheric noise. As I wrote, they give the appearance the noise is gone, when turned on to narrow the bandwith. That's why you turn up the volume a bit to compensate. The filter's j

Re: [Elecraft] Icom 735 inquiry

With my last IC-735, I recall I did inquire to ICOM AMERICA, State of Washington, about their replacing the RAM MEMORY BATTERY in my IC-735. If I'm not mistaken, they said they no longer carry it. But there are several outfits who sell memory backup products, for the IC-735. I forget now, but Ic

Re: [Elecraft] Noise Blanker

I'm arriving at this conversation a bit late, but let me ask this question. I have a relatively newly assembled K-2, working perfectly as far as I can tell. I have the KNB2 assembled and ready to install. After reading these posts, I'm wondering if I should bother to do it. I find, as Ron said,

Hi Steve, Question: How do you go about detecting common mode current on the outside braid of your co-axial cable and then measuring or quantifying the amount thereof? You need a shield current meter. They're easy enough to build: http://w8ji.com/building_a_current_meter.htm And cheap eno
