[Elecraft] Homebrew un-mod kit

Hi to all guys of like to experiment in their K2, I was inspired by un-mod kit that was posted on the reflector a few weeks ago I did mine. So when I want to remove a module to isolate a problem, or simply to make more space to work in the K2 when trying some experimentation, simply rep

The L network tuner has one less lossy reactive component, (coil or cap). It also has an unambiguous tune up for optimum power transfer. Ie, only one setting of the variable components gives the lowest loss transfer of power. In a Tee tuner, there are three adjustable parts, and two settings fo

Another answer for Darrell, is that a balun is designed to see equal antenna halves either side of it. (on its balanced side). There is no advantage to using one on an end fed dipole. If you were to feed with coax, to an end fed dipole, and that coax is quarter wave long, you would transform t

I use version 11 with little difficulty. Selecting Preferences->Analysis Controls->Manual Controls will bring up the dialog that most resembles that in the N0SS write up. Use Scope 1, 128msec averaging and 2048 FFT points (Pentium 4) and you'll see the same results. On Tue, 09 Aug 2005 15:44:07

Vic, I have noticed the effect in the San Jacinto Mtns east of here. I was at around 8000'. I layed out my end-fed wire as a sloper with the low end pointing east on relatively flat terrain at the campground. I later moved it so that it sloped from the edge of a drop off down to a scrubby tree on a

I operated FOBB 2005 with my K1 in 100F (38C) heat in the shade. At one point, without really realizing it, the K1 was in direct sunlight filtering through the trees. The top of the case was very uncomfortable to touch. Obviously, I didn't do any objective testing to see how that affected drift. I

I just used a portable inverted vee fed with 300 ohm ladder line and the elecraft 4:1 balun during our camping trip up in the hills of northwest NJ. The K2 heard like a hawk.

Hello Ian! I am trying to get back into CW and the filters are really odd. If I bypass the DSP, everything works as I would expect. I can zero beat using the spot button and the filters are fine. If I have the DSP in, I cannot get the CW note down to the spot frequency and if I alter from FL1

I would like to correspond with anyone who has tried portable QRP operation from a high location, using a low horizontal antenna at the edge of a sharp dropoff. In the Moxon antenna book (chapter 10), he says that a simple dipole or inverted vee at a low height in such a location can show exce
