[Elecraft] K2 #4962 status

I just finished everything and I'm ready for Alignment and Test, Part III on page 74. I switched the power on and it's behaving nicely taking 220mA at 12.2V with the display on and the bar graph in dot mode. That's all for tonight. Ian -- ___

AW: [Elecraft] Low power on 20m using the KPA100 option

Dear all, I have got the answer from Elecraft that C80 and C81 in the KPA100 driver section should be increased to 5600 pF. I had already soldered 2 additional 4700 pF caps parallel to C80 C81, which cured the problem for me. I will reduce the capacity of C80 and C81 down to 5600 pF later.

[Elecraft] Safe continuous power level of KPA 100/ transformer design

Dear gentlemen, I have two questions regarding the KPA 100 option: 1) What is the safe continuouse power level, which can the KPA 100 deliver for example for one hour? 2) How does the PA transformer work? Somehow the cores itself seem to be the primary input of the transformer? Regards

[Elecraft] Problems with KXAT1

Hi! I`ve finished my KX-1 serial 1142 with its 30m module automatic antenna tuner but I have some problems with the last one: 1. When I activate the TUNE function with my Vee dipole which has an SWR of 1.3 I hear the relays working, I see ATU on the screen until it finishes and see P0.1 (so

[Elecraft] tuning of rig after 30 meter mod

Hi, I have noticed that my noise floor is very low on 20 meters compared to 30 and 40. Signal levels are high on 20 meters when the band is open. When I take the cover off, I notice the antenna tuner blocks the 20A tuning, everything else I can get to. What do you suggest? Also, what

RE: [Elecraft] Safe continuous power level of KPA 100/ transformerdesign

Martin, The safe operating level will be determined primarily by heat. For continuous operation, you may want to consider an auxiliary fan pulling air up and away from the heat sink fins - a muffin fan will do nicely and can be salvaged from an old computer. By my recollection devices rated for

Re: [Elecraft] KX1 Question

Hi, Paul. I find the opposite to be true! When I connect my 26ft wire to the BNC centre connector the receiver comes alive with signals! When I connect the 16ft counterpoise to the outer of the BNC, the receive level doesn't change at all. But it does match better :) I also get much better

[Elecraft] K2 external speaker?

I'd like to have my ham SWL radios use the same decent quality external speaker by routing audio probably via one of the lower end Behringer UBxx02 mixers. Does anyone have a favorite external speaker he'd recommend? Soundsweet.com, MFJ, makes little difference as long as its big :-), others?

Re: [Elecraft] tuning of KX1 after 30 meter mod

As I recall, the procedure for tuning the caps is to be done with the tuner out and bypassed with a jumper, so I don't see why the tuner blocking the cap would be a problem. Regarding the alignment tool. I wish I could say for sure which one is needed, but I know the one I use comes from the

Re: [Elecraft] K2 external speaker?

I also have a soundsweet and it is indeed a nice speaker -- very large (about 1 foot per side) and a bit pricey ($130.00 rings a bell, but they charged me sales tax as a NY resident) , but all in all very nice. Tom WB2QDG K2 1103 -- Original message -- From:

[Elecraft] 160 module fustration

Hi folks Im starting to wonder if the 160 module is bad. The antenna switch only works if it is in preamp mode If the preamp is switched on with the r ant on the r ant will not switch off or on. Also large attenuation of signals when it is on the standard antenna. When switched to the r ant

[Elecraft] XV144 Overload test fails

Hi list! I thought I could do the last steps of my XV144. Heard my first 2m beacon today! And I have 20W output power. Everything is fine except: The overload test fails. It fails in a way that absolutely nothing is happening while performing the test. When removing the jumper J8 the XV144 sign

RE: [Elecraft] K2 external speaker?

Mike, Yes, a mixer will do a fine job of that task, and you may even want to route the computer soundcard through it as well. For speakers, I have previously built a small external amplified speaker that I have tailored the range for best communications for my ears, but I am moving to a setup

RE: [Elecraft] 160 module fustration

George, There is not an obvious connection between the Rant and the PreAmp - unless you have something shorted to an adjacent circuit. Check the soldering on the header below the RF Board and on the 160 meter board. The only thing on the 160 meter board are the relays and the low pass filter

[Elecraft] Solar Controllers

Hi I have been supplying a Solar Charge Controller Kit for several years. This controller will keep a SLA or LA 12 volt battery charged from solar panels of 3 to 200 watts. Batteries of 2 amp hour to 110 amp hour have been used with these controllers. I have four of these kits left at the

Yes the Jumper has been removed I took the board out and checked the relay out using the relay schematic and found the relay was not unlatching from the rant position Another one bites the dust! George NE2I Daems Johan wrote: Hello George, Did you remove RF board jumper W1? 73, Johan -
