Re: [Elecraft] K2/100 Problem with Hi Reflected Power driving amp

2009-01-10 Thread Stephen W. Kercel
John: As another poster noted, why do you use a tuner between the K2 and the amp unless the amp has an untuned input? Are you sure that the tuner is actually adjusted to present a 50 ohm load to the K2? Echoing some of Don's points: Is there something wrong with the timing of the keying

Matt: At an unconscious level of cognitive processing if you were listening to two replicas of the same signal, with one slightly delayed, if the delay were on the order of 1/100 second and if your ear were very highly trained, you might be able to tell that something is different about the

, if such delays are enough to blur 25 WPM CW, they would be enough to be easily noticed in static crashes. Of course, that still requires some sort of polarity disparity to create the effect observed by Mr. Zilmer. 73, Dave AB7E Stephen W. Kercel wrote: Recall that radio waves move

[Elecraft] Amplifier Input Impedance

2009-01-26 Thread Stephen W. Kercel
Fellow Elecrafters: Is it possible to measure the input impedance of a linear amplifier by using an antenna analyzer (such as the Pal Star) at the input of the amplifier in place of the rig? Would the amplifier input impedance be the same for the very small signal that the analyzer generates

Thanks to all who have replied. The amplifier that I have in mind is an old Dentron GLA-1000B that I am restoring. It is a grounded grid sweep tube amplifier and uses fixed pi networks (a different network for each band, selected by the band switch) at the input. It is supposed to have a

Elecrafters: About a year ago, I finally hooked up my K2 to a computer. Following the advice of several list members, I got a WinKey keyer instead of trying to run CW keying through the serial port. The WinKey is inexpensive, easy to set up with the N1MM contest program, and provides flawless

DW and all: A slightly different hunting analogy might be more illuminating. Here in Maine, bear hunting is very popular. There are two ways to go about it. If you're a local, you learn the bears habits and habitats, and you go out and stalk the bear, and if you are very much smarter than the

John and other Elecrafters: I am an extremely happy K2 owner. I have operated a K3 and I intend to get one someday, but I am not in a particular hurry. In the interest of full disclosure, I am strictly a CW guy, and any voice quality advantages that K3 might have over the K2 are lost on me.

[Elecraft] Tuning Pulser with K2

2009-03-15 Thread Stephen W. Kercel
Elecrafters: I built a tuning pulser to use with my K2/100 to tune an external linear amplifier. The pulser is the AG6K design. The pulse is 12 ms on and 24 ms off, and repeats about 28 times per second. This is (by design) much faster than the normal 25 wpm or so keying out of the keyer. The
