[Elecraft] RE: Why is K2 so easy to send cw with?

I noticed that on my KX1 too. I just finished my K2 and also notice it there. The KX1 has a really nice dit dah weighting to it. There is something about the weighting that gives sending cw with the 2 rigs a "swing" that is very comfortable. I have yet to figure out the weighting.. I have tried

Re: [Elecraft] Overheated MV209?

If they are still in the circuit, the readings you are getting may be from other components. I would not worry about them at this point, and just continue building, they probably are ok. 73/72 - Mike WA8BXN ___ Elecraft mailing list Post to: Elecraft

[Elecraft] Overheated MV209?

Ok, I think I probably was being a little to particular about making sure the varactor diodes were completely flat on the board as I kept reheating the leads until it would go flat (but they wouldn't as I forgot there was a little nub of wire in the middle that would prevent it). I think I b

RE: [Elecraft] Power Cable Challenged People

Lee, If the power cable and its connectors all display adequately low resistance for the current that flows through them, what does the appearance matter - one person's opinion of 'art' may look like 'crap' to another. In the K2/100 - KAT100 area, there are several alternatives. One is to string

RE: [Elecraft] Your solder may be no clean

Perhaps I can offer a partial answer, Dave. The best "no clean" solder (meaning it does not need to be cleaned for a good, secure and stable joint for many, many years) is the same rosin flux solder we've used for many years. Rosin is NOT corrosive except when heated. At normal temperatures (bel

I spent the evening working on a new power cable for my K2/100-KAT100 combo. It looks like crap, but it seems to work. This does not look professional at all and I an wonder what other people do to make this look like a 2-year old didn't put it together. The upshot of all this (don't you lik

Re: [Elecraft] Your solder may be no clean

Stuart, please help me get educated; why would one not want to get the "No Clean" type? It sounds as though it would not be corrosive, since you don't have to clean it... And if one wanted to go leadless these days what would be the best choice? And differences between rosin and resin core

Hello Don, Yes I understand the purpose of the RC compensation circuit in the drive path to each transistor to offset their decreasing gain as the working frequency increases, and which cannot be fully dealt with by the RCL network in the primary circuit of T1. As you say say they are not intentio

RE: [Elecraft] KPA100 power on 20m/30m, update

Geoff, These are not intentional traps, but are a parallel RC circuit to adjust the base drive with frequency (at low frequencies, the resistors are the main path, at higher frequencies, the capacitors pass more RF). This is done to compensate for the gain vs. frequency characteristics of the tra

Re: [Elecraft] KPA100 power on 20m/30m, update

The "Trap theory" makes a lot of sense, and Don's comment about low tolerance C80 and C81 capacitors would seem to support it. But if the resistors in parallel with C80 and C81 are the only "Inductors" that form the L part of the traps, I would have thought that by simply changing R19 and R20 to so
