[Elecraft] Use more heat - soldering technique caution

I would like to caution newcomers and first time builders on the turning the knob on your new adjustable soldering station (e.g. Pace, Haako, Weller, Metcal) to achieve more heat. There are actually THREE factors at work to have the proper amount of heat transferred to a joint for soldering

Re: [Elecraft] N1MM

Hello Bob. I'm also using a wireless connection with a card in my old IBM 380ED and like yours, it works quite well. You didn't say what version of Logger you were using but I'm guessing that as far as parallel port keying goes that it does not (or at least should not) make any difference. You

[Elecraft] External Keying Auto-Detect problem

I finally got my problems with N1MM Logger sorted out, only to find that my keying adapter doesn't produce the expected results. I have a pair of 1N4148 silicon diodes going from the Logger key line to each of the dit and dah lines to the K2. The cathode of each diode goes to the common Logger

Re: [Elecraft] K2: KAF2 Versus 2.2 kHz KSB2

Hello Paul, I'll refer you to a previous post that I made concerning this. My implementation is definitely not a pretty sight though; I quickly tossed the circuit together, and it sort of 'lays' inside the K2 (protected with electrical tape, of course:-)). Someday I'll get around to making a

RE: [Elecraft] External Keying Auto-Detect problem

The K2 is suposed to detect simultaneous closures on the dit and dah lines, and interpret that as a hand key input. Not doing it so far. When I turn on the K2, the firmware versions displayed are 2.03d and 1.07. Bob: Select - Menu, InP - then - PdLn, Now tap DISPLAY. You should briefly

[Elecraft] K2 ALC Anomaly Using PTT

Anyone who uses a K2/100 with a linear needs to know that the K2 ALC does not kick in if PTT is used and the K2 display is in the RF mode. This can cause the input to the linear to be overdriven. This condition can also cause the K2 output not to be linear. It is necessary to put the K2 in

Re: [Elecraft] External Keying Auto-Detect problem

Well, the mystery is solved. I had not realized there was an on/off menu choice for the auto-detect function. Two hams told me about it, and yes, it did the trick. Now in business, and I can get back to trying to learn N1MM Logger. 73, Bob N6WG ___
