[Elecraft] K3 S-meter Reading with ATT on and PRE off

I wanted to ask about the K3 S-meter readings I noticed: 1. S7 with ATT off and PRE on2. S5 with ATT off and PRE off3. S3 with ATT on and PRE off These were for a CW signal on 20M; I read that turning the attenuator on and preamp off provides a better signal by lowering the noise level in the

[Elecraft] Unable to get mic working on K3

I recently built a K3 and have been using it in CW mode so far. When I tried testing it in voice mode, I was unable to get the ALC to show any movement at any mic gain level (as though the mic was not working). I am unable to test voice monitoring as well. I am using the front panel mic

[Elecraft] K3/100 into DX-CC antenna (HI-SWR)

Hi all, Just spent the day putting up a multi-band DX-CC (fan dipole, 80-10M) in an inverted V configuration. Unfortunately, I could not get the center mast extended beyond 20 feet, with one end up ~9 feet from ground, the other, ~5 feet from ground. I am seeing HI-SWR on all bands. Any

Re: [Elecraft] K3/100 into DX-CC antenna (HI-SWR)

Sorry for the multiple emails; on more careful checking, I found that the SWR is nice and low on 40, 15 and 10. High (3+) on 20 and 80, so I must have some mismatch on just 20 and 80. Jay From: j_kris...@msn.com To: elecraft@mailman.qth.net Subject: K3/100 into DX-CC antenna (HI-SWR)

[Elecraft] Fans on K3/100

Do the fans on the K3/100 come on automatically, depending on the PA module temp, and remain off at other times? Thanks, Jay (KD6AMA) __ Elecraft mailing list Home:

[Elecraft] K3 SWR

Just completed assembling my new K3/100; I am completely new to this rig, and just getting used to it. In initial transmitter power calibration into a dummy load, I saw an SWR of ~1:1. However, into my 20M mono-band dipole, I see it is ~1.8:1. I am wondering if anybody can help answer these

[Elecraft] ESD Protection for K3 Assembly

Hi all, I received my K3 kit yesterday and am setting up to start assembly. I bought an ESD mat and a wrist band. I was wondering what I should connect the alligator clip from the wrist band to, for best protection? Thanks, Jay (KD6AMA)

[Elecraft] Help with K3 Evaluation in Palo Alto

Hi, I have been considering for some time about buying a K3; however, given the limited space and antenna constraints (have a simple 20M dipole about 30 feet up) at our home in Palo Alto, I am not sure if I can put together a decent set up worthy of week signal CW DXing or contesting. I am
