[Elecraft] Elecraft SSB net results (5-30-10)

Conditions on 20 meters at net time were so bad that only ten stations succeeded in checking in. Only a few stations at about 1000 miles from me were strong. Most were a struggle to copy. No discussions took place during the 12 minute net. Here is the list of the group: Station Name

[Elecraft] K2 VFO problems

Hello all, I have finally gotten my K2 up and running on all bands. What started happening during the final assembly I&E speaker installation and top install, is that I cannot change frequencies after a short warmup, and sometimes from a cold startup. Sometimes spinning the VFO knob made it work

Re: [Elecraft] [K3] K3NA on 5 pole vs 8 pole filters

Gents -- I am not sure where the misinformation began that I use 5-pole filters. None of the K3s used by Radio Expeditions, and none of my personal K3 radios, use 5-pole filters (other than the stock filter). My personal filter configuration at the time I bought my radios was: 2.7 kHz st

[Elecraft] K3 dsp rev D hiss audio

Hello, I have now K3DSPUPGD (Rev D). A lot of good, but... there is one drawback. I noticed more hiss on audio (Heil headphones) even AF gain off! I had Rev B and that was very quiet. That hiss is very notable on CW with narrow filter. It is fatique to listen white noise. What experience you hav

Re: [Elecraft] Buryflex all the way to K3?

Good choice. My first (and probably last) experience with BuryFlex is that it should have been named SortaFlex. It's pretty stiff compared to Belden 9913F7, which is a dream to work with in comparison. (IMHO, of course. I know some people don't like it.) At HF and 6m, though, ten feet of 8X will

Re: [Elecraft] Buryflex all the way to K3?

Thanks all for the input. I'll just run 8X jumpers from my bonding panel to the K3. The operating point is on the first floor directly above the basement service entrance and bonding panel with polyphasers so it will only be 10ft. Now to order a bunch of coax and connectors. 73 jim ab3cv ___

Re: [Elecraft] RFI PC Speaker Hum

One thing that I believe has not been mentioned in this thread is a very simple solution to the hum problem. Since the K3 already has an audio power amplifier, amplified speakers are not really needed. I had an old pair of computer speakers - which hummed every time I transmitted on the K3. Then I

Re: [Elecraft] [K3] K3 fan noise, part XXLIV

I have to agree with the idea that this is about ears. At one time in my youth I could hear the 15k whine from a TV horizontal flyback transformer if a TV was on in the room. The sound was part of the TV and I had to listen to it to watch TV. It was clear, and loud. I could clearly hear harmonic

Hi Joe, I'm going to try your suggestion. The way I understand your post is that you installed the bypass caps directly on the amplifier board, one cap for each speaker wire, each grounded to the circuit board's ground? My speaker's circuit board is difficult to work on, could I accomplish the

Re: [Elecraft] K2/100 Distortion on 80M

Barry, There is nothing unique to 80 meters in the K2 that should create distortion on only that band, so I would not suspect the bandpass filter. One thing you might try first is to tuck the KPA100 ribbon cable and speaker wire up into the upper corner of the control board, and as far away fro

Re: [Elecraft] K3 ATU

This functionality has been in the radio since firmware release 3.03 on March 17th of 2009. Essentially the radio keeps memories of the ATU settings. The spacing of these "memories" are different depending on what band you're in... 160 - every 10kc 80 through 12 - every 20kc 10 - 50kc 6 - 200k
