Re: [Elecraft] K2 - signal loss in band-pass filter

Thanks for the input Dave. It sounds like a good solution. But I'm curious: Why does lifting the ground leg of the regulator and 'inserting' a diode in series compromise the regulator's short circuit protection? Does it require a direct connection to ground? David Lankshear wrote: Of

Re: [SPAM] [Elecraft] K2 - signal loss in band-pass filter

Dave, If you jack up the the type of 8V regulator used in the K2 by adding a diode in series with the regulators ground lead, have you found any sign of oscillation at the regulator's 8V output terminal? Also, if my memory is working properly, the regulator's ground lead is connected to its

[Elecraft] Elecraft SSB Net -- declare dormant for summer?

Activity on the 40 and 20m SSB nets has decreased with the coming of spring. Noise levels are high, propagation is poor. Outdoor and family activities take priority. I'd rather declare it dormant than waste time calling nobody. I suggest we keep the schedule listed on the Wiki site:

[Elecraft] K3 Kit

Forrest, Your elecraft forum post on your K3 #977 is very good. I had the same problem with the 2-56 screws on the front panel. I found some extra steel 2-56 screws and used them to clear out the front panel holes before using the Elecraft supplied ones. It seems to be some paint that got into

[Elecraft] PA Temp

How hot does your K3/100 PA run? And how hot is safe? I was sitting in a pileup at 90 watts and watching the PA Temp - it got up to around 41 or 42 C (about 100 F) so I turned the fan up a notch or two and it cooled right back down to around 20 C (70 F). 73HankK8DD -- 'Never argue

Re: [Elecraft] PA Temp

Hank, I don't know how hot is safe for the K3 PA devices, but I would believe your 42 deg C is OK. I am going to go out on a limb and make some assumptions - that the PA transistors are operating at 65% efficiency, that they are rated for the normal commercial operating temperature of 125

Re: [Elecraft] the high speaker does not function any more

Denis, I can only think of two likely reasons that your headphones work but your speaker doesn't.: 1) Remove the top panel on your K2 and look for a connector on the front right side of the radio (close to the on/off switch). It is labeled SPKR and P5. Make sure the connector is connected and

Re: [Elecraft] PA Temp

We will let the heatsink get up to 85C before dropping the KPA3 off-line, that still has plenty of safety margin for the transistors. 40-42C is actually on the cool side for heavy usage. But it never hurts to keep it cool if you don't mind the added fan noise. Fortunately the K3's dual fans

[Elecraft] K3 receiver sensitivity and preamp

Hi all, One of the first things I noticed with the K3 was that the preamplifier seemed quite noisy compared to my old IC-718. With the IC-718 connected to a dummy load, the noise level rose an estimated 3dB or so but with the K3 I estimated at least twice that. Recent measurements using the
