Re: [Elecraft] K3S audio board for K3 upgrade?

Great advice. Mine, from one who has done this unsuccessfully, and then with advice, done it successfully, GO SLOW. This means small changes to one parameter and some listening time before another change. The changes to the various AGC parameters will have subtle effects, not all of which

Re: [Elecraft] K3S audio board for K3 upgrade?

Gene (and all), Yes, the AGC settings do help a lot. The K3/K3S has enough gain that often the AGC is activated on the atmospheric noise in the band. However, I think your chosen AGC settings are a bit extreme for general use, but if your ears tell you it is good for you, then keep those

Re: [Elecraft] K3S audio board for K3 upgrade?

This has been an interesting thread to which I have experimented a bit more and found the AGC setting recommendations from a couple of posters to be very valuable, and Eric's suggestions on BW settings to be a nice compliment to play with. Although, my ears still like a little HF, I like the sound

Re: [Elecraft] latest K2 serial #?

Robert, Yes, those two mods are old, and apply only to the A level boards (below SN 3000). There have been improvements in the K2 sidetone incorporated into the B level boards, and are also included with the A to B mod kit. The changes added a 47k resistor in series with C24 (R11 for the B

The dates of the two sites mentioned are pretty old. I imagine that any such mods or similar changes were incorporated in later K2's. Is this the case? ...robert On 03/22/2016 14:06, Bill W4ZV wrote: KC6CNN wrote They K2 might be old school, but you got to love the sound they have with CW.

None. Transmitting into a high SWR (such as no antenna connected) will result in the power amplifier shutting down to protect itself as long as the condition exists. Hook up an antenna or dummy load. You should see full power output. Elecraft has gone to great lengths to protect all of their

two more cents - are we rich, yet? Couple more comments on K3 audio quality and etc. The MOT metal mobile speakers were designed for FM mobile and did sound good. I don't have any so have not tried marrying one to a K3. SSB sounds different than FM, especially full quieted FM. Installed a

Using a couple old Radio Shack "Minimus" speakers, I find the K3s to be the best sounding and easiest to listen to radio I have ever had. I agree, the TS-2000 as well as the TS-480, while an excellent mobile rig, does in fact roll off the higher frequencies too much for my antique ears. This

I agree with Vic - I want minimal AGC action, only kicking in on the strongest signals to keep the audio level below the ear's attenuation reflex (see http://n1eu.com/K3NA_rx_audio.pdf ) I have my threshold set at 14 (along with AF Gain at approx 9 o'clock and RF Gain adjusted so I can just hear
