[Elecraft] K3 DSP AGC Question

[Mike K2MK]

Hi Barry:

I was annoyed when I first read Lyle's post. It sounded like the right hand didn't know what the left was doing. Really, why optimize the amplifier for 32 ohms and then only offer a 200 ohm headset for sale. But Lyle's further explanation was reasonable and I probably overreacted.

I know my hearing is not what it used to be. I first used the speaker jack during the ARRL 10 meter contest in Dec 08. The band was noisy so I had the NR on but there just wasn't enough volume available to pull out the barely audible stations. (Having a no gain vertical doesn't help either). There really is no good reason to keep the headphones in the speaker jack on the other bands. I just do and I keep the AF level correspondingly low.

I took note of your recent posting about the HD-280s. I put them away when I got the K3 and the Proset. But after the discussion regarding isolation I pulled them out and they have slightly greater volume then the Proset. I like the Proset because it has very comfortable ear pads. The 280 has a tighter grip on my head and the pads are a bit more rubbery. I think that's why I stayed with the Proset. But the ARRL DX contest is coming up so I think I'll give the 280s a whirl and see which I prefer.

  I was very disappointed to read your post. I purchased a Proset headset directly from Elecraft when I bought my K3. According to Heil this headset has an impedance of 200 ohms. Is that why I have to plug my headphones into the rear speaker jack to get sufficient audio output from them? Why would you folks sell a headset that does not complement the K3? I am really disappointed. 
I routinely use a 200-ohm Pro Set for ssb plugged into the headphone jack and it works like a charm.
