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.
