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. 73, Mike K2MK From: Barry N1EU [via Elecraft] Sent: Monday, February 08, 2010 4:44 PM To: Mike K2MK Subject: Re: K3 DSP AGC Question Mike K2MK wrote: 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. 73, Barry N1EU -------------------------------------------------------------------------------- View message @ http://n2.nabble.com/K3-in-a-cw-pileup-needs-work-tp4523884p4537307.html To unsubscribe from Re: K3 DSP AGC Question, click here. -- View this message in context: http://n2.nabble.com/K3-in-a-cw-pileup-needs-work-tp4523884p4538114.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
