I recently purchased a Bose QC-45. I used it for about 5 minutes in a
CWops contest, and got RF in the left headphone. I disconnected it, and
returned to my Bose QC-35's. The QC-45's have been returned to Amazon.
I had a similar problem earlier in the year with the Bose 700
headphones. I tried
I have two K3 questions:
1. In Data MD, AFSk A, you can set the baud rate to either 45 or 75.
Is the baud rate just for the RTTY reader? Does it affect anything else?
2. With my K3s power set to 100w, RTTY starts at a little below 50w
and and then fairly slowly builds to 100w (measured on
Last December, I posted a message concerning whether Elecraft is still
supporting the K3. My K3s developed a problem with its 100w amplifier.
Wayne quickly responded and confirmed Elecraft still supports the K3
100%. A few days later, Doug from Customer Support contacted me.
Doug told me they

impatient. I'm happy!

FWIW, I bought a pair of the Bose 700 headphones, and I'm NOT happy.
They are very susceptible to RF, especially on 40 and 80m. They make

I have a slightly different idea about how I would like it setup: I
would like the K3 to be configured for either the Internal or External

I ordered a second K3 at Dayton. It arrived Friday (I requested delayed
delivery). Its a fairly "vanilla" K3/100: KXV3, 400 Hz filter. I built

Several things worth noting:
1. The Assembly Manual (Rev L7) has been fined tuned.
I'm curious how others are configuring your AGC settings with F/W 4.51.
