Thinking about these numbers reminds me of
another question I've had. The fact that IMD was
measured at 94-95 dB at 2 kHz, and there was no
mention of noise limited, makes me wonder what
the phase noise performance is. I also recall either
Wayne or Eric reporting BDR at 2 kHz of 143

While the numbers which Eric posted a few days ago are interesting, not to
mention very good... Congrats! ...I am still wondering about the 2100Hz and

interesting, because they would

I found that when using the tune button, the power that is measured and

For example, when adjusting the power control for 4 watts, the displayed

Seems that I have read before that someone was having trouble with the phone

Ed,
A couple of other thoughts on this, assuming that no relays are
switching as you vary power from 80-120 W (see previous e-mail).
We need to get an o'scope on your TX output at the time the SWR goes up
to see if the PA is unstable. If it isn't, then perhaps the SWR bridge

my paddles, but not for CW!)

If Elecraft wishes to have the BEST opportunity for the ARRL to laud

When you turn on the decoder there are presently a few options available.

UNfortunately, you're not going to find many devices (other than the
