Hisashi,
I'd like to know if you experience the dropped characters on receive, or
during
transmit? You show it as a RTTY decode question, but is that specific?
Read my previous post carefully. I am also describing a similar thing
during transmit. Paul has been
working on it. I'd like to see this get fixed.
I'm sure if everyone using a keyboard will report their experience, we can
establish if it is a hardware problem for a few,
or something common to all. I bought the SVGA option when I learned of it
accepting a keyboard. It hasn't been dependable for use.

Subject: RE: [Elecraft] P3 SVGA RTTY decode question
Sorry, I guess my frustration is with the limited documentation on the
P3 SVGA. Twice I thought it was defective but it wasn't.
So far I've found that the SVGA bias needs to be turned way down from
the default of 9.9 to 1.2-1.5, and that I'm losing simple serial data
from the K3 to the P3 SVGA on receive. I think this is a serial line
problem and Gary from Elecraft suggests turning down the rate from
38400.
Also, the USB keyboard I have (a Cooler Master I just got) doesn't
appear to work and I'm sure it's another problem on my side. Everything
else has been.

Paul, and others,
I think Hisashi is describing using RTTY what I have been talking about
using CW with a keyboard when I said that some
characters (not elements of the characters) are being lost during
transmission. They show on the monitor, but not on the P3 and
are not being sent.
At this point, I'm wondering if Hisashi is seeing this while transmitting?
or does he see it during receive? If during receive,
that would be a new problem.
