P3 SVGA RTTY decode question

I was copying RTTY on my P3 SVGA and I found that it was dropping a lot
of characters. I finally figured out how to decode directly on the K3
and it wasn't dropping characters at all.

Is there something I have set up incorrectly?

Thanks.

Re: P3 SVGA RTTY decode question

Hi Hisashi,

The P3/SVGA board is acting as a terminal. It does not do any decoding. It just displays the decoding done by the K3. If you're missing characters you may want to adjust the threshold on the K3. See the decode tips in the K3 manual on page 33.

Hello Hisashi,

The P3/SVGA terminal mode which allows you to display decoded CW/RTTY/PSK31 text on an external monitor uses the decoder built in to the K3. If you are missing characters on the SVGA display, first make sure that the K3 is correctly configured to decode the correct mode. Another common problem is when the K3 utility is connected along with the P3/SVGA. You cannot have both operating at the same time.

73,

Once again, I wonder if I'm being clear. THE TEXT ON THE P3 SVGA IS NOT
THE SAME AS ON THE K3. I'm not sure what the issue is.

Re: 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,

I think Hisashi is describing while using RTTY what I have been talking
about while 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 K3 and are not being sent. (I'm saying this
for Hisashi's benefit so that we are in sync.)

Hisashi, at this point, I'm wondering if you are seeing this while
transmitting as I do? or do you see it during receive? If during receive,
that would be a new problem.

Re: P3 SVGA RTTY decode question

My problem is during receive. I wonder if there's more problems on the
serial line than I thought. When I have some time I'm going to put a
'scope on the serial lines to see if there's anything odd to see.

Re: P3 SVGA RTTY decode question

In reply to this post by Hisashi T Fujinaka

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.

Hisashi,

Sorry about these posts getting out of order. Something in my email client
changed the 'from' address and my post was rejected. Will fix that.

Okay, your problem is during receive. That is different from what I have
been reporting, but perhaps I should look for it during receive,
which I will. Thank you. For those who are wondering, the K3 display
decode will be different from what appears on the monitor.

As for scoping the serial lines, It would be good if you find something. It
seems like a sync problem.

Re: P3 SVGA RTTY decode question

Dick and Hashshi,

I would suggest removing the serial cable going to the PC as a test.
That will assure nothing other than the K3 to P3SVGA is flowing over the
two serial connections.
