[Elecraft] P3SVGA data RTTY FSK D

[Adrian]

Hi Toby, I'm not much into psk31 etc these days. I tried it out yrs ago and
got bored fast.

For RTTY the CWT twin tune bar should carry even bar weight each side to
coincide with best copy.

 

However the P3 green line and shade area does not match up well with the
twin dropper signal when this happens.

It's sort of get the green line to the right of the right dropper to get
into the ballpark.

 

It would be nice to get a P3 visual marker in RTTY that could be lined up
better.

I found a copy of 4.48 & installed, I have most of the old firmware versions
on my pc saved.

 

4.50 came out next with the agc deal and bad decode and so on.

Hi Adrian,   I wnet back to 4.47 Firmware in the K3 and find decoding on the
P3 is improved. 

 

CW operation with the P3 is perfect and no issue. 

On PSK I have made contacts but it seems my TX freq is slightly off from my
RX freq.  I have tried the Reference Freq. calibration and can make changes
to center the received signal.  I have the SPAN set to 5KHZ for PSK and find
that allows me to see all the signals better.  I wonder if you have had any
experience with PSK?

 

I have not tried RTTY yet.
