CW-to-DATA

[Ron NA9F]

Two questions:

1st.  While using the internal CW-to Data mode I notice a 4 sec idle transmit period before exiting to receive mode. Is there other way besides, sending "..--" at the end of your tx, to switch to receive?  I think 4 seconds of idle state is way too much and do not really like to have to send ..-- after each transmission.  

2nd.  What has anyone found out about tuning in a PSK signal that may not be covered in the manual?
It seems like some stations can be easily tuned fin while others are much harder.  I have noticed that Digipan copies better then the K3's decode but it may be my inability to get the tune right.

At this time, your two available options are to send this sequence, or
wait for the idle time out.

Be sure you have the selectivity tightened up around the signal of
interest before you do the SPOT to auto-tune it.  Might take two or
three presses.  Go to FINE TUNE (1 Hz steps) if necessary.

To clarify, once I have the PSK signal identified, I narrow the
selectivity to 50Hz and, if necessary, manually use 1 Hz fine tuning
after AutoSPOT.  I find AutoSPOT usually does just fine, though it might
take 2 or 3 presses of the button to get it just right.  WIDTH and QRM
dictate what needs ot be done, and experience using it will tell you
what steps to take.

The K3 PSK decoder is not a wideband, waterfall-style decoder. It will
only work properly if there is one and only one signal in the passband.

Hi, Ron.

If you're sending with a paddle, you need to send "..--"

If you're sending with software (the KY command), you can send KY followed
by an ASCII EOT character (0x04) followed by a semicolon to stop sending.

The K3 Utility terminal page uses this technique.  If you're sending from
one of the K3's CW memories, make the last character in that memory the ..--
character, and when the memory is "played", carrier should drop.

The Elecraft PR6 has sold.

Also have an INRAD

1.8 filter that I would like to trade for a 2.1 INRAD or sell outright.

250 hz filter that I would like to trade for a 400 hz INRAD or just sell
outright.  

Please reply off the list.
