On the Teletype model 33 and 35, one character delay was enough
for the carriage to return to the left margin. That made the CR
LF sequence the favored new line. (The LF could be executed in
one character time.) These machines used ASCII code as compared

Well as I understood it from years ago it was not just setup but condition of

the carriage actually be returned and ready in time? Quite often not so the
solution was to send multiple CR's or LF's. The mechanical eq

Hello,
For those of you who put together a Genovation external keypad I have
updated the Macro spread sheet located at:

In pre-history (when the Model 19 was state of the art) we simply hit LTRS
several times after sending figures to be sure it was received. Also, every
line of text ended with a Carriage Return - Line Feed - Letters key sequence to
be sure it was ready for more text.

Ever since I bought my KX3, I have wondered just how the software handles the
shift between letters and numbers, but I never thought to ask this forum. I
thought about doing a few tests to find out, but since I haven't worked RTTY
since I sold my Model 19 in 1990, it just never was a priority
John,
Don't forget to check the connections on the outside of the K3 as well.
A loose PL-259 connector could cause that same behavior.
PL-259s need to be tightened finger tight, and then given just a little
bit more tightening with pliers to assure a good connection to the coax
braid.

I would be interested in all of the utilities running on Raspberry Pi 3 as

The KPA500 is linear, with 13 db gain. That means the KPA should output about
20 x the input power.
So, for 5 watts in, you should get about 100 out, for 10 in about 200 out.
There are slight variances due to the KPA's input network.
Also, be sure to check what the transceiver is putting out co

There has been much discussion of desoldering techniques. Many express their
praise of various desoldering/soldering machines. However machines have many
negatives starting with the need for a high degree of skill and expense. In
short they are not practical for the once a year project builder.

cross-platform command-line firmware updater for all Elecraft devices,
specifically one that includes Raspbian. I did not get a response from
anyone at Elecraft. Obviously, my suggestion is not quite the same thing as
