Re: Generating CW-morse signals with a straight key

[Barry Duggan]

To Harald, Cinaed, and others interested in Morse code generation:

I have created a text to Morse code generator. See 
https://github.com/duggabe/gr-morse-code-gen

Yes, the MorseGen.grc is for 3.8, but if you replicate the flowgraph 
with 3.7 and use epy_block_0_0.py in an Embedded Python block, you 
should be able to have a functioning system.

Let me know if you have any questions.

Happy New Year! and 73,

Hello All,

Hoping that amateur radio is not to far away from common use of
Gnuradio mailing list, but amateur radio is making me looking to GR
since 2001.
There is a plan to use a Gnuradio based transceiver for µ-wave
contesting, as it has been shown by W7FU or KB1VC (SoDaRadio) or DL9SW.
A needed condition is, to key HF with morse code using a straigth or
simple morse key.

Doing this with just looking to the status of /dev/ttyUSB0-CTS pin is
not sufficient, basically some of the keyed code is somehow swalloed.
Neither with python code or with a C++ OOT module i got it solved.

How to get this solved? (Hardware keying or modulated cw is not a real
option).
