>>> HF <<< 

ham radio shortwave PACTOR AMTOR GTOR RTTY MT63  program 
with self-decoding CW elbug function
and F6FBB mailbox interface

Hallo friends, 

HF is a linux ham radio fsk digimode program,
which can do also the realtime ARQ modes without a ptc, 
only with a soundcard and a pc and linux. 

The heart of the program has originally been made by Tom Sailer, many thanks Tom! 
Long time it has been sleeping (I had no time to admin it since 2007),
now (9/2018) it has got a new polish and lot of fixes by
Jaroslav Skarvada <jskarvad@redhat.com>, thanks!
I just (7/2019) uploaded Version 0.9 which is based on his work.
You also find latest version and Jaroslav fixes here:

There are some great things in hf:

• hf's terminal hfterm can connect via TCP/IP with the BBS mailbox program F6FBB (well-known from packet radio),
  so you can use hf as an automatic pactor / amtor mailbox.

• automatic receive / transmit and beacon functions

• 3 calibration tools, which also can be useful for many other purposes:
  dcf77rx, also with the 'no-mmap'-option, can also to set the system time after the German DCF77 radio clock beacon.
  a circuit to build a little longwave -> 4 MHz converter is included.
  reffreq uses any reference tone 20 -22000 Hz.
  ratecal1 (by Pawel Jalocha) uses pulsed signals, calculates your real soundcard samplerate directly.

• The elbug decodes your keying. Good for training. Also with mousekeys.
  Also as simple console program 'elbug' in the package (for paddle only). (A better version of this in github.)

There are some difficult things in hf:

• hfkernel, the coding/encoding part of the hf package, is programmed in a very close-to-hardware way,
  which means, it will not run with all hardware, just try! I just tried and it was good on my Debian 9, old pentium.

• It may also not like some newer libraries... you must get old GTK 1.2.10 GUI (graphical user interface),
  how to get it is in the hf-howto.txt.

• You must know, the modes AMTOR, GTOR and PACTOR-1 are somewhat historic.
  
  Enjoy it!

How to install

Read the HF-HOWTO.txt! It might help...
In case "MMAP" error with fsk modes: enter '-n' into the config menu at general/kerneloptions.

Documentation

F1 opens HF-HOWTO.txt (English, very long, recently updated 2019, latest news about how to install) 
or  DE-HF-HOWTO.txt (German, not updated yet for install things since 2007).
short help in man hf, man hfkernel, man dxf77rx, man dcf77gen  and more.
