Re: [digitalradio] flarq compatible modes

Dave,

Is the beacon interval OK?

Wouldn't it better be 30 MINUTES?

I wonder, because I used to run beacons every 10 minutes on packet.
Less than that could be considered "antisocial" by some people... :-(

73,

[digitalradio] flarq compatible modes

2009-08-13 Thread David Freese
I have received several reports that users have not been able to get

flarq<->fldigi<=>fldigi<->flarq

to establish an flarq connection.

I think that the problem might have been a failure on my part to delineate 
which modes are compatible with flarg.  I have updated the on-line 
documentation for flarq thusly:

Flarq can be used with the following digital modem as the transport layer:

BPSK all baud rates
QPSK all baud rates
MFSK all baud rates
DOMINOEX 11 or faster (do not use FEC)
THOR all baud rates, 11 or faster recommended
MT63 - all baud rates, flarq timing should be increased to accommodate 
mt63 latency

for example: MT63-500 requires flarq be set up with:

Wait time 30 seconds
Timeout 300 seconds
Tx delay 500 msec
Beacon interval 30 seconds

on both ends.  Watch the flowers grow :-) 

Probably the most important thing for persons trying the flarq / fldigi suite 
to know is that they should not use DominoEX-FEC or Olivia as the transport 
layer.  These modes suppress the transmission of the required control codes for 
the flarq data stream.

Not with DM780 - now I could do this, sooner or later DM780 & fldigi will 
support the CALL-ID feature, when we do this a log could make sense.

Yes, using Commander, I set the dwell time for scanning to just 3 seconds.  I 
am scanning four 3Khz segments over 12 seconds.  I may miss a few RS IDs but it 
should be interesting.




[digitalradio] More on RS ID ... the pleasure of

2009-08-13 Thread Andrew O'Brien
 I know several have written about RS ID now that it is fully
implemented in Multipsk, DM780, Pocketdigi, and Fldigi.  I have been
off the air for a few weeks , today I installed software on my new PC
(DX Lab Suite, Multipsk,  HRD/DM780 and FLdigi always go on a new PC
first! )  I booted up DM780 to take a look since I am a little behind
in the latest developments for DM780, I heard NO signals on the band
but within the first minute I saw  " RSID:THOR 16 f=2Ø4ØHz "  I
clicked to allow the RS ID and saw

"CQ CQ de VE9NC VE9NC
CQ CQ de VE9NC VE9NC"

I am going to work now, but have decided to leave DM780 active and my
rig on 20M just to see what modes DM780 detects while I am out.  The 3
Khz spread my rig limits me to gets to be a little sad when compared
to a SDR bandwidth, maybe I'll play around with Commander and see if I
can scan different 3 kHz sections a few minutes at a time.

[digitalradio] MT63 specifications

2009-08-13 Thread David Freese
An excerpt from Pawel Jalocha's source code distribution:
The MT63 modem is intended for amateur radio as a conversation (RTTY like) mode 
where one station transmits and one or more other stations can listen. In 
short, the modem transmits 64 tones in its 1 kHz bandwidth: the audio range for 
the tones is 500-1500 Hz. The differential bipolar phase modulation is used to 
encode 10 bits of information per second on each tone. The user data in the 
form of 7-bit ASCII characters is encoded as a set of 64-point Walsh functions. 
The bits are interleaved over 32 symbols (3.2 seconds) to provide resistance 
against both pulse and
frequency selective noise or fading. The character rate equals to the symbols 
rate thus the modem can transmit 10 7-bit characters per second.

This modem can as well run in two other modes obtained by simple time scaling, 
the possible modes are summarized here:

BandwidthAudio RangeSymbol Rate
Character Rate
Interleave / Char.
500 Hz
500 - 1000 Hz
5 baud
5 char / sec
6.4 or 12.8 sec
1000 Hz
500 - 1500 Hz
10 baud
10 char / sec
3.2 or 6.4 sec
2000 Hz
500 - 2500 Hz
20 baud
20 char / sec
1.6 or 3.2 sec

For each mode the interleave factor can be doubled thus each character becomes 
spread over twice as long period of time.

The MT63 modem is made for single side band operation. The audio generated by 
the modem (sound card output) is applied to the SSB modulator. On the receiver 
side, the output of the SSB demodulator is put into the sound card input. The 
envelope of the MT63 signal is not constant as in other multi-tone systems - it 
is rather noise-like.  One must be carefull not to overdrive the transmitter.

The receiver of the MT63 is self-tuning and self-synchronizing thus the radio 
operator is only required to tune into the signal with +/- 100 Hz accuracy for 
the basic 1000 Hz mode. The modem will tell the actuall frequency offset after 
it is synchronized. The operator should not try to correct this offset unless 
he is able to tune very slowly his radio receiver, because the MT63 as a low 
rate phase modulated system does not like sudden frequency changes.

The MT63 is a synchronous system and it relies on the sampling rate to be the 
same at the receiver and the transmitter. At least the sampling rates should 
not be different by more that 10^-4. MT63 samples at 8000 Hz thus if your card 
runs at 8000.5 it's probably OK but if it runs at 8005 Hz it's not good !  An 
extreme example can be my Soundman-16 (PAS-16 clone) which when asked to run 
8000 Hz tell me, that it can only do 8008 Hz and it reality it runs at 7910.3 
Hz which makes an error of more than 1% - far too much for the MT63 even at 
infinitely good S/N.
My other two cards (DSP-16 and Ensoniq 1371) are more reasonable: they show an 
error of 0.3 to 0.5 Hz at 8000 Hz sampling.
