Re: [digitalradio] Unknown Digital signal????

[Dave Wright]

There are some known European users in that range, but without a recording, it 
would difficult to say for certain what it is and where is it coming from.

However, keep in mind that while this frequency range is assigned to amateur 
radio exclusively in Region 2, that is not the case in Europe and Asia, and so 
you have military, governmental and other users that are authorized to use the 
band.

[digitalradio] Unknown Digital signal????

Hi ,,, got a question for you guy's...  On 3.860.00usb to 3.863.00usb there is 
a digital signal.  Does anyone know what type or mode the signal is and 
possibly where it's coming from.  Comes on about 2400 Zulu and is annoying as 
hell  Hoping someone might know...  Thanks..  kc2axu

Andy,
I am sick and tired of reading the political comments and name calling
about ROS.  The discussion has devolved from a discussion (too long,
IMHO) about the technical aspects of ROS to personal attacks and
political discussions about which laws we in the USA should obey,
neither of which have anything to do with digital radio.

Can we please call a halt?  I get the digest form of the discussion
group, and have to wade through all these diatribes to find the one or
two useful messages in each one.  It didn't used to be this way.

Thanks and 73

The FCC specificly allows multiple-subcarrier transmissions on HF but bans 
"spead spectrum emissions using bandwidth-expansion modulation." 
Multiple-subcarrier modes don't have to increase the bandwidth as the signal is 
split into N parallel streams and each can occupy 1/N the bandwidth of the 
original.

The term "Spread Spectrum"  can apply to any mode that spreads its 
energy over more than the necessary bandwidth.   If we assume the necessary 
bandwidth to be equal to the signalling rate than anything other than single 
carrier modes technically fall into this category.

Even WSPR coul dbe considered spread spectrum!   Its 6Hz bandwidth is 
wider than the 1.5 B/s rate.Within the WSJT suite, JT65 is more of a spread 
spectrum mode, and outside Joe's suite, MT63 with its 2.5kHz for a few tens of 
Bits / second is even more extreme.

Strictly, CW is a three symbol code with source coding (variable length 
alphabet, like varicode) with soft decision coding, and mild FEC (operators 
interpretation of the code based on S/N) and some convolutional coding with 
soft decisions (matching characters received against patterns / words.

Once you start using soft decision decoding, error correction and mult- 
bit-per-symbol waveforms, it becomes a bit difficult to really call anything a 
digital modulation at all.   Especially when analogue processing is mostly 
performed digitally now, anyway

[digitalradio] Unknown signal ID ?

[jhaynesatalumni]

Around 2045Z Friday the 30th

Freq. 14076+1750

Mostly a steady tone, with several "clicks" per second, the
clicks being probably PSK transitions.

Hmmm.  I wish I had seen Skip's comment before I posted my last one.
How about this:

3500-3550 CW only
3550-3580 Any modes, with wide data modes starting just below 3580,
  and working down
3580-4000 Any modes <500 Hz.

Narrow data modes stay where they are now; wide modes grow down, CW
grows up, and they meet in the middle as needed.  The boundary between
suggested CW-only and suggested wide data could be 3540 (like
Bonnie's proposal) or 3550 (my previous suggestion), without it mattering
too much, since they grow towards each other as needed.

Re: [digitalradio] unknown garbage trashes QSO

[Danny Douglas]

There was only one station being heard on that 
frequency, the 6O which had been there for quite some time.  (And of course 
the ones that never get the word and call him simplex when he is listening up 
the band.  Whatever it was came up, and we immediately started loosing the 
6O contacts here in the states.

  from about 2130Z, there were a number of VE and

  legitimately
  tx there. 
   
  As well there were a number of VE5,VE6 and VE7

  So tell me, did you attempt to tx over them or

I just lost a QSO with 6O0N due to some trash 
coming up on 7.0637 thru 7.0644.  Can anyone identify what that junk 
is?  Perfect example of SSB and Digital modes on same freq, not

Re: [digitalradio] unknown garbage trashes QSO

[Danny Douglas]

I was on voice, split operation.  6O was transmitting that freq when this
buzz buzz came up.  Probably Pactor, as I dont work it, and can only assume
it was of that type.  He certainly didnt listen, nor ask using any other
mode, if the freq was in use.
