[digitalradio] frequencies for ROS

2010-03-06 Thread Edward 
i will not elaborate on the on going debate of ss. just do a google seach on 
the theory of spread spectrum. that should anwser all ur questions. i've been a 
two way radio repair tech and system installer for 49 yrs so i know what ss is. 
my question is this: what frequencies are being used, in the us or over the 
pond, for ROS. i would like to monitor some ROS sigs.
thanks all

google or search spread spectrum. the term speaks for it self. FREQUENCY 
hopping several times per second. the receiver tracks it. specially built 
radios. military first used it to foil the enemy on eaves dropping. now it is 
used commercially. ham radio freq does not change, just the mode of operation. 
how wide? i don't know. that's why i'd like to know the freqs so i can listen 
and come to my own opinion.

  Yes, I was watching Phil - condx are poor between us. The RS ID is very
  sensitive so you did cause Multipsk to switch from PAX2 to PAX when you
  called.
 
  Thanks for trying.

All,
   
I have Multipsk's responder setup as an experimental pseudo
  mailbox
on
3598.0 USB. The beacon is running in PAX2 mode and will accept
connects
in
both PAX and PAX2 (Multipsk will switch modes automatically if you
   enable
your RS ID). The responder also works in PSK63/250 ARQ and 300
  baud
HF
Packet.
   
It does not work like your typical PBBS, but it does allow
  stations
to
connect and read the messages that the user posts in the
  responder.
The
menu
system is limited to L for LIST messages and Rx for READ
  message
number
   
x.
   
To connect, switch Multipsk to PAX/PAX2 modes and make sure
  UNPROTO
is
clicked. Put your call in the SENDER box and set the DESTINATION
  to
   K2MO.
Click CONNECT. The system will respond with a greeting and how to
  use
   the
menu. All of these items are on left just above the waterfall.
   
PAX is sensitive MFSK mode based on Olivia. Please give it try.
   
Thanks,
   
Tony -K2MO
   
   
   
   
  
  
  
  
   
  
   Suggested frequencies for calling CQ with experimental digital modes
  =
   3584,10147, 14074 USB on your dial plus 1000Hz on waterfall.
