VARA & The PSK-MAP


Graham
 

Trials are under way, linking  VARA to the  PSK-Map. via the  varAC  chat application 
listing as VARAC ,

The ADIF inclusion remains  in a rather quaint Mexican standoff 
over singular  modulation definitions and designations , be it that  simple,  
eg olivia has a phase component in the  modulation, hence it  needs a  linear 
transmission path , listed as mfsk , but with   phase angle as well  , could be  listed as psk 
fsk , only  2 tones ?  chirp, is  also  fsk with  sliding tone .. and so on -


14.105 +/-   showing  quite  high usage, noting the  map is only  showing spots from the  test version
with limited  distribution , but still a  insight into  use 

Appears the  next release /8 will  have the  psk-map  web linkage 

New version of the modem  , provides  TUNE function from the  varAC  application
and  control of the  power level as well as  many new features,

Never having heard of the psk map et al but as I do own a copy of Vara and am interested would you mind providing some links to start me off?

The PSK-Map as its name suggests was developed, when psk31 was the  only  mode in use , the  map sought, to  provide a  spotting 
facility, to  show the  users,  cq's and  qso's , long before reverse beacons  etc 

since then its expanded to provide a communal data base for  modes used  on the  ham and cb bands , the data base provides  a one year storage of spots
and can be accessed  via html  sql  , a file is exported that  opens in MS EXL

This is the  TEXT  qso front end  , coded by 4z1ac to  front the  VARA modem , quite simple to  use, now provides CAT control 
for  most rig's , The VARA modem remains compatible with  winlink , vara chat and the  varAC  app , a beacon 
mode has been added to the  modem along with a  CQ function , accessed via the  Chat apps 
provides a  live test ARQ qso , similar to AMTOR in days of old, but at much reduced  s/n , I used to  need  ~ 200  watts 
to  work  usa east coast with  Amtor on 7 mhz , the  same with  Vara  20  watts  using the  same  40 ft vertical.
