SP8WJT/HF8V			  			   - RED ARMY RADIOTELEGRAPH SIMULATOR -						 SP8WJT/HF8V




								  UNDEFINED DF NET 170 




ORG: A-140


OVERVIEW:

   This is fictious network, but a lot of his type DF networks existed during 2WW period in many
  military organisations of many countries. USA, UK, Wehrmacht, Japanese Army, to mention just a
  few. Unfortunatelly small radiodata survived since it was rather confidencial matter. 
  But basic scheme is pretty same for all this class of stations. HQ is sending coded frequency 
  and DFing stations performs DF and sending back coded azimuth data. I used my simply invented
  format for this network.

FORMAT:


1. radiopeleng request. DF HQ just sending encoded frequency.

	HCA DE XFN FFFFF CFM K  			


	F - frequecy, leading zero if 4 digit 
	

2. answer for radiopeleng request. 

	FFFFF 3AAAC 4tttt

	F - frequecy, leading zero if 4 digit 
	A - azimuth 0-359 
	C - class of radiopeleng
	    1 - A class
	    2 - B class
	    3 - C class
	    4 - radiopeleng impossibble, station not head
 	    5 - radiopeleng impossibble, station too week
 	    9 - DF equipment out of order
	t - time of radiopeleng  

	Group identifiers 3/4 and time t are not enciphered.
