SP8WJT/HF8V - RED ARMY RADIOTELEGRAPH SIMULATOR - SP8WJT/HF8V TIME AND FREQUENCY STANDARD STATIONS ver. 4.29 OVERVIEW: Time and Frequncy Standard Service originated in early days of radiocommunication, althought it was used earlier in landline telegraphy. Some of these stations were created when "real" telecom was liquidated and transmitting facilities became available (GBR -> MSF etc..). In more ancient times it was 5 minutes skeds before full hour and it was just part of "programming" of big telecom Radiotelegraph stations the same as it was on broadcasting stations. Such station would have point-to-point service or meteo broadcast first 50 minutes of the hour, then 5 minutes callsign tape was run, and time ticks were sent in special system up to full hour. Then again, another service was run. For details please see sources. "Equal" frequencies like 10000 kHz became dedicated TS frequncies only in middle and late period of radiocommunication, in fact it is old diplomatic and meteo wave 30m, thus not only TS stations can be heard here. Since some stations never used CW identification, those are represented by anonymous N0N or just undefined tics. SIMULATION: 3 specilized functions are used plus some general purpose functions. Simulation is still not 100% true, I'm not bothered to simulate full working cycles of these stations or real durations of impulses, althought it can be done later. Also ticks are not 1 second calibrated (it was in earlier versions), it is just to heard it and recognize it by ear. ================================================================================================================================================ FREQ C/S USED TIME CONSTRAINTS FUNCTION USED REMARKS ================================================================================================================================================ 16 GBR H: 2,8,14,20 send_times, ts2 'GBR TIME' sno [***] 16.6 DFY 1155-1200 2355-0000 ts2 19.9 --- cont ts WWVL 26 --- cont ts NPG 26.1 NPM 2355-0000 ts2 (1928) 40 JG2AS cont ts2 43 NPG 1455-1500 ts2 46 NBA 0355-0400 1755-1800 ts2 (1928) 50 --- cont ts OMA 56 NPO 0255-0300 1355-1400 ts2 (1928) 60 JJY cont ts+ts2 callsign at H+15 60 MSF EH ts2 sno -
