I am using the usual parameters for 3sec dot QRS (500msec time scale and averaging of 5) The signal at this level is equivalent to 5nV at the input of the RX, but it is not characteristic of what reception would be like at distance, as I have attenuated the band noise as well!! The object was to see if the transmission pattern would be recognisable at threashold levels.....I guess it is. You are doing a great job fellas Cheers de Alan G3NYK Alan.Melia@btinternet.com
