I use a HAL DXP38 HF modem for RTTY, too, and have the same issue as K4FJ.
According to the HAL DXP38 Interface Specification, the modem outputs to the
PC a tuning offset value (+/- 100 Hz) and the value of four tuning bars (T1,
Mark, Space, and T4) in RTTY mode. Presumably these are the data that drive
the WriteLog scope display. However, a clarification of exactly how
WriteLog interprets and presents this information would be most appreciated!
