Some observations this week...
Observation -- Earlier in the week, OHP unit in Midwest City using Turner Channel 1 (TG 42128) to contact OKC.
Observation -- keying-up sound at about 15 second intervals today (3rd september) about 6:30am on 855.9875. Received this from Tulsa to about MM 158. There was a morse ID but I am too slow and didnt get anything but the last digit: 6
Observation -- Tulsa was using an unusual FRQ for their control channel this morning: 858.9375. This FRQ is, of course, listed in the data base as an alternate primary control channel, but since I joined this forum in June '04, I have never heard them use any FRQ's for the control except 859.9375 and 860.9375.
