Hi Melanie

Thank you very much for your reply, after reading your reply and working through it with a selection of received data, I can now understand how it works,
For some reason, my brain went awol last night whilst reading the serin2 description, I got myself mighty confused!!.
again, many thanks for the help Melanie.


Ps. just for info, I own an ex-military fitted for radio (FFR) landrover and the 58kk90 was the military registration number, thats where the user name came from.
