I played around with resetting My Kenwood TS-870 RIT by inserting radio control characters in the F1 CQ function key (ahead of the CQ message). Works fine until you go to use the Auto CQ Mode with F1, then it sends the F1 radio control characters as well.
I changed Auto CQ to use F2 which I hadn't progrmmed radio control charctors into. Works fine this way. But--- In the Random CQ mode if one programs the RIT reset control characters into each of the four F keys, which one would have to do since the first CQ message is picked randomly, then the control characters are sent with each CQ. Is this taken care of in a setting using <Cntl J> or is it something to put on the wish list? Maybe someone has already asked the question? Page 47 of the Version 6.71a manual describes how to format these control messages. For my radio, when programming F1, I used <Cntl P><Cntl C>SRS=RC;<Cntl P><Cntl D>TEST \ TEST. This sends control charactors to the radio just before sending out the CQ. (RC is the RIT Clear cntl character on the TS-870) I believe other function keys such as Cntl Fx and Alt Fx can be programmed to cntl the radio without sending out CQ etc. 73, Don, W6OA
