I'm not sure why you are using DATA A instead of AFSK A, but ... If you don't want MMTTY to transmit on a different frequency from your receive frequency, turn NET on - in AFSK, that will force the TX to follow the RX. Also, you should tell MMTTY that your preferred frequency is 1275 Hz. To do this, set your HAM default to 1275.
A general rule for AFSK is: while S&P, turn NET on and AFC off; while CQing, turn NET off and either turn AFC on or leave AFC off and use RIT instead for off-frequency callers. Some software will switch the NET and AfC settings for you automatically between run and S&P modes. If you do use AFSK A instead of DATA A, you will have to change the K3's PITCH setting to 1275-170 from the default 2125-170. 73, Rich VE3KI HS0ZED wrote: > MMTTY is working fine in DATA A (AFSK) receive is no problem and > transmit too provided I use 2125Hz. > > I would prefer to use 1275Hz but when switching to transmit MMTTY keeps > jumping to 2125Hz. How to stop that? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
