Hi Josh, Two things I can see in what you describe and sent: 1. In Fldigi there is another place that needs to reflect your 1500Hz audio frequency: in the configuration, tab MISC, sub-tab "Sweet Spot", PSK et al. need to be the same as in the Pskmail sub-tab. Can you confirm that this is the case. Please also note that is don't select reset to carrier I would strongly suggest you set the RSID receive to "search the entire passband". Reason being that without the reset to carrier Fldigi's afc (automatic frequency conrtrol) may take the audio centre frequency way off your 1500Hz on noise and interference and therefore any new RSID may not be listened to (the range is +/- 200Hz I think around the centre frequency unless the flag mentioned above is set). 2. Your freqs.txt file need to be like (starting at the first line of text): 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, 10146500,10146500,10146500,10146500,10146500, PSK250,PSK250,PSK250,PSK250,PSK250, USB,USB,USB,USB,USB, Hope this helps, 73, John
