Hi, With the current use of both 10148.25 and 10148.50 I am having trouble with my server. I have a 500 Hz filter on the server and the 10148.50 qrg falls within its range. Naturally 10148.50 isnt decoded but it destroys weak frames received on 10148.25 anyhow. A DCD wouldnt work either as the upper qrg is just a little to much offset... I don't see a point of using two frequencies on 30 meters, if there is such a requirement then can we pse move them a bit further apart? I suggest that we standardize on using 10148.25 for all servers, that way aprs pos and pings can be received by more servers on the same qrg. 73 de Per, sm0rwo
