U3S and strange sudden changes in locator

Hans Merz All Messages By This Member #106164 I am a happy user of the Ultimate 3S. I use it mostly for WSPR. I use it now for about a year. Almost every day and then about twice a day my locator sudenly changes. I see on the screen of the U3S during WSPR transmission that it is sending an other locator. I think that it is generated by the program of the U3S some how? ?There are always the same changes in Locator. It is or JE36 or IN73 as "ghost location". My Locator settings for the Ultimate 3S are: ?Xw 0; X2 0; Yn 0; Iv 1; TxS 15. My location is JN23(vj) for the past months. But when I use it "at home" JO22(hi) the same changes with the same "ghost locations" happen. I use the GPS receiver QLG2 in combination with the U3S. Has anyone experiences like this? Or hints what is happening? Best regards, Pa3AAW ?/ Hans Merz

Hans, In the configuration of the U3S is a setting for "checksum" this prevents a corrupted NMEA sentence from changing the locator. But it can not be set if you want to send your locator mobile. 73 Alan G4ZFQ
