SiRF format not working in Alpha 26 (worked ok in Alpha 23)

[webvan1999]

I've been experimenting with old Bluetooth SiRFStarIII receivers and was able to read data in Alpha 23 version using "SiRF" format input, however that no longer works in Alpha 26. Is there a setting I'm missing somewhere ?

And for some reason in Alpha 23 I can't get the RTCM 3 feed from the base station decoded...unlike in Alpha 26 (checked with both RTCM2 and RTCM3). Thanks !
