I'm interested in using DRAWS to drive my FT-818ND for digital applications up in the microwave bands Eg. 904, 1296, 2304 MHz, etc (FT8, JS8CALL, etc) as well as a precise frequency reference for my LO. I understand that a DRAWS has a GPS on board with a 1pps reference for NTP. Is that 1PPS signal available for a frequency reference so that it can be used as a GPSDO with some additional parts? I'm currently using a Leo Bodnar Mini Precision GPS Reference clock to generate very stable reference frequencies between 400Hz and 810MHz. Eg. 1296 MHz = 2x576MHz + 144 MHz. A stable LO is essential for working up on the microwave bands. I just don't want two GPSs in my transverter. Ideas? --Konrad, WA4OSH

No GPSDO is implemented

The 1PPS Signal is on IO7, Pin 26 on the 40 pin header if you have an Oscillator with 1PPS Sync input.
