      Dear friends,

      All is still on for Saturday's flights.  Current predictions indicate a short distance flight for BASE 68 with a landing within a very few miles of the launch site.  BASE 69 will burst at a lower altitude and will land southeast of the launch site, but within twenty miles.

      On BASE 68: To clarify on the EBE radios.  The uplink to the balloon is 144.34 MHz (balloon receiving radio).  The downlink is on 446.025 MHz (the balloon transmits down to the ground on this frequency).  The radios will be operating under a direct net control with the call sign WB9SA.  APRS call signs of WB9SA-11 and 12

      On BASE 69: Here are additional details for the 10 M beacon:

      Callsign is:  WB9SA-1

      28.2216 MHz is the center frequency so best copy would be to tune 28.220 MHz USB and it will be about 1600 Hz in the waterfall display on dl-FLdigi.

      Sequence as follows:

      - Morse Code:  WB9SA  XXXXX  (where XXXXX is altitude in meters in Morse Code)
      - DominoEX22  
      - 110 baud ASCII RTTY

      Every 5 minutes it will also send the lat/lon in CW after the RTTY.

      $$WB9SA-1,4,20:18:00,3424.52,- 08648.76,348,08,5.88,37*2D

      $$<callsign>,<sequence #>,Time UTC(HH:MM:SS),Lat(DDMM.MM), Lon(-DDDMM.MM),Alt(meters), Satellites,Battery,Temperature (Deg. C)*<checksum>

      ATV will be on BASE 69 with horizontally polarized antenna at 434 MHz.

      APRS call sign of WB9SA-13

      Best wishes for successful contact,
