   ** UOSAT HF BEACONS EXPT.  **

   The UOSAT spacecraft  HF  antennas  release  pyros  were
 fired at 02:37 gmt June 21 and the 7,14,21 & 29 MHz beacon
 activated under on-board computer control.  Strong signals
 were received  at  UoS  on  21.002  MHz with the beacon in
 alternating morse/carrier transmission  mode.   The  morse
 speed was  switched  from  20 wpm to 10 wpm after second 2
 minute test.

   No signals on 7 & 14 MHz heard - heavy qrm.  Signals  on
 29.510 MHz expected but not received at UoS.

   Due to minimal power drain, it is anticipated  that  the
 21 & 28 MHz beacons will be now be left on permanently.

   The synthesiser system will be checked out next orbit  -
 0539 gmt June 21.

   Reports of reception of the beacons most useful.
