Balloons (HAB)

A quick update on the status of the SUWS microwave SDR
http://websdr.suws.org.uk/

10 GHz - the Octagon PLL LNB based system is working well and now has
the correct frequency labels on the scale (rather than the RTL dongle
tuning range).  The Octagon does drift up to 30 KHz high with
temperature which is not bad considering it is unmodified and mounted
on the mast,  and you can get an accurate frequency calibration from
GB3SEE which is visible at all times on 10368.850.  We have seen some
very interesting propagation effects (both RS and tropo) with GB3CCX
and GB3LEX was audible last week during the lift.

1.3 GHz - the SPF pre-amp is now mounted at masthead.  There is some
small frequency drift from the RTL dongle but GB3FN is very loud at
all times and GB3MHL / GB3DUN are now audible with the any improvement
in condx or aircraft scatter (Heathrow lies directly on the path to
MHL).

144 MHz and 432 MHz - We are trying a new type of mixed mode helix
antennae on both bands to improve satellite and HAB reception and it
seems to be working very well - see
