UK astronaut Tim Peake KG5BVI / GB1SS

On Monday, April 18 at 3:56 pm BST (1456 GMT) UK radio amateurs will have
the chance to listen to Tim Peake GB1SS transmitting on 145.800 MHz FM from
the International Space Station (ISS).

All you need to hear Tim is a 144 MHz handheld radio, such as the popular
£16 BaoFeng UV-5R VHF/UHF transceiver. If used outdoors you should be able
to hear Tim with just the tiny antenna supplied with the handheld. If you
have a 1/4 wave whip you will get better results.

In the UK we use narrow 2.5 kHz deviation FM but the ISS transmits on
145.800 MHz with the wider 5 kHz deviation used in much of the world. Most
base station and mobile radios can be switched been wide and narrow
deviation FM filters and for best results you should select the wider
filter. Handheld radios all seem to have a single wide filter fitted as
standard.

As a result of Doppler shift the 145.800 MHz ISS signal may vary by +/- 3.5
kHz during a pass going from 145.835 to 145.7965 MHz. Many FM radios can
only tune in steps of 5 kHz, with such equipment you may get best results
by selecting 145.805 at start of pass, then 145.800 and finally 145.795 MHz.

Not got a VHF radio or not in the UK ? You can tune-in to Tim Peake online
from anywhere in the world using the SUWS amateur radio WebSDR receiver
located at Farnham near London http://websdr.suws.org.uk/

There will be a live video webstream from St. Richards College start 2pm
