Kempton Park

All,
Our next meeting is this Wednesday the 22nd April. We will be holding a short quiz with the usual refreshments...  A big thank you to all those who made it to Kempton Park for the rally on Sunday. Our stall was a great success with lots of visitors Thanks to Tony for persuading so many of them to part with their money!  

We seem to have settled on the 2M frequency of 144.500Mhz for club use so give a call and maybe you can scare up some SHARES DX 

We look forward to seeing all those who can make it this Wednesday.

Data Modes Evening

The next club meeting of SHARES will be on Wednesday the 8th April. 

We will be running a demonstration of data modes on the HF bands (RTTY and PSK31) so this is a good opportunity to see what is required to work these modes and discuss the theory and practicalities of operation.

RTTY mode is now quite old and started in the days when people were using mechanical teleprinters Yes they were as heavy as they looked!). There is no error correction on this mode but like morse it tends to get through most of the time. Of course we now use computers instead of teleprinters..

For more about RTTY have a look at -

RTTY

PSK31 is more recent and is phase shift keying. It was designed as a modern replacement to RTTY and occupies a bandwidth of just 31Hz. Its growing in popularity...

We have booked a table for the Kempton Radio Fairs rally on the 19th April so we can discuss our preparations for that and of couse there will be tea and biscuits and maybe a raffle.
