CRG Rally
2009’s CRG Rally was held on 5th April 2009. The weather was exceptionally kind and it enticed a vast number of people to make the trip to Bottisham; thanks to all those – traders and visitors alike – who made the day such a success!
Talk – in was kindly provided by Cambridge Raynet, and Group Controller David Smith, G8IDL, gave a presentation on Raynet as part of the lecture stream. Other lectures were from Gavin Nesbitt, M1BXF on the CRG’s current technical plans; and from Neil Whiteside, G4HUN about the activities of the Camb-Hams.
Before the lectures started, CRG Chairman Rob Compton, M0ZPU presented former CRG Treasurer Jane Dyke with flowers and chocolates as a thank you for all her hard work over the years; and presented a DAB receiver to the retiring caretaker of Bottisham Village College.
This year’s members’ prize draw included a first prize of a Yaesu FT60e handheld, and two runner up prizes of APRS tracker kits with GPS receivers. The first prize was won by Olly, M0OLY; the two runners up were Graham, M0GRP and Ben, G6YQJ.

GB7NB D-STAR Repeater Operational (14th Sept, 2009)
The Norfolk Broads D-STAR repeater GB7NB went live on Friday 11th September at 15:00 and the first QSO was with M0KXK Ray.
GB7NB has an output frequency of 439.6875 MHz with the input 9 MHz lower at 430.6875 MHz.
The group’s website says that intial reports were good however but there is an issue with drop outs which may be due to mixing products from other transmitters on the site.
Phase 2 of the project will be getting GB7NB connected to the gateway, this is well underway with the PC Server already built and tested and the Icom G2 s/w loaded thanks to Darren G7LWT.
More details on GB7NB here, and the Norfolk Repeater Group here.
Presentation of CRG Rally Prize to Olly M0OLY (16th June, 2009)
At the May pie and pint we presented Olly M0OLY with a Yaesu FT-60r which was the first prize at this years CRG rally. Olly thanked the CRG for all the efforts and commitment to amateur radio in Cambridgeshire and hoped to win the first prize next year! It was fun to note Olly is a die hard Icom fan so presenting him with a Yeasu brought some smiles to those at the pie and pint.

Presentation of APRS Trackers to David G8IDL of Cambridgeshire Raynet (16th June, 2009)
The second and third prizes at the CRG rally were APRS tracker kits complete with GPS receivers to compliment the groups new APRS digi MB7UM. These were won by Graham, M0GRP and Ben, G6YQJ who both thought they would not utilise them and generously though others would have better use for them. To that end the CRG decided that Cambridgeshire Raynet would be a good beneficiary from them and as luck would have it David G8IDL the Cambridgeshire Raynet group controller was among the crowd the pie and pint so we stood him up to accept the presentation of both APRS trackers. David and all other Raynet members in attendance would like to thank Graham, M0GRP and Ben, G6YQJ (Ben was also there on the night) for their generosity.
