| 05/01/2011: The All New GB3IP! | G7PFT |
| GB3IP is now in its new home, a nice warm cabin and antenna 30m AGL with mains power! It sounds trivial but we've been working on this for about five years with setback after setback but its all finally there! Technically the repeater is pretty much as it was with some minor audio tweaks but there remains some issues with QRM which is as yet undiagnosed. The cavity filters could do with a tune-up too as they vary according to temperature. The antenna is fully rigged but in the move the radials became damaged so we're currently working on getting a new set which should improve TRX performance quite a bit too! | |
| 12/02: GB7IP - Digital Voice Repeater | G7PFT |
|
An application was submitted on 10/02 for a digital voice repeater GB7IP to be located nr Cannock. The keeper will be Trevor, M0OML and the site enjoys fantastic line of sight to most of the region so even on 70cms there should be excellent opportunity for local D-Star working. The repeater will be generically a GMSK regenerative repeater which will allow other digital voice protocols such as P25 to be used in the future. We are working hard to develop a new repeater controller/gateway solution for D-Star that will provide some very innovative features such as repeater hand-off for mobile stations that allows multiple repeaters to share the same spectrum very efficiently. It should be noted that the current 70cms frequency pair for D-Star repeaters 439.9125 (rep output) and 433.9125 (rep input) will change in the future following ongoing work by Ofcom and the ETCC. Should GB7IP be allocated this channel initially please be aware that this will change. Local interest in D-Star is increasing rapidly with new Digital capable radios appearing week by week. If anyone is interested and would like some pointers then please feel free to contact me 73 Jon G7PFT | |

| 04/02: D-Star... | G7PFT |
|
Following some interesting dialogue locally, I am keen on implementing a D-Star repeater solution locally. I am currently in dialogue with the ETCC about how this is best achieved. My new Icom 2200 will be arriving this week, so there will be at least someone to have a QSO with! I am looking to connect GB3IP to both analogue and digital modes as a way to encourage users to experiment with digital and to ultimately transition from analogue to D-Star. Watch this space over the next few weeks for more info... 73 Jon G7PFT | |

| 31/08: MB7IP now QRV! | G7PFT |

Thanks to the efforts of Bill G4EIT, Trevor G7PVS, Trevor 2E0OML and Peter 2E0VTS the 2m APRS digipeater became operational at 13:00 on 30/08. Initial indications are that coverage is much better than expected - the detail of which can be seen here. Good coverage from Telford to Burntwood and Stoke to Billingsley/West Brom has been seen already, with DX seen as far afield as Oxford and Cheltenham. A big thank you to Andy M0CYP for his assistance in integrating the system with the existing APRS network. More detail, and pictures will be added to the website shortly. The TNC used is a Kantronics KPC3 along with a Maxon PM100 VHF radio on 144.800Mhz. The Maxon radio was specifically chosen because of its exceptional sensitivity (0.138uV @ 12dB SINAD) and good adjacent frequency rejection. The antenna is mounted at 5m AGL on a stand-off bracket generously fabricated by Allan G4NJR. None of this would be possible without the people named above so my thanks go to them for their continued commitment to the projects. 73 Jon G7PFT | |

| 17/07: APRS Digipeater - MB7IP... | G7PFT |
|
Further to my last update announcing the successful licensing of the 2m APRS digipeater to be co-sited with GB3IP, its callsign has now been changed to MB7IP to reflect the APRS over 'IP project. Thanks to the ETCC and Rod Wilkinson at Ofcom once again. It is hoped to get the APRS digipeater on 144.800 Mhz active during the week of 23/07 but more info will be posted here as things progress. 73 Jon G7PFT | |

| 10/07: APRS on GB3IP... | G7PFT |
|
Taken from http://www.ukrepeater.net: APRS EXPERIMENT on GB3IP(9 July 2007) A proposal has been received for the introduction of APRS (Automatic Position Reporting System) on the GB3IP repeater at Stafford. APRS is a system developed by Bob Bruninga, WB4APR which uses amateur radio to transmit position reports and messages between users. The solution proposed works by a mobile user sending a data "burst" at the end of each over. This data burst is in a compressed format (MIC-E) that takes only about 300ms and is transparent to normal repeater operation. The decoded data is then gated onto 144.800MHz (and then subsequently other digipeaters and IGates) for integration into the APRS network. The simplicity is the beauty of the idea, requiring a simple device on each mobile to encode the GPS location into an AX25 FFSK packet. Fortunately one of the most popular types of APRS tracker modem, the TinyTrak supports these features and is available for around £20. The operator behind this idea is Jon Richardson, G7PFT and Ofcom have agreed in principle to the project being adopted. | |
