Product Overview
The GPS-710 is a custom built, uncluttered, plug-and-play solution for adding a stand-alone GPS to your Kenwood TM-D710 or RC-D710 radios. It uses an excellent 20 channel SiRF-III GPS chipset (with WAAS, ENGOS, and MSAS augmentation) that can acquire GPS lock from a cold start in well under 60 seconds. The active internal antenna has proven to be extremely capable of maintaining GPS lock, even in very unfavorable mobile installations. The GPS remains powered even while the radio is off, and provides data immediately when the radio is powered on - instantaneous position lock. The GPS-710 draws about two-tenths of a Watt from the line, and does not present a significant standby drain to an automobile battery.

As you can see from the photo below, the GPS-710 is hidden well behind the Operation Panel. The GPS-710 is attached to the Operation Panel with automotive-grade "high bond" adhesive tape, designed to maintain a strong bond in temperatures up to 200F, which is well above the operating temperature limits of the radio. For anyone not wanting to mount the GPS-710 to the back of the Operation Panel, optional separation kits (6" and 24") are available.

The shielded serial jumper uses molded right-angle connectors with an integrated strain relief. The data jumper uses a double shielded cable that follows the Kenwood design for signal shielding. The wires are cemented into the RJ-45 (CAT6) connectors before being crimped into place and the resulting connection is extremely reliable. Every GPS-710 is individually tested on a TM-D710 before packaging.

The GPS-710 is FCC Class B certified as a peripheral device to the TM-D710/RC-D710. The RJ-45 jacks on the GPS-710 employ high quality EMI filters, so additional ferrites are not commonly needed. An open "pass-through" 2.5mm serial jack is provided, as can be seen below, so that an external device can be attached to the TM-D710 and/or GPS-710 serial output signals. An example of attaching the GPS-710 to a laptop (APRSISCE, APRSPoint, UI-View32) is given here.

The mounting bracket and COM port are both completely usable with the GPS-710 installed.

Telford Hamfest 2013

Sunday 1st September 2013

Admission £3

THANKS TO ALL VISITORS & HELPERS.
A VERY ENJOYABLE DAY IN 2012

Visitors and Traders comments:

"...all the hard work that went into producing an excellent radio rally today. A good choice of traders and club stands made for a very enjoyable day..."

"...I was with the xxxx stand at the Telford Hamfest yesterday. I'd just like to say that we had a very enjoyable time there, and the various officials were particularly helpful and friendly..."

Telford & District A.R.S. are proud that the 7th Telford Hamfest is taking place as usual on the first Sunday of September 2013, co-ordinated with the famous Ironbridge Gorge Museum Trust’s Staff at Enginuity. We are also happy to add that the entrance charge remains at last year's rate and exhibitors' prices have remained static for the past six years. A list of Exhibitors in 2013 (and 2012) can be found on the left hand Navigation Menu.
The HamFest opening time is 10:30 as usual.

In 2011, we found space to introduce a small 'Flea Market' in the outdoor area. We hope more sellers will take advantage of this facility this year. Tables will be available at just £9 each on a first-come-first served basis. An advance phone call to Martyn on 01952 255416 would be very helpful in planning space.

Enginuity, right next door, is a fantastic ‘Hands on Technology’ Centre, which invites visitors of all ages and interests to roll up their sleeves and get involved, with a special admission discount of about 30% for all people attending the Hamfest.

The Committee and club at TDARS are working hard in preparation for September's event.The site offers more than just a traditional radio rally venue and we have developed a good reputation both for our exhibitors, but also the location and local attractions. The 2012 event saw us maintain the same visitor levels as previous years, testament to the quality of traders and venue. Last year we booked another eminent speaker in the adjoining "gallery", Stuart Wisher G8CYW, for a presentation and demonstration of Light Communications. This year an invitation has been extended and accepted by the very well known Rob Mannion G3XFD, who is retiring this year, and has chosen
"My Adventures as Editor of Practical Wireless" for the title of his presentation. As usual, attendance is included in the admission price.

The venue is just a few minutes (4 miles) journey south from the M54 (J6) at Telford and from other trunk roads.(Main parking Postcode TF8 7DU). See location tab for detailed directions.
FREE PARK AND RIDE FOR 2013. This regular 12 minute service operates near the roundabout at the top of Jigger's Bank (A4169 - postcode TF4 3QE), which is the normal route to Enginuity. It takes you almost to the door. Return pick-up is on the main road opposite the site, by the Enginuity venue. The free parking at the Aga works is still fully available to visitors.

From feedback and given our experience in 2012, we anticipate most available space will again be booked prior to the event. Our previous experience in organising radio rallies will ensure all arrangements will go smoothly and efficiently, and a good day will be had by all.
