G100RSGB by CARA

CARA will be hosting the RSGB Centenary Callsign G100RSGB on Saturday 2nd, Sunday 3rd and Monday 4th of November from the stations of G4ENZ (on the Saturday and Monday) and G0LGS (on the Sunday). The station will be active on all bands (except 60m) from 160m down to 70cm, on SSB, FM, CW and Data. We hope to be on the air for most of the 24 hours each day.

On Saturday the operation will be on HF on SSB, CW and Data with most of the SSB during the early afternoon. Sunday will see the main VHF/UHF operation, as well as some HF operation on SSB. On Monday the operation will be on HF on SSB, CW and Data with most of the SSB operation taking place between 10.00 and 14.00 hrs.

Follow the operations by monitoring spots on the DX cluster network, or on the Centenary Station Alerts page of the RSGB website, or on Twitter. The Twitter feed can be monitored at caranet.org – the CARA website.

JOTA 2013 – Report from Sevenhampton

For this year’s JOTA the Sevenhampton Scout Group camped in a field near the masts on Cleeve Hill. The Scout Leader Stuart G7IHN was assisted by Giles G0NXA who provided much of the equipment.

CARA made available an 80m loaded dipole which also resonated on 40m and this was strung between a convenient telegraph pole and a 42′ portable mast. Used in conjunction with a TS570 this offered good performance on both bands. The following morning a Capco SPC matching unit was added which extended the coverage from 80m through to 10m.

On 2m operations commenced with an IC271e feeding a mag mounted car aerial, coverage was never satisfactory. On Saturday, this was altered to use the pump up mast on Stuart’s Vauxhall Frontera to support a rotator and J Beam quad. Performance fell below expectation but some local contacts were made, so effort was concentrated on HF. This is perhaps to be expected as there was no testing prior to the event.

All the Scouts who attended the site were able to talk to other stations and several were heard talking to their parents about Foundation Courses. Stuart, the Scout Leader, is going to follow this up in the immediate future.

JOTA 2013 – Report from Twyning

Simon G6AHX, Tom M6TWR and Rick G6UZT assisted Adrian G0VLG in running JotA station GB0TWY at Twyning School.

They ran various laptops with Skype and path profile programs, and operated on hf and vhf/uhf. Adrian is a scout leader in the village and has a pump-up mast for his job. This mast was set up in the school playing field adjacent to the school. Rick had made a 2m/70cm aerial for the top and Giles produced a 40m dipole. Simon produced a PSU and rig for 2m/70cm.

They had visits from various local groups staggered by an hour each. This allowed the visiting scouts to speak with GB2SSG and GB1GLO during the day until 1600 when the station was closed.

G100RSGB

Plans for CARA’s activation of the RSGB’s Centenary Callsign G100RSGB on 2nd, 3rd and 4th November are well advanced. Martin G4ENZ will host the station on Saturday 2nd and Monday 4th assisted by Derek G3NKS, Ian G3TDT and Iain M0PCB. Stewart G0LGS will host the station on Sunday 3rd assisted by Matt 2E0MDJ and Nick G4WLC. Twenty-four hour operation over the three days is being planned. More details nearer the time.

JOTA 2013 – Report from Hatherley

For this year’s Jamboree on the Air (JOTAJOTI) Simon, G4SGI, provided an HF receive station and a 40m transceive station at 1st Hatherley scouts. Doug, G4IGN, kindly provided him 40m portable vertical antenna.

This was some of the hardest work of the year, but also the most rewarding because of the enthusiasm from the scouts, their energy and interest in what was going on. At 1st Hatherley (@1stHatherley) almost every scout who wanted to talk on the radio did so, and we had several expressions of interest from both scouts and parents on how to get licensed.

The transatlantic rowing team (@OceanRowing2013) were also there and had a lot of custom from the scouts. Watch this space for further developments regarding their ambition to include HF amateur radio on their trip.

The CARA meeting on Thursday 17th October 2013 featured three short talks by club members.

Iain, M0PCB, described ClubLog – a website for analysing your log.

Nick, G4WLC, talked about  “Excursions with Elsie” – Elsie being a van he has equipped for use as a portable shack.

Simon G6AHX related his experiences working through satellites.

 

 

September Meeting – Report

Chairman Doug G4IGN talked about the new club project: a computer-radio interface unit for data-modes built from a kit. Several members expressed interest in buying and building the kit.

The antenna analyser built from a kit earlier in the year was also on display at the meeting.

Summer Garden Party – Report

Some 15 people attended the CARA Summer Garden Party on Sunday 25th August kindly hosted by Rosemary and Ken G3XSJ at their delightful QTH near Wotton-under-Edge. The gathering was blessed by warm and sunny weather and plenty of excellent food. So a good time was had by all. Our grateful thanks go to Rosemary and Ken for their generous hospitality.

August Meeting – Report

The meeting on Thursday 15th August was really great, very well attended, with superb data-modes demos and displays. Colin G3VTS had his TenTec Jupiter receiving 20m data signals with the aid of a small magnetic loop constructed for the occasion. Stuart M0GPC showed a range of early packet radio controllers. Paul M0UTC demonstrated various data-modes from his car. Jon M0JMM displayed his portable hf and vhf data-modes station and exchanged DRM pictures with Paul on 2m. As a side show, Derek G3NKS had a couple of tables selling “Silent Key” stuff. Great interest was shown in all the displays and much chat took place; it was clearly a very popular meeting – there were 39 names in the attendance book. We were please to welcome visitors Mike M0JVP and Arron 2E0CUX. Many thanks to all who brought along equipment and to Andy M0JLY for manning the refreshments bar.

August Meeting – Natter Night Featuring Data-modes

As usual, our August meeting is a Natter Night with a theme. This year members are invited to bring along equipment relating to data-comms modes to put on tables for display and for demonstration if so desired.

We look forward to seeing, among other things, computer-radio interface units and laptops running data-modes programmes. Paul M0UTC has kindly agreed to bring along his mobile set-up and demonstrate PSK31 and may be DRM (digital pictures) – regarding the latter, he asks if another member could set-up a DRM station in the building so that pictures could be exchanged between the two of them. Any offers please?

Come along and chat to other club members, introduce yourself to our newer members and enjoy the displays and demonstrations. Tea, coffee and biscuits will be available as usual.

The meeting will take place on Thursday 15th August, 7.30 for 8pm at the Brizen Young People’s Centre, Up Hatherley Way, between Morrison’s and the Shurdington Road, Visitors and prospective members will be made welcome, as always.
