travaux punta

During the heavy earthworks around our radio site, our underground electrical cable has been damaged and the 4 wires have now an insulation problem.

Consequently, all our equipements are our of order since mid-february :
- our VHF repeater
- our meteorological station
- our 5 GHz Internet link 

For the same reason, the club station was unable to participate to the 2018 REF phone contest.

We are in touch with the company who made the works for Météo France who is building a new weather radar. We hope to be back as soon as possible.

TK5ZCG vignetteOur local UHF repeater TK5ZCG is now linked on out TKNet network. This repeater has been rebuild and uses now 2 commercial mobile radio PRM830 and a Kathrein duplexer, all retuned into the 70cm band.

The UHF repeater has been connected on TKNet on dec 6th 2016. The first tests are quite promising, but it seems that the antenna does not tilt down enough to cover the Ajaccio bay in good conditions. Both this repeater and the VHF repeater TK5ZCF are now linked through TKNEt and to Echolink (TK5KP-R)

Both repeaters need a CTSS of 88.5 Hz and are also transmitting the same CTCSS, so you can avoid local noise.

Here is a simulation of the coverage of TK5ZCG UHF repeater.

Here the details for both repeaters in the Ajaccio aera:

TK5ZCG
TX 430.150 MHz
RX 439.550 MHz
shift +9,4 MHz
CTCSS 88.5 Hz
Puissance 10 W
Locator JN41JS		 TK5ZCF
TX 145.6375 MHz
RX 145.0375 MHz
Shift -0,6 MHz
CTCSS 88.5 Hz
Puissance 15 W
Locator JN41IW

tk5zcf duplexeurAfter a long absence, the VHF repeater TK5ZCF is QRV again since 12/11/16. The location is in our hut in JN41IW. The duplexer has been cleaned and retuned, and so far no intermodulation or desensitization have been noticed. The output power is 12W.

Repeater acces in on channel R1x 145,6375 MHz (shift -600 kHz) and with TCS 88,5 Hz. It is linked to our TKNet network and to Echolink (TK5KP-R).

The next step will be to put a bigger antenna on a better mast.

Our Web  page has been hacked last week ! We were still using and old 2.5 Joomla! version that was not supported anymore since dec. 2014... The hackers  certainly used a security hole to hack our site. The site was only displaying a blank page.
Fortunately, i'm making regular backups and started a few months ago to convert the site into the latest Joomla! version.
So it didn"t took me to long to bring the site back online. There are still some things to do, though. In particular, the language translations...

station meteo puntaSince may 24th 2015, a weather station has been installed and connected to our TKNet on our hut in JN41IW at 780m asl.

The datas are transmitted via our 5 GHz link (9 km) and can be  seen in real time here.

First measures show that there is a huge difference compared to sea level and the maximum wind speed recorded so far is 137 km/h !
