Just RXing to GB3VT VHF Repeater,
The following is took from "QRZ.COM"
GB3VT, RV58, Stoke-on-Trent, Staffordshire.
GB3VT is a 2 metre repeater located at 273 metres, 887 feet above sea level, QRA Locator IO83WA, in the City of Stoke-on-Trent, Staffordshire, United Kingdom.
The GB3VT repeater first became operational from its original site in December 1980 and has now been operational from its present site since 1995 and is co-sited with two other repeaters: GB3ST on 70cm and GB3SE on 23cm.
GB3VT transmits on 145.725 MHz and receives on 145.125 MHz. Both the receiver and transmitter use full decode and encode Continuous Tone Carrier Squelch System at a frequency of 103.5 Hz.
The Transmitter, Receiver and Repeater Control Logic are all-purpose designed and homebuilt, the timeout is currently set at 3 Minutes. The repeater also makes use of a home built 8 Cavity Duplexer, and the repeater delivers a total of 25 watts effective radiated power from a single colinear type of aerial.
To fully access the repeater it has always been a requirement of the station wishing to access, to transmit 3 to 4 seconds of good audio of at least plus and minus 1 kHz deviation. Stations using less than the required minimum deviation will fail to access.
In line with the now adopted United Kingdom 2 metre 12.5 kHz channel spacing, the repeater receiver has 12.5 kHz Intermediate Frequency Crystal Filters fitted and the transmitter peak deviation has also been reduced accordingly. To make the most of the narrow deviation, the transmitter reprocesses the incoming audio before re-transmitting it, the end product being a more uniform transmitted audio level. Because the repeater receiver has narrow filters fitted, stations that are found to over deviate are very likely to drop out of the repeaters receiver squelch circuit during loud speech peaks, in particularly that of the weaker received stations. If your equipment transmit deviation is not set up for 12.5kHz channel spacing, then the next best way to effect a temporary cure, is to "back off" from your microphone. If you are reported to be weak into the repeater, please do not be tempted to shout, as over deviation of your transmitted audio will not do you or the person that you are trying to communicate with any favours.
IMPORTANT, PLEASE NOTE:
The GB3VT repeater is no different than many other repeaters in the United Kingdom in so much as the repeaters operating frequency is shared with several other repeaters. To help stop co-channel interference problems from the users of other repeaters that share the same frequency as GB3VT, from April 2008 the repeaters transmitter and receiver are now both exclusive full encode and decode Continuous Tone Carrier Squelch System at a frequency of 103.5 Hz. To continue to access the repeater and obtain the full talkthrough facility, CTCSS by the user at a frequency of 103.5 Hz is now mandatory.
GB3VT WILL NO LONGER RESPOND TO THE OLD TONE BURST METHOD OF ACCESS AS WAS INTRODUCED BACK IN THE 1970s
This repeater is part of the UKFM Group Western and is operated on a completely voluntary basis, the receipt of any financial help is always most gratefully acknowledged. For further information with regards to the good work in the name of Amateur Radio that the UKFM Group Western does, along with information on ways to help towards the day to day running cost of this repeater, please visit: http://www.ukfmgw.org.uk/
Please also take a look at: GB3ST, GB3SE, GB3SM, GB3SX.
Signals from the repeater to me were 5/9+60db & i was about 30 Miles from the box. My TX/RX was an Icom IC2725 into a Watson W-770HB 2m/70cm Dualbander. My QRA was Stanage Edge DX Spot @ 432 Meters / 1417 Feet ASL, located to the South West side of Sheffield. Latitude: 53°20'21.73"N, Longitude: 1°37'11.74"W.
Hope you enjoy the video, Regards Dave M0AKB...
