GB3CQ – 10 metre UK repeater.

G4NSJ MENU

GB3CQ
Ten metre repeater.
Worthing, West Sussex UK.

Technical Information:

Licensed since 28th May 2021 and first switched on at 3pm on 10th June 2021. This coincided with excellent propagation conditions and enabled stations over most of Europe to be heard on the repeater.

GB3CQ is the only operational in-band 10 meter repeater in the UK. It is experimental and the repeater group are constantly trying out different hardware.

RX: TYT TH-8900
TX: Yaesu FT-8900R
Logic: ID-O-Matic IV see text
TX Antenna: Sirio GPE 5/8
RX Antenna: 1/4 wave GP
Power Out: 11 dBW
Repeater Keeper: G4WTV
Location: IO 90 SU
Repeater Output: 29.620 MHz
Repeater Input: 29.520 MHz

Currently, it uses a Yaesu FT-8900r for TX and a TYT TH-8900 for RX. Most, if not all 2 meter and 70 cm repeaters, use a single antenna for TX and RX with Duplex Cavities to enable single site use. This is impossible on the 10 meter band with only 100kHz split, so the TX and RX sites are separated by approximately 2 km. All 10 meter repeaters operate in this manner and have some sort of audio link between the two sites. Some use an Internet link and others use UHF or Microwave radio links. The repeater group is currently trying these various link methods.

The Logic, which controls the Transmitter and allows for periodic (20 min) indents in Morse, is an ID-O-Matic IV from hamgadgets.com and provides many useful facilities. There is also provision for CTCSS and Voice ident, although this is not currently in use.
