Now I’m setup on 4m from the home QTH (see Dual Band 4/6m Moxon Antenna Experiment) I’ve been able to explore a repeater oddity just down the road from me called the “Tring Parrot” in IO91, known officially as GB7FM.
First of all it operates on 4m, there’s not too many repeaters on this band and secondly it’s a simplex repeater. This means you broadcast your message, which the repeater records and then plays back at the end of your transmission, hence the nickname!
I setup the Icom 7300 to broadcast the correct CTSS tone on the simplex frequency and it works. Being a 4m repeater there’s not too much activity and no one has come back to the few calls I’ve put through it yet (update: see bottom of page for QSO video). My main motivation was just to see quite a different form of repeater to the standard half-duplex that we’re all used to.
