Here in the South of EI, there is an experimantal 4m "Simplexer" operational on 70.350 MHz (FM). This operates like a repeater except it operates only on one frequency. It listens on that frequency for any transmissions, records them and then re-transmits the recording on the same frequency. The maximum lenght of recording is 45 seconds. QSO's can be slow but it is pretty good when the other station is out of range or inaudible.
With the Sporadic-E season underway, this may be of interest to any OZ, 9A or S5 station when the band is open. I suggest that if any stations in those countries hear the Cornwall beacon GB3MCB, they should try a short transmission on FM on 70.350 MHz to see if the "Simplexer" is hearing them. It should be possible for, lets say, 2 stations in Denmark who cannot hear each other, to be able to work through the "simplexer" in Ireland on 4 metres!!
It is located on a mountain in the southern part of IO52 square, about 40 kms North West of the city of Cork and it is about 4-500 metres. GW stations in West Wales or G stations in Cornwall may be able to access it as well. (Polarization is Vertical, by the way).
