[Dstar] VK3RMM D-Star repeater

[Dennis Rogers]

Adrian,

       Dennis, N5VRP in Texas and am just curious as to your ADSL
upload/dnload speed in kbps.
This is in the ISP speeds of the service not the gateway. Looking to add
gateways in the Northeast
part of Texas. I am relocating there soon. By the way, it has been some time
now. Hope all is going
well there.
