Welcome to the N7TWB Amateur Radio Station.

I operate the N7TWB/R repeater on 447.95(-)MHz in Peoria, Arizona

This is an open repeater with good coverage of the western part of the Valley.

100 Hz PL tone is required to open the receiver. 100 Hz PL is also transmitted.

Anti kerchunking is usually enabled, so your initial transmission must be
over 2 seconds long if the machine has been idle for a while.

Station equipment is a Motorola Radius R-100 UHF Repeater,
a Micro Computer Concepts RC-1000 controller, Celwave 638-6 six cavity duplexer,
& Diamond F718A 11.5dBi gain vertical antenna at about 16 feet AGL. (to be improved)


Repeater is back on line and being tested

Theoretical repeater coverage map is shown below for a mobile installation.
Of course, buildings & below grade roadways cause local holes.
