Sorry - I believe it also needs to be able to measure the frequency of the audio tone on the line...
Mark - N9WYS -----Original Message----- From: Repeater-Builder@yahoogroups.com On Behalf Of N9WYS My "helper" told me that I need to start looking for test equipment - he's taking a different job and wont have access to the equipment he does now. Inasmuch, what is the test meter called that you use to measure the signal level across/on phone lines? I'm told that I need one that measures in dB, I believe. Thanks! Mark - N9WYS -----Original Message----- From: Repeater-Builder@yahoogroups.com On Behalf Of Dan Blasberg Most of the radio circuits that i remotely test and we (Verizon) engineer are 0, -16 circuits, meaning that the from the telecom interface we are looking for a 0db signal on the transmit side, and when it gets to the other end at the interface card at the station the signal will be -16 db.
