Jay, All TR-4s and all T-4Xs shift the CW carrier, and its very close to 1KHz.? If you want to be on the other stations frequency, you need to tune his note to 1KHz. ? This offset is done by a switched in capacitor so it is not precisely 1KHz, if you have another receiver you could listen and determine what it really is on your rig. (or use a frequency counter) ? 1KHz is pretty high, normally you would like it lower like Steve.? The TR-4CW-RIT solves that problem.? So does operating the 4-line separates by operating in separate mode. ? 73, Gary WB6OGD ?
