One thing that wasn't mentioned about the SRF-T615 receiver is its sometimes useful noise reduction feature. I normally don't switch it one, but on occasion have found it useful.
I'm lucky enough to have two T615's and use one most of the time. One is set to 10 kHz steps and the other to 9 kHz. As I live in Oklahoma, I may have to travel to Newfoundland use the 9 kHz steps. But I continue to hope.
While I don't know the exact battery life, the T615 give a good amount of DX on two AAA batteries.
