<div>Sean, the power source is the battery from the trolling motor. Plus the trolling motor may have been running drawing it down. I call it a radio for convenience. ;-) I used to use two batteries, and will experiment a bit.</div><div><br></div><div>Hank</div><div><br></div>

<div>Sean, now that mention that, I have a battery powering the electric motor connected to the radio with a power converted that converts 12v to 24 v. I just asked my wife if they were motoring while talking and they may have been. That means there could have been a voltage drop to the radio. Could that be the culprit? </div><div>Hank</div><div><br clear="none"></div>

<div>Sean, on 27 kHz the radio is crystal clear but at 225 feet, the surface radio can hear me clearly but in she sub it was very clear but super quiet. I am assuming that I need to get onto the 10khz side for range. Unfortunately Gamma came with the wrong paperwork for the come. I ended up with Delta's paperwork and the radios are different. The link you sent shows a very similar radio and it says 3km for the 27 kHz side, so this makes me wonder if I have a simple problem with my 27 kHz side. </div><div>I have no clue if it is strait frequency. I can look in my paperwork to see if there is anything at all.</div><div>Mine has a pinger also</div><div>Hank</div><div><br clear="none"></div>

Human hearing covers 20 Hz - 20 kHz. 9 kHz would be audible, not ultrasonic.
