Re: Sound of CW during practice vs. live using QCX+

Jim, wall warts can be very noisy. I have had good results using a wall wart from Meanwell. You might look in to their 15 V product. I get 6 watts on my 20 and 40 QCX plus.

Thanks to everyone who commented on this issue. First, I did transmit into a dummy load and got the same result. But I just figured out what's going on. I recently ordered a rechargeable LiFePO battery which provides 9V and 12V output that just arrived today. I disconnected my 12V wall charger from the QCX+ and hooked up the battery, and low and behold, normal sidetone when I started transmitting!! Not sure exactly what was happening, but the battery clearly made a huge difference. Perhaps Hans may have some ideas about what's going on, but at this point I think I'll just stick to using the external battery.
Thanks to everyone for the quick responses, hopefully my experience may help others.
