Re: Low Audio on AO-27?



Tried correcting for Doppler to no avail, the signal has been like that for
several weeks. At sometimes, it was barely out of the noise floor on a high
elevation pass, yet UO-14 was coming in like gang busters ( I can aim my
Arrow  at the ground and hear it). Lead me to comment that I thought it was
on its  way out.
