Just discovered my MARTI BR-10 receiver broadcasts but sounds like the ocean during
a hurricane.  Anyone out there in the atmosphere have a backup I can rent while I am
sending the sick one to the radio hospital?
Frequencies are 153.11 or 153.17. 
I would truly appreciate any help at all.
Thank you in advance.

Good Luck...those aren't FCC authorized Marti Freqs...unless there's a band I'm not familiar with. You can use a programmble scanner to receive a Marti signal in a pinch.

Actually, they are authorized frequencies.  The FCC issued Marti frequencies in the 150 range for some reason, don't remember why at the moment.  I worked at a station in Richmond, KY that had a Marti set for a 153 frequency. 

As far as a make shift receiver, Bob's suggestion of using a scanner will work in a pinch.  The audio fidelity will be  less due to the narrow bandwidth of the scanner, but it will work.

Thanks for the scanner suggestion, I hadn't thought about that.  Marti used those frequencies to reduce interference from consumer equipment decades ago.

Who says you don't learn anything of use on these boards? Thanks for enlightening me...

Hey Spindoctor...

I'll just be real professional here and conduct internal office communication via Radio-Info Smiley I forgot about being able to use a scanner...there's a brand new one floating around the office somewhere...I bought it about two years ago and never used it since it can't pick up aviation frequencies. And, as is the case with just about everything I've ever bought, the box is also there, too, along with the original receipt, and an AC adapter. Libby probably knows where it is...and it sounds pretty good, too.

Thanks, guys for reminding us of such a simple solution!
