KX155A/KX165A with lower GPS interference in the RF output?
Peter - 2009-04-16 08:05:00
Hi All,
I have a case of that well known interference on the 13th harmonic of
121.15 121.175 121.20 messing up GPS.
The standard TED filters don't do much, probably because I cannot fit
them precisely on the back of the radios but there is a ~ 2ft length
of coax cable which is inaccessible ...

Hi all,
I'm looking for some sort of frequency standard (10 MHz ref.?).
Ebay has rubdium frequency standards for under $100.00
and there are also GPS disciplined OXCO frequency standards for
