methinks thou bs 's too much,
in another post you said "No mods. Stock cobra 2000 ..."
since when is channel 39, 26.915 Mhz?
They'll never find the amp section of my 2000 I hid it...
too many watts with too many close neighbors. i had same issue in trailer park
antenna is using your coax as rest of antenna . just like the a99 does .
then add to mix running 30 watt dk with 100 pep.
reciepe for disaster. try making a rf choke 8 inches diameter by 8 turns
and maybe make radials longer [think i seen this already] it may help
better advice is put a 300 watt system in your mobile and go find a hill
and talk dx that way just my 2 cents
