I know this is an old thread i made back in the day but the problem was found with help from nomad was a 22k surface mount resistor hidden under a solder blob on underside of the board that would repeat a 10KHz signal from 25 Mhz to 30Mhz+ getting weaker as it got away from selected freq/channel.
Hi folks been gone a while found this old bookmark thought i would drop by and say howdy. Found this radio on fleabay some thing for your amusement was in the sold list for $2,700 ...A cobra 2000gtl check out the board is it me or this thing missing X3 (11.3258) ,,how the heck would it work lol
With nomad's help I found the issue a smd resistor covered by a bad solder joint on IC5 put in at the factory by mistake and caused the issue.
New look at the output signal after the fix
If any one needs one of these I have some brand new one not old pulls and they ring slightly higher and are easy to trim down to freq with radio's stock trimmers.

This what i found on the mod
Reversed the mod no change still tx and rx on several channels at once
I read that the filter FL3 is so cheap that is why it tx's and rx's so wide. I would like to hear if any one has a saturn turbo or eagle 5000 or 2990 having any issues like hearing next channel over clearly.
I changed out FL1 and FL3 and no change.
I aligned this thing 7 ways to sunday and can not get the spurs out only way is to detune it so bad output is at all most zero.
I used 4 different radio procedures. Unless there is something different on the stock Sm for the radio that i am missing.
