I have to go with Robb on this. I too have done this mod on several different radios and always have had noticable results. If you are absolutely sure that all the components were installed correctly, then it might be possible that something else is going on with the receiver. It is also not a good comparison to use the S-meter from a different radio to campare signals. Your Sears Roadtalker could be adjusted completely differently from the factory than say your DX-959. Also, your radio should not require a re-alignment since you are not replacing or upgrading any components that would effect the frequency.

When I did my DX-949 (which was the first radio I performed the mod on), I wrote down the S-meter readings of operators that regularly talked to that were at some distance from me. I also took note of the noise level as well as the effect that the NB had on the noise level and S-meter reading of the noise floor. After the mod, I saw a 1/2 to 1 S-unit increase in signal and a drop of about 1/2 to 1 S-unit in noise. The NB was in part responsible for that noise drop. I also had the opportunity to compare my modded DX-949 to my friends stock DX-2547 (same circuit board) side by side through a coax switch and there is a definite benefit to performing the mod. Most noticeable is that there is considerably less noise on the received signals.

[QUOTE="Ronin, post: 274600, member: 2545"] I have to go with Robb on this. I too have done this mod on several different radios and always have had noticable results.

It is also not a good comparison to use the S-meter from a different radio to campare signals. Your Sears Roadtalker could be adjusted completely differently from the factory than say your DX-959.
