Have any of you folks changed the 8.83 mhz IF filter and the 455 I F filter
in the TS-870S with sharper filters from International Radio or InRad and
what were you results like? Also, what is the web site for InRad as I can't
seem to find it now.
    Another observation is using the SM-220 monitor scope with the TS-870S
is that the display on receive incoming signal is very very low if the AIP
is turned ON on the 870S. I have NOT done any mods to my radio as yet except
to replace the main eprom located in the front panel which has made some
improvement to the DSP especially in the receive mod. Have any of you users
noticed that and do you have a fix for it? I contacted Kenwood service
department in Toronto this morning and they were NOT aware of that problem.
