I didn't know they were so popular Woody.
I got to ask though, how do you get these units you work on to be so stable in your work shop? If I fire up my SD2100 in the yard the thing goes beserk.
debongos:
Tried the Interference filter on the weekend and yes the unit was much smoother. I found myself concentrating solely on the ground balance as there was no warble or other interference even with a 5000 and a SDC 2300 near by.
Woody I normally use your recommended settings for the modified 4500 and manually tuned the unit which on the weekend was around 110 with the filter in use. As an exercise I tried the auto tune as well with the filter and it settled around 210. I was puzzled why there was such a variation as both seemed to provide the same result.

woody:
That is an interesting observation, the frequency setting seems to work with stock standard detectors but with the mods it changes the ratio shown as tuning numbers on the LCD, with the mods it is ok just to autotune it.
Here is a vid of the filter being tested.
