[1000mp] SUB RECEIVER FILTER WANTED

[David & Elly McAulay]

Hi all
Wonder if someone might suggest a filter to buy for the sub receiver in my
1000mp (not mark5)

Should i be looking for a YF-115c filter.?
and if so can someone share with me if its really worth the time and money.

As at present the lack of filter in the sub receiver leaves it as wide as a
barn door


All replies appreciated

either directly to me or on the MP list


Thank you
