[1000mp] Roofing Filters

[Roger Cooke]

Hi Mike.

  Let me know where the best place to obtain a roofing filter in the
USA please.
It will be cheaper than buying in rip-off UK ltd.

Hi Pete

I think my posting was taken in the wrong context. After things settle
down
from the Holidays, or if it's possible, I will probably be ordering my
roofing filter as soon as next week. I have the cw filters already in
the
rig.

Here's the statement that I guess bothered me:

<snip from below>
Several of my contest club friends have
>>told me that the "roofing filter" is a must in this rig for
contesting????

I was just trying to point out that the 1000 MP series has been among
the
best contest rigs available long before the roofing filter mod came
out.
That is the beginning and end of what I was trying to state. And, the
considerate MP owner has his radio "de-clicked" (mine has).

I realize the roofing filter mod is quite an improvement, and will be
ordering mine as soon as I can.

73, Happy Holidays Mike K9MI
