[Ken Simpson, W8EK]

TVI filters For Sale:

E F Johnson low pass filter
52 ohms impedance, Catalog number 250-20.  This is the
cylindrical filter, with an SO-239 connector on each end.
There is also a variable cap on each end, for precise adjustment
to cure your particular TVI problem.  $30

B & W 425 "antique" low pass filter
I know most people are not going to think that a B & W 425
low pass filter is that old, but this one is. It appears that the
case is made of copper, or at least copper plated, and then
painted.  There are just enough of the paint flakes coming
off to see the copper underneath.  The weight of this filter
is about twice that of the more modern B & W 425 filters.
In case any one does not know, the 425 is rated to take full
legal power, and cuts off just above 10 meters.  $30.

TVI filter, made by Communications Power, Inc in the USA.
This appears to be a bandpass filter for use on 10 (or 11)
meters, and is rated at 600 watts. It has provisions for tuning
the input and output for maximum TVI reduction. SO-239
connector on each end.  $ 30

Prices do not include shipping from Florida.

Thanks.
