1. 70 Mhz IF filter

KA9UVY has told me about a filter that you can put inline with the
output of a ATV receiver converter that have a TV channel 3 output.
That is channel 4 for the 70 Mhz. filter . You mite have to retune the
converter a little. Its LO frequency needs to be 509.25Mhz for 439.25
Mhz Rx. We have be using this filter for a couple months now and for
weak signal Rx its the best.
Here is what it can do for you. It will take a P0 Just sync showing
on the screen to a P2 readable screen. The transmitting station will
have to use Big Call LETTERS on there Tx video but it will improve the
Rx video. The only drawback is if you put the filter on 300Khz it
does reduce the sharpness of the video but at P2 what does it matter ?
Here is three links to the filter they are only $28.00
and it has a $12 shipping charge.
