Inrad Roofing Filter For Yaesu FT-920

I just recently found out that draft install instructions for the FT-920 Inrad roofing filter have been posted into the files section of the ft920 yahoo group.

The INRAD price list shows the roofing filter priced at $200.00. I’m interested in hearing feedback on how well that mod works with the 920. The filter board was supposed to be a great improvement. I have until now been muddling along without the narrower filters or the filter board mod available from Inrad.

I think the roofing filter may be the answer I was seeking for that radio as a contest rig. I just hope it doesn’t completely ruin the AM reception for SWL’ing. But I have several nearby stations that can sometimes really wipe me out during a contest. All of them combined with the 50KW of WPTF only a mile away really make contesting with simple wire antennas a challenge.

A first glance at the instructions gives me the impression that the install will be simpler than the install for the SSB or CW filter board. That too would be a good thing. I’m not troubled by the soldering involved, but the mechanical dis-assembly is very frustrating.

So for now, the roofing filter is on the wish list. Way Cool.

    I did the Inrad roofing filter mod. Best thing ever for this radio. Leaves about a 5 khz wide signal for am. Suits me.

    No longer have folter blow by like before, now a super receiver.

    I installed the stock filters for the 920 and it did make a lot of difference. Then I installed the Inrad roofing filter. It was like a new radio I could not believe the difference. Every time I go on the air I am just amazed and if you install this filter you to will be amazed.
