That looks like it would be a very easy modification since the Attn switch is already set up to provide 13.5 V to turn on a relay, and the roofing filter control circuit requires a "high" to turn on
Hi, Ken Regarding placement of selectivity, your suggestion of replacing Y2 is intriguing, although one would have to be very careful of the low end rolloff in this filter. (George at INRAD has alrea

This should be of interest to Omni VI and VI+ users who are planning to use the INRAD roofing filter mod. Dave Bowker, K1FK, has a nice set of instructions for turning the roofing filter on/off using
A couple of days ago, Steve, N4LQ, described a modification to the Omni VI noise blanker to allow it to be more completely turned off when the NB control is turned fully CCW. He changed the values of

Several people have asked me about this topic, so I thought I should share my experience on the reflectors. Keep in mind I operate CW almost exclusively. I now have the "low pitch" CW roofing filter
For several weeks now, I've noticed a pronounced reduction in gain of my Omni 6 after it has been on for a while. When I first turn on the rig, I get an s meter reading of s-2 to s-3 on antenna noise

Someone on this reflector expressed an interest in a 40m vertical dipole. I recently acquired the Force 12 Sigma 40XK "manual band change" vertical dipole which covers 40 thru 10 meters. It's cheaper
