Check the filter very carefully for cold solder joints / loose connections. I
had this problem once with a 500Hz filter and a quick resolder with a 25 watt
iron fixed it.

Subject: Re: [TenTec] OMNI V 500 hz. filter
I have 4 filters in the 6.3 Mhz. IF: 2.4, 1.8, .5, .25. They all work,
but the 500 hz. has less output than the 250 hz. - even when I adjust
the PBT and the FADE/BP controls for max gain. Gain is probably 25% or
so less, but definitely noticeable. Could one of the crystals in the
filter have drifted? Or be bad? I have tried "exercising" the
connections by plugging and unplugging the filter per Don Prouty in the
Ten-Tec service dept. Is this a fixable problem by sending back to
Ten-Tec? Since their hourly rate is $60, maybe just as well to buy a
used one for $60-70 including shipping. Anyone have any ideas?
Thanks, Donald K6RV
