[TenTec] notch filter for Eagle?

[Greg S]

Every ICOM HF rig has a manual and auto notch. Unfortunately most are an either/or proposition.

 You guys are all out in right
 field.
 
 No radio's auto
 notch filter works in CW mode.
 They cannot
 distinguish between the useful tone and the disturbing
 tone.
 
 And yes, in that
 case, a manual notch filter is indeed better, but show me
 a
 radio built today that has one.
 
 I find the Eagle's notch
 filter effective on SSB.

 I _LOVE_ my Orion II notch
 filter!  
 
 The automatic
 feature is good, but the manual one is about the best
 I've
 ever used.

 A//B VFO, there really is no A or B VFO in the
 traditional sense and Eagle only has one tuning
 knob. Therefore, the A/B
 indicator serves no
 function in transceive operation. In split operation,
 that indicator should flip when going fro RX to
 TX to tell you which
 displayed frequency is
 the TX frequency.
