Has anyone experience to improve the output of Heathkit HD-1250 grid dip meter?
I've had very little luck trying to use my HD-1250 dipper. (Technically, it is a gate dipper, since it uses a FET) I did have some hygain traps from a AV-14 that dipped nicely, but my Cushcraft A3S traps would not dip at all.
I think the HD-1250 needs tighter coupling to get a good dip than some older tube-type dip meters.
It looks to be very difficult to use it when tuning the shunt fet tower.
For my 80m shut feed on a 15m tower, I used an MFJ-259. Much easier than trying to use a dip meter.
