Bill Harms has some nice fine tuning set up on his phaser. Bill says it

Yes indeed that was his famous loop. Just think if Gordon was around
today with phasing units.

I can't take credit for the original idea. That came from Jerry E.
on #mwdx. He made the suggestion to on the chat room. I just took
it from there.

Bob,
In the early days, using a loop to null with was fine except sometimes
you are left with a signal that is not very useable. I find with phasers
since you are using outdoor antennas bring in my signal, during a phase
you generally have more signal left over that is useable. You are not

Bob,
No circuit. It is the retro-fitting of a Vernier Reduction Drive. I
had to make a couple of modifications to make it work. I had to make
a bracket for each pot so the pot will tune properly. The other
modification is the filing of the shaft in a D shape to make the
set screw stay put.

Adding a vernier should be pretty easy. I might do the same too, although

900 is a local station just a km or so across the water from my place. I never
expected to be able to do anything with this signal which is normally S9+60.
Well, with the phaser very carefully adjusted, I knocked the primary Village
900 signal down to less than S9, and underneath can hear a

Walt,
The best investment I made for DXing since I bought my FRG7 many
many years ago was to buy a phaser. I waited until a couple years
ago and I wish I would have done it sooner. With it, I have been
able to log stations under my locals many of which are less than 10
miles away.
