The resistors could be replaced with two presets to balance out the carrier
due to differences between the individual diodes.

Subject: [minima] Modified Diode Mixer
Hi all,
I came across a modified diode mixer in an old Technical Topics in Radcom
(May 05), designed by G3UUR. It looks easier to build than the mixer in
the Minima 3 schematic, since it uses bifilar rather than trifilar
windings. I haven't built it, but would be interested to hear if it has
any disadvantages. I've attached it, and put it on my site, psk-31.com
