The '3 series of mixer from MCL are good down to about 25kHz. Good
performance can be expected another octave down from there. Does the
synthesizer in your WJ receiver provide +17dBm of LO injection? The mixer
you ordered is a Level 17 mixer. The MCL website does have the pinout for
this device. I like the '3 series, since the SSB conversion loss is in the
4.75dB range vs other series, which have conversion loss in the 6.5dB range.
This is a very good mixer. Now, which mixer is your WJ receiver using? Some
of the WJ units used a mixer that had a pinout similar to MCL's GRA-3.

If you don't have their catalogs lying around, there are two more
possibilities... Do a google to find their website and they may have
everything on online. Otherwise, call their customer service line and

tell them the info you need.... In my previous life, they gave
excellent
support...

Good luck,
