Also, how far off in frequency was the RX340 in normal operation vs with the

This is not so much of an issue as it may be if you are using several receivers perhaps in space or polarization diversity or plan to use a transmitter or transceiver along with the RX340. In that case you may want to run all of them off the same reference so their frequency settings
will agree.

Indeed.  I actually bought *two* of the standards; the second one will be
used at a site with two 60 foot dishes at it as a reference for the LNB
up at the focal point *and* the receiver down below.  Having the LOs drift
independently would cause false Doppler readings to show up.
