===== Description =====
(From a review posted by K0BRA on the [[http://www.amrad.org/|AMRAD]] Tacos mailing list.)

The RX321 was based on the RX320 and was built to specifications for Globe Wireless for a shipboard project.  Globe Wireless abandoned the project and new units were sold off.

The RX321 is slightly larger and more robust than the RX320 to accommodate a larger RF front end board that is different than the 
RX-320 RF front end.  It includes a mounting bracket that would facilitate mounting on a bulkhead or table.

The intermod specs are improved.  The RX320 is spec'd at 3rd order at +10 dBm while the RX321 is spec'd at +15 dBm.  The second order 
intercept of the RX321 is spec'd at +60 dBM while the RX320 is not specified.

The oscillators are oversized in the RX321 and are spec'd at +/- 10 Hz over 0 to 40 degrees C.

The active antenna included inside the RX320 is gone with the RX321.

The antenna connector is an SO-239 on the RX321 instead of the RCA plug on the RX320.

The DC power is shown as 12 - 24 VDC on the RX321 instead of the unspecified power on the RX320 using a wall-wart.  The RX321 includes a power distribution board that was added most likely to clean up dirty ships power.

DC power and the speaker connect via a terminal strip on the RX321.  The RX320 uses phone plugs and DC coaxial connectors.

Remote audio line out on the RX321 is a balanced, center tapped transformer.

The RX321 comes with a 120 VAC to 12 VDC switching power supply.  The RX321 has a power LED and a more rugged power switch.

The RX321 will operate with RX320 software.  The DSP board is slightly different with a different part number and different EPROM identifier.
