Cost

The receivers with today's tedious hybrid amplifier technology and without including the benefit of quantity savings is $50K per receiver times 64 = $3.2M. MMICs and quantity savings should bring this cost down considerably. $3.2M should be considered a reasonable limit including all other modifications. I don't believe the $10M and greater costs that has been floating around. These are straight forward receivers. For example, 24 similar receivers have been in a small lab at Chicago. Furthermore, the dewar housing the Band 1 receivers may also include the 70-90 GHz HEMT receiver as well as the WVR receivers. If this is the case, then the incremental cost of adding the Band 1 receivers would be MUCH less than $3.2M. I do not believe there is a strong need to have the WVM and the Band 1 receivers working simultaneously. This would presumably simplify the optics.
