Hi ,
the intention never to go against copyright, bad would be more important that there was more information for fundamental data recovery of HDD and perhaps a fixed topic with relevant information to repair this model of unit.

Re: [Problems with 3 Aeroflex 2975]
Hi
I recovered some logic boards of this model and some had faults in the Vcore voltage electrolytic capacitors and others in the PWM oscillator of the processor voltages plus what is very common in this unit really are HDD failures.

first make sure that you have a bootable 2975, then with the help of a PC and the DDrescue software try to recover the errors from the HDD using this software

Hi JC ,
In these units 2975 there are important points to check, first check the Bios Battery, according to whether the RTC unit is perfect and a very important detail and check if the HDD has no damaged sector to do so use the DDrescue of LInux

Re: "Portable" spectrum analyzer for filter work?
The resolution for a portable device has its limitations, for determining types of adjustment I still prefer the line Hp and IFR, but that is a particular opposition and correct if you can get some for testing,
