Greetings all,
After five years and a few months of hectic but rewarding work, I again find
myself seeking new employment.
Fortunately for anyone who is seeking a senior level Regulatory Engineer or
Regulatory Team Leader, I have some great qualifications. For the last five
years, I've
Can someone provide a thumbnail sketch on the process of importing a
wireless communication headset (such as those used at McDonald's et al)?
Are EMC/radio test reports from accredited test houses outside of Russia
accepted? Are markings required?
Thank you,

I have a need to do DO-160/ED14 RS testing of a system with fairly large
component EUT's. It seemed to me that the best way to do this is in a
mode-tuned chamber, but there seems a paucity of such in the field, and
those I've found so far seem too small for the system I wish to test. Have

The question has come up whether there are any requirements on the gold
plating thickness for Ethernet Connectors (not used for telco interface),
similar to the requirements for 50u of Gold for Telco connections.
I have not found any yet. However, I am going to check with the safety agency

Thanks guys, but the question was not where can I get copies of these
standards?, but a request for a technical comparison of the limits / levels /
methods embodied within them.
Which as you can appreciate, is no small task. So not wishing to possibly
re-invent the wheel, I posed the question

Dear Members,

I have had a fair amount of experience in making sure that military systems
can meet the MIL-STD-461 RS103 requirement of 200 V/M. However, we are now
seeing system requirements for levels from MIL-STD-464 (and other places).
These new requirements invoke immunity to levels such as 8 GHz to 10 GHz
I see very little response at those frequencies and levels. Recall that
coupling efficiency to circuits decreases with increasing frequency. 21,000
V/m at 10 GHz couples the same level as 2100 V/m at 1 GHz, which is like 210
V/m at 100 MHz. But then you need to look at modulation. Usually these
