# Electronic Product EMC and Regulatory Compliance Consultant > EMC Consulting ## Pages - [Mirage B-5030-G](https://www.trc.guru/miscellaneous/mirage-b-5030-g/): The link to the article I wrote for the Midwest VHF and UHF Society newsletter on how I repaired a Mirage B-5030-G 144-148 MHz Power Amplifier is available on the link below. I bought a Mirage B-5030-G used a couple years ago and when I put it in it had an Input SWR of 1.8 to 1, which was at the top end of its specs. About January of 2025, the SWR jumped to 3 to 1 and the amp became unusable. To fix it I started looking for a schematic but could not find one. After opening it up I […] - [Coax Specifications](https://www.trc.guru/miscellaneous/coax-specifications/): Coax Cable Specification Spreadsheet for Ham Radio I never found a spreadsheet that had all the info I wanted to have for selecting what coax to use for a specific application. So I have now created one with the details of interest to me. If you think I need to add additional info let me know. This is a work in process draft and likely contains errors, so use at your own risk. Keep in mind specs from different manufacturers for the same coax type may have minor differences. In some cases a manufacturer might have multiple versions of the same […] - [Cookie Policy (EU)](https://www.trc.guru/cookie-policy-eu/) - [Circuit Board Planes](https://www.trc.guru/emc-what-now/circuit-board-planes/): In the image below is how I envision a plane in a circuit board. The important part is understanding current follow, which causes unwanted differences in voltages. The primary flow is between two points. When looking at the matrix, where did you place your power connector that provide the current your device (motor in this case) needs? Which op amp will provide the most accurate motor current? What happens if the motor/device is tied to point A and the power connector is at Point C? You can use capacitors to help control surges, but there will still be a DC current […] - [Terms and Conditions](https://www.trc.guru/terms-and-conditions/) - [Privacy Policy](https://www.trc.guru/privacy-policy-2/): Who we are JBRC Consulting LLC, and our website address is: https://www.trc.guru The website: https://the-regulatory-compliance.guru forwards to https://www.trc.guru What personal data we collect and why we collect it Comments We do not allow visitors to create accounts or leave comments / blogs on this website.

If you are going to try and fix the EMC Failure yourself, you might be lucky and the one of the items in the “Easy Items” list might fix your immediate issues. Most likely the lab already tried them.

I crossed paths with my first EMC susceptibility issue about 1973-1974 at the company I worked for. In 1976 area I ran into a RFI issue when my home built CRT terminal started displaying a full screen of capital H’s on the near by 1962 RCA color TV. The H’s overpowered the local TV station. In 1976, when working for a contract manufacturer, we  had a customer come to us with a product that had a failed UL safety certification.
