THE FAMOUS "YELLOW CARD"

Our company is constantly evolving and growing. We can send you a yellow card either through US Mail, or electronically. We provide wide range of services for reading carrier frequencies for broadcast Radio and Television stations. We also do NRSC-2 measurements for AM broadcast stations. Our mission is to provide best, most accurate service possible. Radio Aids is almost 70 years old and some of our clients have been customers for the entire time we have been in business.
That helps everyone. If you want to contact us, please fill the contact form on our website. We wish you a good day! You will find that the yellow card will be very valuable during stressful FCC inspection.
In general, most modern transmitters out by themselves in a cornfield should pass the emission and harmonic tests with excellence. Substantial variances between measurement sets, however, may be indicative of subtle problems with the rig that may not be overtly noticeable by power levels and the like. Splatter above the mask levels may result from issues in the final amplifier stage, while unexplainable spurs from a lone transmitter may indicate PDM problems. NRSC measurements keep neighbors happy and provide an additional check on your facility's performance.
A colleague and friend of mine has quipped that NRSC measurements are the “annual albatross” due to the resources spent on their acquisition. Too often, the holders of the purse strings also view the measurements as a fatuous exercise. Like any coin, there are always two sides, and the NRSC measurements are another beneficial tool in the box.
Regardless of your view of them, they must be performed no less frequently than once every 14 months and are one of the things the commission looks for when paying a visit. Since the requirements have been around for two decades, it is a challenge to have to explain to the inspector why they are absent from your files.
Do not be that guy.
