Microwave Advances

Providing Legacy Telecommunicaton Equipment Support and Solutions

SERVICES

We offer over 30 years of experience in the telecommunications radio repair and design fields, including microwave component design for those radios that need parts no longer available. We are more than a repair and maintenance company; we have been able to develop and design solutions for equipment that would have otherwise been deemed unrepairable or obsolete. An example of this is the design of the 23 Ghz Stability Rebuild,which provided an answer for both quality and relocation issues for existing MRC and MA-COM 23 GHz radios and filled the need for continued use of working radios while dealing with newer FCC guidelines.

LEGACY REPAIRS

Our ability to think outside of the box when dealing with difficult repairs means that we are able to provide repairs for many radios and components that would otherwise be deemed unrepairable.

YIG REPAIRS

Are you having problems with failures of your MRC YIG oscillators? We have repaired hundreds of MRC YIGs as well as other types of oscillators and related equipment, up to 23GHz.

A WORD ABOUT PACKING AND SHIPPING

 

Many of the microwave radios that we repair, such as the MRC Twinstream and DAR radios, are large rackmounted units and are heavy. As precision radio equipment, they are also delicate.

    • Larger items like these should, ideally, be packed in foam pieces, cut to exactly fit the radio into the shipping box.
    • The box should have at least 2 inches of space all around the unit (all 4 sides plus top and bottom) to allow for impacts that will occur in shipment. If foam blocks are not available, then bubble wrap is acceptable if a lot of it is wrapped closely around and around the unit, going both ways, to a thickness of at least 2 inches on all sides, top, and bottom.
    • Tape it all up securely.
    • Pay special attention to protrusions, such as rack mounting ears and handles; these are often where the damage occurs.
    • The packing should NEVER be loose, and enough must be used to create an exact fit into the shipping box.
    • In many cases, and particularly with the MRC radios, there is a card cage section with removable modules; here you may want to open the front panel and insert a small folded piece of bubble wrap against the card-ends, so that it just fills the space between the cards and the inside of the front panel when it is reclosed. This will prevent the cards from sliding out in the event of shipping impacts.
    • Shipping boxes for all heavier items should be heavy wall or double wall cardboard; do not use the thinner “economy” boxes offered by many packaging sellers.
    • If you still have the original manufacturer’s packaging from the units, then use that, so long as it is still in good shape. Most of them used pre-cut and shaped foam inserts to fit the equipment.
    • NEVER pack more than one rack mount size radio in a single box. We know it is an attractive way to reduce shipping costs, but we have seen much shipping damage occur with these large and heavy packages. You will not save any money if the repair ends up being more expensive due to damage!
We have been shipping and receiving packages here for many years, and you can trust that there often will be rough handling by shippers. These precautions will go a long way to minimize problems. Thank you!
