description Heathkit IG-102 Overview
The Heathkit IG-102 is a radio-frequency signal-generator kit from the Heath Company. It produces adjustable RF signals for tasks such as aligning and troubleshooting AM and FM receivers, and it was intended for electronics hobbyists and service technicians. As a kit, it required the builder to assemble and wire the instrument before use, so surviving examples are also relevant to Heathkit collectors and restorers.
help Heathkit IG-102 FAQ
What is the Heathkit IG-102 used for?
The IG-102 is an RF signal generator for injecting known radio-frequency signals into receiver circuits. Hobbyists used it to troubleshoot and align AM and FM radios.
Can the Heathkit IG-102 service FM radios as well as AM radios?
Yes. The IG-102 was designed for receiver servicing across both AM and FM work, including FM alignment procedures described in its assembly manual.
Was the Heathkit IG-102 sold as a finished instrument or a kit?
It was sold as a Heathkit construction project that the owner assembled and wired. A surviving IG-102 can therefore differ significantly in condition depending on the builder's workmanship and later repairs.
Can I connect an IG-102 directly to a vintage radio?
Usually the generator is coupled to the radio's test point or antenna input rather than connected indiscriminately to the chassis. Because the IG-102 is vintage mains-powered equipment, isolation, grounding, and the radio's service manual matter before applying a signal.
