The Instructions

The 19-page manual will get you aligning vintage AM radios moments after you plug in your new FY6900 signal generator. Topics include:

  • A quick look at superheterodyne radio theory and circuitry

  • How to connect your 6900 to a computer to simplify setup and operation

  • How to use the 6900 without your computer, if you like

  • A detailed description of the specific test frequencies and settings needed for alignment and tracking work

  • How to setup and save groups of FY6900 settings to speed up alignment and tracking work

  • Descriptions of the FY6900's quirks, and their work-arounds

  • A step-by-step, illustrated example of a radio alignment

  • Dozens of tips and tricks

  • Suggested DIY accessories that you can make at home

  • And much more

The RF Coupler

This compact coupler contains a ferrite loop antenna and the necessary capacitive isolation to be compatible with the FY6900 and similar devices. The plastic enclosure keeps those components safe. The case measures about 2" Long x 1-1/4" Wide x 5/8" Deep. (55mm x 35mm x 15mm). Depth at the connector extends to about one-inch (25mm).  

Its BNC connector makes it compatible with many contemporary generators besides the FY6900. I also separately sell cables that convert the BNC coupler connection to vintage Amphenol-style connectors used by RF generators such as those from Heathkit, B&K, Eico and others. 

The Alignment Tools

 This handy, non-metallic tool assortment is designed to help you quickly adjust IF coils, oscillator coils and trimming capacitors. They won't detune things as you work and fit many common transistor and tube radio coils and trimmers. 

The FY6900 Generator

Know worldwide for being an amazing value, this two-channel generator can provide you all of the RF and audio signals that you need for alignment and tracking work. It comes with a variety of useful BNC cables as well, including some with clips. When used with the instruction booklet that you won't find anywhere else, you'll be a whizz in no time, even if you have never aligned a radio before.
