Bought this for alignment of old radios, I rate this at 5 stars as I've only used it once since purchase earlier this year and it worked fine so the radio I aligned with it performs better now.The key I.F. (Intermediate Frequencies) are clearly marked on the dial scale by arrows so finding the right frequency is more precise. The audio modulation works well also. I don't have a frequency counter so I can't comment on the accuracy of the unit but looks to be plenty precise for the AM/shortwave radios I tinker with.I've been a customer of MCM since the mid 1990's when everyone seemed to ask me to fix their VCR (remember those?) and MCM is where I got all of my VCR belt and tire kits/parts back then.I recommend this product.
I have several other signal generators so far this looks like it will be my favorite for some time to come . Just the right size and easy to operate.
