I have a 500 mhz frequency counter I bought from Fletcher Electronics,, It works great but i cannot get it to read exactly, the frequency readings in the photo should read 146.520 and 446.125
I bought it to install in my MFJ 9406, but sold the radio already here on Ham Shack
as you can see, Fletcher sold me a defective counter, and I will sell it for less than I paid that it sort of works but does not read accurately
You can have it a try As Is for just $10 plus postage
