Universal Frequency Counter for Jackson or FT-101/FT-277

I have a Sommerkamp FT-277B and a President Jackson. I tried one time to build a Frequency counter  what shows me the frequency in receiving mode. With the newest firmware you can switch the mode between: Normal, FT-277 Low, FT-277 High and Jackson. The ZF Frequency are in the Firmware, see the Source code.
