I took my kids to the meteor crater in Arizona USA on May 3rd 2014. I though it would be fun to share a few minutes of the HD footage I took of the meteor crater. The wind noise was very bad, sorry. If you can’t visit Meteorcrater in AZ someday then please enjoy my little tour of the crater. More details about the impact at Meteorcrater.

This is PART 4a (there is a part 4b below) of the project “Arduino Frequency Display For a Kenwood TS-520S HF Ham Radio”. This part covers switching to a new front end circuit as seen used by the DFD2 frequency counter from “Almost All Digital Electronics”. Their website is http://aade.com/DFD2inst/DFD2inst.htm

(PART 4A)

This is PART 4b of the project “Arduino Frequency Display For a Kenwood TS-520S HF Ham Radio”. This part covers testing the circuit and frequency counter software when connected to the Kenwood radio but still on a bread board. The final display is not ready so in this video I simply push the frequence counts to the laptop.

(PART 4B)

Here is the datasheet for the PLL chip I used in (PART 4). Other datasheets can be found in (PART 1).

I liked it quite a lot. I will report back here if my option changes for any reason.
