Just a short update video letting my YouTube subscribers and Blog followers know why I haven’t been posting content for about the past 1/2 year. My next post will be a video update on the Kenwood TS-520S HF Ham Radio Arduino Frequency Counter PART 5. So you can look forward to that shortly. As always – “Thanks for joining, subscribing, following and thumbs up ratings.

In the video I mention I will post an inventory list of my vacuum tube collection so if a viewer needs one they can submit a request. I don’t have the list ready but when I do I will post a link to a PDF below and try to keep the file updated.
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
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.
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.
