Ham Radio

In this video I put up a 20 meter band Delta Sky Loop Antenna with lighting arrestor to use with my HackRF One software defined radio.
I then demonstrate good reception from all over the USA as far away as 1500 miles using SDR Console software version 2 by SDR-Radio
I was able to use CW, AM, FM (narrow & wide) modes on HF and VHF without problems. The software is a bit difficult but I cover some tips in the video that worked for me.
My sky loop antenna was ~128feet long tuned for 1.2:1 SWR at 14.07 MHz
Hoping to use the HackRF for PSK and JT9 at 30 mW TX

This is PART 5 of the project “Arduino Frequency Display For a Kenwood TS-520S HF Ham Radio”.
Steve Leander from www.kv6o.com picked up where I left off in part 4 and completed the project.
He designed a complete DG5 emulator Arduino shield starting from the prototype circuit and adding 5v power regulation and support of a LCD display. Steve completed the software and shared the BOM list, parts purchase links, circuit drawings and his code (here). Thank you Steve for finishing the DG5 emulator board and Arduino code!

Many thanks also to Larry from YouTube Channel “RadioHamGuy” for helping with testing.
Larry makes many great videos about ham and CB radios. Larry shared his side of the contact on video which is posted below my contact video.

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).
