Component Descriptions
- Kelemen DP-804020
A 26-meter long trap dipole for 80, 40, and 20 meters, mounted as an inverted-V with my mast as the center support.

- 1708B
MFJ-1708B-SDR — this device allows simultaneous reception with both a transceiver and an SDR receiver. When transmitting, the SDR is automatically disconnected via HF sensing.

-
SpyVerter R2
Since the SDR receiver doesn't go below 24 MHz, the signal must be up-converted to monitor HF. This unit shifts the signal up by 120 MHz and covers a frequency range of 1–60 MHz. It’s powered via bias tee from the SDR.
https://airspy.com/spyverter-r2/ -
Airspy R2
SDR receiver with a 12-bit ADC capable of displaying nearly 10 MHz at once. This model was chosen for its open documentation.
https://airspy.com/airspy-r2/ -
FT-950
An HF rig from Yaesu. It’s an older radio without a waterfall display, but with plenty of knobs and buttons. Manufactured starting in 2007 and now discontinued.
https://www.rigpix.com/yaesu/ft950.htm -
Signalink USB
Audio interface from Tigertronics used to enable computer-based communication. Essential for digital modes like JS8 and FT8.
https://tigertronics.com/ -
Flrig
This software interfaces with the FT-950. All other applications communicate with the transceiver through Flrig.
http://www.w1hkj.com/ -
CAT-Relay
Since both the FT-950 and SDR++ are receivers, they don’t expect to be controlled by another radio. To solve this, N2IV developed CAT-Relay. This setup uses a fork maintained by WG1V.
https://github.com/cdhowe/cat-relay -
SDR++
Used as a panadapter to display the entire amateur radio band at once.
https://www.sdrpp.org/ -
JS8Call eller WSJT-X
Controlled by or controls the radio via Flrig and uses Signalink for audio input/output.
https://js8call.com/
https://wsjt.sourceforge.io/wsjtx.html -
GridTracker
Helps visualize traffic and completed QSOs. GridTracker also handles logging to Cloudlog when using WSJT-X.
https://gridtracker.org/ -
CL CatQt
Work in progress. This is needed to integrate the radio with the logging software that runs on a server and is accessed via a web UI. -
Cloudlog
Work in progress. It’s up and running, but not yet integrated with the radio.
