Icom 7300 Panadapter With DXPatrol, Mini Circuits Splitter And HDSDR
UPDATE: THERE IS A MINI CIRCUITS ZSC-2-2+ AVAILABLE ESPECIALLY FOR AMATEUR RADIO. SEE HERE.
HDSDR displays the 7300's scope on an external monitor (not technically correct, but sufficient). We get better resolution and a larger picture of the spectrum scope. It's possible to see an entire band or more and we can tune the 7300 with our panadapter. Use the mouse, point and click on the desired signal in HDSDR and the radio follows. Any changes done to the VFO, band and mode made by HDSDR are tracked by the 7300 and vice versa.
With a panadapter I can see an entire band on my screen and jump from station to station ( See this short clip). This will work extremely well in a contest or even Field Day if you were searching and pouncing. It's also just nice to have in normal operating.
Total cost for this is around $200. The DXPatrol was $108 and can be used for other things as well. You could try a RTL-SDR for $25 and it may work for you. You could also try a simple RCA "Y" cable splitter in place of the Mini Circuits splitter/combiner. I tried one, but it had too much noise and interference. See my list at the end of this article.
Icom 7300 Panadapter Installation Instructions
- Install the Inrad RX7300. See my previous post.
- Attach the cables and Mini Circuits splitter/combiner. Attach the left ( looking from the rear) RCA to the "S" SMA connector on the Mini Circuits splitter. Connect the right RCA to the "1" SMA connector on the Mini Circuits and finally, connect the SDR you have to the "2" SMA connector on the Mini Circuits. (Other configurations are possible.)
