Earlier tonight, I noticed that CW traffic on 40m picked way up. You get an interesting view of the band conditions when you can tune 100Khz at a time:

Even with my own wimpy antenna, it was hopping pretty good.

Hi Mark,

That SDR-IQ seems to be a pretty fantastic piece of gear. How have you connected it for use on the air? I’ve heard it interfaces with the ft-950 and a couple other rigs form their special direct IF output port; but I don’t think your ft-817 does that!

It’s an amazing piece of hardware. When coupled with software (SDR). it opens a new word of receiving signals.

I am curious to know how this device handles TX interference from your transceiver….how does it suppresses this interference.
