Looking pretty good here

Postby kc6ete » Thu May 04, 2017 8:51 pm

I just got mine last week, and I've been using it a bit.
It tunes broadcast AM and FM reasonably well.

My only real issue so far, is some annoying spurs that crop up from time to time but I'm probably doing something wrong.
At some point, I will take it into the lab and check sensitivity etc against our equipment.
I haven't taken it outside to play on HF yet, but that's in the plans as well.

So far I'm impressed.

The hardware and Uno software are indeed very good, but like all SDR's that boast a wide spectrum display, they will show images and other spurii. Narrow front-end filtering will get rid of the unwanted responses, but of course this will stop you using the much-trumpeted 10 MHz b/w. I find the SDR2 and SDRUno combination to be a close match with my other RX's, including a Trio R1000 and a Winradio 305.
The thing to watch for is overloading caused by too much gain. It's always worth checking that Uno has selected a sensible RF gain when switching bands or antennas - it seems a bit buggy in this area.

I know about birdies, and I think I have reasonable expectations. Even my IC-R8500 has a few birdies.

I'm still learning to drive this thing, and always looking to improve.
