Very good for the money and no problems at all here.

Post by someYguy » Wed Nov 30, 2016 5:30 am

Hi All,

I've been using the RSP1 for several months now and it works flawlessly here. I'm using HDSDR, SDRUno, SDR#, and SDR console v3. Each program has its advantages but I use HDSDR most of the time because its ultra stable and IMO has the most effective filtering.

Antennas in use are a 130ft. homebrew double-bazooka @ 35ft, and a Doxytronics model 8020ca portable magnetic loop. Both work well with this receiver on HF.

No trouble with center spike, very little with images & birdies. I also use my RSP1 to monitor local public service in the 150-160mhz region, no trouble there either. It is as sensitive & selective as other receivers here (Radio Shack & Uniden scanners).

Computer is a Winbook TW700 7-inch tablet, running Windows 8.1. Using an Acer 17-inch eternal monitor for bigger display as needed.

So how do I get this great performance? Glad you asked :). First, I ditched the RSP1 AGC right away and went to manual control of the Gain Reduction in the SDRPlay Device Controller panel. For me, a setting of 37 results in excellent HF performance with no noticeable overloading. On the MW broadcast band, I set it to 57 and it performs beautifully. I very rarely use the LNA, it is pretty much always off. IF mode is set to Low IF usually unless I need to see more spectrum but this computer will only allow up to about 2mhz anyway which is more than enough for most purposes.

I also have all of the SDR programs which allow it (HDSDR & SDR#) set to automatically compensate for I & Q imbalance.

So all in all, I find this to be a very capable receiver and spectrum analyzer. Learn how to use the gain settings and when to use (or not) the LNA and you won't be disappointed.

I should add that I live within a basin, surrounded by (7) 10-20kw FM broadcast transmitters on top of the local mountains. There are also (4) 1-5kw AMBC transmitters here, with one of them just 2 mi. from me.

With the RSP1 settings which I use as noted in the post above, I do not see any substantial interference nor images from the broadcasters.

Anyway, hope that this helps someone :)

Just to be clear - you're okay with avoiding it, or you don't see a center spike at all?

I ask because I see a center spike all the time and have to avoid it to get a decent signal.

Hi Noel, sorry about late reply but I just now saw this. To answer - I see no center spike at all wiyh HDSDR and sometimes just a tiny one with SDR# but it isn't always present.
