Simon Brown
 

Yes,

 

I did when I first received it and added support. From memory the HF+ has better MDS & Dynamic Range, I could bring it into the radio room/office but it’s usually in use remotely by a colleague in the US.

Simon,

 

Have you had a chance check out the VHF reception on the Elad FDM-S2?

I have everything 😊 . I’ll get the log periodic onto the rotator and then do some proper tests.
Playing with 2m and Marine 156MHz produces quite amazing results, the radio is unbelievably sensitive yet doesn’t overload.

Hello:

Using last 32 bits SDR#.

Why can't i change samplerate?
Always fixed to 48000.

Thank's a lot.

I don't know about the HF+, but the AirSpy is completely capable of displaying the entire FM BCB.  Use SpectrumSpy.  Not only that, but it can show per a spectrum analyzer sytle display, the full range of the AirSpy, roughly 25 MHz through 1.8 GHz.  All this without dropping at the band edges.

Re: HF+ WX Reception

I would rather put the wide band FM stuff in the "specialty" category. Especially that all the existing wide band receivers lack the dynamic range and filtering required to decode the weak signals "they see". That's exactly the problem the "+" of the HF+ is solving.

Thanks for that Simon.  Much better than the Funcube Dongle Pro+, indeed... which is practically unusable on LF without the
use of a good LP filter.

Re: HF+ WX Reception

Edited

The other "novelty" is that the gain distribution is fully managed by the different AGC loops. Also, the effect of the AGC in the RF/IF stages is compensated with digital gain to avoid clicks and noise floor bouncing. It's quite pleasurable to operate.
The absolute dB reading may not be what one would expect, but the SNR is always optimal for the situation - Isn't that what matters the most?


Re: HF+ WX Reception

Marcus D. Leech <mleech@...>
 

I've always felt that the inexperienced shouldn't be allowed to look at the FFT display of a quite-sensitive receiver.  Because that will produce a barrage of "OMG, what's *THAT*?" type questions.  You know the drill, 30Hz-wide spurs that are only 5dB above the noise floor and people getting into a panic about them.....

Note that the MDS is about 5 dB lower in the HF+, so more externally generated spurs will be unburied.

And here’s a similar shot using the NetSDR with extra good TXCO, same antenna as HF+.

Hello Simon,

   have you had the chance to do a similar test also on LF/VLF ? When tuned to below 100 kHz, is the band still clean,
without traces of intermodulation ?

Thanks,

GREAT Simon.

Do you own an Airspy R2?

Could you make a A<>B comparation on 137 mhz?

I am using my R2 at 10MSPS and 64 Decimation.
With this i have a very low Noise Floor and GREAT SNR Reports.

Thank's a lot.
