Re: HF+ Questions

Tony, I'm just an idiot (a happy idiot, but an idiot nonetheless) so I don't know how such nebulous processes as quantization and decimation are specifically capable of improving the noise floor (and

Re: HF+ Questions

Simon, Maybe somebody else will comment on the assertion that ADC width doesn't matter. I will leave it at that. Tradeoffs must sometimes be made. Tony ad0vc

V3 RDS

Hi Simon, Is there any chance that you could implement RDS logging in a future release please? Many thanks Mike

Re: HF+ Questions

OK, 768kHz from the radio, my software also provides 394, 192, 96 and 48kHz USB only but of course supported by servers including SpyServer ADC bits doesn’t really matter – MDS and Dynamic

HF+ Questions

I looked at the Airspy site and read what they had on the HF+. Some info seems to be missing: What sample rates are supported? All I see mentioned is 768Khz Can it be connected with USB or is it

Re: HF+ Comparison

There are differences in windowing techniques. You have a tradeoff between spectral bin leakage, sidelobes and resolution. This may make no difference if all you are doing is looking at strong

Re: HF+ Comparison

OK, didn't know whether "Youssef" windowing was unique to the HF+, especially as I know nothing about it. I haven't seen big differences using different windowing for the same receiver, but maybe,

Re: HF+ Comparison

There’s a list of options for Windowing, for some reason I had Youssef selected on the NetSDR. Simon Brown, G4ELI www.sdr-radio.com

Re: HF+ Comparison

understood...but why is "Youssef" windowing being used for the NetSDR?....that's what comes up when I click on the NetSDR screenshots... Thanks again. Nick

Re: HF+ Comparison

Hi, This is the FFT Windowing, see https://en.wikipedia.org/wiki/Window_function Youssef is the brains department at Airspy, he designed his own algorithm. It’s really something for the CW /

Re: HF+ Comparison

Quick question, probably indicating how far I am out of my depth.....but the couple of NetSDR displays I looked at in your link used "Youssef" windowing, which I don't know about.....whereas the HF+

SDR-Console – v3.0 preview 6, cannot edit "Favorites" data

Hi, I can't seem to edit the favorites data in SDR-Console – v3.0 preview 6 . The menu drops down and new frequency data can be entered but it doesn't retain the new values. Randall, KM6LPW

Re: HF+ WX Reception

Well if the HF bands are that bad then am I correct in assuming that you will be testing the Airspy HF+ on 2m EME rather than going to the pub? Paul N2EME

Re: HF+ WX Reception

Simon, Sorry. I thought you told us you sent the hf+ to someone to do some serious testing and that it would return last tuesday. Not trying to push you. Just very interested. Carl
