Re: Why you should avoid RG-58

Technically interesting and useful post. (i live in urban environment and I know all those kind of noise...) I use coax I find from the local TV store... "Fte maximal k290 w", in their specs they say Screening factor (30-900 MHz) > 90 dB maybe it is a little optimistic :lol: What about lan...

Re: RSP1 and 14 bit resolution

So, dear tech support, you are saying, in other words, that there is no use in tweaking the "new" decimation parameter that I see in the last (4.1) extIo dll for RSP1? By the way, that parameter refer to some "software" decimation processing outside RSP1 or to a feature inside MS...

Old to RSP1, new to SDRuno, need help!

Hi all, users and support team members. I'm new to SDRuno. I have consolidated experience in other software (mainly sdr# coupled with many plugin, decoders and tools), with RSP1, FCPP, RTL-SDR. Now I believe it's time to exploit my old and loved RSP1 to the maximum. I need some help with SDRuno, I w...

Re: RSP1 and ExtIo 4.1 and Decimation

Using arrows now I can change those values...
Thank you very much for the trick.
Now I can start testing what setting is best for me.

Re: RSP1 and ExtIo 4.1 and Decimation

My test case follows this sequence: 1. set the if mode to zero IF 2. set the if bw 200khz from the drop down list 3. set the SR 8.00 from the drop down list 4. set the decimation from the drop down list (if any available...) 5. read the "info" about the final SR reached Right? Any way I wi...

Re: RSP1 and ExtIo 4.1 and Decimation

Hi Tech Support, thank you for your answer. ...You should be able to enable a decimation factor of 16 with an 8 MHz sample rate if you have first set the IF bandwidth to 300 kHz or less... I'm sorry not to be clear. Sorry for my bad english. Anyway what i wanted to do is exactly what you say: IF 200...

Re: RSP1 and ExtIo 4.1 and Decimation

edit:
for some strange reason I succeed for a while to "unlock" the decimation drop down list...
so I got
zero if
if bw 200 khz
SR 8.00 M
decimation 16
unfortunately it was only for a moment...
I did click somewhere else and now it is again locked...
anyone has the same issue?
