Anyway, dear friends, let's put it in this way:

Re: Interference identification?

Well this thread must be jinxed...I enjoyed mostly unharmed reception until this weekend but now... :( ... The only thing I care about is "will it go away?". ... Did you try to lower the gain? Did you get the same pattern? ...the authorities... they had "more important work to do&quo...

Re: Interference identification?

Could it be a PLC/PLT modem?

Re: Interference identification?

Thank you very much. It seems that I have this sort of noise but fortunately it is not so strong. That's probably the reason I never realized this was caused by a powerline modem. I just archived that as due to thunderstorm around. In fact I have more noise from other "local" sources: lcd/...

Re: Interference identification?

If I understand well, jpsa posted an image of an idle modem,
in other words those horizontal lines are a sort of hearthbeat to keep in synch the system.

Can anyone share here an image of a full operating modem? I mean, when there is data traffic?

Thanks in advance.

Re: P25 Trunking

I forgot to say... if you use the "old" sdr# build 1361 (+ sdrplay device controller 3.8.3) you can

Re: Interference identification?

The short answer is: I don't know. In the meantime we wait for a noise "guru" to answer... since the noise seems to be "local", have you tried to unplug from main all the electronic device you have at home? Take away all phones, tablets and so on? If you find the answer please sh...

Re: P25 Trunking

You can try with DSD+ (aka dsdplus). You need the following "set-up" (in synth): a front end software supporting sdrplay (e.g. sdr#) --> vb-cable --> dsd+ (btw: unfortunately sdr# do not support completely sdrplay, so, for example you cannot use useful sdr# plugin like "dsd+ plugin&qu...

Re: SDRPlay with SDRuno. Dream not decoding DRM!

... Very frustrating. I am new to this whole SDR thing and most of the decoding programs are a little complicated so ... I suppose all the things you mention (dream, virtual audio cable ...) are ok... ... you do not mention the bandwith you are feeding to dream sw. It should be 10k at least. you ca...

Sigmira supports SDRplay

Sigmira 1r10 (released last month) supports SDRplay. It seems to me a good news and I want to thanks the author S.A. Harlow for this chance for sdrplay owners. I'm a user of Sigmira from long time. Connecting Sigmira through audio cable to a "conventional" rx I had lot of fun decoding hfdl...
