Re: RFI

I'll keep this short as I do understand the complexity of these issues. Just for the record, the "noise humps," previously referred, to are actually present from 5 to 12 Mhz and which were absent yesterday afternoon and evening have reappeared this morning, there is no change to my setup a...

Re: RFI

Thank for the responses. Back in the "classroom" - Hand up: The longwire comes indoors directly to a 9:1 balund - there is an abpprox 5M coax feed inside the room - a converted attic, with only the laptop and power sources, which are always in use - no adjacent televisions or other electro...

RFI

i do appreciate just how complicated this issue is and just how variable local environmental issues (not forgetting self-created ones), but is there any known issue, whether with the RSP or generally that at least throughout the VLF nad MF bands creates 1 Khz spikes? Not that I'm without other issue...

Re: VFO & LO for dummies

Thank you Tech Support (once more) for an explanation that I am almost in danger of understanding. To show that I have paid attention, I have produced two screeshots: 1. zero IF/SR 2 Mhz/Decimation 8 2. Low IF/SR 8.192/Decimation 4 Which confirm the result that you advised - thank you. https://www.f...

Re: VFO & LO for dummies

I know that I am technically challenged, but having tried low IF mode in the MW band, I found that although the "images" virtually disappeared, the stremgth of "wanted" signals fell dramatically also. Disabling IF agc and increasing IF gain manually was pretty ineffective. I will...

Re: Does SDRuno Software Allow For Continuous Tuning ?

Dear Support Thanks once again for a concise and clear explanation - sorry, I'm still learning - now much wiser. I do appreciate the difference between the i.5Mhz ratings and the use of the Hi-Z Port, however, Ports A & B do have the advantage of the MW/FM filter, which I suppose will remain out...

If this works, it's the imge of the spectrum where mouse scroling ceases to tune the receiver (as previously expained (or attempted to).
Appologies forthe previous "Faff."

Re: Does SDRuno Software Allow For Continuous Tuning ?

Well, perhaps googlephotos only allows "authorised" access - sorry about that.
I'll try inserting an image again, when I work out just how to do it.
The link that I posted takes me straight to the image...

Re: Does SDRuno Software Allow For Continuous Tuning ?

Thank you for your responses/interest For me it's not a big deal, more an observation and I only posted my observation in case it was in any way associated with the original post in this thread and perhaps of use to the respected tech folk. I did provide a link to a Google photos image of a screen g...
