Hi Barry/Barrie This is the long-wire antenna that I have feeding into my HI-Z Port: https://www.ebay.co.uk/itm/SHF-80-The-Winning-Low-Noise-HF-Longwire-antenna-for-SWL-TX/192468332135?hash=item2cd001ae67:g:NkAAAOSwPgxVTQxD I am well satisfied with it (RX only - I am neither licensed to transmit on ...

Hi Barrie I am hesitant to make recommendations based on my shallow experience. However, I have one of these - https://www.ebay.co.uk/itm/MiniWhip-Active-Antenna-Assembled-in-Box-HF-LF-VLF-mini-whip-sdr-RX-portable/222469570201?hash=item33cc383e99:g:YugAAOSwc-tY63MT It works very well (well grounded...

Hi Al Fairly new to this as well. If I understood your post correctly, this is how to do what I believe that you want to do. In whatever mode you may be, simply right-click to the left of the tuned frequency shown in the "RX Control Panel" and a drop-down list of frequency steps will appear. Simply ...

Hi Roger
Have you experimented with he HP Filter control, located within the "Sett" menu of the RX Control panel?
Use either mouse L/R keys or wheel to increment/decrement - this does have a tonal effect.
I hope this may be of help to you.

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 and no dome...

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 electronic device...

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...

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...
