Re: Why you should avoid RG-58
What about lan cable? Any experience in that? I happened to read something about twisted pair for rx antenna feed. No experience with that, sorry. Since I use the RSP on UHF too (with the same coax and often even with the same dipole), I'd fear the increased loss, besides practical considerations (...

Re: Why you should avoid RG-58
Good shielding of the coax cable is only one small part of the story. Well, I didn't mean to write a book here. ;) I just felt like elaborating on why exactly RG-58 is bad m-kay, because it came up in some other thread. In most cases sheat waves on the coax shielding are more evil. The only remedy ...

Why you should avoid RG-58
People are often not aware how coax quality is generally more important today, sometimes (or maybe particularly) even seasoned hams and SWLs, because they made contact with the hobby in times when the coax shielding was in fact less of an issue. Many, if not most of us live in houses with lots of mo...

Re: RSP2 with hardware frequency tuning wheel
AFAIK SDR Console supports the T-Mate2 directly. No experience with that tho, about to order it for xmas.

Re: Cable RF pickup.
AFAIK even the good types of RG58 provide a shielding of only 45dBm, so using this in any high-sensitivity application and/or noisy environment is simply a no-go. Use double-shielded 75 ohms sat coax or, to be on the safe side, at least H155 instead.

Re: NDB reception
can you post some details about your loop? horizontal I suppose... Yes, horizontally polarized (so physically a vertical, "upright") loop, center-fed (vis-a-vis the apex) which is not ideal (high main lobe elevation angles), but this way I could easily conceal the coax in the hedge and the loop is ...
Re: Scanner?
It would be best to simply try it (quite easy since you can just copy as many instances of SDR# to your HDD as you want, just put them all into an individual folder). However of course it can stop at busy frequencies and has provisions to log activity time on frequencies it found. There is an "audio...
Re: Scanner?
Paul, you may find the last post in this thread http://www.sdrplay.com/community/viewtopic.php?t=248 useful. That's how you get (among other useful stuff) Vasily's (sp?) "Fast Scanner" plug-in, with the name being a massive understatement. Scan speed depends a lot on IF bandwidth of course, but even...

Re: NDB reception
Glad you get reception "down there" now. :) However, while a miniwhip-style antenna gives surprisingly good results even "down there", a simple wire loop will beat it on many occasions. Here's a comparison of VLF and NDB reception with a dipole vs. a loop of the same wire length. Actually it's the v...

Re: RSP-2 antenna select via Device Control Panel?
Sorry I meant to report this a long time ago, when SDRUno still had a similar behavior, which was fixed later. It seems an unlucky combination of antenna port selection and LNA GR (or the difference in possible GR settings between the SMA and HiZ ports) is not gracefully handled by the ExtIO.dll (al...
