Yes, but I only see 1 slider. Doesn't the R820T2 have 3 gain adjustments (LNA, mixer, & IF/VGA)? Wonder if that's all Simon decided to provide, or is that all that's accessible in the RX-666/888 hardware? My experience is that maximum optimization requires independent access of the LNA & VGA controls (I always leave the mixer at max, as it doesn't seem to offer anything extra after playing with the other two). Then again, maybe with the 16 bit ADC hopefully the front end gain settings will be less critical.

I wish we would all settle on the Forum instead of hopping back and forward between IO and new Forum! It's getting time consuming and tiresome. Maybe time to close the IO Group?
I've been posting all my new questions on the forum. Regardless of what I think, given how much time Simon devotes to SDRC I'm in favor of anything that makes his life easier.

During the day I'm outside and have only access with a smartphone. I can read and save the pertinent emails from the group. Accessing the forum is cumbersome.

I like the group.

I don't imagine I will persuade you, but top right of the forum main index window offers you "New Posts" and "Unread Posts", either of which will quickly in one window tell you what topics are active that you need to read.

Personally I gave up monitoring "groups" by email ages ago. I have enough email coming in without adding a deluge more when the web browser is so much more efficient. One "digest" email a day is plenty!

Anyway, I know this is a subject where everyone is adamant their method is the best so best to leave it there I guess! Just to say I have a feeling from the much reduced posting on here that most are migrating to the new forum and that this IO group will probably slowly decline. Only my opinion of course.

As an aside if you wish to manage multiple tabs in a browser very efficiently and easily (I certainly do it all the time) then for Chrome users try the truly excellent "Tabs Outliner" add-on. It makes saving and recalling dedicated groups of tabs a doddle. Makes "bookmarks" seem totally archaic. I personally could not now manage without it. I only use the free version. It works perfectly well, and no pesky ads by the way, but I have donated to the author as for me it is a "must have":

Re: IDE / ISA TV cards for computers...

Max
 

Not 100% sure of the specifics but I doubt the older cards had better performance than the modern DVB dongles plus your request is so very niche that it would never be worth Simon's effort to add support. You might very likely be the only person who wanted to do it! Personally my WinTV adapters all went to the recycling centre a long time ago, and I would guess for many others too. I admire your resolve to use them though! Just seems like a lot of effort when so many new and easier solutions available.

Do you have anything to get you going on SDR yet? If not, the RTL-SDR dongle is a very good and cost effective place to start. The performance is astonishingly good for an unassuming looking piece of kit, and price is very low also plus of course it works perfectly with SDR Console. This particular model of dongle also works passably well down to HF if that is your thing. In any case it is certainly perfectly good enough to get a nice flavour of what SDR is all about. If you have not got anything at all to start with then suggest you take a look:

https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/

If you don't yet have hardware and also not wanting to buy anything just yet, then the beauty of Simon's program is that you can use it in "server mode". Many others on here have placed their own hardware receivers online attached to a "SDR Server" and you can use SDRC to listen to them remotely. It is exactly as if the hardware was attached to your own PC. Works brilliantly and let's you try all the features of the program out without any hardware investment at all. After downloading SDRC you can be listening to these radios in less than 10 minutes. Excellent tutorial by Kriss Kleigle KA1GJU who also has numerous receivers already running on SDRC Servers to listen to:

https://sdr-radio.groups.io/g/main/message/53082

Don't be confused by title. It means "how to listen to SDRC servers", not how to set up the server end!

Hope it helps.

I've had an AFE822x for several years now. It is supported by SdrDx (Windows and macOS), including the two channel mode (I worked with the author when getting it implemented). Works very well for phasing on the MW band.

The Afedri AFE822x is a dual receiver with diversity capability and there is software to support it in this mode. It has been around for a few years but is not well known.

David,

I agree but Simon has outvoted us:-)
The RSS feed helps. https://forum.sdr-radio.com:4499/app.php/feed
It's not perfect but you get all Forum messages sent by email, unfortunately often without context, delete or save. Click on a message and you go straight to the page on the Forum to respond.
RSS works on most email clients.

VHF (FM band) performance is quite similar to the RSPdx. 8 MHz though.

Re: RX666 and RX888 as VHF receivers

Now that SDRC supports it would like to experiment with the RX-888.

Could anyone recommend a reliable supplier?

Mike B2NS

With the RX-888 I'm buying a lot of capability I don't need, and I've seen
other hardware which promised a lot but was very poorly supported and rather
unreliable (Lime).

But I will be very interested to hear how you get on....
