Geo Diversity

Will bring us the V2 Geo Diversity or is this theme lost ?

KY6LA_Howard

I do believe it's on the enhancement list for a future release but unlikely to make it into the Zero release (2.0) of V2 Your guess is as good as mine as to when

Michael Aust

Kinda like Lost in Space ?

What is Geo Diversity?

Chris DL5NAM

Ria, connecting of 2 RX  - like we have with now with Diversity but Geo means 2 RX on different locations connected via WAN.

Every RX need the GPS extension for time stamps - .... then left ear / right ear

It's also a kind of remote but with 2 radios (master/****)

Aha... seems like a neat feature. DXCC and other awards won't like it (contacts won't be valid) but it'll be interesting to see it in action.

Chris DL5NAM

DXCC dont like it?
WEBSDR.ORG is nothing else - so it's not new. Only if you have 1 VFO knob for 2 RX (real RX = Flex and not any cheap SDR sticks :-)
I am talking only about RX - remote operation will be with SSDR 2.0 not a problem

Ria

Yes, it's against the rules. People probably do it, but in the end it's an honor system, and if you want that plaque up on the wall to mean something you stay within the rules. For contesting it's definitely a no-no and can and will get you disqualified. 

It's DXCC rule 9.a and b if you're curious. 

Remote operation where transmitter and receiver are in the same physical location are OK though. 

Chris DL5NAM

Yes, your right. Also using more then legal power, ESSB and ....

c) QSOs made with legally licensed, remotely controlled stations are allowed to be used for DXCC credit.

(have confirmed 331 - but no DXCC award :-)

Ria

Yes, as long as the remote is in the same DXCC entity and within a 500m circle. So you can't operate 4U1UN with a remote receiver outside the gate for example. Or you can't transmit from Europe and listen in North America. Well, you can, but it's not valid for DXCC. You can operate my station remotely from Europe (provided you have a US license) and work DXCC that way. Ria

Ria, i am concern in new technics. Not cheating any others = myself.  Most countries have CEPT so i do not need a US call sign to work from USA.

But thats not my target, but compare 2 QTH (antennas) or check prop or my signal there will be fine.

For me it will be a playground - not a way to get an DXCC or contest advantage.

Ria

According to the information I have from ARRL, CEPT doesn't cover remote operation. Either way remote services here such as RHR require a US license to cover themselves, and I would as well.

However anyone can get a US license if they so desire. I would even let anyone who wanted use my PO box as their address.

Just like regular diversity where the signals from two different antennas fed to two SCU's in the same radio and combined to improve reception, Geo-diversity combine signals from two different receivers for improved reception. With precise time stamps provided by the internal GPS in the VITA data packets receivers anywhere in the world could be combined.

GPS time stamp in vita packet

that may interesting for TOA  localisation  of interference or else

Chris DL5NAM

Yes, it's like lightningmaps.org since many, many years work for exact lightning strike detection.

Geo Diversity will be a feature for Flex that most of the other pseudo SDR TRX not will have

Tim - W4TME

This feature is still on the "wish list".  Currently, it isn't planned for inclusion is a major release.

Chris DL5NAM

Any changes visible ? :-)

Chris, given that this thread was brought up 3 years ago my first thought is, it's not a very high priority.  It sure would be nice if SSDR had the same Diversity adjustments as PowerSDR. 

In any case, thanks for bringing the issue to the surface again.  Hopefully Diversity receive improvements have moved from the wish-list, to something closer to reality now.
