Extended message and RS ID #Multipsk

Patrick Lindecker
 

Hello Sholto,

 

>MultiPSK has a tcp/ip interface. It might be possible to use a custom application for RS-ID QNI?

Yes, the reception of a RS/ID (in a 44 KHz bandwidth maximum) is sent to the TCP/IP link (as the form of a comment) .

Note: QNI worth for what?

 

>I wonder if simultaneously received RS-ID symbols (separated by frequency) would be decoded? This would help a lot to overcome any doubling which is a common problem.

For RSID, strictly simultaneous no (it would be a very rare event).

However for EM, it can be received any number of extended messages (EM) strictly simultaneously, as it is programmed for.

Andy:

 

The Extended Messaging feature in Multipsk would certainly speed-up the check-in process. It takes a few seconds to pass along ones status and call sign. The RS-ID protocol has plenty of sensitivity for the weaker check-ins as well.   


Check-ins would pop-up in both the waterfall and EM Window which is pretty convenient for the net control operator.

Me , again. On my old topic of faster/easier net call-up methods.  As you may remember I think many NBEMS Olivia nets take FAR too long checking in stations (20 minutes of checking in, two minutes for net content ) . I did consider FSQcall and JS8Call as offering a better way to start an NBEMS net before switching to Olivia and FLAMP methods for traffic sending. Now I'm wondering if FT4 , or even FT8, offer something more efficient?  Both FT4 and FT8 offer the ability for Net Control to simultaneously detect stations checking in  over a 3 Khz range. Plenty of bandwidth for 20-30 NBEMS stations to check in and be "spread out" .  With FT4 , checking in could be done via a couple of 4.5 second cycles , with FT8 , 12 seconds. I'm also wondering about the "Fox and Hound" setting in FT8 (not implemented in FT4 at the  moment) and whether this could be used by a NCS to quickly acknowledge, en masse, the stations checking in. With WSJT-X and Fldigi open at same time. WSJT FT modes could be used to check in all stations within a minute and then use TX RSID in Fldigi (or Multipsk) to send traffic in the more  traditional, speedier, robust, digital modes.
