Re: Welcome 2895

 

Welcome Thad I will be on the look out you. I use FLDIGI and it's a shame it does not have a call sign alert. I never could get the alerts to work in HRD. I just gave up HRD for all the bugs and not member alarms for our PODXS members.

Correction 2895

Jim K5SP
 

Earlier today I sent a Welcome message to the group and it was incorrect.  The subject line had the correct member number, but the text had the wrong number.  So her is a correction.

Welcome

2895 Thad KN4TFR

My apologies to all.

Yep, it is hard to believe, but Jim, K5SP, the Executive Director of our beloved PODXS 070 Club has actually found time to accumulate sufficient QSOs to grab the LONP 800 Level!

Congrats to Jim and many thanks for your dedicated efforts to ensure all members can enjoy this great group of dedicated PSK operators and friends!

Give him a fist-bump next time you see him on the waterfall.

Next milestone, 1,000!

Re: PSK31 split operation

Eric KG6MZS
 

What's funny about that George is that the new versions of WJST-X can decode 3 or more signals from the same trace.  I guess the software initially decodes the strongest trace and then subtracts it from the pile and decodes other signals from whats left over.

Very different from PSK in that several signals usually renders all undecodable.  I've noticed that If I want to work a station on PSK that is getting a pileup of responses, just moving over a few hundred hertz will sometimes get me acknowledged from skilled stations.

This underlines another feature of split - the running stations needs to announce they are listening split -- unlike FT8.

Thank you.  A pile-up is one thing and I can see the reasoning on that.  On wsjt-x, the rationale is that the Tx signal is narrow band; minor distortion (near the edge of the Tx passband filter) reduces likelihood of a decode, so wsjt-x sets the split and adjusts the audio offset so that the Tx is at the exact same frequency as Rx, but is now in the center of the Tx passband. It seems like the same logic would apply to any narrowband signal. Of course, as was pointed out, the PSK band is usually not crowded and you can pick a frequency in the middle.

I'll echo Stephen's sentiments.  I've seldom needed to use split for PSK because the PSK waterfall just isn't that crowded.

In Digital Master 780 it's pretty easy to set up split.  Just set up on a clear frequency and lock it, then move the receive cursor over to the station you want to work.  I usually center my TX frequency in the waterfall.

Re: PSK31 split operation

Stephen Melachrinos <melachri@...>
 

George -

Avoiding distortion is always a good thing, but I haven't seen PSK31 get distorted enough near filter-band edges to lose decode. I lose the signal power before I see a distortion.

Perhaps the m-ary FSK underlying the JT modes is more sensitive than PSK.

And remember that with splits in the few hundred Hz, proper positioning of your signal (as Eric suggested) should keep the received signals away from filter-band edges.

Re: PSK31 split operation

 

In Fldigi you do it as Eric explained to do it in DM780, use the lock button which is down at the lower right of the screen.
