[digitalradio] PSK500 mode
Andy, Im running fldigi 3.13AU but I cant find PSK500 on the list where can I find it, for PSKmail... On my puppy mail server is working, I just completed testing makeing sure it can pass emails.. Now on to PSK500 mode ?

Re: [digitalradio] PSK500 mode
Hi Russel, Its not on 3.13AU, there is a patched version with PSK500 but it wasnt there on AU from the start. I guess AZ is the latest now and its on there (its what I run here). 73 de Per, sm0rwo From: Russell Blair russell_blai...@yahoo.com To: Digital Radio digitalradio@yahoogroups.com Sent: Thu, October 29, 2009 5:22:22 PM Subject: [digitalradio] PSK500 mode Andy, Im running fldigi 3.13AU but I cant find PSK500 on the list where can I find it, for PSKmail...

Tnx Per well 3.13AU is whats in my puppy mail CD. Ok thanks for the info.

[digitalradio] PSK500 testing
I am active with a PSKMAIL server on 10147 (dial, 10148 center frequency) testing PSK500 with RSID. If you send an RS ID I should change at my end and allow you to connect at PSK500 K3UK

So, where are people using PSK500, on VHF ? Is it mainly for message transfers? Andy K3UK
Re: [digitalradio] PSK500
I am testing PSK500 on HF at the moment. It fits nicely in a 500 Hz filter, and is lightning fast on a clean link... I can see it used only for arq message transfer, with automatic fallback to slower speeds and bandwidth...

Re: [digitalradio] PSK500
Thanks Rein. Is there a PSK2700 ? That would certainly get Peter Martinez's eyes rolling.

Re: [digitalradio] PSK500 **Minimum SNR - Fast vrs. Slow PSK Modes**
Andy, Thanks Rein. Is there a PSK2700 ? That would certainly get Peter Martinez's eyes rolling. I agree, he would roll his eyes but the throughput would be lightening fast! I tried to get Mixw to run at very high speeds a while back just to see if it would work. It did, but it seems to stop printing at PSK625. The path simulator indicated that the minimum signal-to-noise threshold increased by roughly 3db each time the word-per-minute / baud rate was doubled (see below). It would be interesting to test PSK63 vs. PSK625 on VHF to see if that wide 10db difference shows on-air. It should take 10 times the power to maintain the same throughput according to the simularor. Difficult to prove on HF with all the variables; bandwidth is 2K-plus. Mode Minimum SNR PSK31. -10db PSK63-7db PSK125..-4db PSK250..-2db PSK500.+2db PSK625.+3db Tony -K2MO
Re: [digitalradio] PSK500 **Minimum SNR - Fast vrs. Slow PSK Modes**
If you go much above a 2 Khz bandwidth, you're going to start ruling out a lot of rigs that don't have the audio bandwidth to pass that wide of a signal. I wonder how PSK 2000 would compare with esisting modes, such as Olivia 32/2000 and MT63 at 2 Khz bandwidth. BTW, your figures seem to indicate that the product of gain times bandwidth is roughly a constant in an entire HF system, just as it is in a transistor amplifier. --- Dave Sparks AF6AS - Original Message - From: Tony To: digitalradio@yahoogroups.com Sent: Saturday, October 24, 2009 4:36 PM Subject: Re: [digitalradio] PSK500 **Minimum SNR - Fast vrs.

I should hame mentioned Olivia 64/2000, instead. I seem to remember that FLARQ won't work with Olivia for some reason, but I'm not sure about jPSKmail. Reading the specs on these modes, they actually sound a lot like spread spectrum. -- Dave Sparks AF6AS Riverside, CA, USA (DM13gw)
