Re: [digitalradio] Wider digital modes with SignaLink USB
Have you considered building an audio link so you can can take the radios and any possible phase jitter they may introduce out of the equation?

Can you compare to any other interface/rig combination? Have you looked at the constellations of these two programs through several interfaces?
[digitalradio] Re: Olivia mode comparisons, testers needed.
Here is my personal experience comparing Multipsk and DM-780 in Olivia 500/16: DM-780 needs significant more time for synchronizing than Multipsk (the first 2 or even 3 or 4 letters of a call are not decoded in DM- 780). I haven't seen any better decoding by DM-780 under S/N figures down to -10 / -11 dB. 73 Juergen, DL8LE --- In digitalradio@yahoogroups.com, Andrew O'Brien [EMAIL PROTECTED] wrote: Olivia mode comparisons, testers needed.

Andy... I can help out Mon, Tue, and Wed of next week during the day. Also the week of 15 December, 22 December and 29 December... Please advise as to times and frequencies you wish to use... I use OLIVIA 1000hz/32 tones for a MARS digital net I run and we have found it to be very good in weak signal conditions... I'm using DM780 here... I'm running a G5RV that works well on 80, 75 and 40 meters... 73 Al, W8AII/ AAT5DZ Ohio Army MARS

Andy, I can test all software packages any weekday during the mid-day hours or weekends.

[digitalradio] PK-232/DSP manual?
Hi, I just recently purchased a used PK-232/DSP and was wondering if anyone has a manual (with information about the latest firmware ver. 7.2) of this device. Also, are there equivalent alternatives to the costly CSS terminal software? I can't remember the last time I paid $99 for a software program! Thanks! -john W4PAH

How are you going to make sense of the variety of MIPS performance across different testers, or are you just looking for trends. A is faster here than B, etc? I run all but DM780--it doesnt like Win2K and my soundcard/machine configuration. Currently running Fldigi--Win, not Linux.

Re: [digitalradio] Re: Olivia mode comparisons, testers needed.
MIPS shouldn't have any effect as long as the CPU doesn't run at 100%. Olivia likes a calibrated soundcard.

Re: [digitalradio] Re: Olivia mode comparisons, testers needed.
Maybe there would be interest in what some of us sometimes monitor for the NBEMS frequencies of 3584, 7067, 10136, 14074, all with + 1500 Hz audio center. If you have a known frequency, you can even print stations that would otherwise never be copied in the noise. 73, Rick, KV9U Lynn wrote: Andy, I can test all software packages any weekday during the mid-day hours or weekends.

[digitalradio] Re: Olivia mode comparisons, testers needed.
Sooo. a 500Mhhz machine running at 20% is going to perform the integrations and decoding same delay as a 2 Ghz machine running at 20%?? That seems counter intuitive to me.. I'm sure you're right but I don't understand how that can be. I thought the load information talked about resources not speed of execution. Help me understand..
