Re: [digitalradio] Re: FT-450 on digimodes
I must say that I agree with Bonnie - this is either a poor radio design or more likely you've got a 'duff' radio. I don't think the SignaLink is the problem. Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: expeditionradio expeditionra...@yahoo.com It is not normal specifications to have 12dB tilt (or more) within the passband of an SSB transmitter. The engineer's response to your measured graph of power vs passband frequency indicates that either the engineer is BS'ing you, or the engineer is unqualified to determine the problem.
Re: [digitalradio] Signalink USB Problems

Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: Leslie Elliott denalid...@gmail.com Thanks, I kind of figured it out myself. There was a QSO I was listening to later, which switched from PSK to MT63. However, I could not get a decode after they switched. I'm using DM780, and try as I might, carefully adjusting the trace back and forth to try to center it on the signal, I could get nothing but gibberish printed out. Don't know what was the problem.

Also if a strong correlation is detected, one does not need to wait another 1 second for even stronger signal, because this is highly improbable. I believe Patrick's MFSK is doing both.

Re: [digitalradio] Re: Olivia mode comparisons, testers needed.
The lag is in the software - it's part of the design for the error correction. Where error correction is part of the design then *in general* with Ham modes you have to wait a while before text is decoding is the error correction is applied. The lag is not caused by CPU load. To really understand this it's best to analyse the Olivia design although this can be rough for the brain :-) Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: captcurt2000 [EMAIL PROTECTED] 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..
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. Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: captcurt2000 [EMAIL PROTECTED] 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?
Re: [digitalradio] Decoding differences
Nope - the code is almost the same - it'll be soundcard calibration issues. Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: Cortland [EMAIL PROTECTED] Just this morning I came across a net running in Olivia 8-tone/1000Hz. It decoded poorly in one SW package, better in another, and best of all in a third. I think this must be due to the decoding algorithms of the software packages, as I get different rankings in other modes.
[digitalradio] Windows Only: Soundcard Alternative
This is a windows-only question. It a SDR application were to make data available for use in digital mode programs using something other than a virtual soundcard, what options would be feasible? TCP/IP server? Mailslots? I want to be sure that I haven't missed the obvious here. Simon Brown, HB9DRV www.ham-radio-deluxe.com
Re: [digitalradio] Sound card question
It means that the drivers are better - the internal clock runs at 48kHz, other rates are created by either the driver or (very often) Windows. Windows XP does not do a good job of this, VISTA however is excellent at converting the sample rates. Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: Dave 'Doc' Corio [EMAIL PROTECTED] I've calibrated my sound card (Diamond PCI) two ways, using MMSSTV at 48000 Hz, and MMTTY at 11025 Hz. Here are the results of the calibration: MMSSTV 195 PPM 48009.37 MMTTY 6984 PPM 11102
Re: [digitalradio] Re: Sound card question
A significant difference between TX and RX can result in an offset. During my holidays in Oct / Nov I will add full soundcard calibration for all modes in DM780. Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: Dave [EMAIL PROTECTED] What impact, if any, does the error in sampling rate have on any TX/RX offset? During the Tara Rumble I noticed that almost every station that responded to my CQ, came back a bit lower in frequency than mine. One station I responded to even told me I was off- frequency. I don't believe my IC-746 has any offset, and my RIT/XIT was off. Does that large error rate of 6984 ppm create an offset, and can I determine how great it is?
Re: [digitalradio] Comparing data modes
Dave, IMO any data program will be talking to the soundcard with a nice big FIFO so CPU shouldn't be an issue. From memory I use a 10 second FIFO on receive and 2 second on transmit. I can't think of any problems that could arise as long as there are some free CPU cycles. What am I missing? Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: Dave AA6YQ If you're referring to CPU usage as reported by the Windows Task Manager, that's an average. The question is whether any app is being starved for CPU resources during critical operations.
Re: [digitalradio] Comparing data modes
DM780 samples at 8kHz and has a lot of encoder / decoder code in common with fldigi. MT63 / Olivia having being taken from Pavel's original code. I'll try to find the Microsoft Blog entries which explain why some rates such as 11,025Hz are so poor with W2K / XP but not with VISTA. It's not a compromise - anyway with luck I'll find this explanation this morning. FWIW I generate 8kHz from 48kHz sampling using Moe's code. Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: Dave AA6YQ Also, there is no reason to believe that the two applications would be equally penalized by a compromise sampling rate -- so the results of the comparison would be suspect unless its known that both applications use the same sampling rate. -Original Message- From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of Dave AA6YQ Its my understanding that when multiple simultaneously running applications are using the soundcard with different sampling rates, that Windows delivers a compromise sampling rate. Thus comparisons run on the same PC may not accurately reflect each application's performance in isolation.
Re: [digitalradio] Comparing data modes
I'm sure fldigi uses 8kHz in general and 11,025 when needed for some Thor / DominoEx modes. Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - The sample rates were 11025 Hz for Mixw and IZ8BLY MT63 terminal. Looks like 8000 Hz for DM780 and Multipsk. Not sure what's going on with Fldigi. I'm using the Vista version.
Re: [digitalradio] Sound Card general question
- Original Message - From: Dave [EMAIL PROTECTED] When I got my current sound card, the first thing I did was to run the various calibration routines from MMTTY, DM780, and MultiPSK. These calibration routines showed the card was off by 181 parts-per- million. I set up the various software accordingly and all was well. This offset shouldn't really have a big affect - I would be wondering about squelch levels or even the soundcard. What is the soundcard? Internal or external? RTTY is nowhere near as good as PSK when it comes to weak signals. I've encountered someone with a soundcard running in surround mode :-( Simon Brown, HB9DRV www.ham-radio-deluxe.com

Re: [digitalradio] HRD: Script error when running DX Cluster

Re: [digitalradio] Re: Has anyone looked into FPGA-based digital modes?
As Dave says, Make the modulator and demodulator available in a form easily incorporated into existing digital mode applications This is so very important. Olivia / MT63 is easy to implement because Pavel made source code available. If the source for a new mode is available in a commonly understood language then it has a very high chance of being adopted by the software developer community. If there is just a vague specification then speaking for myself there's little chance that I'll try to add it - I work in what little spare time I have, the prospect of banging my brains on the desk doing this sort of work is not at all appealing.

FWIW http://psk.gladstonefamily.net/cgi-bin/pskstats.pl (see also http://psk.gladstonefamily.net/pskmap.html ) Well over 25,000 distinct callsigns seen on PSK over the last three months. I doubt anything will overtake PSK in popularity in this decade. Simon HB9DRV -- From: Dave Bernstein [EMAIL PROTECTED] Metcalfe's Law states that the value of a telecommunications network is proportional to the square of the number of users of the system. I suspect that it also applies to digital modes.
Re: [digitalradio] Multiple Digital Modes: Time to get rid of most ?
Interesting because I've been asked by quite a few people to add Hell to DM780 - which I have done, so expect some Hell activity this year. In general I agree that we possibly have far too many modes, for the beginner it's no easy to know what's what. At least PSK / RTTY is a good starting point. And real SSTV - that's very active although not a true digital mode. Simon HB9DRV -- From: Andrew O'Brien [EMAIL PROTECTED] Maybe it is because I am getting irritated because of the pinched nerve in my neck, I'm thinking maybe I have just had enough of the plethora of digital modes. Yes, it is K3UK saying that...the bloke that is always trying varying modes.
Re: [digitalradio] Re : Best line of the day
Maybe because I'm further south but 20m has been very stable all day on PSK. Simon Brown, HB9DRV -- From: Mel [EMAIL PROTECTED] I would have thought by now, with conditions having been the way they are for some considerable time, all users would have seen strong transmissions, suitably described as 5/9, within seconds deteriorate into barely readable signals.

One other thing - at the moment it's only PSK, when Philip has his act together it will support any mode, for example SSTV. Simon Brown, HB9DRV -- From: Simon Brown [EMAIL PROTECTED] I think you mean: http://www.obriensweb.com/pskr.jpg
Re: [digitalradio] PSK Reporter in DM780
This is just detecting callsigns in on-air QSO's and receiving reports from new logbook entries, that's all it does. No beacons or automated transmissions. Simon Brown, HB9DRV -- From: Rick [EMAIL PROTECTED] If this is used by very many hams, then how does this impact the PropNet beacons?
Re: [digitalradio] PSK Reporter in DM780
-- From: Rick [EMAIL PROTECTED] What is it the PropNet does now that is different, better, etc.? I have no idea - I added this PSK reporting in DM780 for Philip so that he could 'do his thing'. I guess one advantage is that the user just bats about as normal having QSO's and stuff rather than specifically running PropNet software. For the user it's 10 seconds to configure this with a simple window and then it's set and forgotten. When you do or see something it's automatically reported. Simon HB9DRV

Re: [digitalradio] Logging for MultiPSK and DM780
Maybe use DXKeeper from Dave AA6YQ? I know there are interfaces in DM780, sure-ish that they exist in MultiPSK.

Re: [digitalradio] Re: Logging for MultiPSK and DM780
BTW - I have a fine NTPClient class in C++ in case anyone is interested, I use this when calibrating soundcards and also to keep my computer clock updated every 15 minutes. You would have to modify it yourself as it uses a few DM780 calls but the intelligence you need is in place. Simon Brown, HB9DRV - Original Message - From: Simon Brown [EMAIL PROTECTED] Also I would say that UDP is easy in all languages, DDE is a tad complex in C++.
Re: [digitalradio] Re: Logging for MultiPSK and DM780
An advantage of UDP is that the logger could be on another platform / computer. Although there's network DDE I have never tried it and don't want to try it to be honest. Also I would say that UDP is easy in all languages, DDE is a tad complex in C++. Simon Brown, HB9DRV - Original Message - From: kh6ty [EMAIL PROTECTED] Dave, over five years ago now, I pushed for using a standard DDE interface for all PSK31 programs so anybody could use his favorite logging probgram with his favorite PSK31 program, and developers did not have to keep reinventing the wheel. It also found little interest. :-( I'd still like to see that happen. The need never goes away!
Re: [digitalradio] Re: New release (4.7) of MULTIPSK
To be able to provide the remarkable number of modes in MultiPSK *and* have a UI conforming to the Windows usability guidelines is verging on the impossible, especially once you factor in supporting users and maintaining websites. IMO the user community should be very grateful to Patrick for the work he does no matter how appealing the UI may be. To provide the ultimate software would require a team of three or four programmers; herding cats would be easier.

[digitalradio] rfsm-2400

Re: [digitalradio] Re: rfsm-2400
Hi Dmitry, Sorry about that, reading your website it is easy to think that there is no freeware version - it is not obvious as the first line of your website says that RFSM-8000 is shareware! Maybe you could add this RFSM-2400 freeware information so that everyone can see it easily? The reason for an open source code is so that the RFSM concept will be more widely adopted - this is why PSK, MFSK, Olivia is so popular - it is very easy to write a program using a high-performance engine. It is also educational, an important part of Ham Radio. By comparison HamDRM source is available http://hamdrm-dll.googlecode.com/svn/trunk/ - I have downloaded and compiled it, I hope to use it soon in digital SSTV. Simon Brown, HB9DRV - Original Message - From: dmitry_d2d [EMAIL PROTECTED] I About shocked price. 1. RFSM-2400 is FREEWARE. II About open source. Why have you decided, what you can get source codes free, when they are the result of several years of work of group of people? People suggested to buy them for the rather high sums :).
Re: [digitalradio] Re: General questions about SSTV/Quick Guide
I see some use of MixW here, also little talk on the SSTV 20m frequency 14.230. DM780 coming along well with analogue SSTV support, crashing merrily at the moment :-( Simon Brown, HB9DRV - Original Message - From: Andrew O'Brien [EMAIL PROTECTED] I have had the same experience as Rick, some helpful hams but some grumpy hams on the usual SSTV frequencies. Also, too much talking. Like, one picture sent and 5 minutes of chit-cat. Like some of the less-used digital modes, SSTV is only used by a small amount of hams, and you tend to run in to the same few hams over and over again.
Re: [digitalradio] Re: Redefining SSTV operations

Simon Brown, HB9DRV - Original Message - From: Leigh L Klotz, Jr. [EMAIL PROTECTED] Patrick, Yes, but MultiPSK and DRM780 and fldigi and other programs already support MFSK and other modes.
Re: [digitalradio] Re: Redefining SSTV operations
It could be done in 500 Hz - why are you looking for the 500Hz bandwidth? Simon Brown, HB9DRV - Original Message - From: Leigh L Klotz, Jr. [EMAIL PROTECTED] I didn't know it fit iin 500Hz. I will go look again. This is JPEG2000 coding? If it fits, it is more interesting than MFSK's analog mode, but MFSK's analog has the deployment advantage.
Re: [digitalradio] FIR Filters
Hi Sergio, I am able to design using Parks-McClellan and to be honest I think my UI is better than ScopeFIR's. What I would like (but not essential) is the ability to take my filter coefficients and validate them with another program. I don't see this in ScopeFIR, although I could possible write my own code to do what I want I need to validate my filters with a program not created by my own fair hands :-) With a filter covering 0 to 4,000Hz I simply feed a signal in, see what I get out and do some sums... Simon Brown, HB9DRV - Original Message - From: [EMAIL PROTECTED] I have tried ScopeFIR so far.

Re: [digitalradio] FIR Filters

Re: [digitalradio] Pactor3
Hi, Yes - Patrick's idea is on the to-do list along with PSF63F. At the moment I am working on SSTV with the aim of having a beta inside three weeks. Although SSTV is analogue it's a great weak-signal DX mode and really quite interesting from a retro-viewpoint. Simon Brown, HB9DRV - Original Message - From: Sholto Fisher [EMAIL PROTECTED] I was wondering if you had thought about including Patrick's Reed Solomon detection feature in DM780? I realize DM780 doesn't have all the modes MultiPSK has, and DM780 has Throb-X 4 baud which MultiPSK doesn't - but if you just had the recognition part for the modes in common I think it would help a lot of beginners to the digi modes understand what they are seeing/hearing.
