It could be Gary and I think it's fair to say that propagation simulators are just not capable of capturing all the variables of the HF channel. They do, for the most part, capture the fundamental characteristics of the real thing and that has been proven to be useful when comparing the performance of different HF modems. As far as NVIS, the simulator creates a multi-path condition that tries to emulate both ground waves and sky waves arriving at the receiver; a condition that can destroy throughput with certain modes regardless of how strong the signals are. NVIS field tests would have to meet this criteria in order to prove or disprove whether an NVIS path simulation was useful in determining which modes work best for this kind of propagation. The trick is recognizing the presence of both ground waves and sky waves. I doubt if there's enough ground wave signal strength to cause any real problems on the longer NVIS paths; it's the relatively short paths that give the most trouble and of course, that depends on terrain, antennas etc. Thanks for the input Gary. I'd be interested in any NVIS recordings you have.

Re: [digitalradio] Re: PSK-ROBUST - Path Simulation Results vs field tests
For ARQ there is an additional criterion, viz. the value to look for is the thin border line between 95% and 100% copy. 95% copy is generally not enough for efficient ARQ operation. That is why pskmail does not use S/N levels as the only parameter for switching modes, additionally we use block size adaptation and ARQ success. Using this the MFSK and THOR modes get their fair share of the cake under NVIS conditions. Rein PA0R Gary, Thank you for the feedback. Using ARQ systems like you did we have also noticed that faster PSK modes show better performance as in less repeat request than slower ones. Your first theory is the one we believe is the most likely contributor for the ARQ links in general benefiting from faster psk speed (up to a certain point of course). But like you we are a bit puzzled by the apparent robustness of these modes in NVIS conditions. If you are so inclined, could you please perform a comparison between psk250 and psk250R as available in the beta version 3.20 of Fldigi? The FEC of course reduces the speed by almost half but the error rare (ARQ repeats) appears to be lower than even the half psk speed (i.e. psk250r seems more robust than psk125) as Rein reported in his post on this subject. Another perspective would be appreciated. 73s, John --- In digitalradio@yahoogroups.com, Gary wrote: Your question is one that I have also.

INTRODUCTION AND BACKGROUND I write to you, as a very active operator in USA's Amateur Radio Service, and in my capacity as International Coordinator for the Global ALE High Frequency Network, a 24-7-365 interconnected network of hams operating simultaneously on all international HF bands for the past 3 years. I have presented papers and participated in expert panels at Global Amateur Radio Emergency Communications (GAREC) and other HF Conferences, on the subject of international emergency / disaster communications and HF Automatically Controlled Data Station innovations. I have worked with groups and nets of digital and analog modes to achieve voluntary HF net coordination. I maintain a survey of HF band activity and a comprehensive up-to-date international ham radio bandplanning resource at http://hflink.com/bandplans MOTIVATION AND HOPE FOR A NEW HF BANDPLAN The motivation for this correspondence is the hope that the ARRL Representative to IARU Region 2 bandplanning committee can work aggressively toward a better bandplan this year, especially one that is both compatible with USA's FCC Amateur Radio Service rules, and designates adequate spectrum space for automatic fast data stations. The previous plan had many many errors, mostly due to essentially being copied from an old IARU Region 1 bandplan, without regard to appropriateness for Region 2 hams. THE EMCOMM BACKBONE: HF AUTOMATICALLY CONTROLLED DATA STATIONS HF Automatically Controlled Data Stations have become a vital lifeline for many stations in remote areas of our IARU Region. The networks of ham operators that use and keep these fast data stations on the air daily have become the main backbone of emergency/disaster HF communications in the North American and Caribbean area within recent years. A huge community of hams is being served daily by HF data networks, especially with email and short text messaging, resulting in thousands of contacts per day logged on a steady basis. Recent developments in soundcard ARQ digimodes has brought fast HF data within the budget of almost every ham in the Americas. During emergencies or disasters, this fast data traffic increases exponentially in the extremely crowded automatic bandplan segments. REGION 2 LEADS WORLD IN HF FAST DIGITAL DATA EMCOMM NETWORKING It is a well known fact that IARU Region 2 has a much higher use of HF Automatically Controlled Fast Digimode traffic than the other IARU Regions (supporting network logs are available to the representative on request). Due to high speed ARQ, these efficient data communications using normal 2700Hz bandwidths are able for time sharing spectrum for traffic more effectively than slower digimodes. However, the previous HF bandplan for Region 2 failed to designate adequate band segment space to enable these essential modes for the present and future of daily routine and emergency/disaster communications for amateur radio. Operators need the flexibility of 2700Hz bandwidth to run as fast as possible so that more operators can run their traffic rapidly and promptly. ARRL was founded in support of traffic handling, and the new fast digital networks are actively carrying on this tradition of volunteerism and high quality. PREVIOUS REGION 2 BANDPLAN ILLEGAL FOR 90% OF HF AUTOMATIC STATIONS USA amateur radio operations are greater than 90% of all HF activity in IARU Region 2.

15% of the HF bands for automatic data stations that serve no more 1% of the hams in the US or 0.3% of the hams in the world? I DON'T THINK SO! In times of real emergencies, ALL frequencies are available for emcomm.

Re: [digitalradio] KQ6XA Recommendation IARU Region 2 Bandplan to ARRL
The ARRL deadline for comments/suggestions was April 5th. I wonder why Bonnie waited until the very last minute to submit her suggestion to the ARRL? Could it be that she anticipated a backlash against the 15%+ proposal (her suggested band plan gives 50% of 30m to fast/automatic stations!) from other amateurs that do not share her passion for EMCOMM? By waiting until the very last minute, she effectively prevents anyone from commenting directly for or against her proposal. Kudos to Bonnie for her political awareness and for knowing how to work the system. Now, regardless of the deadline, I'm going to be sure to send in my two-cents worth.

I bet Patrick could make that happen. 15 seconds of either mode. On the other hand, maybe I should give up on the ALE400 concept and encourange everyone to scan/sound (while attended) with ALE 141A and switch to appropriate digital modes as conditions suit. I think you're on the right track Andy. The ALE-400 mode is certainly more spectrum friendly. We have all the hardware / software tools we need; the only thing left is participation.
