Andy,
I like your description of those that use WINMOR "WINMORons" ! Certainly describes me for putting in so much time on this full-time "hobby". We continue to make incremental improvements in robustness and throughput..(Rome wasn't built in a day!) but you are correct in the comparisons against Pactor 2 and 3 which has some powerful hardware and 15 years of solid effort with good talent behind it. If we approach even 50% of the P2/P3 performance under similar channel conditions I will consider it all a success. Once the WINMOR protocol settles out I will again make some apple-to-apple comparisons with P1, P2 and P3 across several "channels" on the HF simulator. The motivation for WINMOR was as you said to provide a viable HF ARQ mode and Radio Email client available to those agencies and individuals that could not afford or justify the investment in a high performance HF modem. I am currently testing the next release. It has a few added features and some boost in throughput and robustness. Here is a log snippet I ran with VE1YZ (Florida to Nova Scotia) last evening. 7K byte file (after compression) on 18107.5 MHz, 60 Watts, Trap Dipole antenna. It includes a new metric that measures the peak 1 minute average throughput as well as the session throughput which includes proposal and link turnover overhead. For comparison the peak throughput with P3 (which is ~50% wider bandwidth than WINMOR's 1600 Hz mode) is about 11K bytes/min so on this link WINMOR was running about 80% of the Bits/sec/Hz of P3. 2009/11/01 21:25:36 0.3.1.2 *** Connected to: VE1YZ @ 1600 Hz at 2009/11/01 21:25:36 2009/11/01 21:25:36 0.3.1.2 [RMS Express-0.3.1.2-B2F] 2009/11/01 21:25:36 0.3.1.2 ; VE1YZ DE KN6KB (EL98PF) > 2009/11/01 21:25:52 0.3.1.2 [RMS Express-0.3.1.2-B2F] 2009/11/01 21:25:52 0.3.1.2 ; KN6KB DE VE1YZ (FN84BQ) 2009/11/01 21:26:09 0.3.1.2 FC EM 49F3NSDBH1FA 42046 7172 0 2009/11/01 21:26:09 0.3.1.2 F> 2A 2009/11/01 21:26:09 0.3.1.2 FS Y 2009/11/01 21:27:44 0.3.1.2 *** 49F3NSDBH1FA - 42044/7172 bytes received 2009/11/01 21:27:44 0.3.1.2 FF 2009/11/01 21:27:57 0.3.1.2 FQ 2009/11/01 21:27:58 0.3.1.2 *** Disconnected at 2009/11/01 21:27:58 2009/11/01 21:27:58 0.3.1.2 [Session Stats:] Duration: 2.37 min Bandwidth: 1600 ISS Mode Shifts: 0 Decode Attempts: 130 Weak R-S Decodes : 98 Weak R-S Sums: 0 Strong R-S Decodes: 14 Strong R-S Sums: 0 Bytes Sent : 62 Bytes Received: 7345 Throughput(bytes/min) Session Avg: 3119 Max 1 min Avg: 6082 Estimated Sample Rate Offset (ppm): 91 This release should be out this week. I am still working on some nagging bugs and beginning the port effort to the RMS HF Winlink gateway. Thanks for all your support and help during the beta testing effort. 73, Rick KN6KB
