[digitalradio] Latest on Error Correcting Digital Mode Message Transfers (and WINMOR update)
WINMOR works. It has taken 5 tweaked revisions to the beta version but after a lot of testing and user adjustments I would conclude that it works. By that I mean, you can use this mode to connect to another station and transfer a error free message. The speed at which you can transfer an error message is not particularly good and the mode requires a moderate to good signal between both parties. Given the current propagation conditions and average antennae you can expect data to be transferred between 100 and 300 bytes per minute, a few 400+ bytes per seconds transfers have been reported and one 1000 bytes per second HF transfer is claimed. I am sure than you could probably match or better these results by using NBEMS/FLDIGI or mail transfers with ALE400 or PSKMAIL , but at least WINMOR is making progress. By the way, I saw a email from a PACTOR III user recently that said for WINMOR to be a serious alternative to PACTOR III, it needed to be above 1000 bytes per minute. Since I have never used PACTOR III that is the first clue I have gotten about PIII transfers speeds. I am not sure if PACTOR III requires the same amount of SNR that WINMOR does, but perhaps PIII is more robust under weak conditions. So as I understand it , HF amateur radio operators can transfer messages that have error correction via the following Windows based programs RMS Express with WINMOR (beta): Peer to peer message transfers , attachments allowed. Integration with WINLINK via public mail boxes is planned. Also has Telnet option built in. FLDIGI-FLARQ Peer to peer ARQ email via MFSK, BPSK , and DominoEX. Use of Wrap files also allows for a peer-to-masses error free message transfer. MULTIPSK : ALE 141 and ALE 400 mail and file transfers (Outlook Express intergration) jPSKMAIL with FLDIGI : BPSK, THOR amd MFSK ARQ message transfers via BBS . Some Twitter integration. POP3 Mail capability. EASYPAL: File transfers with error correction. Some peer to masses error correction and fill capability. PC-ALE: File transfers using standard ALE.

[digitalradio] Re: ANNOUNCE: PocketDigi 1.0.12 released
Is there a URL to get the new version ? Andy K3UK --- In digitalradio@yahoogroups.com, Vojtìch Bubník bubn...@... wrote: Hi gang. After nearly two years I finally found time to release an update on PocketDigi. The biggest new feature is DXCC lookup function and distance / bearing calculation. DXCC database from DXLab Suite was converted into a highly compact form and packed into the PocketDigi binary to simplify installation. PocketDigi 1.0.12 is therefore about 200kB bigger than 1.0.11. One could display DXCC information and distance / bearing from the QSO dialog or from RX view popup menu. The distance and bearing information will be more precise if both calls provide maidenhead locator. I created the first official build for Jornada 680, which is the predecessor of the popular Jornada 720. 680 implements Handheld PC Pro operating system on Hitachi SuperH SH-3 CPU. Handheld PC Pro system does not provide notification on device wake up, therefore the waterfall will not resume after the device falls asleep and wakes up. You have to configure your Joranda 680 not to fall asleep when running PocketDigi. Also the Jornada 680 runs at 133Mhz while other Pocket PCs start at 206MHz, therefore one shall be careful not to open too many multiple channels. I implemented configuration on waterfall scrolling direction (up/down/left/right). For visual CW it is convenient to let the waterfall scroll from right to left. I extended configuration choice on waterfall speed and resolution. At slow speeds the waterfall frames are averaged to improve resolution. I plan to add the QRSS waterfall speeds in near future. For the ATS-3b transceiver I added configuration of the PSK31/63 TX waveform timing. The ATS-3b transceiver CW wave has nearly linear on/off ramps. The ramp slope is configured by C42 between source and gate of Q5. The value of 10nF provides transition times about 5ms. Changing C42 to 47nF and setting the PSK31 delay time to 6ms provides a PSK31 signal with IMD 24dB, which is certainly good enough at QRP levels. I fixed couple of bugs and annoyances: There was a bug in RTTY baudot table. H letter following a digit was sent as #. The error was inherited from gMFSK. Saving / restoring parameters of current channel. Next time PocketDigi gets started, the previous frequency, mode / submode and mode parameters are selected. Trimming of whitespaces in QSO dialog. When a call, QTH, name and other were selected in RX window and inserted into QSO dialog using popup menu, the values contained trailing spaces. These spaces were then transmitted by macros. The leading and trailing whitespaces are removed automatically now. 73, Vojtech OK1IAK, AB2ZA

[digitalradio] Transmitter distortion
Thanks for the reference. I downloaded the MFJ-1279 manual, and they have a good point about harmonic distortion and the carrier not being obvious when using a receiver. The RF spectrum analyzer should have shown distortion products further from the desired signal, but it reached a resolution limit with really narrow modes, so I was using the soundcard spectrum analyzers for that. Then you might have to tune the receiver to spot the (unsuppressed) carrier or spot it on the RF SA, since it should be far enough from the digital signal. I didn't use both RF SA and receiver audio SA on each signal type and transmitter, so I may have missed some distortion. Time to look again. I also depended on PSK31 initially, to set the level for MFSK16 and WSPR, since as graham787 sent, they are single tone at a time modes. My audio output to audio input connections were only to make sure the input signal was clean. But there could have been some problems introduced in the connection from computer to transmitter. I used a RIGblaster Plus as the interface, but have started using the RIGblaster plug play since it is smaller, simpler, and doesn't need separate power. I should look at the distortion again with it. And I can check an FT-857D that I just got, and see if it is different. In setting up comparative antenna tests with WSPR, I try to get the two antennas a wavelength apart, and this has been a good time to check for distortion, with enough attenuation. I have also checked when the antennas were 10 or more wavelengths apart. Thanks. Charles Preston KL7OA Messages in this topic (3) 6b.

[digitalradio] Re: Transmitter distortion
Charles: I am interested in seeing your test results on the Yaesu, FT 857. My number 2 radio is an FT 897D that I am using with a Rigbalaster Plug-And-Play interface. The signals from your FT 857 may be similar enough to what I can expect to get from my FT 897 that the experimental data collected from your radio may be in the same ballpark as the signal I might expect that get from my radio. I do not know if that is true - It is just an uneducated guess. With both of us using a Rigbalaster Plug-And-Play interface, signal characteristics might further approximate one another. I have observed signals using no ALC and the tiniest amount of ALC with the FT 897D/Rigbalaster Plug-And-Play combination. My monitoring system is not technically sophisticated. I monitored signals from the FT 897D using a Yaesu, FT 1000D, and SignaLink SL 1+ soundcard interface by observing the signal on a waterfall. The waterfall was generated by the MixW v1.18 software program running on a Dell OptiPlex computer with Windows XP Pro and a 19 inch display. I also used the reverse of the system mentioned above and monitored signals from the FT 1000D on the FT 890D. I did not observe any differences that indicated the quality of my signals changed when I added a slight amount of ALC. We might see different results because the digital mode I used was PSK 31. I would like to see a curve generated by plotting ALC (using a reproducible measurement unit) against distortion.

Hi Tommi; That was our experience as well with RFSM8000 here in Canada. I could pass a 30K .jpg file in about 3.5 minutes under good conditions. I am far from knowledgeable on the US regulations but apparently RFSM runs at too high a baud rate to be a legal mode in the US. It is a pity since it works so well and does pass emails directly to the internet through a gateway . As you pointed out, it requires a pretty strong signal to work. Not sure if any more work is being done on this mode over the past year or so.

[digitalradio] Fwd: D-STAR High-Speed Data Replaces Packet Radio at Twin Cities, MN Marathon [3 Attachments]
- Forwarded Message From: erik westgard ewestg...@att.net To: List for people interested in the D Star repeaters d-s...@lists.twinslan.org; Sent: Monday, October 5, 2009 6:59:54 AM Subject: AX.25 Packet Retired from the 2009 MTCM Project - All Data now D-Star DD Mode After flawless D-Star operation in 2007-2009, the Amateur Radio team supporting the Medtronic Twin Cities Marathon has officially retired AX.25 packet from the effort. We've used D-Star DD Mode now for three years, and we're no longer afraid of the technology said one of the leaders of the project. The five Icom D-Star RP-1D access points installed on Twin Cities building rooftops have been 100% reliable, including at the unusually warm 2007 race, where more than 50 runners were sent to area hospitals. The low data rate, complexity of the character mode interface, and user training issues we have had with packet have put it on the back burner said Erik Westgard, NY9D. Again this year we can sit any available operators or even community volunteers in front of our web based missing runner application and they can be helping family members immediately. One objective for the 2010 team is to start phasing in D-STAR digital voice, who also allows the concurrent use of low speed data. Erik Westgard, NY9D www.14567.org 10/5/2009

[digitalradio] jPSKMAIL update record
I attempted to use jPSKMAIl today for first time in a long time. I was able to easily connect to WB5CON tonight and received a message several times that said Hi K3UK, pse update your record I updated my record by connecting and then configuring mail server settings in jPSKMAIL. I clicked on update settings , received a few bits of info from WB5CON but nothing seemed to happen and the update the record message was sent by WB5CON a few more times. How do I update the record correctly? Also, I understand that WB5CON (or other servers) need my outgoing SMTP but I do not see a place with jPSKMAIL to insert that. I see a place for host , reply address, and password but no SMTP. Andy K3UK --- In digitalradio@yahoogroups.com, Andrew O'Brien andrewob...@... wrote: Anyone want to test jPSKMAIl tonight?

[digitalradio] PSKMAIL does NOT need a BBS
Perhaps I used the wrong term Rein, I meant mail server . Am I correct in thinking that a ham cannot connect to another ham and transfer a message, a server has to be used ? Andy - Pskmail does NOT need a BBS. Unlike winlink it works directly with any email account. Rein PA0R -- http://pa0r.blogspirit.com
[digitalradio] Propagation
I've been thinking, which is always a dangerous occupation Consistently I am able to work K2MO in Long Island,NY. by consistently I mean daily. This is a 2600km path, open all afternnon I regularly hear K6dww also a 2300km path and also CO2JA, Jose which is a 3700km path. whenever Any K3UK comes up, I can hear him as well. All this is on 20M between 12PM noon CDT and about 6PM .. start of Grey line. It would be interesting to see who can copy whom on 14106. With Tony's help I have mastered RSID so my station will respond to either ALE400 or 141A readily. Give it a shot or give a listen see who is out there John VE5MU
