[digitalradio] Windows7 drivers for Rigblaster?
I have a ham friend with a Rigblaster M4 and a new Windows 7 PC. He is using a serial-USb adapter. He says that Westmountain have been unhelpful via the telephone but he apparently needs a specific driver for Windows7 and his Rigblaster. Their web site is unclera as to which driver is needed for Windows 7. Anyone have a URL for the correct driver ?
[digitalradio] Re: Unknown Digital signal????
If you hear a rough-sounding and very broad signal centered at 3860 kHz there is a high probability that the source is a T1 data line within a half-mile or so. Internet data service provided by DSL, wireless, and various other means sometimes is referred to as T1 where the bandwidth approximates T1 bandwidth. However, they are not true T1 circuits and do not cause 3860 kHz interference. True T1 lines carry what is called a DS-1 signal. The data rate is 1544 kHz +/- 75 Hz. However, the transmission mode is bipolar using a code called Alternate Mark Inversion (AMI) which causes the pulse repetition rate to be 2.5 times the data rate. (2.5 x 1544 kHz = 3860 kHz) Signals at that frequency are sent in both directions down two 100-ohm twisted-pair balanced transmission lines that are often not shielded. Changing to shielded lines significantly reduces interference radiation. --- In digitalradio@yahoogroups.com, kc2axu liberty12...@... wrote: Hi ,,, got a question for you guy's...

Unless it is not impossible to disable busy detect, to answer your previous question about where to operate with Winmor, I personally think that Winmor frequencies should ALL be kept within the automatic subbands, since the tendency is going to be to disable it due to the uncertainty if there is malicious blocking or not. This way, busy detect can still be useful in enabling frequency sharing with other Winmor stations, and if someone disables busy detect, the effect on the rest of the hams will not be significant. This brings to mind the edict by Winlink that busy detect must not be enabled because of others trying to harm Winlink. It is highly unlikely that any malicious blocking will be done in the automatic subbands, because there is no reason to do so. The only blocking will be if the frequency is already in use by another mailbox. The recently reported problem with a PSKmail server still interfering with JT65 points up to another reason that ALL mailbox stations need to be in the same area, regardless of bandwidth. The more narrow the bandwidth, the easier it is to find a clear frequency there, so there is still an advantage to using a more narrow bandwidth. The frustration of being blocked too often if operating in the general use areas is, sooner or later, going to result in operator deactivation of the busy detection, especially as more and more Winmor mailboxes are set up. Before things get to that point, I think that it would be wise for early adopters, such as yourself, to set a good example by operating Winmor only in the automatic subbands and using the busy detection feature to more efficiently share frequencies there. 73, Skip KH6TY On 6/27/2010 8:46 AM, Andy obrien wrote: Skip (and anyone else interested), see the attached screenshot showing the Winmor server busy detect Andy K3UK

ALE400 forces the user into one software package and operating system at the expense of others.

Of course, I like where you are going with thatI'd much rather see multiple channels of narrow-band ALE in the bandwidth of one normal ALE signal. Another proposal might be to limit the ALE (and Pactor III that was proposed) to only one of the 60m channels, while allowing voice on all the others. I think PSK31 was also proposed, but I suspect that it was included simply to throw people off of the trail of ARRL's 60m EMCOMM grab. The problem with trying to setup 60m as an EMCOMM band (supporting ALE, Pactor III and the like) is that on 60m, we are second class citizens. The same characteristics that make 60m attractive to hams during an emergency make it attractive to the government as well. As long as we have to operate on a not-to-interfere basis, 60m will never be a viable EMCOMM band. FEMA, DHS, MARS, and others will grab all of the spectrum and there will be no room left for amateurs during a true regional or nationwide emergency. We already see that with the request to move one of the 60m frequencies due to continuing interference from a permanent station on the freq. I'm sure all of our other frequencies have government-authorized users that WILL show up during an emergency, effectively removing one or more channels on a regional or even nationwide basic.

[digitalradio] Neby help with digi modes
Welcome to the group. I have a TS2000 and also an SDR-IQ, I will be glad to help in anyway I can. Being an old-time digital mode enthusiast, I tend to suggest that rookies start the way almost all of us did with Digipan. Free, good, and the easiest to set-up. FL-digi and Winwarbler are perhaps the next easiest. You can start receiving digital modes easily by taking the audio out source (headphone or ext speaker jacks) and connecting it via a cable to the line IN of your computer's soundcard. There are some that worry that the audio could be a little to hot and blow your soundcard, I have done it LOTS of times before and never had a problem. To be on the safe side, you can lower the LINE IN audio level in you computers sound card mixer settings. Simply doing the above will allow you to copy all digital modes supported by your software. 95% of the digital modes you are ever likely to hear are either PSK31 or RTTY. So When it comes to transmitting and receiving, you will need to also connect your transceiver to the computer so that the tones generated by your software and sound card are sent over the air. Thus you have both IN and OUT of your sound card connected to your rig. You can also achieve control of your rig via the software and cause the rig to change frequency, transmit or switch to receive (and a few other things). Do do this, most hams have an interface that goes between the rig and the PC. The interface can be built for about $25 worth of parts, but many hams buy one. These interfaces range from the very simple and effective to the very sophisticated and effective . Some use circuitry that achieves full computer assisted operation and some do do it via simple use of VOX (Signal link). For most operations VOX will be fine but there are some more advanced applications that cannot be used via VOX.

[digitalradio] Re: Network 105 / Multipsk/ New idea
As many people know, I've been trying varying ideas of a way to post information on-line about who is QRV. Sked pages, HRGnet, Hamspots, etc, etc. In thinking about Network 105, I remembered the old MHEARD packet command and how easy and convenient that was. The fact that 300 baud packet is not as robust as modes like Olivia may actually serve a useful purpose. If you hear a signal on 300 baud packet, chances are you can work it with other modes. If you really want to talk to a particular station and the path is marginal, you could use the network part of Network 105 and go in via a node . If you establish a connection keyboard to keyboard , and do not wish to tie up the frequency, then you could QSY and pick a different mode. Of course , this is just one band, but if the idea takes off...maybe there would be a 30 or 40 frequency for times 20M is dead. With 10M radio selling for $25.00 at hamfests nowadays, I am also intrigued about a 10M network of low powered (25 watts) packet stations that could be quickly utilized. This would allow dedicated full-time packet stations and free up the main rig for other operations. Multipsk installs easily on older computers, so that old laptop of PC laying around your basement could also be part of a dedicated station, or that old TNC you have not used in years (I have two!) Just a few random thoughts from me, but Sholto and Tony's experiments have established that this mode and network while old school could actually be a viable tool in this digital mode age.

The path simulator indicated that the mode is especially sensitive to channel distortion so I would expect throughput issues if the ionosphere became somewhat agitated, regardless of how strong the signals where. PathSim's NVIS simulation tries to emulate a situation where ground waves interfere with NVIS sky waves. The delay between the two signals can destroy throughput so this is something to consider if the other guy is close enough to hear via ground wave.

Pactor has some but limited busy channel detection capability. WL2K is now looking at and testing alternatives to the conventional scanning used in Pactor. The new WINMOR protocol allows more options and experimentation. a. RMS WINMOR server stations [Beta operation started in January 2010] operate on ONE frequency which can be changed (on the hour) during the day (most use 1 - 3 frequencies over a 24 hour day). The frequency list clients use indicate which frequency is in use on which UTC hour. The client software (RMS Express) shows users ONLY those frequencies in current use along with the propagation prediction to the remote server stations. Users can refresh their server station list over the air or over the internet if available. b. WINMOR uses an effective channel busy detector to warn users if a channel appears busy in the bandwidth of interest. The detector isn't perfect (neither is the human ear!) but it can detect most modes even in weak conditions (SSB, CW, PSK, Pactor, Olivia, WINMOR etc). c. The RMS WINMOR stations (servers) also have a similar DSP based detector which can block a reply to a connect request. This will prevent for example answering a connect request over an existing session/QSO not audible to the station originating the connect request (hidden transmitter situation). We're still experimenting and refining this but it definitely helps avoid accidental interference. I can attest to the above., especially the ONE frequency part. The system works well Andy K3UK via HF WINMOR :)

Interesting observations John. I can't offer any useful insight, but look forward to hearing from those that can. Andy K3UK --- In digitalradio@yahoogroups.com, vk2eta vk2...@... wrote: To Tony (K2MO) in particular, but not exclusively: Following your simulation results on these modes in January I have done a few tests in the field and I have to say that I don't understand the results. Please note that I am not trying to make a point, but to understand why the theory does not seem to match the practical side. My tests simply revolve around examining the bahaviour of the Pskmail server adapting speed to the conditions. We have in the latest version a table of modes that the server can use by shifting up and down, one mode at a time. It does so by relying on the s/n report gathered from Fldigi and the number of repeats due to damaged ARQ frames. The list is arranged in an empirical order of speed vs robustness and is the following for regions 2 and 3: THOR8 MFSK16 THOR22 MFSK32 PSK250R PSK500R PSK500 The MFSK/IFSK family of modes are normally the modes of choice for NVIS. This week I did some tests at 95 miles in a strait line from my server on 40 and 80M between about 1PM to 2PM local time so obviously in NVIS conditions. What I noticed every time I would connect in MFSK16, the server would progressively shift the TX mode up into the PSKR modes, up to PSK500R, but never to PSK500. I also noticed that there would be no fallback from PSK250R to MFSK32 after a shift up from MFSK32. So my interpretion is the following: If the PSKR modes had a weakness in NVIS conditions, I would see the server moving continuously between MFSK32 and PSK250R: good reception in MFSK32, speed up to PSK250R, poor reception, return to MFSK32, etc... Also since it did not go up pass PSK500R to PSK500 it indicates that in these particular cases the PSK500R modes was starting to show signs of limitations and the server calculated that there was not enough s/n margin to shift the speed up. Selective fading is very visible especially on the PSK500R mode of course. So my question is: in the simulation you performed, are there parameters that maybe would need to be looked at to explain why these modes seem to behave well in these conditions or are there other variables to consider? Also trying to get a more formal comparison, how would you design some practical tests that minimize the effects of variation in propagation in the field? On this point I was thinking of sending a set text in different modes and repeating the test several times, interleaving the modes so that in average it would be unlikely to be just propagation. Mode1, Mode2, Mode3, Mode4 then again Mode1, Mode2, Mode3 etc... repeated say 5 times. Then taking the average result for comparison.

[digitalradio] Re: Not Tech Digital, But Then Maybe? SDRs
Kevin, FYI...here is a little email i sent to another ham last week on the topic. Hi, Roger. Regarding my SDR. I find it to be both great, and a bit of a pain!I did not want to spend lots of money, nor do I possess the skills to build an inexpensive one from a kit. My very talented friend , W3VG, bought a softrock kit 3 weeks ago and despite his talents, he is finding it quite a challenge. So, I bought a SDR-IQ for $499 after selling a 21 year old TS-440 for around $400. Having wide (up to 190 khz) spectrum to visually see signals is really amazing, hard to imagine being with out it now. Visually spotting DX is much easier than twirling a dial, you also find stations not yet announced on a DX cluster. On a crowded band, it is not as useful because it can be a pain to click on hundreds of signals. However, on a no-so-active band, it is fun looking for tiny whispers of signals and then hearing a CQ call. My SDR has the ability to listen with 3 VFOs (depending on the software used), so you can actually hear three different parts of the spectrum at the same time. I also can have two signals , one playing via the right speaker and one via the left, if I choose. I can also listen to LSB AND USB, CW and SSB , various combinations ...at the same time. I find the sensitivity to be not significantly different than my TS2000, if I can hear it on the TS200, I can usually hear it on the SDR-IQ. There is a bit more white noise hiss on the SDR but I can handle that. You can use noise reduction features, but I usually just ignore the noise. There will probably be times where my TS-2000 hears somethings the SDR-IQ does not, but not on a regular basis. If you do CW work, CW Skimmer is great with an SDR. It will find all the CW signals that are sending a CQ within the 192 hz span (or more if your SDR allows) and list them on a screen for you to click on and QSY to. Very useful. The pain in the neck part is two-fold. One , transmitting on one antenna and receiving via the SDR on another, is a hazard. If not careful, you can blow the front end of the SDR if too much RF gets in. I bought a device that protects the front end , there are 3-4 types available. This apparently applies to ALL SDRs, not just the SDR-IQ. The SDR-IQ designer tells me that the ONLY way to be 100% safe is to disconnect the SDR while transmitting. That can be a pain. What I do is.. I have a coax switch on my desk and I switch the SDR's antenna to ground before I transmit. So, there is that added step. Not a major hassle unless doing rapid fire work, like in a contest. Having a dedicated SDR transceiver using just one antenna would presumably solve this problem. The commercial devices you can buy either detect the RF and invoke protection circuits (the one I have) or use a PTT line and switch the antenna to ground (more expensive, $120) There is an application , called rig-sync , that I use. One click of a mouse and my TS-2000 moves to the frequency and mode that my SDR is in. Very useful.I also have a Microkeyer interface, with the software that comes with that, I can also control my TS--2000 AND SDR-IQ My SDR does not require a high end sound card, some others do. When you run an SDR, you can SEE large chunks of spectrum, but you can't hear large chunks. Some SDR software allows your to hear as much as 12 khz of audio, others just 3-6 Khz. That is not a big problem because your ears can not handle all those signals. Where it is an issue is for digital modes. Digital mode software has not caught up with SDRs yet. All, except Multipsk, will decode whatever audio spectrum you can get out of the digital mode software. usually around 4 khz. So, even if the SDR software allows larger chunks of audio, FL-digi, DM780, MixW, et al, will not decode more than the standard. Multipsk has a feature that WILL decode from an SDR directly. 48 Khz of spectrum is monitored and it will even detect RS-ID over that entire range, VERY cool. Multipsk does not support all SDRs...yet . So, in my case', it accepts the signal and works nicely, BUT I have to 'start the SDR-IQ via SDR software. Thus I have two CPU demanding applications running and it taxes my low end PC. My sons Optiplex 270 with a 2.7 CPU runs all of this without problem, so it does not take a whole lot more CPU. Multipsk may soon include more SDR support and then I would not have to use two applications at the same time. DM780 is also expected to add SDR support. Some SDRs like Sofrock can only do a small chunk of spectrum at a time (around 40 khz) , some do the same as mine (192 khz) and some (in the $1000-2000 range) do 2-3 mhz broken down in to several chunks per band. If I was doing it again, I would think more about getting the ability to monitor ALL bands. I did not consider a Flex radio because that requires a high-end sound card and computer, by the time you are

The PSKmail 1.0 digital communication system is largely mode-independent. Both uplink- and downlink modes are separately adapted to fit he channel conditions in such a way that efficient use of the channel is guaranteed. In the PSKmail client/server system, the server controls timing and Rx/Tx modes. To enable this, fldigi has been extended by VK2ETA to report avarage Signal to Noise ratio values and Mode changes during a session. The PSKmail protocol was extended to carry SNR values and mode indexes. Using this information the server can control the modes so that on both sides of the communications link the number of ARQ repeats is kept within certain limits. The system uses PSK500, PSK500R, PSK250, MFSK32, THOR22, MFSK16 and THOR8, and a mode is shifted up and down the table when appropriate. Intelligent RSID control == The PSKmail server also controls the RSID function on client and server. When idle, the server usesRxID. As soon as a session is established, the server closes RxID and uses TxID to make sure theclient is listening in the right mode. This is only necessary when a mode change is involved, so normally no time is lost on unnecessary RSID frames... Limiting repeats to loose less time... As soon as more than one ARQ repeat is necessary the server degrades the mode by one step, to make sure the client gets the next one correct. The server constantly monitors the channel quality both ways, and also uses ARQ success to decide on mode upgrades. Using this system allows fast and flexible response to QRM like ALE sounding or Pactor connect requests trying to take over the channel while a session is in progress. The system just waits until the ordeal is over and carries on with the session... Using new Fldigi-3.20 = PSKmail 1.0 only works with Fldigi-3.20, which has the new support features for PSKmail built in. A client upgrade to jPSKmail 0.4.9.9 (beta) is also necessary, and the server version with the new goodies built in is pskmail_server-1.0 (at the moment alpha2). The new client beta is available for experimenting and beta testing on http://hermes.esrac.ele.tue.nl/pskmail , SM0RWO has provided installers for windoze, Linux and Mac. The server test software runs on PI4TUE, SM0RWO and IS0GRB-3 on 10147.0 kHz (center frequency).

Set both the initial server and client modes to the PSK500R default to start with. If a connect is not possible you could try MFSK32 or MFSK16 to call the server. Once the session is established, both modes will change to fit channel conditions... After beta testing, the client will get version jPSKmail 0.5, commemorating the first PSKmail email exchange between KH6TY and PA0R, from a parking lot near le Havre, France, now 5 years ago!!

Double-clicking a PSK Spot Database Entry in SpotCollector directs WinWarbler or MultiPSK to immediately begin decoding the spotted station, QSYing the transceiver as required to achieve the specified optimal offset. Alternatively, one can click a plotted DX spot on DXView's World Map or click a DX spot on Commander's bandspread to accomplish the same result. WinWarbler's broadband decoder continuously identifies active PSK QSOs within the receiver bandpass, listing the decoded callsigns in its Stations Heard window. Optionally, these callsigns can be inserted into SpotCollector's Spot Database, where they are color coded for need with respect to the user's award objectives and award progress, dynamically obtained from DXKeeper. Thus its straightforward to identify needed PSK DX. These capabilities have been in broad use by DXLab users for many years. 73, Dave, AA6YQ

I would suggest 14109. Anything from 14101 to 14112 should work but Winmor is often at 14112. PACTOR is everywhere in this range but that is just the way the band can be. 14101 has been good most of the day but 14102 is a common frequency for Olivia, see below. +8h EA3AQS Spain14102.41OLIVIA DL7JP +8h OH/DK4ZC Finland14102.52OLIVIA DL7JP +8h EU6PW Belarus 10141.97MFSK16 G0UZP +8h DM2AUO Germany 14103.28OLIVIA DL7JP +8h DM2AUO Germany 14103.27OLIVIA DL7JP +8h DM2DTH Germany 14102.25OLIVIA DL7JP +8h IK4G Italy 14102.52OLIVIA DL7JP +8h IK4GBU Italy14102.51OLIVIA DL7JP +8h OH2HN Finland 14102.49OLIVIA DL7JP and 14101 is common for packet, I think.

[digitalradio] Protected HF frequencies
Actually John, I am beginning to think that there could be merit in protecting some frequencies for certain use . Maybe the PACTOR, WINMOR, PACKET, ALE, PSKMAIL, unattended stations SHOULD get a small slice of spectrum. They would help in the event of emergencies , and keep the rest of band free of QRM from them. There perhaps could be some threshold to meet in terms of usage and in determining which method is worthy of protecting. I'd suggest that they get 5kHZ of 80M, 60M (yes , 60) , 20, and 10 , no other bands.

Many advanced digital protocols manage the spectrum in the SSB bandwidth to achieve performance. But since the implied carrier frequency is not moving, it's not spread spectrum in the classic sense. It does not matter what the ROS authors write to describe it. It isn't illegal in the USA because they call it SS, all that matters is how a competent engineer would technically describe it. FCC rules do not say it is illegal to use a mode that describes itself as SS on HF, they say that SS is not allowed on the HF bands. And saying ROS is SS doesn't make that true. I also agree with Andy G4JNT's point that Amateurs should be allowed to experiment. Historically in the USA, the FCC has indeed allowed experimentation, then come along with appropriate rules once the new technology is better understood.

[digitalradio] ROS impressions so far
In the few ROS 16 and ROS 1 tests that I have dome so far... ROS 16 seems similar to Olivia 8/1000 , good performance but perhaps a not quite as good as Olivia under QRM or deep fades.

Hello My call is F4AWY and i am a beginner in digital mods best 73 from France . Welcome to the group, please tell us what modes you use, we will be happy to help with any questions. Andy K3UK
[digitalradio] Re: Introduction and question
Welcome to the group, Wes. That is an interesting question, I look forward to seeing other answers. My answer is rather vague and generalized . I'm going to argue that reduced power is not really the issue, but that reduced power is often associated with no ALC which most point out is a key in not having a over-driven, distorted , signal . I say most because not every ham agrees with this, some thing ALC is not that much of a factor. The prevailing view is that most soundcard modes should not be showing ALC, PSK31-250, Olivia, AFSK ,RTTY, etc, but some modes like JT65A are less prone to this issue. FSK RTTY is also not a mode that would be impacted by this issue. Consider this from PSK Fundementals by Peter G3PLX (http://aintel.bi.ehu.es/psk31theory.html). Also see http://www.eham.net/articles/12626 The Good Bad and Ugly on PSK31. There is a problem with PSK keying which doesn't show up with FSK, and that is the effect of key-clicks. We can get away with hard FSK keying at moderate baudrates without generating too much splatter, but polarity reversals are equivalent to simultaneous switching-off of one transmitter and switching-on of another one in antiphase: the result being keyclicks that are TWICE AS BAD as on-off keying, all other things being equal. So if we use computer logic to key a BPSK modulator such as an exclusive-or gate, at 31 baud, the emission would be extremely broad. In fact it would be about 3 times the baudrate wide at 10dB down, 5 times at 14dB down, 7 times at 17dB down, and so on (the squarewave Fourier series in fact) The solution is to filter the output, or to shape the envelope amplitude of each bit which amounts to the same thing. In PSK31, a cosine shape is used. To see what this does to the waveform and the spectrum, consider transmitting a sequence of continuous polarity-reversals at 31 baud. With cosine shaping, the envelope ends up looking like full-wave rectified 31Hz AC. This not only looks like a two-tone test signal, it IS a two-tone test signal, and the spectrum consists of two pure tones at +/-15Hz from the centre, and no splatter. Like the two-tone and unlike FSK, however, if we pass this through a transmitter, we get intermodulation products if it is not linear, so we DO need to be careful not to overdrive the audio. However, even the worst linears will give third-order products of 25dB at +/-47Hz (3 times the baudrate wide) and fifth-order products of 35dB at +/-78Hz (5 times the baudrate wide), a considerable improvement over the hard-keying case. If we infinitely overdrive the linear, we are back to the same levels as the hard-keyed system. Andy K3UK --- In digitalradio@yahoogroups.com, w1...@... w1...@... wrote: Greetings.

[digitalradio] Re: Time for a Digital Skimmer ?/Hamspots and PSKreporter
After thinking about this some more... I think that most of what I want IS available . DM780, Multipsk, and Fldigi all report to PSKreporter. Hamspots picks data (filtered for redundancies, perhaps redundancies can be allowed/toggled ? ) FROM PSKreporter and displays in a non-graphic intensive manner. http://www.hamspots.net/home/ e.g. Cluster PSKReporter Spots Age Spotter DX ST FreqMode 3m N7PAT N7MNK United States, ID ID 3580.00 PSK31 4m W6JMP KB5WMM United States, TXTX 7035.00 PSK31 4m IW4EGP F5CAC France1838.00 PSK31 4m W6HGF W0EAT United States, CO - lotw CO 3582.54 PSK31 What does it NOT provide that the CW guys get via CW Skimmer? Not ALL digital modes are available on Hamspots in one place, as far as I can tell. It does not alert to QRL, 5NN, or CQ. You can't custom filter the information, yet (you can to a degree at PSKreporter). and as Wes pointed out. you can't telnet to the data and then filter in something like Spotcollector. WI\ith Spotcollector getting data from CW Skimmer , you have a really powerful custom tool for alerting all kinds of things. So we have two sites, one with cool maps and LOTW spotting assitance. one with just text. Pretty close to what we need, two nice choices. With DM780, Multipsk, and Fldigi being very well used these days, you have a potentially much larger pool of skimmers/reporters than CW Skimmer has on the CW side. Of course, one major issue is the fact that unlike CW and Skimmer, digital mode hunting involves about 10 common digital modes . The software does not allow reporting of multiple PSK31 reports from the passband AND any other mode detected via RS ID (you can do one of the two, not BOTH). You can achieve this as I mentioned last week by running 2 apps at once...one decoding PSK31 in panoramic mode and the other waiting for RS IDs. It seems to me that Wes' point about Telnet access is perhaps the next important advancement, then perhaps an ability to decode multiple PSK31 signals AND trawl for other digital signals via RS ID at the same time. Meanwhile, lets get as many of our reception reports sent to PSKreporter and subsequently to Hamspots. --- In digitalradio@yahoogroups.com, Wes Cosand wes.cos...@... wrote: On Tue, Jan 12, 2010 at 8:19 AM, Andy obrien k3uka...@... wrote: I have no clue how... but could the data get to look like the data at http://www.reversebeacon.net/dxsd1.php?f=6 ?

Using the logs, it is possible to offer band-mode league tables, efficient log search tools, analysis for DXpedition planning purposes and most wanted lists for DXCC entities (including by date, band or mode for example). There is a great deal of information that can be mined and analysed in a standard ADIF file. Club Log can provide empirical propagation charts, and give back to its users the ability to find wanted DX spots, identify QSLing gaps and perform other analysis of their logs which might be hard to do with normal logging software. Through Club Log, I also host online log search systems for significant DXpeditions. One of the driving principles of Club Log is to store as many QSOs as possible, as this makes the reports and statistics more meaningful and representative. Everything in Club Log depends upon analysing real QSOs, and or this reason I am very grateful to everyone who participates.

Today when trying to work a needed entity , and with a fading band, I had to patiently wait my turn while others that had got through were sending such none sense as how many QSO's they had had in the particular digital mode and the exact time and date they had logged the QSO.

[digitalradio] Re: Need your help picking HF radio.
The TS2000 has lots of bang for the buck, HF, 2M, 6M, 70 cm, IF DSP. The TS480 has been labeled by some here as the best radio for digital modes. Icom746 Pro has good reviews. Icom 7000 also. Features, I am no expert in this area,but ability to control or at least turn off/on the AGC is important for digital modes. This helps reduce the problems associated with strong nearby signals using digital modes. Ability to easily dial in narrow filters while in USB (not just CW) also helps with digital mode QRM.

Non smoking environment. Never used as mobile (does not include mobile mounting bracket). Stock hand microphone. I am selling it because I rarely use it now that I have a TS-2000. It is in good working order but the light bulb at the S-meter does not work, While working fine, outwardly it does have a few marks from taking it to Field Day and other demos. All else seems to be fine. The tuning knob seems slightly stiff compared to my TS-2000, not sure if that is because the TS-2000 has a smoother system , or because the TS-440S is aging. I will make a youtube video of it working upon request. Has NOT been modified for transmission outside of bands. It has been modified to display digital readout to extra decimal place. No printed manual (you would not want the manual after what my cat did to it) but manual is available for free on-line. Great transceiver for new or experienced ham. Andy K3UK
[digitalradio] wsjt7 -- DBLog

When the new wsjt.py starts it tries to connect to DBLog in TCP on port 3164. If this succeeds, double-clicking on a received call, sends it to DBLog. DBLog will show it in the main window and,eventually, the list of the WB4. When the QSO is finished, clicking on Log QSO of wsjt will log the QSO also on DBLog. Exiting wsjt will disconnect from DBLog. On the site there are two screen-shots and a tarball of the wsjy7 that I have used. This last one has been produced by IK1CHE from the SuSE distribution. It compiles well on my Debian 5.01; it just takes to copy by hand KVASD_g95 into /usr/bin. Read the INSTALL for more information. best 73 Pino ZP4KFX pinozollo at gmail . com --

[digitalradio] 1995 QST item on ALE
From 1995 in QST ALE Disadvantages There are a couple of detractors related to ALE that exist for amateurs. These are frequency selection and interference problems. Unlike the government, which has a greater selection of frequencies, amateurs are confined to specific bands. ALE requires a wide range of frequencies to select the best channel. In addition, the initial linking call could interfere with other digital signals on that same frequency. You must listen before transmitting or attempting to link. I can see how regulation and much discussion needs to take place before ALE will become practical for amateur use. It can be a reality#63719;if the minds of many solve the problems that face our unique situation. Looks like the minds of many have not met despite 15 years to solve the matter. Andy K3UK
[digitalradio] Dx pile ups..
Bonnie said the same goes for DX pileups. Basically, a pileup is simply a contest where the number of possible contacts is 1 and the number of possible multipliers is 1. Everyone who enters the pileup contest is trying to out-QRM the other entrants, or in FCC parlance... to harmfully interfere with, the other contestants in the pileup contest. They are trying to keep the other stations from working the target station, in favor of themselves. Louder, stronger, QRMer. Surely Bonnie is correct in this? Not ALL DXers , but the vast majority are doing what Bonnie describes when responding to a QRZ. If I hear P5DX QRZ?, then I hear November Seven Delta... starting a call and throw in Kilo Three Uniform Kilo on top of the 7 station (Danny) , Bonnie is correct that I have QRM'd him. I guess the difference is that this is accepted and actually encouraged. I still remember my utter shock when a new ham reading the ARRL handbook about DXing, and how a DX station would listen on incrementally different QRG and NOT tell you exactly where. The book explained that the art of DXing was to determine the DX station's methods and skillfully figure out where he would be listening. In Bonnie's context, this would be encouraging lots of QRM . Skip's earlier point would be that this still differs from unattendned transmissions but I think Bonnie's point is that the result is not that much difference. Cue Bonnie with comments about goose and gander... Andy K3UK

[digitalradio] Re: Question of beginner
Hello Nikos, welcome. It is a good question. The answer is a combination of ear, eyesight, and software. You can actually hear what each common mode sounds like by using software and pressing transmit. Even if you are not actually transmitting, you can then hear what the mode sounds like. When using you eyes, look at how wide it is in the software's waterfall. PSK31 will be approximately 30Hz wide in a waterfall, PSK63 twice as wide. RTTY will be about 170-200 Hz wide. Olivia, Thor and other modes will be about 500-1000 Hz wide. Telling the difference between the different Olivia, Domino. and THOR modes takes more practice. To my ears, Olivia has a distinct two-tone start up tome that sounds like an old French ambulance siren.Is you use software with RS ID , the sofwtare will tell you IF the other station is also transmitting an RS ID at the beginning of their transmission.

[digitalradio] WINMOR more
So, a few weeks ago WINMOR was just a concept to most of use. Now many have tested the simple soundcard alternative to $1000 modems and the verdict appears to be... it works ! It works as an email/file sharing digital mode but not perhaps as a strong competitor to Pactor III in terms of performance. I think the authors and development team will probably point out that they never intended to have the mode equal or better PIII , rather simply provide an alternative that was effective on HF. While there are a few problems still being worked on, my views is that even if they never made any more improvements...their goal has been achieved. While some WINMORons (I think that is what we should call ourselves) have achieved transfers in the 1000 to 2000 bytes per minutes range, I have been mainly in the 200-400 range. It still works though. The next stage will perhaps be the most interesting, switching from experimental peer-to-peer email exchanges and incorporating WINMOR fully in to the Winlink suite of applications . From a emcomm point of view, the ability for a RACES station to simply be able to send traffic via packet and Telnet, PLUS have a HF server accessible without needing a $1000 modem , will be very helpful. How the bands will be with ping-ponging mail exchanges is another matter, I suspect some will not be happy. The busy detect in WINMOR does work though, that should help. Andy K3UK
[digitalradio] FLARQing fun
Anyone want to test FLARQ with varying modes this weekend, please consider the following dial frequencies. 10147, 7082, 3583, and 14073 USB (all dial frequencies ). 2 years ago I met with Skip KH6TY (or was it three years ?) and he gave me a beta copy of NBEMS FLARQ. I thought it would become one of the mostly widely used digital application for emcomm work. I was wrong, it kinda fizzled . However, slowly but surely the application has impressed ARES and RACES groups in the USA . I think we will gradually see even more use of FLARQ. Winmor has not fully impressed me yet. I am impressed by the effort Winmor programmers have made and impressed that overall the application works. However the state of the science at this moment is that FLARQ with a variety of modes to choose from, and modes less fussy about sound card timing, is likely to be more effcient during emergencies. This is perhaps an unfair comparison for WINMOR since FLARQ is a few years old and WINMOR just a few months. Andy K3UK
