Re: [digitalradio] 160M digital meeting place
I have been using the bottom part of 160, since I started with 160, without anyone complaining. That is, after we were allowed the whole of the band, and didnt have to fiddle around trying to stay out of the radio location areas. Those were a real pain, having been in different portions of the band, for different areas of not on the country, but the world. Back then, having a DX window, etc. made some sense, but no longer does. take DX where ever it is. I have had people come in and say I am in the DX window, when I am working DX.

Re: [digitalradio] Remotely controlled radio with full connectivity.
I currently have a remote HF base. I have tried Ham Radio Deluxe which worked fine, but prefer TRX-Manager, which controls the radio, the SteppIR, the rotator, and the band switch for the linear, and the band switch for the antenna. For functions not controlled by TRX-Manager, I use free remote desktop software called LogMeIn. This is just like the more well known GoToMyPC, except it is free. Once I am on the remote PC, I can use RS232 relay boards to select which receive antenna I want to use, etc. The best remote control radios are the Kenwood TS-570, 870, 480, and 2000. Not necessary the best radios per se, but easiest to remote. I originally used the obvious audio solution, Skype, but now use IP Sound from SM5VXC. I am working on doing audio over a phone line. This is the best solution, and long distance rates are now so cheap I can afford to use it. There are many other remote configurations different from mine. They all have advantages and disadvantages and what works best depends on your particular situation. You should probably read the Google group on "IRB" (internet remote base). You might want to start out operating one of the public remote base stations. What is harder than the above is getting an internet connection to the remote base. And getting the remote base venue itself is harder yet. But that is OT for this reflector.

[digitalradio] Remotely controlled radio with full connectivity.
Here is what I was thinking, to setup a radio at a remote location that could be "fully" controlled remotely. Ham Radio deluxe has the capability of controlling my ft897 with a serial interface. A USB sound card could be used to provide PSK and other digital modes. By using this remote usb interface http://www.digi.com/products/usb/anywhereusb.jsp a remote serial interface and sound card could easily be setup. Is there a way to pass audio through one sound card to another sound card? In this situation it would be nice to talk SSB using the computer mic and speakers. Is there a way to speak into a mic and have the sound come out another sound card and then the reverse when recieving? Any help is greatly appreciated I am so excited about this concept. This would allow an apartment dweller like myself an inexpensive way to have a completely remote full HF rig. Best case scenario would be to purchase antenna and rack space on a mountain top.

Re: [digitalradio] Can I get a rig with MORE?
Howdy: The board brush strokes are easy. I do not have enough patience, smarts, or time to do what Bob Cowdery has done in his fantastic erlang implementation. On the other hand it does not fit with my vision of this and so far, Frank agrees with what I have been saying so I am assuming it is substantially his vision as well. The idea is to have the erlang be the simplest possible thing, as few lines as possible to get the job done reliably, robustly, with remoting built in from the word go. Cnodes are big in your future. dttsp's sdr_core (as an example) will start up as a stand alone program and it will maintain its command structure. Now you use the simple cmdr script to send it commands. e_cmdr will be a C program that starts up and attaches itself to the TINY erlang server. After it establishes its presence, it will negotiate what it can provide and what it wants to receive. So long as it is around, the erlang based hub will send all commands of the registered type to it and respond to all data requests of the type registered from e_cmdr by making a request for this data from e_cmdr, etc. The state held in the erlang radiocore will be the absolute minimum needed. If the cnode disappears, the hub will time out on it and drop it and all of its sources and sinks from the list. You might think of the, erlang cnode as working the exact same way Frank did the code in update.c BUT the "CTE" array will be dynamic and supplied upon initial connection, etc. in the radiocore. It really will be TINY block of code and the smarts will be in the leaves. I have had Cnodes running robustly on all my machines of every type for months. I keep thinking that it is but a day's work to give everyone the e_cmdr as a template for how to make their connection to the hub and even to provide the simplest possible kind of GUI, something like Roger's little push button GUI but interfaced through its own Cnode interface to the hub as a template for how to proceed. Between having FOUR close relatives with life threatening conditions and being constantly on the road for work, I just have not gotten it done. I apologize to everyone. No one is more unhappy about this than me. I need an uninterrupted week at home. This week I am in Boston fighting the snow going to Cell processor class at Mercury and next week I am at VPI working on OFDM with GnuRadio folks for MY WORK. I will catch a breath soon.

Walt: Frank, Eric, and I have specfically answered all of your questions about the Linux support. It is completely controllable under Linux now especially for those who have no need for fancy radio GUI's. For those that need GUI's there ARE GUI's and more will be coming. Roger Rehr has painted the road with crayola crayon especially for you: http://www.nitehawk.com/w3sz but the Linux code does not have the polished presentation of the Windows version of code AND IT DOES NOT SUFFER FROM ITS LIMITATIONS. It is poised to take off now. There are several approaches to take such as dttsp-shell (available from Edson Pereira) or the java GUI done by John Melton or usSDR gui done by Jonathan Naylor.

Re: [digitalradio] Re: Domnio, PAX etc
I did some measurements for a few days in november on ionospheric doppler using whatever "constant" signals have been available, like WWV, CHU, several broadcasters on 49 meters, including Radio Habana Cuba, whose transmitters are some 20 km away from my QTH and become a mix of NVIS and ground wave. I used Spectran to obtain the carriers spectrum, and I mean plural, because you get several "threads" dancing on the screen in frequency and amplitude. I shifted the carriers to 1 kHz, offseting the tuning by that amount. The results have been interesting and a bit surprising. You may see several threads on the screen, spread around some 5 Hz. The frequency moves on the average at a rate of about 0.1 Hz per second (more or less, I was looking for absolute shift more than rate of shift, but both do matter). At times, some of the threads dissapear, and reappear shifted about 1 Hz per thread, sometimes jumping from one extreme of the carriers bunch to the other. The analysis bandwidth was between 20 and 50 Hz wide. I was also playing with Spectran and learning how to use it. That kind of behavior is a killer for many modulation schemes. As Patrick says, PSK10 suffers much more than higher speeds because the bit duration is an important fraction of the doppler shift rate, and you never get anything as stable phase. But also, when relative amplitude among the several threads varies, the carrier regenerator may jump from one to another. I did not look either for amplitude calibration during those first attempts. It may require periodic screenshots of the Spectran spectrum in the upper window. Reanalyzing some of those screenshots you may see amplitude differences as large as 20 dB at times and as small as 1 dB on some ocassions. But I was looking at the waterfall, and did not pay too much attention to amplitudes, and the screenshots timing was random between those patterns I found interesting in the waterfall. I don't know so far if Spectran might be able to produce a printed log of the amplitude vs. time distribution of the threads amplitude (possibly not...). Multicarrier modulations must also suffer, because if you use OFDM the jump from one of the "outer" threads to the other extreme, 5 Hz away, may be a cause for MT63 to refuse to decode at all sometimes. That is on the lower boundary of usable speeds. But you are bound also by ISI (inter symbol interference) at the higher usable speeds. One of the strategies of Pactor III is supressing some of the carriers at the lower data rates, and it sort of protects the signal by spacing the frequency bins a bit farther away, which may become more inmune of doppler causing the carriers to fall in the adjacent (wrong) bins. I did not measure delay spread, and would appreciate suggestions on doing so. And I only see the time standards (CHU, WWV) as suitable using the second ticks as time markers. I am open to suggestions. I cannot be conclusive about doppler spread now. It does not seem any worse on the higher frequencies, but then again, paths are different, and it does have an effect on what you get on the screen with Spectran. 73, Jose, CO2JA --- Patrick Lindecker wrote: > > Hello to all, > > There are also some basic axioms (I suppose so) as: > > 1) "Doppler iosnospheric modulation" acts on PSK modes (the phase is > "dancing" randomly, the Costas loop cannot stabilize and the PSK > decoding is quite impossible).
